Matrix.

This type of interconnect is typically used for chassis-based systems and higher-end fixed systems. In this

configuration, switching components are one hop away from the central processor that controls all the switches. Here, a

switching fabric (BCM5670 or 5671) serves as a backplane to multiple BCM5690s that are connected to it. For resiliency, a

matrix-based system can be configured with a redundant central processor, with switching chips interconnected to both

processors in a full-mesh configuration. This interconnect approach adds reliability to GE systems.

Daisy Chain.

In a daisy chain configuration, switches are interconnected to one another in a series. This modular

configuration is highly scalable, as there is virtually no limit to the number of incremental ports and central management CPU
