System of high availability synchronous bandwidth allocation over FDDI

摘要

A system of high availablity synchronous bandwidth allocation comprising an FDDI segment to which are connected a first device for allocating synchronous bandwidth over the FDDI segment to any requesting device, and at least a second device for requesting synchronous bandwidth over the FDDI segment. The first device and a third device also connected to said FDDI segment, are capable of a exchanging information regarding the allocation of synchronous bandwidth to at least the second device, the third device can take over for the first device as synchronous bandwidth allocator, if the first device fails.
