A content location method and routing device

Abstract

The embodiment of the invention discloses a content location method and a routing device. The method includes: storing content and / or content location information locally at the routing node, wherein the content location information includes a correspondence between the ID of the content and the address information of the next-hop routing node, and in the next-hop routing node The content storage address information of the content is stored; the routing node receives the content acquisition request, and locates the content requested by the content acquisition request according to the content and / or content location information stored in the routing node. The application of the present invention can improve the efficiency of content positioning.

Description

technical field [0001] The invention relates to the technical field of data services, in particular to a content location method and routing equipment. Background technique [0002] In recent years, content services have become the mainstream of Internet services, and content services generally include Internet TV, IPTV, mobile TV, file download, web browsing, and Web2.0. [0003] For content-based services, the process of users requesting content and obtaining content can be abstracted as figure 1 process shown. [0004] figure 1 It is a flowchart of a user requesting content and obtaining content in an existing content business. [0005] Such as figure 1 As shown, the process includes the following steps: [0006] Step 101: Receive a user's content request. [0007] Step 102: A plurality of nodes that store the location information of the content and have a content location function cooperate with each other to find the address of the node that stores the content req...

AI Technical Summary

Problems solved by technology

Existing methods are difficult to meet this efficiency requirement, especially when the amount of network content is gradually increasing, this method will become more and more difficult to meet the requirements of user access delay

Even in some non-delay-sensitive content services, excessive content positioning delay will reduce user satisfaction

[0035] In addition to the problem of low efficiency, the existing DHT-based content location method also has the problem of an excessively large number of interactive messages: the current DHT-based content location method usually needs to forward query messages multiple times between nodes to complete the content location. Positioning, when a large number of users request query content, there will be a large number of query messages in the network, and the forwarding of these large query messages will not only consume a large amount of network bandwidth resources, but also increase the computational overhead of node query and forwarding
