Problems solved by technology

[0003] In the prior art, the method of realizing data forwarding according to the VLAN tag with specific forwarding target information needs to implement a specific forwarding strategy for each intermediate node in the switch matrix. When the intermediate node is added or removed, it is necessary to target Various VLAN tags need to be configured with corresponding forwarding entries, which is not easy to maintain the system configuration

Abstract

The invention discloses a method and a device for data forwarding. The method comprises the following steps: receiving a message with appointed forwarding purpose; adding a double-layer virtual local area network tag to the message according to the forwarding purpose, wherein the double-layer virtual local area network tag comprises an outer-layer virtual local area network tag and an inner-layer virtual local area network tag; carrying out point-to-point data forwarding on the message with the double-layer virtual local area network tag through a data forwarding tunnel, wherein the formation of the data forwarding tunnel comprises the following processes: forming a logic exchange system by establishing a cascade relation of exchange units inside an exchange matrix, configuring virtual local area network attribute of a port of each exchange unit according to the preset forwarding strategy and forwarding contract, and configuring the forwarding item from the port of each exchange unit to any port of any exchange unit inside the logic exchange system to form the data forwarding tunnel. Due to adoption of the method and the device, difficulty in system configuration and maintenance is reduced, and the configuration requirement of exchange units in data forwarding is reduced.

Description

technical field [0001] The invention relates to data communication technology, in particular to a data forwarding method and device. Background technique [0002] The data forwarding mode in the switching matrix in the prior art is to forward the MAC layer data based on the MAC header information of the message, or to perform the IP layer data forwarding according to the IP header information of the message. However, in some applications, the packets connected to the switching matrix are unpredictable, and data forwarding cannot be completed according to the MAC header and IP header information of the packet itself. Instead, some information with forwarding policies needs to be added to the packet. to complete the forwarding. In the prior art, the forwarding target information is carried on the outer VLAN tag of the message, or the inner and outer VLAN tags, and then forwarded according to the VLAN tag. [0003] In the prior art, the method of realizing data forwarding acc...
