Embodiment Construction

[0046] A more complete and better understanding of the invention, and many of its attendant advantages, will readily be learned by reference to the following detailed description when considered in conjunction with the accompanying drawings, but the accompanying drawings illustrated herein are intended to provide a further understanding of the invention and constitute part of the invention.

[0047] Since the fault avoidance routing method and system proposed by the present invention are applicable to any data center network with a regular topology, here we take a new type of data center network structure—fat-tree structure (Fat-tree) as an example to illustrate how to apply the present invention .

[0048] The fat tree adopts the third-layer switch with routing function to form a network. The network structure is divided into four layers. The top layer is the core layer, the second layer is the aggregation layer, the third layer is the edge layer, and the bottom layer is the ...

Abstract

The invention relates to a universal routing method and a universal routing system for a data center network. The method comprises the following steps of performing link and neighbor detection, namely detecting a connected link and a neighbor router adjacent to a router and storing detection results into an adjacent equipment list; performing equipment training, namely broadcasting the router per se, learning other routers in the network and storing results into a full-network equipment list; performing link failure deduction, namely deducing the neighbor router and associated link failure according to the learnt routers and storing results into the adjacent equipment list and a full-network link fault list; performing link failure training, broadcasting the link failure of the router per se, learning other link failures in the network and storing results into the full-network link fault list; constructing a base routing list and an elusion routing list; and inquiring the routing lists. Compared with the prior art, the universal routing method and the universal routing system provided by the invention are simpler and more efficient and have better fault handling capability.

Description

technical field [0001] The invention relates to a routing method and system, in particular to a general routing method and system for a data center network. Background technique [0002] The data center is the provider center of various application services of the enterprise, and the center of data calculation, exchange and storage. It combines advanced network technology and storage technology, carries more than 80% of the service requests and data storage capacity in the network, and provides services and operating platforms for the healthy operation of customers' business systems. [0003] With the increasing scale of the data center, the existing tree network topology will inevitably have a bandwidth bottleneck problem at the core layer of the network, resulting in a decline in the overall performance of the network in terms of transmission delay and transmission efficiency. In order to solve the bottleneck problem of bandwidth communication at the core layer of the net...
