Abstract

The present invention enables a game server to provide hosting services by connecting the game server device to a peer group, notifying at least one member of the peer group of the availability of the server device, and enabling the server device to accept and respond directly to searches for the hosting services, which are directed at the peer group by one or more gaming client devices. Discovery of peer group gaming content as well as updating such content are also provided by the present invention. The present invention further enables both peer group protocol supported and non-supported devices to interact with and provide the services provided by a peer group.

5. The method of claim 1, when said joining to said peer group is made by a game server computing device that has no support for a protocol of the peer group, the method further comprising:

utilizing a gateway computing device to locate the peer group; and

receiving information from the gateway computing device, by the protocol unsupported game server computing device, regarding the location of one or more member game server nodes of the peer group, said one or more member game server nodes of the peer group being usable, by the protocol unsupported game server computing device, as a proxy node number of the peer group.

6. The method of claim 1, when said connection to said peer group is made by a game server computing device that supports a protocol of the peer group, the method further comprising utilizing said protocol to directly communicate with member game server nodes of the peer group to become a member game server of the peer group.

7. A computing system having a processor, a memory and an operating environment, the computing system operable to execute the method of claim 1.

8. A computer storage medium having computer executable instructions for performing the method of claim 1.

9. A method in a peer-to-peer gaming network computing environment for discovering downloadable content files known to members of a content peer group and of interest to a game client computing device, the method comprising the steps of:

the game client computing device joining the peer-to-peer gaming network;

automatically registering game client computing device for content updates upon joining the peer-to-peer gaming network; and

upon registering to the peer-to-peer gaming network, automatically receiving at the joined game client computing device, without a request therefrom, an index of downloadable content files, wherein the index is pushed from an authorized content contributor and is indirectly propagated via one or more of the members of a content peer group, wherein propagation comprises;

(a) receiving a copy of the index from the authorized content contributor at a first node of the peer-to-peer gaming network;

(b) receiving the copy of the index from the first node, via intercommunication between nodes joined to the peer-to-peer gaming network, at a second node of the peer-to-peer gaming network, wherein the second node represents a topologically proximate node to the joined game client computing device, and wherein the joined nodes employ a protocol of the peer-to-peer gaming network to identify the topologically proximate node to the joined game client computing device; and

(c) communicating the copy of the index from the second node to the joined game client computing device,

wherein said index of downloadable content files includes a reference to and location of downloadable content files residing on one or more content file repositories.

10. The method of claim 9, further comprising:

first requesting, by the game client computing device, certification to join the content peer group; and

second conforming to acceptable load balancing criteria for the content peer group.

11. The method of claim 10, further comprising receiving the certification and connection information to enable access to the content peer group.

12. The method of claim 9, when the game client computing device has no support for the protocol of the content peer group, the method further comprising:

utilizing, by the game client computing device, a gateway computing device to locate the content peer group; and

receiving information from the gateway computing device, by the game client computing device, regarding the location of one or more member nodes of the content peer group, said one or more member nodes of the peer group being usable, by the game client computing device, as a proxy node member of the content peer group.

13. The method of claim 9, when the game client computing device supports a protocol of the content peer group, the method further comprising directly communicating with member nodes of the content peer group and becoming a member of the content peer group.
