With all sights set on expanding bandwidth and speed, 10/40 gigabit Ethernet promises to capture a lot of attention this year. 40GE switches are the new muscle cars that are beginning to power leading-edge enterprise networks. Virtualization and network convergence is driving huge volumes of traffic across data center switching fabrics. The capacity and forwarding performance of this fabric is critical to ensuring timely delivery of service and application traffic, and the associated end-user experience.
Network managers need assurance that network switches can scale to meet increasing traffic loads while minimizing traffic latency and power consumption. Switch performance benchmarks can offer network managers this assurance, but putting one of these beasts to the test requires an equally powerful test system capable of pushing the switch to its limits. Ixia’s data center test solution rose to this challenge in the world’s largest-scale, highest-density switch test to date.
Ixia generates 192 x 40G ports of wire-rate traffic to fully-load switch
In December 2011, Ixia’s IxNetwork and Xcellon-Flex, the industry’s leading 40GE port density emulation load module, were used to test Extreme Networks BlackDiamond® BDX8, the industry’s largest-capacity cloud switch. This independent test, performed by The Lippis Group, challenged both the switch and the test system. Xcellon-Flex generated massive amounts of real-world traffic to fully-populate the switch’s 192-40GbE ports (equivalent to 768-10GbE ports). Cloud test scenarios were designed to evaluate the BDX8 in the context of approximately 28,000 VMs and 700 physical servers.
“This is the first time, in the industry, that such a test of this scale and magnitude has been conducted. This configuration allowed us to measure the (BDX8) core switch at full capacity for throughput, latency, jitter, IP Multicast, power consumption and cloud simulation.” (Open Industry Network Performance & Power Test for Cloud Networks, Evaluating 10/40GbE Switches, pg. 20, December 2011, Lippis Report)
The Ixia solution precisely measured lowest average latency of just 2.2 microseconds, average delay variation of 5ns, and the fastest IP multicast performance measured to date (three times faster than any previous core switch measurement). In addition, the Ixia solution was able to test and measure the BDX8’s power efficiency in WattsATIS/port and TEER value.
Virtualized data center traffic is driving higher performance expectations for both data center networks and vendor products. Ixia's advanced load modules and test applications enable NEMs like Extreme to demonstrate city-scale performance under real-world, virtual network conditions.

Many service providers already have IPv6 supported in their core networks and have made significant progress toward supporting IPv6 on their access networks as well. However, compared to their service provider counterparts, enterprise IT departments are lagging behind when it comes to planning for IPv6 traffic.
With the IPv4 address pool exhausted, it’s become increasing important for enterprise IT departments to seriously look at IPv6. While the killer application for IPv6 remains elusive, IPv6 will improve operational efficiency for IT staff and network operators, and potentially improve application performance. As traffic switches over to IPv6, there will be a reversal of IP types and an exponential increase in IPv6 traffic will be seen in enterprises. This means that businesses will have to plan their IPv6 migration strategy very carefully so that they address problems specific to enterprises.
IPv6 migration is complicated by the myriad of legacy network topologies and existing applications running in the data center. One of the key decisions enterprises need to make is which data centers and applications need to be IPv6. How are user devices provisioned and can the network scale to support them? How are IPv4 or IPv6 islands interconnected via existing network connections for end-to-end service? These factors affect the selection process for which technology works the best for a particular network and has led to multiple competing migration solutions, such as NAT64, NAT444, 6rd, DS-Lite, and dual-stacking.
Application performance and user satisfaction will be the criteria with which IT professionals are measured as networks and applications migrate to IPv6. Understanding the implications that various IPv6 transitional mechanisms and security countermeasures have on application performance are important to empirically assess, because it’s better to avoid issues before a technology selection is made or before users complain about poor performance.
Enterprises need testing tools to ensure their networks and applications can support new IPv6 hosts, while at the same time maintain the performance, predictability, and reliability of their existing network services offered to customers. Testing IPv6 requires the emulation of the full range of protocols used in today's IPv4, IPv6, and transitional dual-stack networks, as well as fully stressing the data plane and associated tunneling/translation implementations for migration schemes. Application performance needs to be measured to understand how the underlying network topology will affect the end-user quality of experience.
To discuss these challenges, I will be at V6 World Congress in Paris as a panelist in the round table session Challenges that Enterprises Face when Introducing IPv6, Wednesday, Feb. 8, 5:30pm.
Economic and competitive pressures have led financial enterprises to make business assets and sensitive information accessible through IP networks, which are susceptible to attacks that steal money or affect the delivery of client services. Both can result in serious losses. It used to be that a bank’s assets were as secure as its vault. Today, financial enterprises need a way to protect their assets from distributed denial of service (DDoS) attacks, known vulnerability attacks, encryption attacks, and impersonations.
Vulnerabilities are most often exploited by manipulation of network protocols at all levels – from user input in URLs and web page form fields, all the way down to the bits and bytes in protocol packets. Vigilant financial enterprises need network testing tools for every stage of network planning, device selection, and pre-deployment, and at every network level and interface. Because systems are most vulnerable to failure when running near maximum capacity, pre-deployment testing should emulate realistic scale and traffic to stress the infrastructure that your financial applications rely on.
A number of tools are used to implement security for financial service providers, including:
-
Pre-deployment testing – components and networks should be tested before being deployed in live networks. Principal among the security tests are:
- Conformance – packaged tests that ensure that all supported network protocols conform to industry standards to help close security holes and ensure interoperability between network components purchased from multiple vendors
- Known vulnerability testing – a large number of tests that ensure services and applications have been updated and improved to resist historical attacks
- Performance – determines the maximum real-world performance of the financial service to ensure that each client is serviced with sufficient quality and to determine how the service performs under overload
- End-to-end encryption – because intermediate networks are out of financial service’s control, techniques must be applied to guard the client-server communications. This most often takes the form of browser-based encrypted connections using SSL or TLS.
- Firewalls – Firewalls admit or reject connections, handle DDoS and other attacks, filter outgoing information for confidential data, detect sophisticated intrusions, SPAM, and viruses.
Ixia will show its security solutions at the RSA Conference, February 27-March 1, 2012 in San Francisco. Register for a free exhibit hall pass (use Expo Pass Code: EC12XIA)

Operators have learned some very hard lessons rolling out 3G networks and are looking to avoid making the same mistakes with their new 4G/LTE networks. 3G is often referred to, in confidence, by network engineers at the large operators as “the best effort network,” due to its rigid and inflexible nature. 3G was not properly specified and, more pointedly, a lot of equipment supplied by vendors has proved unsatisfactory in providing operators with the tools to properly handle the rapid increase in data and video traffic.
The technical benefits of LTE are well-documented. However, it would be dangerously naïve to believe that the same network planning techniques should be used when rolling out LTE. We are very much at a cross roads, LTE specifications provide vendors with the blue print to build equipment for a more intelligent network. Leading operators are quickly shifting from the “get it working” stage of LTE to really analyzing how it will give them very granular and dynamic control of subscribers and service types.
The realities of 100 percent year-on-year traffic growth driving a need for 30 percent year-on-year CapEx growth do not synch well with three per cent revenue growth. Without having a finely-tuned network that maximizes revenues and deals with capacity issues, operators know they are in a perilous situation.
By working with the world’s leading service providers, Ixia has a first-hand account of how those carriers are preparing their networks to handle the most important trends in mobile broadband. With innovative test equipment and best practices for validating VoLTE, creative charging models, and the ability to make the move to business-grade video, we can help you build a smarter 4G/LTE network.
Atul Bhatnagar, Ixia president and CEO will speak on this subject at Mobile World Congress, Barcelona, February 29, 2012. He will share an insider view and his experience working with the leading mobile operators to prepare their networks to handle wireless security, VoLTE, business grade video, tiered service plans, and Wi-Fi offload.
Whether buying a house in the country, renting a bungalow in Bora Bora, or running a network, you’ll want one with a view. The ability to quickly and easily see how your network is performing is one of the most critical factors in ensuring a quality end user experience.
Successful service providers, enterprises, and government agencies all seek innovative technologies that can bring efficiency and competitiveness. These technologies enable bandwidth-hungry services such as voice over IP (VoIP), video, and enterprise applications that introduce potential network bottlenecks, which must be isolated and corrected.
With growing network complexity and expansion, Internet service provider (ISP) operations and IT departments need more visibility into their network performance and the tools necessary to quickly verify and diagnose issues, on demand or in a proactive way.
Ixia’s IxPro Experience Service Portal (IxPro ESP) is a new web-based test platform that leverages Ixia’s powerful network assessment tools. The comprehensive and intuitive interface is oriented toward service provider operations groups, and enterprise and government IT departments.
From pre-deployment to service turn up and post deployment, IxPro ESP simplifies network quality qualification and service level agreement (SLA) verification. Based on a very broad set of available active tests and KPIs, setting up tests and analyzing and interpreting results becomes fully intuitive through a full set of easy-to-use configuration pages, dashboards, and reports.
For service turn-up verification or site assessment for new technology introduction like VoIP, IxPro ESP offers a quick and efficient way to get full SLA verification within comprehensive html or pdf reports. Based on Ixia’s IxChariot software testing technology, IxPro ESP allows you to run quick ad hoc new line verification within a few clicks. IxPro ESP packages a turn-key solution with calibrated tests, so that the users can focus on test results rather than test setup.
IxPro ESP is also a post-deployment live network monitoring tool. The advanced network monitoring solution continuously probes the network for key performance indicators (KPIs) like loss, delay, jitter, throughput; proactively detecting and reporting network problems. The capability to test network segments and isolate between the network and application layers enables you to pinpoint issue location (network vs. application, network legs) quickly and reduce mean time to diagnose (MTTD) and mean time to repair (MTTR).
In addition, the view of your network offered through easy-to-use, customizable reports, dashboards, and alerts makes IxPro ESP a comprehensive, affordable solution for active field testing for service providers and IT departments.
IxPro ESP is offered by Ixia’s professional services team of highly-experienced testing experts, who will help you achieve the optimal testing solution for your unique requirements.
Now that the IEEE 802.3ba is a ratified 40/100GE standard and commercial hardware products are available, service providers and enterprises are beginning to deploy higher speed Ethernet (HSE) networks to capture the promise of extreme scalability, performance, and cost-effectiveness.
We’ve seen many of our network equipment manufacturer (NEM), service provider, and enterprise accounts turn to Ixia’s HSE test solution over competitive products. Today’s success of our HSE solutions is a culmination of many years of research, planning, development, and thought leadership. Over the past four years, Ixia has played a major role in the definition and deployment of HSE.
Ixia has accelerated the development of HSE starting with our participation in the IEEE 802.3’s High Speed Study Group (HSSG) in September 2006, to a first-ever demonstration of 100G testing at NXTComm in June 2008, to hosting and participating in the world’s first public Higher Speed Ethernet interoperability plugfest at iSimCity in Sept 2010, to developing and delivering multi-vendor 100GE benchmarking tests with EANTC in July of this year.
Through the evolution of HSE, Ixia has demonstrated the viability of 100G network implementation with dozens of equipment vendors and service providers worldwide. Ixia is an active participant in the Ethernet Alliance’s HSE Subcommittee, and serves as its marketing chairman. This year, Ixia delivered the next generation of its HSE solution, with twice the port density of any other solution on the market. We remain on the leading edge of Higher Speed Ethernet technology. For example, at Super Computing 2011 (SC11), the conference organizers used Ixia’s solution to validate the throughput of its onside high-speed network, and several NEMS used our solution to demonstrate their high-density data center switches.
The timeline below is a testimony to our dedication to HSE technology, our product maturity, our leadership, and the extent of our global partnerships.
See Ixia’s extensive library of HSE resources, including product information, whitepapers, test reports, webinar recordings, vendor testimonials, and an HSE Black Book that includes test methodologies.
Software as a service (SaaS), an on-demand software delivery model that centralizes data and hosting in the cloud, has become mainstream because it saves companies time and money, and reduces CapEx. Touting similar benefits, testing as a service (TaaS), is quickly becoming a weapon in the arsenal of the over-extended IT departments and test labs responsible for verifying device and network performance, and service quality.
From network rollouts, upgrades, and migrations - to data center centralizations or cloud-based outsourcing, IT projects face complex validation challenges and quality of service (QoS) nightmares. Business-critical infrastructures and services have no room for mistakes in sizing or configuring, as outages can costs companies millions in lost revenue and lost productivity.
Pre-deployment testing and staging has always been the answer, but with the time and resource pressures of today’s economic climate and the ever-increasing complexity of converged networks and services, it is becoming more than IT departments and labs can handle.
TaaS is a rapidly-growing trend that bundles industry-standard test plans, reports, and methodologies with hardware, services, and software that apply to various aspects of an infrastructures’ lifecycle. It addresses the needs of QA labs and IT departments, as well as pre- and post-production networks and systems for carriers, enterprises, and network equipment manufacturers (NEMs).
Solving specific testing challenges, Ixia’s IxTest TaaS offering is used by customers ranging from large banking institutions, major consulting system integrators, ecommerce retailers, and network equipment manufactures.
Following is a list of new features and functions that will be available this month for Ixia’s IxN2X software and hardware products.

Ixia has drawn on its industry expertise and experience working with global customers, industry forums, and test labs to predict the networking industry's top trends for 2012. We expect growth to come from data center, wireless, security, IPv6, and Carrier Ethernet deployments. Check out our predictions for the following technology areas:
- Next-Generation Data Center
- Internet Security
- Cloud Computing
- IPv6
- Long Term Evolution, Mobile Backhaul, and the Evolved Packet Core
- Next-Generation Networks
1. Next-Generation Data Center
40- and 100-Gigabit Ethernet (GE): Virtualized servers will generate more traffic than 10 gigabits per second (Gbps) connections can handle. Currently, only a few data center switch vendors support 40Gbps ports. In 2012, we will see most major NEMs offer higher speeds in their top-of-rack and end-of-row switches, and major server manufacturers offer 40GE interfaces in their high-performance servers. Development will be largely fueled by the availability of low-cost QSFP+ interfaces. Look for 100Gbsp ports on new offerings for links between core switches. Testing traffic and application delivery at 40/100Gbps speeds (over various distances) will be required to ensure new hardware implementations can meet scalability and quality of service (QoS) requirements.
Converged Fibre Channel and Ethernet Networks: The widespread use of low-cost 10Gbps Ethernet networking, coupled with new data center bridging (DCB) and Fibre Channel over Ethernet (FCoE) technologies, is finally making LAN/SAN convergence and its economic benefits a reality. Thus far, only Brocade, Cisco, HP, and Mellanox have announced FCoE support on their data center switches. In 2012, we expect to see many additional switch vendors jumping on this trend with FCoE offerings of their own. Conformance and performance benchmark testing will play a significant role in differentiating switch equipment based on overall scalability, traffic prioritization, low latency, and storage I/O performance.
Defending the Network: Zombies – compromised computers ready to act as robot attack systems – are ticking time bombs throughout the Internet. For example, the recent attacks on the WikiLeaks servers in Sweden demonstrate network vulnerability. The latest unified threat management (UTM) devices include multiple security mechanisms: firewalls, intrusion detection and prevention systems (IDS/IPS), anti-virus software, anti-spam and URL filters, and VPN gateways. Ixia predicts expanding distributed denial of service (DDoS) attacks will cause NEMs, service providers, and enterprises to validate that their network security is air-tight, up to date, and doesn’t impact network performance.
In 2012, Ixia predicts that cloud providers will start to compete on more than price, highlighting reliability, security, and responsiveness. To do this they will need to test their overall compute, storage, and network scalability. Cloud providers need to ensure their infrastructure is ready to offer high availability for all customers with different QoS levels for different tiers of service. Enterprise customers are also looking for ways to validate that their cloud providers are meeting service level agreements (SLAs) and shortening schedules to deploy applications in the cloud. Only by testing all aspects of cloud data-centers can one expose bottlenecks and optimize cloud infrastructures. Uncovering sources of performance degradation include:
- testing data center storage I/O in converged LAN/SAN environments
- access and aggregation switching tiers at 10/40GE
- core switching tiers at 100GE (data-center interconnect)
- virtualization layers with application workloads
- security effectiveness and accuracy
The consumers of cloud services will also need test solutions that can advise how much and where compute resources are needed to deliver adequate user quality of experience (QoE).
IPv4/IPv6 Co-existence: On February 1, 2011, the Internet Assigned Numbers Authority (IANA) allocated the last freely-available block of IPv4 addresses, pushing IPv6 addresses to the forefront. Service providers and enterprise are under the gun to prepare their networks for the influx of IPv6 traffic. Two major catalysts for IPv6 implementation are the large number of government-driven policy initiatives (US, Australia, Czech Republic, Germany, and many others) mandating IPv6-ready hardware and software deployment across public agencies, and Organization for Economic Co-operation and Development (OECD) countries – such as the Netherlands providing financial incentives for organizations to accelerate the IPv6 deployment. Service provider investment in upgrading access networks to support both IPv4 and IPv6 will continue through 2012. In the latter half of 2012 we also expect to see many large enterprises rolling out IPv6 on corporate networks. To ensure this evolution is transparent to networks users, NEMs, service providers, and enterprise IT will engage in both public and private tests that demonstrate equipment readiness.
5. Long Term Evolution, Mobile Backhaul, and the Evolved Packet Core
Long Term Evolution (LTE): By the end of 2011 there will be more than 30 commercial LTE deployments and many more trials ongoing world-wide. 2012 will see a doubling of commercial LTE networks, with North America and Asia leading the way in early deployments. As smart phone adoption rates increase and the use of media-rich applications expands, mobile operators will see continued capacity challenges. 2012 will see operators use multi-pronged approaches to solving capacity issues including:
- deployment of more spectrum-efficient technology
- increased data offload using Wi-Fi and small cells
- improved network traffic management
- new business models and charging plans
With these approaches, operators hope to not only increase raw capacity, but to lower the delivery cost per bit. Operators are spending billions to make their network more efficient, and prudent operators will thoroughly validate their networks in order to deliver on these objectives. The realistic simulation of millions of clients using media-rich applications will be a key driver for performance and capacity assurance. The very first implementations of voice on LTE networks using VoLTE will begin to occur in 2012, but don’t expect wide deployment until 2013 or beyond. 2012 will see mobile data networks become a more fertile ground for security attacks, causing wireless security testing needs to also ramp up.
Evolved Packet Core (EPC): The EPC is the aggregation point for all traffic originating from multiple wireless access types, including LTE and different variants of 3G technology. In 2012, “scalability” will be the mantra for new EPCs. These core networks must handle massive amounts of converged voice, video, and data traffic on a single IP-based network. The network and its component devices must prove their scaling capabilities in multiple dimensions. In particular, control plane scalability will be a major concern for NEMs and operators in 2012. Poor performance and faulty deployment plans can have severe consequences. History serves as evidence that subscriber dissatisfaction from a sluggish network or service outages is a real threat. The complexities of performance and how to properly manage network traffic are far too great for guess work. In 2012 and beyond, successful NEMs and operators must give due diligence to these critical issues and seek validation from test companies that are experts in this space.
Mobile Backhaul: Driven by bandwidth-hogging multimedia and mobile data, mobile operators are actively transforming their legacy TDM backhaul networks to a cost-effective IP-over-Ethernet paradigm. Clock synchronization is no longer a “barrier” to IP/Ethernet backhaul. The functionality and inter-vendor interoperability of IEEE 1588v2 precision time protocol has been proven in multiple public industry tests over the past 2 years, and 58% of service providers plan to deploy it by 2013 (source: Infonetics). The last hurdle for service providers is benchmarking the performance of boundary and transparent clock implementations, at scale, in the context of real-world traffic delivery. The onus will be on NEMs to prove the performance of their backhaul switches with tangible, repeatable test results. Service providers will also engage in pre-deployment testing to determine how to optimize network configurations to accommodate network growth and SLAs.
MPLS-TP: In 2012, the industry will turn to MPLS-TP performance testing to validate critical measurements such as scalability and automatic protection switchover. Public industry tests will also focus on MPLS-TP features that equip service providers with more advanced network management. Ixia expects to see very few service providers deploying MPLS-TP on their networks in 2012. In our opinion, widespread deployment is still at least 18 months away because only a handful of vendors have participated in public interoperability events – indicating an immaturity of many vendor implementations. Furthermore, proving MPLS-TP as a viable technology is only the first milestone toward widespread deployment. Service providers want evidence that MPLS-TP delivers service at scale with guaranteed QoS and “five 9’s” reliability.
Rich Media: A perfect storm is developing for network operators. Smartphone users expect information and entertainment 24 hours a day, in full living color. Wireless data usage will continue along its anticipated exponential growth curve, and large amounts of inexpensive bandwidth are no longer available. Enterprises will continue to move to the cloud, and critical applications will depend on guaranteed network access and performance.
We predict that network operators will need to compete and live up to their reliability commitments. They will need to maintain customers by ensuring that all types of customer service levels meet expectations and contractual requirements. Pre-testing network upgrades and advances prior to initial deployment is crucial to insure readiness for anticipated customers’ usage. This type of testing will involve real-world subscriber modeling that simulates a large quantity of mobile, home, and enterprise application usage – web, email, streaming video, VoIP – in typical and unusual scenarios.
