Embodiment

[0042] Such as Figure 1 to Figure 2 As shown, the policy-based routing method for multi-WAN port routers in the case of multi-operator access includes the following steps:

[0043] (S1) The router receives the DNS resolution request sent by the intranet user, selects a WANx port as the exit for the DNS resolution request according to the preset policy routing rules, and sends the DNS resolution request, where x is the WAN port setting number.

[0044] Specifically, the preset policy routing rules include a default policy and a manual policy manually configured by the user. When selecting an exit for a DNS resolution request or data packet according to the preset policy routing rules, it is preferentially judged whether there is the Manual policy, if it exists, select the WANx port specified by the manual policy as the egress, if it does not exist, select the egress according to the default policy.

[0045] In the step (S1), when there are more than two WANx ports specified ...

Abstract

The invention discloses a policy-based route selection method for multi-WAN port routers in the case of multi-operator access, which includes firstly selecting an exit for a DNS resolution request according to a preset route policy route selection rule, and then passing the set route Policy rules, ISP policies and load rules select the egress for the corresponding data packets. The present invention improves the processing efficiency of concurrent access to the same service through the setting of the route selection cache module, enables the route selection query to directly select the exit, avoids a large number of repeated operations of the router and consumes performance, and at the same time, through the configuration of the ISP strategy, effectively solves the problem of In order to avoid the shortcomings of domain name resolution failure and long response when accessing between lines of different domestic operators, it is really possible to access the service of that operator, and send it from the exit of that operator's line.

Description

technical field [0001] The invention relates to the technical field of network communication, and in particular relates to a policy-based routing method for multi-WAN port routers in the case of multi-operator access. Background technique [0002] With the popularity and application of the network becoming more and more extensive, the scale of the user's network usage is getting larger and larger, and the requirements for bandwidth are getting higher and higher. With the development of my country's network construction, low-bandwidth broadband access is increasingly popular and low-cost. However, the cost of commercial high-bandwidth access is still high. Therefore, using multiple low-bandwidth simultaneous accesses to improve the overall network bandwidth has become another cost-effective alternative solution widely adopted by small and medium-sized enterprises. [0003] Driven by this demand, the standard single-wan-port broadband router equipment has been unable to meet...
