Abstract

The invention discloses a method and equipment for flow equilibrium based on a flexible link group. The method is applied to network equipment at least comprising a first port and a second port and comprises the following steps: counting the VLAN flow transferred by the first port and the VLAN flow transferred by the second port; and determining whether the first port or the second port is blockedand the other one is idle or not according to a counting result, if true, migrating the VLAN flow of the blocked port to the idle port. By using the invention, the VLAN flow of the blocked port in the equipment can be migrated to the idle port, thereby completing a load sharing technology of Smart Link. The invention can ensure that the flow of a block link can be equalized in time under the existence of idle link, thereby avoiding blockage and realizing dynamic equilibrium of the flow.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a flow balancing method and equipment based on a flexible link group. Background technique [0002] When a downstream device is connected to an upstream device, a single point of failure is likely to occur in the single uplink mode, resulting in service interruption. Therefore, dual uplinks are usually used, that is, one downstream device is connected to two upstream devices at the same time, so as to avoid single point failures to the greatest extent and improve network reliability, such as figure 1 shown. [0003] Although dual uplink networking can improve network reliability, it introduces loops. Generally, loops can be eliminated through STP (Spanning Tree Protocol, Spanning Tree Protocol) or RRPP (Rapid Ring Protection Protocol, fast ring network protection protocol), but STP can only achieve second-level convergence speed, and is not suitable for Users with high requir...
