Embodiment Construction

[0055] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0056] figure 1 A network architecture of an embodiment of the present invention is shown, wherein an autonomous domain includes a content access client (for example, a PC, a mobile terminal, a tablet computer, etc.), a router (CR), a content cache cluster (CCS), and a content routing policy Decision Server (CRDS). Multiple autonomous domains can exchange content routing information through CRDS.

[0057] A content router (CR) is set at the edge of the network. The router uses the built-in storage of the device to provide the first-level content cache. When the content requ...

Abstract

The invention provides a context routing processing method, network element equipment and a network server. The process context routing method includes: receiving context access information reported by context routing devices in a local area by the network server; computing frequency of historic context access according to context addressing in the context access information, and adjusting a context routing list according to the frequency; and issuing the context routing table adjusted to all context routing devices in the local area. By the context routing processing method, conflict between context flow transmission efficiency and cache hit ratio can be eliminated, so that higher integral transmission performance can be realize by least cost and cache hit ratio is increased.

Description

technical field [0001] The present invention relates to content network related technologies, in particular to a method and device for processing content routing. Background technique [0002] According to Cisco (Cisco) VNI (Visual Network Index, Visual Network Index) statistical forecast, more than 90% of Internet traffic is Web Data (data), file sharing, and repeatable content such as video. These traffic uses cache, The forwarding mode is more efficient, while the existing IP network supports an end-to-end transmission model, which is inefficient under the existing Internet traffic characteristics. [0003] In the past 20 years, some technologies have been used to improve the transmission of these content traffic, such as website mirroring in the 1990s, Web Cache (cache memory) that appeared in the late 1990s, and CDN (Content Delivery Network) introduced after 2000. , content delivery network) all cache the content closer to the end user, reducing the repeated transmiss...
