Control plane architecture for switch fabrics

摘要

In some embodiments, a system includes multiple access switches, a switch fabric having multiple switch fabric portions, and a control plane processor. Each switch fabric portion is coupled to at least one access switch by a cable from a first set of cables. Each switch fabric portion is configured to receive data from the at least one access switch via the cable from the first set of cables. The control plane processor is coupled to each switch fabric portion by a cable from a second set of cables. The control plane processor is configured to send control information to each access switch via a cable from the second set of cables, a switch fabric portion, and a cable from the first set of cables. The control plane processor is configured to determine control plane connections associated with each access switch and is configured to determine data plane connections associated with each access switch as a result of the control plane connections.
