[0049] In the first embodiment of the present invention, a method for detecting P2P traffic, such as figure 1 shown, including the following specific steps:
[0050] In step S101, the source host is monitored to obtain the number of destination hosts connected to the source host and the number of active sessions on the source host. When the source host accesses the destination host, it initiates a connection request to the destination host, and the destination host is a host that provides download resources.
[0051] Specifically, the acquisition process of the number of destination hosts connected to the source host is as follows:
[0052] Determine the number of destination hosts connected to the source host by counting the IP addresses of the destination hosts accessed by the source host;
[0053] Such as figure 2 As shown, the acquisition process of the number of active sessions on the source host is as follows:
[0054] S1. Determine the activity level of the session...

[0065] In the second embodiment of the present invention, a device for detecting P2P traffic, such as Figure 4 shown, including the following components:
[0066] The monitoring module 100 is used to monitor the source host to obtain the number of destination hosts connected to the source host and the number of active sessions on the source host; when the source host accesses the destination host, it initiates a connection request to the destination host, and the destination host provides download resources host.
[0067] The judging module 200 is configured to judge whether the source host has P2P features according to the number of destination hosts connected to the source host and the number of active sessions on the source host.
[0068] Specifically, when acquiring the number of destination hosts connected to the source host, the monitoring module 100 is specifically used to:
[0069] Determine the number of destination hosts connected to the source host by counting th...
