Abstract

The invention discloses wide area network bandwidth classification methods, devices and system. According to a method, a first provider edge obtains a message sent by a first customer edge, identifiesan application corresponding to the message, and packages a forwarding label stack corresponding to the application for the message; the forwarding label stack is issued to the first provider edge byan SDN (Software Defined Network) controller; the first provider edge forwards the message to a next hop provider edge according to a label in the forwarding label stack; and after the next hop provider edge receives the message, the next hop provider edge forwards the message according to the label in the forwarding label stack, until the message is forwarded to a second customer edge. Accordingto the methods, the devices and the system, a segmented routing and application-based policy routing combined scheme is provided, application or business-based wide area network bandwidth classification can be realized, different businesses of different customers can be forwarded according to different bandwidths or delay polices, practical business requirements of the customers are combined fully, bandwidth waste is avoided, and links are utilized fully.

Description

technical field [0001] The present application relates to the field of network technology, in particular to a wide area network bandwidth classification method, device and system. Background technique [0002] Due to the complexity of the algorithm, the traditional IP routing technology based on the longest mask matching cannot be implemented using an application specific integrated circuit (English: Application Specific Integrated Circuit, abbreviation: ASIC), and the performance based on software cannot meet the increasingly The increasing network scale has become a bottleneck in the development of high-speed networks, so Multi-Protocol Label Switching (English: Multi-Protocol Label Switching, abbreviation: MPLS) emerged under this background. MPLS not only solves the problem of routing and forwarding performance, but also because of its label forwarding feature, it can define the forwarding path of packets at the edge router, which is very suitable for traffic engineering...
