Embodiment Construction

[0027] Embodiments of the present invention will now be described with reference to the drawings.

[0028] The topology of a "network of resource-constrained devices" may be any mesh topology, such as Figure 4 As shown, the network topology contains closed loops (401, 402). However, in most cases, the "network of resource-constrained devices" has a tree topology, such as Figure 5 shown. If the "network composed of resource-limited devices" topology contains closed loops, a known method such as "spanning tree" (IEEE802.1d) can be used to form a tree topology without closed loops.

[0029] The present invention performs topology discovery and configuration management between devices only through link layer protocol message exchange. Among them, "source path backtracking" is used to discover topology, while "virtual management path" is used for configuration management. Both related query and response messages are link layer messages. If the physical link is Ethernet, the ...

Abstract

A method for managing the network composed of the devices with limited resource includes such steps as determining that said network is a tree network, performing link-layer protocol message interaction between devices to find out network topology, obtain network topology information and constructing network topology data information, and choosing a device according said data information for configure management.

Description

technical field [0001] The invention relates to a network management method, in particular to a network management method for managing a network composed of resource-limited devices. Background technique [0002] With the development of technology, data communication equipment is more and more widely used in communication operations, industrial control, household consumption and other fields, and some special requirements are put forward. One of the most important requirements is: how to provide a simple, practical and low-cost device management method for a network composed of resource-constrained devices. Especially in customer premises network, intelligent network appliances and network-based distributed control system, the demand is particularly urgent. For example, the corridor switches in the customer premises network, the smart sensors in the distributed control system, and the smart home appliances in the smart home all need to be managed centrally through the netwo...
