Abstract

The invention relates to a data forwarding method and system, and particularly relates to the technical field of network communication. The method comprises the following steps: receiving a first link notification sent by a target leaf switch, wherein the first link notification comprises a first sharing coefficient and a first destination network address; when a target equivalent path of which a destination network address is a first destination network address exists in a local routing table, adjusting a first equivalent routing weight of the target equivalent path according to the first sharing coefficient, and the ridge switch realizes data forwarding in the target equivalent path according to the adjusted second equivalent routing weight. According to the scheme, each ridge switch can adjust the equivalent routing weight of each equivalent path according to the first sharing coefficient, so that the data flow in the hotspot path is reduced, the data flow does not need to be subjected to routing processing again, and the efficiency of solving the problem of packet loss or time delay on the hotspot path is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data forwarding method and system. Background technique [0002] SDN (Software Defined Network, Software Defined Network) is a new network innovation architecture. Its core idea is to separate the control plane of network equipment from the forwarding plane, so as to realize flexible control of network traffic, and provide core network and application innovation. good platform. [0003] In the data center network of the Clos architecture, there are multi-path routes between the Leaf (leaf switch) and the spine (spine switch). When a link between the two is faulty, it is easy to cause a hot path. There is a high probability of packet loss on some paths. For this possible packet loss and delay, SR (Segment Routing, segment routing) provides technologies such as OAM (Operation, Administration and Maintenance, operation, management and maintenance) and FRR (FastRero...
