Content delivery method, equipment and system based on MPTCP (Multi-Path Transmission Control Protocol)

Abstract

The embodiment of the invention discloses a content delivery method, equipment and system based on a MPTCP (Multi-Path Transmission Control Protocol). The method comprises the steps that: a NMS (Network Management System) acquires an IP (Internet Protocol) address of a first network node and an IP address of a second network node; the NMS determines a tunnel between the first network node and thesecond network node according to the IP address of the first network node and the address of the second network node, wherein information of tunnels configured according to an IP address of each network node managed by the NMS is pre-stored in the NMS; and the NMS sends information of a target tunnel to at least one of the first network node and the second network node, so that the first network node and the second network node establishes a connection on the target tunnel according to the information of the target tunnel, wherein the target tunnel is the tunnel between the first network nodeand the second network node. By adopting the content delivery method, equipment and system disclosed by the embodiment of invention, establishment efficiency of the tunnel connection can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a multi-path (Multi-path TCP, MPTCP)-based content transmission method, device, and system. Background technique [0002] Video transmission has much higher requirements on bandwidth and delay than the Web. In order to improve the user experience of watching videos and reduce the bandwidth pressure on the bearer network, content providers usually use Content Delivery Network (CDN) to deliver video transmission. In addition, if the client and server in the CDN network (users can watch video through the client, and the server is used to provide video to the client), tunneling technology can greatly improve the transmission efficiency of video data (for example, Multiprotocol Label Switching (Multiprotocol Label Switching) Tunnels in Label Switching (MPLS) can be dynamically created and deleted on demand), when both the server and the client have...

AI Technical Summary

Problems solved by technology

[0009] The problem with the prior art is that when the client and the server transmit based on the MPTCP technology, 3*4=12 trials and errors are required to confirm the connection between C1 and S1, the connection between C2 and S2, The connection between C3 and S3 is a connection established on a tunnel, that is, the establishment of a tunnel connection is less efficient
