Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
A communication network comprising a plurality of hosts including a source host and a destination host between which packets are to be transmitted, a wide area network over which said packets can be transmitted between said hosts using a best effort scheme, a guaranteed bandwidth network over which packets can be transmitted between said hosts at a continuous bandwidth and with assured quality of service, and an access point serving said source and destination hosts, each of said access points being a switching point where packets can either continue traveling over said wide area network or enter said guaranteed bandwidth network and comprising a first router for connecting said access point to said wide area network, a second router for connecting said access point to said guaranteed bandwidth network, an access server connected to communicate with one of said hosts, each of said first and second routers including a routing table, and server means for modifying said routing tables to determine whether said hosts between which packets are to be transmitted are to communicate over either a particular one or both of said wide area network and said guaranteed bandwidth network.
Claim 2
Dependent Claim
191 words
A communication network comprising a plurality of hosts including a source host and a destination host between which packets are to be transmitted, a wide area network over which said packets can be transmitted between said hosts using a best effort scheme, a guaranteed bandwidth network over which packets can be transmitted between said hosts at a continuous bandwidth and with assured quality of service, and an access point serving said source and destination hosts, each of said access points being a switching point where packets can either continue traveling over said wide area network or enter said guaranteed bandwidth network and comprising a first router for connecting said access point to said wide area network, a second router for connecting said access point to said guaranteed bandwidth network, an access server connected to communicate with one of said hosts, each of said first and second routers including a routing table, and server means for modifying said routing tables to determine whether said hosts between which packets are to be transmitted are to communicate over either a particular one or both of said wide area network and said guaranteed bandwidth network.
Claim 3
Dependent Claim
34 words
A communication network in accordance with claim 1 wherein said access point includes a bus to which each of said first router, said second router, said access server, and said server means are connected.
Claim 4
Dependent Claim
53 words
A communication network in accordance with claim 1 wherein said server means is connected between said access server and both of said first and second routers and all packets to be transmitted from a host are examined by said server means as they pass from said access server to one of said routers.
Claim 5
Dependent Claim
47 words
A communication network in accordance with claim 1 wherein said routing table utilizes the address of the source host, the address of the destination host, and an application port number of the source host to determine the communication of the packets between said source and destination hosts.
Claim 6
Dependent Claim
154 words
A communication network comprising a source host and a destination host, a wide area network and a guaranteed bandwidth network on which packets are communicated between said source and said destination hosts, a first router in communication with said guaranteed bandwidth network, a second router in communication with said wide area network, and an access server in communication with said first and second routers, said access server having a routing table which causes particular packets containing the destination address of said destination host and a particular application port number specifying a first application executing on said source host which originates said particular packets to be routed to said first router for transmission to said destination host via said guaranteed bandwidth network and which causes said packets other than said particular packets and containing said destination address to be routed to said second router for transmission to said destination host via said wide area network.
Claim 7
Dependent Claim
154 words
A communication network comprising a source host and a destination host, a wide area network and a guaranteed bandwidth network on which packets are communicated between said source and said destination hosts, a first router in communication with said guaranteed bandwidth network, a second router in communication with said wide area network, and an access server in communication with said first and second routers, said access server having a routing table which causes particular packets containing the destination address of said destination host and a particular application port number specifying a first application executing on said source host which originates said particular packets to be routed to said first router for transmission to said destination host via said guaranteed bandwidth network and which causes said packets other than said particular packets and containing said destination address to be routed to said second router for transmission to said destination host via said wide area network.
