Fast Sequenced Transport
From Network Dictionary Wiki
Fast Sequenced Transport (FST) is a connectionless, sequenced transport protocol that runs on top of the IP protocol. Source-Route Bridging (SRB) traffic is encapsulated inside of IP datagrams and is passed over a FST connection between two network devices (such as routers). FST speeds up data delivery, reduces overhead, and improves the response time of SRB traffic.
