Abstract

Server capacity is increased on a network computer system. A total number of peers that an individual client will communicate with directly is determined. Then, a total number of clients handled by a server interconnected to the individual client is reduced by the determined total number or peers.

Claims

1. A method of increasing server capacity on a network computer system, comprising the steps of:

determining a total number of destination addresses that an individual client will directly communicate with so as to provide a peer address total;

assigning a plurality of destination addresses peer addresses with which the individual client communicates directly or server addresses corresponding to destination addresses handled by a server interconnected to the individual client on the network such that destination addresses are assigned as peer addresses until the peer address total is reached to thereby reduce a total number of destination addresses handled by the server by up to the peer address total;

wherein any destination addresses in excess of the peer address total are assigned as server addresses; and

communicating utilizing the peer addresses.

2. The method of claim 1, wherein said total number of destination addresses is set by said individual client.

3. The method of claim 1, where in said total number of destination addresses is set by a bandwidth management algorithm.

4. The method of claim 1, wherein addresses assigned as server addresses are known to said server and said individual client is not required to inform said server of an identity of said addresses.

5. The method of claim 1, wherein said server knows said peer address total and limits a number of unsolicited destination addresses provided to a destination of said individual client.

6. The method of claim 1, wherein said server can minimize latency by selecting said peer address total.

7. The method of claim 1, wherein at least one of said peer addresses comprises a multicast address-space.

8. The method of claim 1, wherein said client performs any encryption or data format translation to enable communication to said peer addresses.

9. The method of claim 8, wherein said server provides necessary encryption keys or other data format information to enable communication to said peer addresses supplied by said server.

13. The system of claim 1, wherein addresses assigned as server addresses are known to said server and said individual client is not required to inform said server of an identity of said addresses.

10. A system for increasing server capacity on a computer network, comprising:

means for determining a total number of destination addresses that an individual client will directly communicate with so as to provide a peer address total;

means for assigning a plurality of destination addresses as peer addresses with which the individual client communicates directly or server addresses corresponding to destination addresses handled by a server interconnected to the individual client on the network such that destination addresses are assigned as peer addresses until the peer address total is reached to thereby reduce a total number of destination addresses handled by the server by up to the peer address total;

wherein any destination addresses in excess of the peer address total are assigned as server addresses; and

means for communicating utilizing the peer addresses.

11. The system of claim 10, wherein said total number of destination addresses is set by said individual client.

12. The system of claim 10, wherein said total number of destination addresses is set by a bandwidth management algorithm.

14. The system of claim 10, wherein said server knows said peer address total and limits a number of unsolicited destination addresses provided to a destination of said individual client.

15. The system of claim 10, wherein said server can minimize latency by selecting said peer address total.

16. The system of claim 10, wherein at least one of said peer addresses comprises a multicast address space.

17. The system of claim 10, wherein said client performs any encryption or data format translation to enable communication to said peer addresses.

18. The system of claim 17, wherein said server provides necessary encryption keys on other data format information to enable communication to said peer addresses supplied by said server.

19. A computer program product recorded on computer readable medium for increasing server capacity on a computer network, comprising:

computer readable means for determining a total number of destination addresses that an individual client will directly communicate with so as to provide a peer address total;

computer readable means for assigning a plurality of destination addresses as peer addresses with which the individual client communicates directly or server addresses corresponding to destination addresses handled by a server interconnected to the individual client on the network such that destination addresses are assigned as peer addresses until the peer address total is reached to thereby reduce a total number of destination addresses handled by the server by up to the peer address total;

wherein any destination addresses in excess of the peer address total are assigned as server addresses; and

computer readable means for communicating utilizing the peer addresses.
