Abstract
The present invention relates to a method for identifying P2P application connections, which includes: searching corresponding ports of intranet IPs according to the data package received; and identifying the connection of the data package to be P2P application connection when the counter value of the said port is the preset threshold and represents the number of all simultaneous online UDP connections to the port. When the counter value of the said port is not the preset threshold, and the connection of the data package is a new UDP connection, the counter value of the said port will be added by 1; when the UDP connection of the said port is disconnected, the counter value of the port will be deducted by 1. It is a primary object of the present invention to provide a method and a device for identifying P2P application connections based on the behavioral characteristics of UDP, which have improved the accuracy of P2P application identification.
