The success and familiarity of MPLS in the core is driving service providers to deploy MPLS beyond the core network and into access, aggregation, and backhaul networks to support broadband, business, and mobility services. With active development in standards bodies, MPLS is also emerging as an industry standard to enable connection-oriented packet transport with MPLS-TP. Read more »
