Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. However, it should be noted that the following embodiments are only examples for helping to understand the technical solutions, and are not intended to limit the present invention.

[0033] An embodiment of the invention

[0034] One embodiment of the invention discloses a network configuration method. The network configuration method is applied to a ring including n nodes, where n≥2, and n is a natural number. Optionally, n is 2, 3, 4, 5, 6, 7, 8, 10 or 20.

[0035] The network configuration method includes the following contents.

[0036] Take each node on the ring as the next ring node CCWC_LN (Clockwise Chain Working Channel_Leaving Node) of a forward chain working channel, and set up a forward chain working channel for each CCWC_LN, wherein, as figure 1 As shown, the establishment of each of the forward chain-shaped working channels ...

Abstract

The invention relates to a network configuration method, a ring network system and a node. A network is applied to a ring comprising n nodes, wherein n is not less than 2, n is a natural number, and the network is characterized in that each node on the ring is taken as a lower ring node CCWC-LN of a forward chain-shaped working channel, and the forward chain-shaped working channel is respectivelyestablished for each CCWC-LN. The invention has one advantage that as each node on the ring is taken as the lower ring node (CCWC-LN) of the forward chain-shaped working channel, the forward chain-shaped working channel is respectively established for each CCWC-LN, and services on the ring are packaged with WC-LSP (working channel-label switched path) labels during forwarding and can reach the lower ring nodes through the corresponding forward chain-shaped working channels. Therefore, the nodes on the ring do not perform forwarding according to each service, thereby greatly reducing the processing burden.

Description

technical field [0001] The invention relates to the communication field, in particular to a network configuration method, a ring network system and a node. Background technique [0002] Multi-Protocol Label Forwarding (MPLS) is a system for fast data packet switching and routing, which provides the capabilities of destination, routing, forwarding and switching for network data traffic. More specifically, it has mechanisms for managing various forms of communication flow. MPLS is independent of layer 2 and layer 3 protocols, such as Asynchronous Transfer Mode (ATM) and IP. It provides a way to map IP addresses to simple fixed-length labels for different packet forwarding and packet switching technologies. It is an interface to existing routing and switching protocols such as IP, ATM, Frame Relay, Resource Reservation Protocol (RSVP), Open Shortest Path First (OSPF), and more. [0003] In MPLS, data transmission occurs on Label Forwarding Paths (LSPs). LSP is a sequence of...
