The following figure shows the 44-port GbE Large Module.
Figure 23: 44-port GbE Large Module
This module is oversubscribed and provides a 4:1 blocking ratio. The total available bandwidth
at all of the ports (44 Gbps) is four times the available routing bandwidth.
There are three groups on the module: one group has 12 ports, and two groups have 16 ports
each. For Layer 2 switching within each group, packets can be switched at full bandwidth.
However, for Layer 2 switching between groups and for all packets that are routed (Layer 3),
all external ports must share a limited number of links on the module. There are three links
available within the group of 12 ports, and there are four links available within each group of
16 ports. There is, therefore, a 12:3 (4:1) or 16:4 (4:1) contention for the internal links.
