Embodiment Construction

[0046] The present invention will be further explained below in conjunction with an exemplary network egress management system, so as to provide a thorough understanding of the present invention. The present invention involves the following modules:

[0047] like figure 1 As shown, a multi-exit routing method includes the following steps:

[0048] 1) Set multiple network egress servers according to the deployment environment, each network egress server builds a tunnel link with the network forwarding server, and each network egress server periodically detects the routing hops of the destination addresses of all IP network segments in the specified area (ttl) and the delay value, the network egress server will detect the routing hops (ttl) of the destination address and the delay value to the path management center;

[0049] In step 1), the specified area is preset according to the location of the network egress server. For example, if the network egress server is located in ...

Abstract

The invention discloses a multi-outlet routing selection method, which comprises the following steps of performing a path detection module according to each network outlet server to realize real-timedetection of a destination address, uploading the destination address to a path management center, judging a routing strategy by the path management center, and determining an optimal path of the samedestination address in a plurality of network outlets. A user-defined module of a netfilter adopts an interval tree retrieval algorithm; therefore, the destination addresses of all the data packets are quickly classified and marked (a network outlet is specified), the user permission level is dynamically matched according to the source addresses of the data packets, and the corresponding available network outlet is specified based on the user permission level and the identification code of the network outlet server. Routing policy routing realizes routing outlet selection according to the fwmarkb packet identifier, and the method can adapt to dynamic adjustment of multiple outlets of the network, and realizes high-precision dynamic automatic selection of the multi-outlet routing.

Description

technical field [0001] The invention relates to the technical field of IP, in particular to a multi-exit routing selection method. Background technique [0002] With the rapid development of the network, the network deployment of the global network has become the choice of more and more enterprises. Then, the interconnection of network nodes is different from that of operators. How to use the limited network egress nodes to achieve higher precision Routing selection has become a key issue. The traditional IP technology implements route selection for policy routing and detailed routing. If there are multiple egresses for the routing destination, routing with a smaller granularity can only be achieved through a large number of detailed routes. It is difficult to achieve precise control and dynamic management of routing. [0003] The traditional routing methods are basically based on the matching rules of the destination. The network forwarding server only matches the detaile...
