Problems solved by technology

[0005] In order to maintain a better resource scheduling process in the network, when the above three methods of the prior art are used to switch the BGP egress, the traffic on the AS path corresponding to the current BGP egress will be directly interrupted, and the service user will It is obvious that the service is interrupted, and the interruption time is longer due to the slow update of BGP routes (the characteristics of BGP's own protocol cause the upstream AS to update to the routing table entries that use redundant BGP egresses during egress switchover), such as up to 15 seconds , or even more than 30 seconds, and directly interrupting the flow of the switched egress will also cause a high packet loss rate

Abstract

The invention discloses a data resource scheduling method, a first autonomous system and a second autonomous system. The data resource scheduling method comprises the steps that address resources of the first autonomous system are divided into a first route and a second route in advance, wherein the first route is used in an interface used in the first autonomous system in a process in which the first autonomous system does not switch the interface, and the second route is used in a to-be-switched interface temporarily in a process in which the first autonomous system switches the interface; then, when the first autonomous system switches the interface, the to-be-switched interface can be switched by preventing the interface from using the first route, and the to-be-switched interface is allowed to use the second route to transmit data to be transmitted to the first autonomous system temporarily in switching, so that to-be-transmitted data on a path corresponding to the to-be-switchedinterface is cached and transmitted, then data transmission interruption duration in interface switching is shortened effectively and packet loss rate is lowered.

Description

technical field [0001] The invention belongs to the technical field of routing-based network resource scheduling, and in particular relates to a data resource scheduling method, a first autonomous system and a second autonomous system. Background technique [0002] At present, BGP (Border Gateway Protocol, Border Gateway Protocol) is commonly used on the Internet to interconnect multiple AS (Autonomous System, Autonomous System), that is, the interface based on the connection between one AS and another AS is implemented using the BGP protocol. Docking, where the interface using the BGP protocol can be called a BGP egress, which is used to carry the inbound and outbound traffic of the AS during data transmission between the ASs. The AS establishes a corresponding BGP neighbor for each BGP egress for maintenance Routing policy corresponding to the BGP egress. [0003] As far as the AS is concerned, when the network quality of a BGP egress currently used by the AS is poor, for...
