A method for distributing file data includes: obtaining a first request message of a first client for downloading a first file, and determining an autonomous system (AS) where the first client is located; searching the AS for edge servers that support peer to peer (ES-Ps), and returning the address of at least one ES-P storing the first file to the first client; and sending the first file stored in the ES-P to the first client according to the client information returned by the ES-P. Related devices and systems are also provided. The present invention may speed up the file data distribution, reduce the restriction of the file data distribution due to fixed bandwidth of the ES, and enable P2P data streams to be converged into an AS, thus reducing the impact on backbone networks.

Method, device and system for distributing file data

A method for constructing a network topology is applied in a streaming delivery system. The streaming delivery system includes: a center server (CS-P), an edge server (ES-P), a request scheduling server (RRS-P), and a client. The disclosed embodiments utilizes the upload capabilities of the client to transmit a part of streaming data, thus consuming fewer center server resources. By constructing the network topology, the disclosed embodiments enable the client to obtain a part of streaming data from other clients, reduces the load capability requirements for the server, and ensures that a streaming delivery network may provide streaming live services with higher bandwidths and better quality.

Method for constructing network topology, and streaming delivery system

The present invention relates to a P2P network system. The P2P network system includes: multiple local overlay networks, each comprising multiple proxy service peers; a global overlay network composed of the proxy service peers of all local overlay networks. The proxy service peer is adapted to respond to the request of the requesting peer, query the local overlay network or global overlay network, and return the address information of the requested peer or the requested proxy service peer to the requesting peer. The present invention also relates to a proxy service peer applicable to the foregoing network system, and a method of peer interworking between P2P overlay networks based on the foregoing system. The present invention relieves the load of the proxy service peer, avoids blindness of the requesting peer in selecting the proxy service peer, and achieves load balance between proxy service peers.
