Embodiment Construction

[0056] Now, the present invention will be described in further detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention, and should not be construed as limiting the present invention.

[0057] Such as figure 1 Shown, the mutual conversion method of SNMP message of the present invention and CoAP message, by figure 2 The SNMP / CoAP adapter in the SNMP / CoAP adapter is converted, and the protocol conversion module in the SNMP / CoAP adapter is converted through the following steps:

[0058] S100. Map Get and GetNext operations in SNMP to Get operations in CoAP;

[0059] S200. Mapping the Trap mechanism in SNMP to the subscription mechanism in CoAP;

[0060] S300. judge whether the Set operation among the SNMP is the operation of revising the general field, if so,...

Abstract

The invention discloses a message conversion method based on SNMP and CoAP. Mutual conversion of an SNMP message and a CoAP message can be realized by use of an SNMP / CoAP adapter. The invention also discloses a wireless controller that comprises the SNMP / CoAP adapter for converting an SNMP request message sent by an SNMP proxy module into a CoAP request message, converting a CoAP response message of a CoAP service module into an SNMP response message and converting a push message of a wireless sensing node received by the CoAP service module into a Trap message of SNMP. According to the message conversion method, due to the mutual conversion of SNMP and CoAP, an SNMP manager is enabled to manage Internet-of-Things equipment based on a CoAP protocol by use of the wireless controller; an SNMP protocol can be effectively supported and efficient SNMP Internet-of-Things network management can be realized without replacing the sensing node.

Description

technical field [0001] The invention relates to a message conversion method based on SNMP and CoAP, a wireless controller and a network management system. Background technique [0002] In recent years, low-rate wireless personal area network (LR-WPAN) technology that integrates network technology, embedded technology and sensor technology has become a research hotspot. LR-WPAN is a network designed for short-distance, low-speed and low-power wireless communication, and can be widely used in fields such as smart home appliances and industrial control. Network management technology is critical to LR-WPAN networks. Due to the large scale of the network, and the location of some equipment cannot be reached by personnel, the LR-WPAN network should have self-healing ability, and the network management technology of LR-WPAN is required to be able to manage highly densely distributed networks with very low overhead. equipment. Since the forwarding of IPv6 data on IEEE802.15.4 adv...
