Figure 5: A Full-duplex Interconnect
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.

Figure 6: A Matrix Interconnect
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
