Method and apparatus for improving service quality of peer-to-peer superpose network as well as peer-to-peer node

Abstract

The invention discloses a method and a device for improving quality of service (QoS) of a peer-to-peer (P2P) overlay network, and a P2P node thereof, relating to P2P network technology and aiming to solve the poor QoS of the prior P2P overlay network. The method comprises the following steps: receiving a P2P message with priority information; acquiring the priority information from the P2P message; and conducting differential processing to the priority information. The embodiment of the invention is applicable in the P2P overlay network.

Description

technical field [0001] The present invention relates to a peer-to-peer (Peer-to-Peer, P2P) network technology, in particular to a method, device and peer-to-peer node for improving service quality of a peer-to-peer overlay network (Peer-to-Peer Overlay, P2P Overlay for short). Background technique [0002] An overlay network (Overlay Network) is a virtual network established on top of one or more existing lower-layer networks (eg, physical network or logical network) in order to realize certain specific functions. Although there are many physical links in the lower layer network of the Overlay network, since the nodes of the Overlay network can be regarded as being connected by virtual or logical links, and the virtual or logical links do not One-to-one correspondence with physical paths, so the virtuality of the Overlay network on the existing network can be used to implement functions that are difficult to implement on the underlying network, such as message routing or top...

Problems solved by technology

[0004] Although the P2P Overlay network can be used to build a layer of virtual P2P network on the basis of the existing Internet to realize the functions of the P2P network, but in the process of implementing the present invention, the inventor found that the P2P Overlay network lacks QoS mechanism, the P2P messages transmitted through the P2P Overlay network have the same priority, when peer nodes on the P2P Overlay network receive multiple P2P messages, the nodes process the received messages according to the first-in-first-out (FIFO) principle P2P message

Due to the lack of QoS mechanism in the P2P Overlay network, important or critical P2P messages may not be processed in time, and may be submerged in a large number of ordinary P2P messages. P2P messages are flooded and cannot be responded in time, which leads to changes in the topology of the P2P Overlay network. The P2P Overlay network cannot converge in time, which may cause network failures.

Or the P2P messages carrying emergency call services may be submerged in a large number of P2P messages carrying ordinary call services, which may reduce the QoS of emergency call services and fail to meet service requirements

[0005] With the continuous deepening and development of research on P2P networks, the business carried on the P2P network is also increasing, and the type and quantity of messages transmitted by the P2P Overlay network are also increasing. The lack of QoS mechanism guarantee will lead to The service quality of P2P Overlay network declines, thus affecting the development of P2P network
