P2P (Peer-to-Peer) redirection mechanism based on cloud-edge combination technology

Abstract

The invention relates to a P2P (Peer-to-Peer) redirection mechanism based on a cloud-side combination technology, which comprises the following steps: a user sends a P2P service request message and transmits the P2P service request message to an ONU (Optical Network Unit), the ONU identifies the P2P service request through service and extracts data packet information of the request after receiving the P2P service request sent by the user, the data packet information comprises a file name, and the ONU compares the filename with a file information table maintained by the ONU, namely an ONU table, detects whether the filename exists in the ONU table and performs corresponding processing, and further judges whether the filename exists in an OLT table if the filename does not exist in the ONU table. According to the P2P redirection mechanism, a plurality of requests can be processed to serve as internal flow, the problem that the computing load of a center OLT of cloud computing is too heavy is solved, the P2P flow in a core network is effectively reduced, the bearing capacity of a PON for local P2P services is improved, and therefore the overall QoS and the bandwidth utilization rate are improved.

Description

technical field [0001] The invention belongs to the technical field of P2P service transmission, and in particular relates to a P2P redirection mechanism based on cloud-side combination technology. Background technique [0002] At present, P2P technology is widely used in file sharing, network video, Internet telephony and other fields. With the characteristics of distributed resource sharing and parallel transmission, it provides users with more resources, higher available bandwidth and better service quality. P2P applications have become one of the main applications of the Internet, and the P2P model has also become the first choice for many new services. The continuous emergence of new services, especially some immature services, makes the foundation of both the access network and the core network Facilities are under tremendous pressure. The centralized cloud can no longer meet the cloud resource requirements of large connections, low latency, and large bandwidth on the ...

AI Technical Summary

Problems solved by technology

However, the currently proposed solutions generally do not take into account the problems of excessive burden and high time delay due to the increase in the number of access networks. Therefore, the present invention provides a method that can solve the problem of heavy computing load of the central OLT of cloud computing, effectively reducing the P2P traffic in the core network to improve the carrying capacity of PON for local P2P services, P2P redirection mechanism based on cloud-side combination technology
