Embodiment 1

[0037] The realization method of the distributed dynamic routing based on Raft algorithm of the present invention, described method comprises the following steps:

[0038] (1) Distributed dynamic routing adopts a distributed architecture and consists of three routing hosts. The upper layer of the routing host is responsible for evenly distributing access traffic to the routing nodes in each routing host by the load balancing component;

[0039] (2) External services are accessed through the domain name provided by the platform, and the domain name server points to the load balancing component through a unified domain name suffix;

[0040] (3) As the traffic entrance of the entire platform service, the routing node is responsible for forwarding all external access requests to the cloud platform system and distributing the access traffic to six back-end service instances;

[0041] (4) The bottom layer of the routing host is the storage node, each routing node corresponds to a st...

Abstract

The invention discloses a method and system for realizing distributed dynamic routing based on Raft algorithm, belongs to the technical field of cloud computing data centers, and solves the problem of dynamic call of elastic resources in distributed dynamic routing cloud computing in the prior art. The technical solution adopted is: including the following steps: the upper layer of the routing host is responsible for evenly distributing the access traffic to each routing node by the load balancing component; the external service is accessed through the domain name provided by the platform; the routing node is responsible for forwarding the external traffic to the cloud platform system access requests, and distribute the access traffic to the back-end service instances; the bottom layer of the routing host is the storage node, and the storage nodes form a distributed storage component, which is responsible for storing the mapping relationship between each domain name and the back-end service instance; the Raft algorithm is used to maintain the storage node data Consistency, each routing node only needs to read the mapping data from the local storage node; the administrator is responsible for adding, deleting, and modifying the mapping data in the storage node through the management node.

Description

technical field [0001] The invention relates to the technical field of cloud computing data centers, in particular to a method and system for realizing distributed dynamic routing based on Raft algorithm. Background technique [0002] Dynamic routing can automatically establish its own routing table according to the specific routing information exchanged between routers, and can automatically adjust in time according to changes in links and nodes. When a node or a link between nodes in the network fails, or there are other available routes, dynamic routing can select the best available route and continue to forward packets. [0003] In a distributed system, the consistency problem means that for a group of servers, given a set of operations, a protocol is required to make the final result consistent; that is, when a server receives a set of instructions from the client, it must communicate with other servers Communication ensures that all servers receive the same commands i...
