Problems solved by technology

This approach has significant limitations:
[0003] 1. The IP of at least one online node in the broadband communication network must be known. For many networks, the IP of the node connected to the management host must be known;
[0004] 2. Network topology scanning uses network layer and transport layer communication protocols, and has high requirements for network quality such as communication rate, communication delay and other indicators; it must be able to support network layer and transport layer communication protocols;
[0005] 3. The existing network topology scanning method takes a long time

Embodiment Construction

[0019] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0020] see figure 1 , the embodiment is, a broadband communication network topology scanning method, the data transmission in the scanning process is on the broadband communication network and based on data link layer protocol transmission, including the steps:

[0021] S1. The management host connects to any node in the topology network and sends a promise frame based on the data link layer protocol to a virtual address. When the promise frame is transmitted to the connected node, it is received by the connected node and no longer Forwarding, the accessed node responds to the agreed frame and sends a return frame with its own data link layer including MAC, IP, parent, and child node information to the management host, and the management h...

Abstract

The invention discloses a broadband communication network topology scanning method. In the scanning process, data are transmitted in a broadband communication network on the basis of a data link layer protocol, an agreed-on frame is sent to an agreed-on address through a management mainframe, the agreed-on frame is accepted when passing an access node and is not forwarded, the access node sends the information of the access node to the management mainframe so that the information of the access node can become known, and then the known information of the access node is used for completing topology scanning on a whole power line broadband communication network step by step. The broadband communication network topology scanning method has the advantages that a network layer protocol and a transport layer protocol do not need to be supported, and therefore restriction of an IP is gotten rid of; the scanning process can start under the condition that current network conditions are completely unknown; the requirements for channel quality and network communication capacity are lowered; the workload of frame separating and framing of all nodes is reduced, so that time for the network topology scanning is shortened.

Description

technical field [0001] The invention relates to the field of network topology scanning, in particular to a method for broadband communication network topology scanning. Background technique [0002] The network management of the current broadband communication network is basically based on IP. When the network topology is unknown and the management host of the broadband communication network needs to scan the network topology, it needs to use various IP-based protocols (such as SNMP) to obtain the parent and child node information of each node from some known nodes, and finally form the whole The topology of the network. This approach has significant limitations: [0003] 1. The IP of at least one online node in the broadband communication network must be known. For many networks, the IP of the node connected to the management host must be known; [0004] 2. Network topology scanning uses network layer and transport layer communication protocols, and has high requirements...
