• Virtual Switch Redundancy Protocol
(VSRP): Supports sub-second fault
detection and fail-over for mesh topologies
in which redundant switches provide
back-up operation for one another

• Rapid Spanning Tree Protocol Based
on IEEE 802.1w: Dramatically improves
the spanning tree convergence time to sub-
second by automatically renegotiating port
roles in case of a link failure without relying
on timers

topologies by identifying ports that request
a multicast stream and forwarding the
stream only on these ports. This dramatically
improves the performance of multicast
applications, allowing for many more
streams to be transiting the network.
