Embodiment Construction

[0060] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0061] Such as figure 1 As shown, a proximity cache-aware semi-centralized routing system includes several terminal nodes 3 , several routers 2 and a directory server 1 .

[0062] Both the terminal node 3 and the router 2 have a content caching function, and the directory server 1 has a complete list of cached content and cached node addresses, and the corresponding relationship between all cached nodes and their cached content in the network, and saves it as a routing information table, and the Routing information is regularly updated and maintained.

[0063] The cache nodes include terminal nodes 3 and routers 2 . Different terminal nodes 3 transmit information commands through the router 21, the terminal nodes 3 can directly transmit information commands to each other with the directory server 1, and adjacent routers 2 can direct...

Abstract

The invention relates to a semi-centralized routing method for proximity cache awareness, which mainly solves the problem of high load of a central control node in the prior art. According to the method, the load of a directory server is identified, and data are transmitted in different modes and methods, so that the purposes of reducing the load of the directory server and improving the user experience are achieved. The invention also relates to the semi-centralized routing system, which comprises a plurality of terminal nodes, a plurality of routers and a directory server, the terminal nodes can directly carry out information communication and information transmission with the directory server, and the terminal nodes can also carry out information communication and information transmission with the directory server through the routers; and information transmission can also be carried out between the routers.

Description

technical field [0001] The invention relates to a network technology, in particular to a semi-centralized routing method with proximity cache awareness, and also relates to a semi-centralized routing system with proximity cache awareness. Background technique [0002] The modern Internet is evolving toward high speed and broadband, and has developed into an integrated service transmission network combining multiple services such as data, voice, image and real-time multimedia information. According to the network index statistics and forecast released by Cisco, by 2022, the data traffic of the global IP network will reach an average monthly level of 396EB, an increase of more than 2 times compared with 2017. [0003] Among the massive network services, network audio and video services that require high real-time performance have gradually become the mainstream of Internet applications, and are expected to account for 82% of the total data traffic in 2022. The demand for mass...
