Abstract
Abstract The system and method of this invention enables a plurality of nodes (A,...., E) in a network to communicate with each other through a communication protocol that will be understood by any node that is a party to the present conversation. Each node may utilize a different version level of a distributed services program that allows nodes to communicate in a distributed environment. At the time a connection is initiated with another node in the network, the highest version level that both nodes have in common is determined. This common version level is then used as the protocol for any further communication.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
A system for communicating between a first node and a second node, said system comprising: a first set of communication conventions acceptable to said first node; a second set of communication conventions acceptable to said second node; means for determining at least one communication convention common to the first set and the second set; and means for communicating between the first and second node using the common communication convention.
Claim 2
Independent Claim
69 words
A system for communicating between a first node and a second node, said system comprising: a first set of communication conventions acceptable to said first node; a second set of communication conventions acceptable to said second node; means for determining at least one communication convention common to the first set and the second set; and means for communicating between the first and second node using the common communication convention.
Claim 3
Dependent Claim
37 words
The system of Claim 1 wherein the first set of communication conventions is represented by a first range of version levels, and the second set of communication conventions is represented by a second range of version levels.
Claim 4
Dependent Claim
28 words
The system of Claim 2 wherein the means for determining at least one common communication convention determines a highest version level common to the first and second set.
Claim 5
Independent Claim
71 words
A method for communicating between a first node having a first set of communication conventions acceptable to said first node and a second node having a second set of communication conventions acceptable to said second node, said method comprising: determining at least one of said communication conventions common to the first node and the second node; and communicating between the first node and the second node using said common communication convention.
Claim 6
Independent Claim
71 words
A method for communicating between a first node having a first set of communication conventions acceptable to said first node and a second node having a second set of communication conventions acceptable to said second node, said method comprising: determining at least one of said communication conventions common to the first node and the second node; and communicating between the first node and the second node using said common communication convention.
Claim 7
Dependent Claim
92 words
The method according to claim 4, comprising the steps of; initiating a connection from the first node to the second node; sending from the first node to the second node a first description of the first set; determining at the second node if at least one element is common to the first set and the second set; returning to the first node from the second node a description of said at least one element; and communicating between the first node and the second node using the communication convention of said returned element.
Claim 8
Dependent Claim
81 words
The method according to claim 4, comprising the steps of; initiating a connection from the first node to the second node; sending from the first node to the second node a first description of the first set; determining at the second node if at least one element is common to the first set and the second set; and indicating to the first node from the second node that the intersection is free of elements common to said first and second sets.
Claim 9
Independent Claim
94 words
A method for communicating between a first node having a first set of communication conventions acceptable to said first node to request a plurality of operations to be performed by a second node having a second set of communication conventions acceptable to said second node, said method comprising; determining at least one of said communication conventions common to said first and said second node for at least one of said operations; and communicating between said first node and said second node using said at least one communication convention during said at least one operation.
Claim 10
Independent Claim
94 words
A method for communicating between a first node having a first set of communication conventions acceptable to said first node to request a plurality of operations to be performed by a second node having a second set of communication conventions acceptable to said second node, said method comprising; determining at least one of said communication conventions common to said first and said second node for at least one of said operations; and communicating between said first node and said second node using said at least one communication convention during said at least one operation.
