Abstract To solve the problem raised by the allocation of synchronous bandwidth on a FDDI segment when this allocation is done by a centralized Allocator in an interconnected LAN domain, a Third Party Requestor receives from Quality of Service Allocator all information that it needs to ask for bandwidth reservation on the FDDI segment. Following the Station Management standard , the Third Party Requestor is able to act on behalf of the FDDI station that will submit synchronous traffic and ask for bandwidth allocation to a Synchronous Bandwidth Allocator. According to the Synchronous Bandwidth Allocator decision, the Third Party Requestor will then answer to the Quality of Service Allocator which will grant or deny the allocation over the whole path.
System for network wide bandwidth allocation in a network made of at least one FDDI segment, comprising: - a client running over said network an application with a server comprising a Quality of Service Requestor, - a network bandwidth allocator (NRR) comprising a Quality of Service Allocator getting requests and setting answers from and to said Quality of Service Requestor, - a synchronous bandwidth allocator (SBA) on said FDDI segment, said system being characterized in that it comprises: - a third party requestor (3PR), for interfacing between said network bandwidth allocator (NRR) and said synchronous bandwidth allocator (SBA), and between said server and said synchronous bandwidth allocator (SBA), - means in said network bandwidth allocator (NRR) for interfacing between said Quality of Service Allocator and said third party requestor (3PR).
