Embodiment 1

[0048] In this embodiment, a method for dividing a routing domain is provided.

[0049] Such as figure 1 As shown, the method for dividing the routing domain according to this embodiment includes: step S102, the executing router performing routing domain division in the AS domain predetermines the divided routing domain, and floods the routers in the pre-determined divided routing domain The routing domain resets the data packet (can be the above-mentioned AreaResetLSA) as follows, the routing domain reset data packet designates the routing domain where the router interface in the AS domain is located; and step S104, the router that receives the routing domain reset data packet according to the route Domain reset packets carry out routing domain modification.

[0050] Among them, the specific implementation for the selection of the router can be: designate a fixed router to realize such a function, which is the centralized routing domain segmentation; any router in the domain...

Embodiment 2

[0088] When merging routing domains, all levels of routing are affected to varying degrees, and the more important impacts are on two levels, one is the routing domain change layer, and the other is the routing domain change parent layer. In view of this influence, the present embodiment will be described in detail below.

[0089] In this embodiment, a method for merging routing domains is provided.

[0090] Such as Figure 4 As shown, the method for merging routing domains according to this embodiment includes: step S402, determining at least two routing domains in the AS domain that need to be merged with routing domains; Determine the merged routing domain, and flood the following routing domain reset packets to routers in the predetermined merged routing domain, the routing domain reset packet specifies the merged route where the router interface in the AS domain is located domain; and step S406, the router receiving the routing domain reset data packet modifies the rout...

Abstract

The invention discloses a separating method of routing area, including: operation router used for cutting the routing area in the AS area, and supply the following routing area resetting data packet to the router of the routing area after being cut previously. The routing area resetting data packet indicates the routing area of the router pot in the AS area; and the router which receive the routing area resetting data packet modifies the routing area according to routing area resetting data packet. In addition, the invention discloses a combination method of routing area. Through the invention, the dynamic feedback network topological variation can be quickly realized and the utilization efficiency of the network resource can be increased, and artificial processing can be avoided, and thestability of the network can be strengthened.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method for dividing and merging routing domains. Background technique [0002] Currently, optical systems such as Optical transmission network (Optical transmission network, OTN), wavelength-division multiplexing (Wavelength-division multiplexing, WDM), synchronous digital hierarchy (Synchronous digital hierarchy, SDH), and synchronous optical network (Synchronous optical network, SONET) Networks have been widely used in the telecommunications field. [0003] Among them, ASON refers to a new generation of optical network that completes the automatic switching function under the control of routing and signaling, and has become a research hotspot in the field of optical network in recent years. The introduction of ASON technology can enhance the rapid configuration capability of network services, improve service survivability, effectively resist network multi-point fai...
