Embodiment Construction

[0060] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0061] Such as figure 1 As shown, the present invention provides a content-based Internet cache response system, including: a connection establishment unit 1, a plurality of cache transmission units 2, at least one message receiving unit 4, a unified signaling interaction protocol 3 and message processing Unit 5;

[0062] Establishing a connection unit 1 is used to automatically select any one of a plurality of cache transmission units 2, establish a connection between the cache transmission unit 2 and the cache, and complete data transmission;

[0063] The cache transmission unit 2 is used to transmit the content identifier-based cache content sent in the Internet, and generate a cache update message based on the content identifier according to the unified signaling interaction protocol, and...

Abstract

The invention discloses an Internet cache response system based on content identification. The Internet cache response system comprises a plurality of cache transmitting units, at least one message receiving unit and a unified signaling interaction protocol. The cache transmitting units are used for transmitting cache content based on the content identification and sent by the Internet, generating a cache updating message based on the content identification according to the unified signaling interaction protocol and transmitting the updating message to the outside, the message receiving unit is used for processing the cache response according to the updating information after receiving the updating message sent by the cache transmitting units, and the unified signaling interaction protocol is used for data communication between the cache transmitting units and the message receiving unit. The invention further discloses an Internet cache response method based on the content identification.

Description

technical field [0001] The invention relates to the field of network caching, in particular to an Internet caching response system and method based on content identification. Background technique [0002] Network caching is a key technology to support efficient content distribution, and is crucial to today's Internet where content distribution is the main business. As a key link in the network cache, the cache response method is an important factor affecting the performance of the network cache. [0003] The current Internet architecture is host-centric, and the acquisition of content depends on the establishment of connections between hosts. The content cache is deployed on the application layer. To obtain the cache, it is necessary to first determine the location of the host where the cache is located. Only after establishing a connection with the host can it respond to the content requester and transmit the required content. With the current mainstream content distribut...
