Problems solved by technology

This approach makes the business management system (BSS) and operation support system (OSS) not clearly divided, resulting in unclear business logic and increasing the complexity of the management system
In each business opening process, the business administrator needs to manually operate a large number of devices, the business opening speed is slow, the efficiency is low, and errors are prone to occur
Due to the lack of an overall view of resources, some devices in the network often have insufficient capacity, making it difficult to guarantee customer resources

Embodiment Construction

[0023] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. In the drawings, the same reference numerals denote the same components or elements.

[0024] The basic idea of ​​the present invention is to add resource abstraction concept in CDN, and configure equipment to count and manage resource abstraction. Resource abstraction is to build a model for the concurrency, storage, bandwidth and other service capabilities in the CDN to manage the above resources in a unified manner.

[0025] figure 1 It is a system structure diagram of the content distribution network of the present invention. Such as figure 1 As shown, the system includes resource management device 11 , GSLB 12 , SLB 13 and cache server 14 . Among them, the resource management device 11 collects resource information from the GSLB 12, the SLB 13, and the Cache 14, such as the storage capacity ...

Abstract

The invention discloses a content routing method, load balancing equipment and resource management equipment in content distribution network. The content routing method comprises: GSLB receives domain name resolution request from LDNS and select SLB according to resource dispensing strategy based on resource information coming from resource management equipment; returns the SLB to browser via LDNS; the browser sends content request to the SLB; the SLB selects cache servers according to local resource distribution strategy and based on local resource information from resource management equipment, and forwards the content request to cache server. The content routing method and equipment in content distribution network of the invention harmonizes new demand and existing technology, protects original investment, endows original system with higher performance, implements fine dispatching for dispensing content routing and service ability for abstract resource of CDN.

Description

technical field [0001] The present invention relates to a content delivery network (Content Delivery Network, CDN) technology in the field of data communication, and in particular to a content routing method, a load balancing device and a resource management device of a content delivery network. Background technique [0002] CDN, that is, content distribution network, is to publish the content of the website to the "edge" of the network closest to the user by adding a new layer of network architecture to the existing network, so that users can obtain the required content nearby and solve the problem of network Congestion situation, improve the response speed of users accessing the website. Technically, it fully solves the problem of slow response speed of users visiting websites due to reasons such as small network bandwidth, large number of user visits, and uneven distribution of outlets. [0003] A CDN node usually consists of a server load balancing device (Server Load B...
