Problems solved by technology
[0003] In the prior art, because P2P traffic occupies a large amount of network bandwidth, Internet providers have taken restrictive measures for P2P traffic
In order not to affect normal use, many P2P application software encrypts the P2P traffic it transmits, making it difficult for Internet providers to identify and restrict encrypted P2P traffic
[0004] However, since the P2P traffic has been encrypted, it will be difficult for the CDN system to identify and process the encrypted P2P traffic, making it difficult to cache the P2P resources locally and distribute the encrypted data to the user according to the user's P2P resource acquisition request. Cached P2P resources

The invention provides a P2P (Peer to Peer) resource sharing method and device. The method comprises the steps of sending P2P protocol acknowledgement messages to corresponding client and server according to source node information and destination node information of a message when a protocol type of the message is not identified according to a message feature; determining that the message is a P2P resource request message if a P2P protocol response message is received; obtaining suspicious target P2P resources corresponding to the message according to access records of the client to the server, and caching the suspicious target P2P resources; sending a file list of the suspicious target P2P resources to the client; and sending the corresponding P2P resources to the client after the suspicious target P2P resource obtaining request is received. Through application of the method, the encrypted P2P traffic can be identified in a CDN (Content Delivery Network) system; the P2P resources can be locally stored according to the encrypted P2P traffic; and the cached P2P resources are distributed to a user according to the demand of the user.
Description
technical field [0001] The present application relates to the technical field of network communication, and in particular to a P2P (Peer to Peer, P2P for short) resource sharing method and device. Background technique [0002] The CDN (Content Delivery Network) system can realize local caching of P2P resources by adding a new layer of network architecture to the existing Internet, so that users in the CDN system can obtain the required P2P resources nearby , thereby improving the efficiency when users obtain P2P resources, and at the same time improving the congestion of the Internet network. [0003] In the prior art, because the P2P traffic occupies a large amount of network bandwidth, Internet providers take restrictive measures on the P2P traffic. In order not to affect normal use, many P2P applications encrypt the P2P traffic they transmit, making it difficult for Internet providers to identify and restrict encrypted P2P traffic. [0004] However, since the P2P traffi...
