Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0036] Before introducing the embodiments of the present application, in order to make it easier for those skilled in the art to understand the network nodes in the embodiments of the present application more clearly, the following first introduces them in detail.

[0037]CDN, also known as content delivery network. CDN is a value-added network built on the existing IP network infrastructure, and is a one-layer network architecture deployed at the application layer. The core of CDN...

Abstract

The invention provides a fault detection method, an overall load balancing server and a resident gateway. The fault detection method is applied to the overall load balancing server, and comprises the steps of sending a fault detection message to a first content distribution network; and judging whether the content distribution network node has a fault according to fault feedback of the first content distribution network node aiming at the fault detection message, and if yes, informing the resident gateway of the condition whether the first content distribution network node has the fault, thus allowing the resident gateway to forward an Internet content access request triggered by user equipment to a second content distribution network node connected with the first content distribution network node. By using the method provided by the embodiment of the invention, the resident gateway can timely learn the fault condition of the CDN node connected therewith, so that the situation that the CDN can also provide Internet content to the user normally when in fault is ensured.

Description

technical field [0001] The application relates to the technical field of content distribution network, in particular to a fault detection method, a data processing method, a global load balancing server, a resident gateway and a fault detection system. Background technique [0002] GSLB (Global Server Load Balance, global load balancing), which mainly implements traffic allocation between servers in different regions on the WAN (including the Internet). For example, GSLB can configure RGW (Residential Gateway, resident gateway) closer to users Or serve a better CDN (Content Delivery Network, content distribution network) node to ensure that the best CDN node is used to serve the nearest users, thereby ensuring the quality of Internet access. Contents of the invention [0003] However, the inventor found during the research process that based on the mobile CDN architecture, since the CDN node near the eNB is closer to the user, GSLB generally configures the CDN node near th...
