A Data Center Addressing and Active-standby Switching Method Based on Service Routing Tree

Abstract

The invention discloses a data center addressing and active / standby switching method based on a service routing tree, which mainly includes that in a normal state, a client requests a service routing tree from a main center system when starting, and the client obtains the service routing tree information , the client initiates connection and related service requests to the main central system based on this information to complete related business processing; the connection and service requests initiated by the client to the main central system are abnormal and enter an abnormal state. Try to enter the active / standby switchover process; after the active / standby switchover, it enters the disaster standby state, and the client initiates a connection and service request to the standby center system to complete related business processing. Ready to switch back. The invention can adapt to the network switching of a single system, can realize the network switching in minutes, does not require the client to perform configuration changes at the operating system level, does not rely on additional equipment resources, and reduces investment and operation and maintenance costs.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a data center addressing and active / standby switching method based on a service routing tree. Background technique [0002] In modern society, the stability of the "digital world" affects all aspects of people's livelihood and even the military field. Achieving high availability of information systems has become one of the primary goals of almost every software project. The system is deployed in a single data center through active / standby or clustering, and the high availability goal is only achieved in this center. From a higher level, a "data center" will also form a "single point", especially in the event of earthquakes, fires, wars and other disasters, how to ensure that the system can still provide services to users normally, this problem is increasingly leading. More and more software projects are starting to consider high-availability solutions for multi-data center...

Problems solved by technology

[0008] The existing IP address-based switching, DNS server-based switching, and load balancing device-based switching mainly have the following obvious defects: the IP address-based switching technology needs to be manually performed by the operation and maintenance administrator, and the switching takes a relatively long time. And it will switch the entire subnet, which cannot adapt to the switching of a single system; both switching technologies based on DNS server and load balancing equipment require additional investment in equipment resources; switching technology based on DNS server needs to introduce additional technical means to achieve The content of the two DNS servers is automatically synchronized; based on the switching technology of the DNS server, the operating system of the client is required to configure the DNS server, which increases the cost of the client; among the three mainstream technical solutions, only the system IP address level is provided. information, it is impossible to provide further service-level information, and thus it is impossible to realize the downgrade processing of some services after the active-standby switchover; the three mainstream technical solutions cannot control the grayscale access of the traffic after the active-standby switchover, and thus cannot guarantee the standby center stable operation of the system
