Routing Matrix with a TX Matrix Plus Router System Architecture

A routing matrix with a TX Matrix Plus router and up to four T1600 routers has two main architectural components, the control plane and the forwarding plane:

• The control plane in the routing matrix is formed by the connection of the TXP-CIPs in the TX Matrix Plus router and LCC-CBs in the T1600 routers, and the Routing Engines.
• The forwarding plane in the routing matrix is formed by the switch fabric—TXP-F13 SIBs and TXP-F2S SIBs in the TX Matrix Plus router and the TXP-T1600 SIBs and Packet Forwarding Engines in the T1600 Router.

The Routing Engines and the Packet Forwarding Engines perform their primary tasks independently. This arrangement streamlines routing control and forwarding and runs Internet-scale backbone networks at high speeds. Figure 1 shows the relationship between the Routing Engines and the Packet Forwarding Engines.
