Problems solved by technology

[0004] Because the router only uses the link connected to the active member port of one switch for data transmission, while the link connected to the standby member port of the other switch is idle and does not transmit data, occupying the link bandwidth, resulting in link failure. Bandwidth cannot be used effectively

Abstract

The embodiment of the present application discloses a data transmission method, which is used to improve link bandwidth utilization and avoid waste of network resources. The method in the embodiment of the present application includes: the forwarding device creates a first virtual local area network VLAN sub-interface and a second VLAN sub-interface for the TRUNK interface; the forwarding device configures the first virtual local area network identification VLAN ID encapsulated in the first VLAN sub-interface and the second VLAN sub-interface Encapsulated second VLAN ID, the first VLAN ID is used to instruct the forwarding device to use the first VLAN sub-interface to transmit data according to the first VLAN ID, and the second VLAN ID is used to instruct the forwarding device to use the second VLAN sub-interface according to the second VLAN ID Data transmission: the forwarding device uses the first VLAN sub-interface to transmit data on the first link through the first physical interface, and uses the second VLAN sub-interface to transmit data on the second link through the second physical interface. The embodiment of the present application also provides a forwarding device. The embodiments of the present application can effectively improve link bandwidth utilization and avoid waste of network resources.

Description

Technical field[0001]The present application relates to the field of communications, and in particular, to a data transmission method and a forwarding device.Background technique[0002]When the router is interconnected by the switch, it is easy to display a single point fault when using a single link interconnection, causing business interruption. In order to avoid single-point failure, improve network reliability, but also in order to improve link bandwidth between routers and switches, multi-link interconnection methods are usually employed.[0003]At present, in order to meet the network reliability, the link bandwidth is improved, the router is running the master-standing Trunk mode (Trunk has two member ports, one member port is mainly used, and the other member port is alternate), the router will only use the main use The exchange of ports is connected to port aggregation, while switches connected to the standby member ports are in the standby state.[0004]Since the router uses on...
