The PTX5000 Packet Transport Router provides high-density 10GbE, 40GbE, and 100GbE interfaces for large networks and network applications, addressing the needs of Internet service providers and high-volume content providers. Occupying 36 rack units, the PTX5000 can be configured with up to eight FPCs, each capable of connecting two PICs that support a variety of network media types. The PTX Series architecture cleanly separates control operations from packet-forwarding operations, eliminating processing and traffic bottlenecks while enabling the router to deliver extreme performance for both IP and MPLS.
