Method and apparatus in a communication network for updating and maintaining record data

A communication network including a first and second servers connected via a common network, wherein said first server owns a record data associated with at least one process running for serving a client device using said communication network through said first server, said second server keeping a copy of said record data, an apparatus in said communication network comprising:

• means for performing a Hashing function over said record data to produce a first Hash value, wherein said hashing function comprises concatenating UDP port information and at least a portion of an IP address to produce a string record of A(e), squaring said string record of A(e) to produce a squared record of A(e), and truncating said squared record of A(e) to at least a predetermined record length;
• means for performing said Hashing function over said copy of said record data to produce a second Hash value;
• means for sending said first Hash value from said first server to said second server.
