Abstract： |
This invention relates to a test method for P2P data message based on character codes characterizing in carrying out relativity research to large quantities of P2P applied data packets and protocol analysis of the applied layer to pick up various P2P applied message character code samples and determine them the related P2P character codes, then filtering the applied layer content to each IP packet passing through the gateway device based on the character codes to confirm said IP packet is a P2P one, then the test result is added to the P2P database to be provided to the hardware. This invention is also suitable for IPv4 and IPv6 networks and analyzes the data messages of any communication protocols. |
