Synchronization and recovery of peers in a peer to peer environment

A computer readable medium containing computer executable instructions for performing a method for use in a computer system, operating in a peer-to-peer environment having a host peer and at least one non-host peer, and for ordering operation requests of the peers, the operation requests being one of a list of recognized operations which may be requested, the method comprising:

• receiving, by the host peer, at least one operation request from the provided list;
• and
• assigning, by the host peer, a unique version number to the at least one operation request.

A computer system having a processor, a memory, and an operating environment, the computer system operable to execute a method within a peer-to-peer environment having a host peer and at least one non-host peer for ordering operation requests of the peers, the operation requests being one of a list of recognized operations which may be requested, the executable method comprising:

• receiving, by the host peer, at least one operation request from the provided list;
• and
• assigning, by the host peer, a unique version number to the at least one operation request

A method for use in a computer system, operating in a peer-to-peer environment having a host peer and at least one non-host peer, and for requesting operations of the host peer, the operations being one of a list of recognized operations which may be requested, comprising:

• sending, by the non-host peer, at least one operation request from the provided list to the host peer;
• and
• receiving, by the non-host peer, an operation order and an assigned unique version number associated with the operation request.

A computer readable medium having computer executable instructions for performing a method for use in a computer system operating in a peer-to-peer environment having a current host peer and at least one non-host peer, and for selecting a new host peer, the method comprising:

• providing each peer with an assigned indicia indicative of the order in which the peer first joined the peer-to-peer environment;
• determining whether the current host peer has terminated participation in the peer-to-peer environment, and if so;
• determining, by each remaining peer, if said peer has the lowest indicia indicating said peer joined the peer-to-peer environment prior to any remaining peers, and if so, sending, by said peer to each remaining peer, a message indicating that said peer is the new host peer.
