Embodiment Construction

[0038] In order to make the technical principles, features and technical effects of the technical solution of the present application clearer, the technical solution of the present application will be described in detail below in conjunction with specific embodiments.

[0039] The switching capacity, number of slots, and interface capacity of the core node router cannot meet the demand, especially after the deployment is completed. The operator hopes that the core node router can be elastically scalable. , the switching capacity and interface capacity can be expanded through multiple router devices, and multi-chassis cluster routers emerge as the times require.

[0040] Multi-chassis cluster refers to the use of cascading technology to interconnect the original single-chassis routers to form a new multi-chassis cluster system to expand the switching capacity, number of slots and interface capacity. A multi-chassis trunking system usually consists of a central switching chassis...

Description

technical field [0001] The present application relates to the technical field of network switching equipment, and in particular to a line card frame, a multi-frame cluster router, a line card frame route selection and a message processing method. Background technique [0002] A router is a network infrastructure device working on the third layer of the open system interconnection protocol model, that is, a packet switching device at the network layer. It has the ability to connect different types of networks and can select a packet transmission path. With the rapid development of the Internet, further requirements are put forward for routers as network infrastructure equipment; in many cases, the switching capacity, number of slots and interface capacity of core node routers cannot meet the requirements. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a line card frame, a multi-frame cluster router, a line card frame rou...
