Network match maker matching requesters based on communication attribute between the requesters

A network match making method and system matches an additional computer executing an instance of a client computer program with one or more other computers executing instances of client computer programs. The computers are linked by one or more communication links. A match maker computer program receives a request from the instance executing on the additional computer to match with an instance executing on another computer. A measurement request is sent to the instance executing on the additional computer. Communication attributes between the additional computer and each existing computer are measured and an existing computer is selected as a match for the additional computer if one of the communication attributes exceeds a minimum performance requirement. Existing computers can be further selected based on further attributes. If none of the communication attributes meets the minimum performance requirement, a match maker program waits for a further request. The communication attributes measured can relate to at least one parameter such as latency, packet lost rate, and bandwidth.
