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 30 on page 56 shows the
relationship between the Routing Engines and the Packet Forwarding Engines.
