Chapter 3: Routing Matrix with a TX Matrix Plus Router System Architecture Overview
from the source T1600 router, through the switch fabric on the TX Matrix Plus router, to
the target T1600 router. The switch fabric allows high-priority traffic from any Packet
Forwarding Engine to an egress Packet Forwarding Engine to be given preferential
treatment over low-priority traffic from any other Packet Forwarding Engine. The Packet
Forwarding Engine on the target T1600 router forwards the packet to the destination
PIC and interface.
Figure 34 on page 61 illustrates the switch fabric architecture.
