Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
159 words
A system for network wide bandwidth allocation in a network made of at least one FDDI segment and at least one non-FDDI Segment, said system comprising: a server coupled to the FDDI segment and comprising a Quality of Service Requestor for requesting quality of service, a network bandwidth allocator (NRR) comprising a Quality of Service Allocator, coupled to the non-FDDI segment, for getting requests and setting answers from and to said Quality of Service Requestor, a synchronous bandwidth allocator (SBA) on said FDDI segment for allocating bandwidth on said FDDI segment, said system being characterized in that the system comprises: a third party requestor (3PR), with Inputs/Outputs for interfacing between said network bandwidth allocator (NRR) and said synchronous bandwidth allocator (SBA), and Inputs/Outputs for interfacing between said server and said synchronous bandwidth allocator (SBA), and means (C) in said network bandwidth allocator (NRR) having Input/Output for interfacing between said Quality of Service Allocator and said third party requestor (3PR).
Claim 2
Independent Claim
159 words
A system for network wide bandwidth allocation in a network made of at least one FDDI segment and at least one non-FDDI Segment, said system comprising: a server coupled to the FDDI segment and comprising a Quality of Service Requestor for requesting quality of service, a network bandwidth allocator (NRR) comprising a Quality of Service Allocator, coupled to the non-FDDI segment, for getting requests and setting answers from and to said Quality of Service Requestor, a synchronous bandwidth allocator (SBA) on said FDDI segment for allocating bandwidth on said FDDI segment, said system being characterized in that the system comprises: a third party requestor (3PR), with Inputs/Outputs for interfacing between said network bandwidth allocator (NRR) and said synchronous bandwidth allocator (SBA), and Inputs/Outputs for interfacing between said server and said synchronous bandwidth allocator (SBA), and means (C) in said network bandwidth allocator (NRR) having Input/Output for interfacing between said Quality of Service Allocator and said third party requestor (3PR).
Claim 3
Dependent Claim
142 words
In a network having at least one FDDI segment and at least one non-FDDI segment; a system for providing network wide bandwidth allocation comprising: a server coupled to the network comprising at least Quality of Service Requestor to request quality of service; a network bandwidth allocator (NRR) coupled to the non-FDDI Segment said network bandwidth allocator comprising a Quality of Service requestor for receiving requests from and returning answers to said Quality of Service requestor; a synchronous bandwidth allocator (SBA) on said FDDI segment for awarding bandwidth on the FDDI segment; and a third party requestor (3PR) coupled to the network; said third party requestor requesting from said synchronous bandwidth allocator bandwidth allocation in response to requests from said network bandwidth allocator and issuing a response to said network bandwidth allocator as a result of a response from the synchronous bandwidth allocator.
Claim 4
Dependent Claim
142 words
In a network having at least one FDDI segment and at least one non-FDDI segment; a system for providing network wide bandwidth allocation comprising: a server coupled to the network comprising at least Quality of Service Requestor to request quality of service; a network bandwidth allocator (NRR) coupled to the non-FDDI Segment said network bandwidth allocator comprising a Quality of Service requestor for receiving requests from and returning answers to said Quality of Service requestor; a synchronous bandwidth allocator (SBA) on said FDDI segment for awarding bandwidth on the FDDI segment; and a third party requestor (3PR) coupled to the network; said third party requestor requesting from said synchronous bandwidth allocator bandwidth allocation in response to requests from said network bandwidth allocator and issuing a response to said network bandwidth allocator as a result of a response from the synchronous bandwidth allocator.
Claim 5
Dependent Claim
14 words
The system of claim 2 further including a multi-media application running on the server.
Claim 6
Dependent Claim
27 words
The system of claim 3 further including a client station connected to the non-FDDI segment, said client station running an application for communicating with the multi-media application.
