Data Flow Through the M10i Router Packet Forwarding Engine

124
The integrated ASIC on the CFEB performs a route lookup for each packet and decides
3.
how to forward it.
a. If services are configured for the packet, the integrated ASIC reassembles the
packet and passes it to the services interface.
b. The services interface passes the packet to the CFEB, where the integrated ASIC
processes the packet, divides the packet into 64-byte cells, and distributes the
data cells throughout the memory buffer.
c. The integrated ASIC performs a second route lookup for each packet and decides
how to forward it.
The integrated ASIC notifies the outbound networking interface.
4.
The integrated ASIC reassembles data cells stored in shared memory into data packets
5.
as they are ready for transmission and passes them to the outbound networking
interface.
The outbound networking interface transmits the data packets.

Data flows through the M10i routers Packet Forwarding Engine in the sequence shown
in Figure 25 on page 124. Use of ASICs promotes efficient movement of data packets
through the system.
