Abstract
Abstract A novel video server is taught which allows for additional output bandwidth from the server by using multiple physical network interfaces over a single IP subnetwork. This approach is particularly well suited for use with video servers that store and deliver multimedia bit streams by allowing all clients to share the same subnetwork with the server. In this manner, the bandwidth from each of the physical network interface can be combined as needed and assigned as needed in service to any plurality of destinations in the network, allowing all bandwidth to be available for use with one or more clients.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
91 words
A video server system comprising: a video server; an interface protocol subnetwork; a plurality of physical network interfaces coupled between said server and said interface protocol subnetwork; and one or more destination systems, each including a physical network interface coupled to said interface protocol subnetwork, wherein the bandwidth from each of said physical network interfaces coupled to said interface protocol subnetwork and associated with said server are combined as needed and assigned as needed in service to any one of said plurality of destination systems coupled to said interface protocol subnetwork.
Claim 2
Dependent Claim
91 words
A video server system comprising: a video server; an interface protocol subnetwork; a plurality of physical network interfaces coupled between said server and said interface protocol subnetwork; and one or more destination systems, each including a physical network interface coupled to said interface protocol subnetwork, wherein the bandwidth from each of said physical network interfaces coupled to said interface protocol subnetwork and associated with said server are combined as needed and assigned as needed in service to any one of said plurality of destination systems coupled to said interface protocol subnetwork.
Claim 3
Dependent Claim
30 words
A video server system as in claim 1 wherein said physical network interfaces include control for assigning load between said plurality of physical network interfaces associated with said video server.
Claim 4
Dependent Claim
56 words
A video server system as in claim 2 wherein said plurality of physical network interfaces associated with said video server are allocated to said destination systems on a session granularity, with each session including at least one attribute that specifies the maximum amount of bandwidth that is required for all data transmission corresponding to said session.
Claim 5
Dependent Claim
21 words
A video server system as in claim 1 wherein said plurality of physical network interfaces share a single assigned IP address.
Claim 6
Dependent Claim
40 words
A video server system as in claim 4 wherein a first control layer uses a single IP address and a second control layer allocates bandwidth requests with respect to said single IP address among said plurality of physical network interfaces.
Claim 7
Independent Claim
91 words
A method for operating a video server system comprising the steps of: coupling a plurality of physical network interfaces between a video server and an interface protocol subnetwork; coupling one or more destination systems, each utilizing a physical network interface coupled to said interface protocol subnetwork; and combining as needed and assigning as needed the bandwidth from each of said physical network interfaces coupled to said interface protocol subnetwork and associated with said server, in service to any one of said plurality of destination systems coupled to said interface protocol subnetwork.
Claim 8
Independent Claim
91 words
A method for operating a video server system comprising the steps of: coupling a plurality of physical network interfaces between a video server and an interface protocol subnetwork; coupling one or more destination systems, each utilizing a physical network interface coupled to said interface protocol subnetwork; and combining as needed and assigning as needed the bandwidth from each of said physical network interfaces coupled to said interface protocol subnetwork and associated with said server, in service to any one of said plurality of destination systems coupled to said interface protocol subnetwork.
Claim 9
Dependent Claim
30 words
A method as in claim 6 wherein said step of coupling a physical network interface includes assigning load between said plurality of physical network interfaces associated with said video server.
Claim 10
Dependent Claim
58 words
A method as in claim 7 which further comprises the step of allocating said plurality of physical network interfaces associated with said video server to said destination systems on a session granularity, with each session including at least one attribute that specifies the maximum amount of bandwidth that is required for all data transmission corresponding to said session.
Claim 11
Dependent Claim
19 words
A method as in claim 6 wherein said plurality of physical network interfaces share a single assigned IP address.
Claim 12
Dependent Claim
38 words
A method as in claim 9 wherein a first control layer uses a single IP address and a second control layer allocates bandwidth requests with respect to said single IP address among said plurality of physical network interfaces.
