Resilient packet ring based graphical display method for service topology

Abstract

The invention discloses a method for displaying a business topology graphically based on a resilient packet ring (RPR). The RPR comprises two sub rings and a plurality of sites. The method comprises the following processes: A. information of the sites and interfaces obtained by business is inquired from a network management configuration; B. business information among internal interfaces of source / host sites is obtained by the inquiry to a control address of the business media accessing; C. information of middle sites among the source / host sites is added through the inquiry to information of the RPR network topology; D. a business topology graphic is created according to the business information of the source / host sites and the information of middle sites. The invention realizes the display of the RPR business topology graphically, which not only makes the inquiry process of the RPR business topology simple and convenient, but also makes the inquiry result of the RPR business topology clear and intuitive so as to ease largely the operation and maintenance of the business.

Description

technical field [0001] The present invention relates to the technical field of network communication, and is mainly used in the embedded RPR (Resilient Packet Ring, Resilient Packet Ring) multi-service transmission network based on SDH (Synchronous Digital Hierarchy, Synchronous Digital Series), especially relates to a service based on Resilient Packet Ring Topology graphical display method. Background technique [0002] The IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) 802.17 standard defines the physical layer specification and packet data access method of the elastic packet ring. It adopts a double-ring structure, and the outer ring is clockwise and the inner ring is counterclockwise. Two-way data transmission . The topology of the RPR ring network is as follows: figure 1 As shown, the two sub-rings are respectively identified as sub-ring 0 (ringlet 0) and sub-ring 1 (ringlet 1), and they transmit control sig...

Problems solved by technology

However, the existing technology can only obtain the service topology through manual query, and generally try to obtain the service path (that is, the service topology) by means of query performance, service configuration, etc.

Queries are quite cumbersome, requiring users to judge by combining various information, which puts forward high requirements for users; as for whether the service channel is normal, users cannot be clear at a glance; and when multiple sites have concurrent services, it supports space reuse and multi-service shared ports It is more difficult to accurately know the final service topology in the case of switchover caused by local failure of the ring or ring
