Patent abstract

Global ports are supported in multi-switch systems having arbitrary topologies. In some implementations, global ports are implemented in a manner which makes the switch system robust in the face of link failure. In specific Ethernet implementations, global ports enable flooding, learning, forwarding, and link aggregation across the switch system.
