Embodiment Construction

[0039] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0040] The DCN network includes multiple equipment network elements, and divides multiple network elements according to the acceptable network scale. In the invention, the scene of being adjacent to the backbone domain is not described. If a certain area is not adjacent to the backbone domain, according to the OSPF protocol It is stipulated that routes in this area and routes in other areas cannot learn from each other. In order to solve this problem, a bridge domain is added to the OSPF domain. This bridge domain is connected to the backbone domain, and the routing information of irregular domains that are not directly adjacent to the backbone domain is d...

Abstract

The invention discloses a data communication network (DCN) irregular domain intercommunicating method and device in packet transport network (PTN) equipment, which relates to the PTN equipment management and control planar technology field and comprises the following steps. The common domain adjacently connected between the irregular domain and the backbone domain is defaulted as a bridging domain when the single node of an expanded or area board router (ABR) fails and causes an irregular domain that is not adjacent to the backbone domain in the network. The irregular domain, through the bridging domain, spreads the routing information of the irregular domain to the backboard domain. The backboard domain, through the bridging domain, spreads the global routing information of the backboard domain to the irregular domain. With the invention, irregular domains can be intercommunicated automatically; and the problem can be solved that automatic recovery cannot be accomplished when the single node of an ABR fails and causes the entire domain to be unreachable, therefore, accomplishing the interconnection and intercommunication of DCN of PTN equipment.

Description

technical field [0001] The present invention relates to the technical field of PTN (Packet Transport Network, Packet Transport Network) equipment management control plane, in particular to a method and device for intercommunication between DCN (Data Communication Network, data communication network) irregular domains in PTN equipment. Background technique [0002] In the telecommunications network, in order to manage the equipment and network elements scattered in various places, major equipment manufacturers have developed their own DCN. With the continuous expansion of the scale of the telecommunications network, in order to solve the DCN interconnection between devices, routing protocols such as OSPF (Open Shortest Path First, Open Shortest Path First), BGP (Border Gateway Protocol, Border Gateway Protocol) and other routing protocols are introduced to be superimposed on the DCN network. above. Patent CN200510033350.9 proposes to divide the DCN network into multiple doma...
