Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method for redirecting P2P services in a passive optical access network, which is applicable to existing mainstream P2P protocols and P2P protocols that may appear in the future, without modifying the P2P protocol. It can solve the problem of P2P topology mismatch

Embodiment Construction

[0033] The inventor has carefully studied various types of P2P protocols, and found that the difference between them is only the joining and exiting mechanism of the client system, the file indexing mechanism and the routing mechanism, etc., while the existing various P2P protocols include There are the interactive process of client system list query and response before the download of fragmented files, and the notification after the download of the assigned file is completed. Even though there are slight differences in the specific implementations in different P2P protocols, the essence is the same: the client Before the end system downloads a fragment file, it needs to receive the client system list returned by the server or other client systems in the P2P network. The client system list contains the information of the client system that provides the download of the fragment file; After the client system downloads a certain fragment file, it will send a file download completi...

Abstract

The invention provides a method for reorienting an end-to-end service in a passive optical access network. In the method, an OLT uses an internal client system of the passive optical access network to replace a client system list in a related P2P protocol message to allow the internal client system of the passive optical access network to have the priority for downloading fragmental files from other internal client systems of the passive optical access network, so a problem of mismatch of a P2P topology is solved, download flow of a public network is reduced, and the bandwidth resource of a core network is saved.

Description

technical field [0001] The invention relates to a passive optical access network, in particular to a method for point-to-point (P2P, Peer to Peer) service redirection in a passive optical access network. Background technique [0002] Driven by the strong demand for broadband services such as high-speed Internet access, video, and Ethernet private lines, the access network must be optical fiberized. Passive Optical Network (PON, Passive Optical Network) has become the mainstream technology of optical access network due to its advantages of high bandwidth, low cost, suitable for multicast service transmission, easy maintenance and high reliability. The PON system connects an optical line terminal (OLT, Optical Line Terminal) and an optical network unit (ONU, Optical Net Unit) through an optical distribution network (ODN, Optical Distribution Network), and its topology is in the form of point-to-multipoint. [0003] In recent years, P2P peer-to-peer services have become increa...
