Embodiment Construction

[0062] Aiming at the problem in the prior art that a VSU cannot be established between two network devices across WDM devices, an embodiment of the present invention provides a message forwarding method for VSUs interconnected across WDM devices, and the method is applied in the VSU In any of the network devices, the network device can be used as both the message sender and the message receiver. The following first introduces the message forwarding method of the network device as the message sender. This method can be realized by hardware or through Software Implementation. The procedure of this method is as follows figure 2 As shown, the execution steps are as follows:

[0063] S21: Obtain the first Higig packet.

[0064] When a network device needs to interact with another network device, it can send a Higig packet, and the Higig packet is defined as a first Higig packet.

[0065] S22: Determine the first port to send the first Higig packet according to the first Higig p...

Abstract

The present invention discloses a message forwarding method and device in a cross-wavelength division equipment interconnection VSU. The method comprises the steps of obtaining a first Higig message;according to a first Higig message head of the first Higig message, determining a first port for sending the first Higig message; according to a forwarding table item corresponding to the situation that the first port is used as a sending port, packaging the first Higig message head in the first Higig message to obtain a first E-Higig message; sending the first E-Higig message to a second port ofa virtual switching link (VSL) which is formed by the first and second ports via the first port, wherein the port types of the first and second ports are E-Higig. According to the scheme, the situations that the VSU can be established smoothly via two network devices, and the data communication between the VSU is normal can be guaranteed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a message forwarding method and device in a virtual switching unit (Virtual Switching Unit, VSU) interconnected across wavelength division devices. Background technique [0002] In many application scenarios (such as universities, enterprises and institutions, etc.), VSU is used for network topology deployment. VSU is a network system virtualization technology that combines two network devices into a single virtual network device. There is no hardware path between the two network devices in the VSU, and they need to be connected through a virtual switching link (Virtual Switching Link, VSL). Packets can be transmitted between the two network devices through the VSL. [0003] Among them, VSL can be implemented in the following two scenarios. The first is the scenario of optical fiber interconnection, which is a natural Layer 2 interconnection, and the network devices separ...
