White Paper Abstract:
Over the past decade, IP/MPLS has been the packet-switching technology offering service providers the necessary flexibility and aggregation capabilities to reliably and efficiently transport user traffic. IP/MPLS has enabled packetized traffic convergence from all data sources—including mobile and fixed station voice, TV programming, and video distribution, in addition to “traditional” packet-based business and residential data services. Payloads are thus represented by variable rate and variable intensity packet streams, which are groomed into fixed rate time division multiplexing (TDM) containers for transportation—a mismatch that raises questions about the efficiency of core utilization and the potential for new opportunities to simplify and streamline operations.
This paper examines the options available in service provider core networks through the perspective of the demands that changing service types and traffic patterns place on such networks. Readers learn why there is a need for increased flexibility in the network core, and why packet-switched cores represent the most efficient way to meet service delivery goals. Juniper Networks® core routing solutions provide the intelligence, flexibility, and efficiency required in next-generation network cores, and are uniquely optimized to help service providers meet the demands of changing traffic patterns.
With higher capacity interfaces such as 40GbE and 100GbE, and 2:1 oversubscription on 100 Gbps/slot interfaces, the flexibility and operational benefits of a packet-switched core based on Juniper technology will lower total cost of ownership for many years to come.
