Embodiment 1

[0049] see image 3 , when the network scale is large, the entire network can be divided into several control and management domains. The division of control and management domains can be divided according to the specific situation, according to level, region, or a combination of level and region.

[0050] Since HSAPN adopts a hierarchical and orderly addressing method and hierarchical routing, a certain path can be determined according to the address, such as Figure 4 Shown is a schematic diagram of a hierarchical routing network. HSAPN addresses are addressed in a hierarchical manner according to operators and regions, so the addresses are hierarchical and orderly. For example, A.B.C.D is a form of HSAPN addresses. In this example, the network is divided into 4 levels, A, Sections B, C, and D (can also be divided into 5 sections and 6 sections according to the situation. The encoding format and length of each section can be set according to the situation. It is recommended ...

Embodiment approach

[0064] As another implementation manner, the above-mentioned control management device includes:

[0065] An information collection module, configured to collect link state advertisement information sent by routers within the jurisdiction;

[0066] The area network topology map generation module is used to generate the network topology map of the area under the jurisdiction of the control device according to the received link state notification information of the area under its jurisdiction;

[0067] The second synchronization module is used to synchronize information between the generated network topology diagram of the jurisdiction area of ​​the control device and the network topology diagrams of the jurisdiction regions of other domain control and management devices, so as to obtain the network topology diagram of the entire network.

[0068] The above-mentioned control and management equipment may also include:

[0069] The intercommunication module is configured to notif...

Embodiment 2

[0076] After the control and management equipment is deployed, each domain is under the control and management of the CMD of the domain, and the network topology diagram is established through the information synchronization between the CMDs, such as Figure 8 As shown, taking the HSAPN network as an example, the embodiment of the present invention provides a method for obtaining a network topology map of a sub-area network, and the steps are as follows:

[0077] Step 201: Each domain establishes a control management channel network between the CMD and each HSAPN router in the area under the jurisdiction of the CMD.

[0078] The embodiment of the present invention provides the following two technical solutions to realize the establishment of the control management channel network between the CMD and each HSAPN router in the area under its jurisdiction:

[0079] 1. Establish an in-band control management channel network

[0080] Before the entire network starts running, a rout...

Abstract

The invention discloses a domain split network and a method for obtaining a network topology map of the domain split network, belonging to the technical field of packet data networks. The network comprises at least two control management domains, wherein each control management domain comprises at least one router and at least one control management device; a control management channel is established between the router in each control management domain and the control management device dominating the router; and full connection and information synchronization are carried out between each two control management devices. The method comprises the following steps: the control management device of each domain respectively collects link state advertisement information sent by the router in the administering domain; synchronization is carried out on the collected link state advertisement information of the administering domain among the control management device of every domain to obtain the link state advertisement information of a whole network; and the network topology map of the whole network is calculated according to the link state advertisement information of the whole network. The invention realizes load share of each control management device and reliable guarantee after single-point failure.

Description

technical field [0001] The invention relates to the technical field of packet data networks, in particular to a domain-divided network and a method for obtaining a network topology diagram of the domain-divided network. Background technique [0002] With the development of technology, the telecommunication network has successfully completed the transition from analog technology to digital technology, and is undergoing the transition from TDM (Time-Division Multiplexing) technology to packet switching technology, ATM (Asynchronous Transfer Mode , Asynchronous Transfer Mode) packet technology is a representative of this transition, but due to technical difficulties and unsuccessful commercial operations, the second transition of the telecom network has not been realized. In the early 1990s, the Internet based on IP (IP Protocol) packet technology achieved great success due to the application of Web technology. extend. Therefore, the telecommunication network has introduced I...
