Embodiment Construction

[0026] The core of the present invention is to build a PBT network architecture with the same source and different destinations, so that when one destination device fails, other destination devices are used to forward data without affecting the normal operation of the network and improving network reliability.

[0027] Referring to Fig. 2, it is a flow chart of the method of the present invention, comprising the following steps:

[0028] Step 201: Set the target PBT devices as mutual backups, wherein there are at least two target PBT devices;

[0029] Step 202: configure the link between the source PBT device and a destination PBT device as a working link, and configure the links between the source PBT device and other destination PBT devices as protection links;

[0030] Step 203: When both the working link and the destination PBT device connected to the working link are normal, forward the traffic through the working link, and when the working link fails or / and the destinati...

Abstract

The invention relates to a PBT network flow control method. The PBT network comprises a source PBT equipment and at least two destination PBT equipments, which are respectively backups of the other one. The method comprises configuring the link between the source PBT equipment and one destination PBT equipment as the working link; and configuring the link between the source PBT equipment and the rest of PBT equipment as the protection link. When the working link and the destination PBT equipment connected with the working link are normal, the flow is transmitted through the working link. When the working link or / and the destination equipment connected with the working link fails / fail, the flow is switched to the normal protection link. The invention adopting a PBT network structure with the same source and hetero-sink can ensure the network safety. Corresponding to the method, the invention also provides a PBT network flow control device.

Description

technical field [0001] The present invention relates to the field of Ethernet technology, in particular to a PBT (Provider BackboneTrunk, operator backbone network transmission) network flow control method and device. Background technique [0002] With the rapid development of the metropolitan area network, higher and higher requirements are put forward for the multi-service support, scalability and reliability of the Ethernet, and various Ethernet extension technologies appear. The representative of these Ethernet extension technologies One is MiM (MAC in MAC) technology. MiM uses double-layer MAC address headers to encapsulate packets, and provides higher service support capabilities by adding outer MAC headers and service extension labels. By using two-layer MAC header information, MiM can allocate different tunnels according to service types , complete the isolation and differentiation of services, and improve the QoS (Quality of Service). [0003] PBT technology is an...
