Problems solved by technology

Figure 4 Schematic diagram of sharing a ring network for a large number of PBB-TE tunnels, such as Figure 4 As shown, each Ethernet switching node on the ring is connected to 10,000 subnets (Subnets). In order to segmentally protect the data flow of any two subnets, any two nodes on the ring need to send CCM messages to each other. These CCM The paths of the packets overlap each other, resulting in a large waste of network resources

Embodiment Construction

[0055] Figure 5 It is a flow chart of the data flow transmission method based on the PBB-TE segmented tunnel of the present invention, such as Figure 5 shown, including the following steps:

[0056] Step 500: Configure a PBB-TE tunnel according to different node types and link types.

[0057] The node types in this paper mainly include interconnection nodes and non-interconnection nodes, among which the interconnection nodes are intersecting nodes between rings. The link types in this paper mainly include shared links and non-shared links, where shared links are links shared by rings.

[0058] In this step, the method of configuring the PBB-TE tunnel is as follows Figure 6 as shown, Figure 6 For the flow chart of the tunnel configuration method of Ethernet multi-ring network of the present invention, comprise the following steps:

[0059] Step 600: the system configures the priority of the ring connected to the shared link.

[0060] In this step, the priority of the ...

Abstract

The invention provides a data stream transmission method based on a provider backbone bridge traffic engineering (PBB-TE) sectional tunnel, and a node. The method comprises the following steps of: configuring a PBB-TE which supports traffic engineering and a PBB-TE tunnel which supports the traffic engineering according to the difference between a node type and a link type; and transmitting a received message according to the configured PBB-TE tunnel. By the tunnel configuration method and the message transmission method, the system can conveniently maintain the tunnel maintenance, so the fault coupling among different rings is reduced, and the property of the Etheric multi-ring network is enhanced greatly.

Description

technical field [0001] The present invention relates to a provider backbone bridging technology (PBB-TE, ProviderBackbone Bridge Traffic Engineering) supporting traffic engineering, in particular to a data flow transmission method and node based on a PBB-TE segmented tunnel. Background technique [0002] With the introduction of the concept of Carrier Ethernet (CE, Carrier Ethernet), a connection-oriented Ethernet technology—Provider Backbone Transport (PBT, Provider Backbone Transport) emerged to meet the requirements of telecommunication networks. The basis of the PBT technology is the Provider Backbone Bridge (PBB, Provider Backbone Bridge) technology defined by IEEE 802.1ah. IEEE refers to the PBT technology as the Provider Backbone Bridge Traffic Engineering (PBB-TE, Provider Backbone Bridge Traffic Engineering) that supports traffic engineering. PBB-TE technology is based on PBB technology, and its core is to improve PBB technology. The source device of CE inserts the ...
