Embodiment Construction

[0031] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0032] The idea of ​​the embodiment of the present invention is to use the frame sent by the topology discovery protocol to determine whether there is a duplicate MAC address in the RPR ring network by adding the node identifier in the frame and combining the MAC address. Further, the TTL in the frame is used to determine the position of a node with a duplicate MAC address.

[0033] There are three types of frames in the topology discovery protocol, and any type of frame can be used as a carrier to realize RPR ring network control MAC address conflict detection. These three types of frames are RPR control frames, RPR data frames, and self-defined standard frames similar to RPR. All three types of frames can disseminate the identification of this node and the MAC address to other nodes, and the implementation principle is the same. These three ty...

Abstract

The invention discloses a method as well as a system to detect the repeated media access control MAC addresses in a resilient packet ring RPR. The method comprises the following steps: constructing a first detecting frame: a first node sends the first detecting frame to a second node, and the first detecting frame is constructed with the MAC address and the node identification of the first node; constructing a second detecting frame: a third node sends the second detecting frame to the second node, and the second detecting frame is constructed with the MAC address and the node identification of the third node; the second node obtains the result whether the repeated MAC addresses exist according to the MAC addresses and the node identifications in the first detecting frame and the second detecting frame. When the repeat conflict that the MAC addresses of two or a plurality of nodes exists on the ring RPR, the conflict can be fast detected by utilizing the invention, and an alarm is given after positioning the conflict nodes betimes and precisely, thereby being able to fast solve the conflict problem of the MAC addresses on the ring.

Description

technical field [0001] The invention relates to an address monitoring method and system of an elastic grouping ring network, in particular to a method and system for detecting duplicate media access control addresses on the elastic grouping ring network. Background technique [0002] Resilient Packet Ring (RPR, Resilient Packet Ring) technology is a two-layer ring network technology, which provides a good networking solution for broadband Internet Protocol (IP, Internet Protocol) metropolitan area network operators. RPR is different from traditional The most attractive feature of multi-address call (MAC, Multi Address Call) is its carrier-level reliability, which makes it not only limited to processing data-oriented service transmission requirements, but also can form a comprehensive transmission solution for multi-service transmission . It effectively combines the carrier-class features of Synchronous Digital Hierarchy (SDH, Synchronous Digital Hierarchy) with the data ser...
