Embodiment 1

[0026] The embodiment of the present invention provides a forwarding method. see figure 2 , figure 2 It is a flowchart of a forwarding method provided by an embodiment of the present invention, and the method includes:

[0027] 201: The physical outgoing interface of the first network element fails, triggering the shutdown of the incoming interface of the first network element. Determine the total bandwidth of the disabled inbound interfaces based on the total bandwidth of the failed physical outbound interfaces. The first network element includes multiple physical outgoing interfaces. The failed physical outgoing interface is included in the multiple physical outgoing interfaces. The first network element includes multiple incoming interfaces, and the closed incoming interface is included in the multiple incoming interfaces. The multiple physical outgoing interfaces are used to forward traffic received by the multiple incoming interfaces.

[0028] During specific impl...

Abstract

Provided is a forwarding method, including: if a physical outlet interface of a first network element has failed, triggering an inlet interface of the first network element to close, determining the total bandwidth of the closed inlet interface according to the total bandwidth of the failed physical outlet interface, wherein the first network element includes a plurality of physical outlet interfaces and a plurality of inlet interfaces, with the plurality of physical outlet interfaces being used for forwarding the traffic received by the plurality of inlet interfaces; and the closed inlet interface triggering the network connected to the plurality of inlet interfaces to send to a second network element the traffic to be sent to the closed inlet interface, so that the second network element can forward the same, wherein the second network element is a backup element of the first network element. In addition, also provided is a corresponding forwarding device. The forwarding method and device in the embodiments of the present invention can solve the technical problem that when a part of the physical outlet interfaces of the network element has failed, the network element forwarding the traffic received by an inlet interface thereof via the other physical outlet interfaces may cause congestion in the other physical outlet interfaces.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a forwarding method and a forwarding device. Background technique [0002] Using NEs to connect two networks is a typical network topology. In the network topology structure, the two sides of the network element are respectively the first network and the second network. The network element may have multiple incoming interfaces and multiple physical outgoing interfaces. The network element may be connected to the first network through the multiple incoming interfaces, and connected to the second network through the multiple physical outgoing interfaces. A network device of the first network may send traffic to a network device of the second network through the network element. After receiving the traffic from the first network through the ingress interface, the network element may forward the traffic to the second network through the physical outbound int...
