Problems solved by technology

It can be seen that the currently applied method of manually setting the east and west directions of communication nodes is heavy and inefficient, resulting in high RPR ring operation and maintenance costs; and operators are likely to remember wrongly or forget the east and west directions of communication nodes that have been set. Causes errors in setting communication nodes east and west, especially when the RPR ring contains a large number of communication nodes, the error rate of setting communication nodes east and west is higher, which seriously affects the normal communication of the entire RPR ring

Embodiment 1

[0059] Embodiment 1: Only one communication node is set on the RPR ring during initial networking.

[0060] see figure 2 , figure 2 It is a schematic diagram of the ring configuration in Embodiment 1 of the present invention. figure 2 Only node A 210 is included on the RPR ring in , and the dotted line connection between the ring interface 211 and the ring interface 212 represents that the loop interface 211 and the ring interface 212 are internally connected.

[0061] In practical applications, the RPR ring may further include other communication nodes, but all other communication nodes except node A210 are in the shutdown state, and the communication nodes in the shutdown state only transparently transmit the communication information received by themselves , without performing other operations.

[0062] When performing loop configuration, node A 210 determines its own loop according to a preset loop configuration policy. The ring direction configuration strategy may ...

Embodiment 2

[0074] Embodiment 2: A communication node is added to the RPR ring.

[0075] see image 3 , image 3 It is a schematic diagram of the ring configuration in Embodiment 2 of the present invention. image 3 The RPR ring in includes node 310 and node 320 . Among them, the node 310 is originally arranged on the RPR ring, and the node 320 is newly added to the RPR ring. Under normal circumstances, the node 310 should have determined itself as the master node and send its own ring direction information; the node 320 defaults itself as the slave node when it newly joins the RPR ring.

[0076] When the node 320 receives the ring information from the node 310, the node 320 compares the priority contained in the received ring information with its own priority, if the priority of the node 320 is relatively high, the node 320 determines that it is the master The node determines its own ring direction according to the preset ring direction configuration strategy, and then sends its own ...

Embodiment 3

[0086] Embodiment 3: The communication node is deleted on the RPR ring.

[0087] see Figure 4 , Figure 4 It is a schematic diagram of the ring configuration in Embodiment 3 of the present invention.

[0088] Figure 4 The RPR ring in includes node A 410, node B 420, node C 430, and node D 440, and each communication node has determined the ring direction.

[0089] During the application process, the communication node may have a single board failure or a complete machine failure, which will cause it to fail to perform ring configuration or even communicate normally. Assume that node B 420 has a single board failure / whole machine failure.

[0090] When the node B 420 has a single board failure / whole machine failure, the node B 420 applies the existing technology to set itself to the shutdown state. In this way, node B 420 only transparently transmits the communication information received by itself, and does not perform other operations. At this time, it can be considere...

Abstract

This invention discloses a method for realizing hoop configuration in a ring network, in which, when a node of the receiving party receives hoop information from the node of the transmission party, it compares its own priority with that of the node of the transmission party to determine the hoop of its own used in ordinary communication. This invention also discloses a device for realizing hoop configuration in the ring network including a RPR management unit, an interface unit and a hoop association unit, which is used in judging if its own position has the relative maximum priority and determines hoop of its belonged devices at ordinary communication based on the judgment result.

Description

technical field [0001] The invention relates to a method and a device for realizing ring configuration in a ring network. Background technique [0002] With the development of the communication network, a technical standard of a resilient packet ring (Resilient packet ring, RPR) is currently proposed. RPR has a double-ring reverse ring network structure, independent of the physical layer, and has the advantages of carrier-class failover capability and high bandwidth utilization, so it is gradually favored by operators. [0003] see figure 1 , figure 1 It is the structure diagram of RPR network. figure 1 , there are three communication nodes on the RPR ring: node A 110 , node B 120 , and node C 130 . Node A 110, node B 120, and node C 130 are connected to each other to form two loops for communication, one of which is clockwise, usually called 0 ring; the other loop is counterclockwise, It is usually referred to as ring 1; the clockwise and counterclockwise refer to the ...
