ABSTRACT:
A control backplane replaces the traditional shared bus with a dedicated communication channel using a high-speed protocol, such as Ethernet. The resulting system may conduct several concurrent control sessions with clients and devices associated with the network switch. Removing the shared bus from the control plane also improves the reliability of the new system, because it is no longer susceptible to a single point of failure.
