Embodiment Construction

[0034] When the SIP distribution proxy device fails, it is prone to bottlenecks. Even if the SIP distribution proxy device adopts the active and standby dual machines, it will take a certain amount of switching time or the switching will fail due to the failure of the dual machines themselves, resulting in a global paralysis of the network, which is not conducive to business development. carry out. Therefore, there is an urgent need for the SIP distribution agent device to provide a reliable security backup mechanism to ensure the normal operation of the network to the greatest extent. In the event of a disaster, the business can still be carried out. The disaster resistance is strong, and it can have a continuous communication in times of crisis. lifeline.

[0035] In order to solve the above problems, embodiments of the present invention provide a network disaster recovery method and system. Embodiments of the present invention will be described in detail below in conjuncti...

Abstract

The invention provides a network disaster tolerance method and a network disaster tolerance system, which relate to the field of IP (Internet Protocol) communication and solve the problem of causing global paralysis when a failure occurs in an SIP (Session Initialization Protocol) distribution agent device. The method comprises the following steps: when a first SIP distribution agent device is incapable of processing received service request, the service request is transferred to a second SIP distribution agent device, the first SIP distribution agent device and the second SIP distribution agent device are backup devices with each other besides in normal work; and the second SIP distribution agent device processes the service request transferred by the first SIP distribution agent device. The technical scheme provided by the invention is suitable for being used in SIP network so that a flexible and reliable backup mechanism is realized.

Description

technical field [0001] The invention relates to the field of IP communication, in particular to a network disaster recovery method and system in the network environment of the next generation network (NGN) or IP multimedia system (IMS). Background technique [0002] With the popularization of mobile communication networks, users have higher and higher requirements for mobile communication service quality, and operators require that the network can continue to provide services after network nodes fail. At the same time, under the trend of increasing traffic volume, the processing performance of a single application server is limited, and it is urgent to expand the number of application servers to enhance the processing performance of the application server. The Session Initiation Protocol (SIP) distribution proxy device shields the increase in the number of application servers. Inside the network site, the performance bottleneck and expansion problems of the application serve...
