Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
93 words
A fault tolerant system for increasing traffic uniformity of a network system comprising a plurality of interconnected processors having first and second multistage networks coupling said processors to a plurality of nodes, wherein one of said first and second networks serves as a backup network for the other network said first and second multistage networks connected in parallel to transfer data in the same direction as the other between said processors and said nodes, said first multistage network distributed in an omega configuration and said second network distributed in a reverse omega configuration.
Claim 2
Dependent Claim
93 words
A fault tolerant system for increasing traffic uniformity of a network system comprising a plurality of interconnected processors having first and second multistage networks coupling said processors to a plurality of nodes, wherein one of said first and second networks serves as a backup network for the other network said first and second multistage networks connected in parallel to transfer data in the same direction as the other between said processors and said nodes, said first multistage network distributed in an omega configuration and said second network distributed in a reverse omega configuration.
Claim 3
Independent Claim
102 words
A method for providing a fault tolerant system for increasing traffic uniformity of a network system comprising a plurality of interconnected processors and a plurality of nodes comprising the steps of: a) arranging a first multistage network into an omega configuration; b) arranging a second multistage network into a reverse omega configuration and wherein one of said first and second multistage networks serves as a backup network for the other network; and c) connecting the omega equivalent configuration and the reverse omega equivalent configuration in parallel to transfer data in the same direction as the other between said processors and said nodes.
