Embodiment

[0040] In the embodiment of the present invention, it is first necessary to establish an RMAC layer that can provide all management and data access interfaces supported by the MAC for the upper layer software between the upper layer software of the coordinator and the MAC layer, and two physical MACs are attached under the RMAC layer, for For the convenience of description, they are marked as MAC-0 and MAC-1 respectively. MAC-0 and MAC-1 are respectively linked to the physical network cards PHY-0 and PHY-1. These two physical MACs work in non-promiscuous mode and have The same MAC address is recorded as mac, and the software and hardware hierarchy of the coordinator established by the above method is as follows: figure 1 shown;

[0041] Before the MAC client works normally, it must be initialized, that is, the RMAC layer tests whether the sending and receiving functions of the two physical MACs are normal. If it is abnormal, it will report to the system, indicating that the RM...

Abstract

The invention relates to a wireless private area network communication technology, and discloses a backup method for a coordinator of a wireless private area network, which solves the problem of long network convergence time caused by a traditional backup method. The key points of the technical scheme can be summarized as follows: a strong MAC (media access control) layer is built between an MAC customer and an MAC layer; a main MAC and at least one standby MAC are cascaded below the strong MAC layer; the failure times for message transmission and the times for receiving the messages of the main MAC are counted, and the counting result is timely detected, then a decision of whether to implement master-slave switching or not is carried out according to the counting result. Besides, the invention also discloses the coordinator of the wireless private area network. The invention provides reliable and fault tolerant MAC service for upper layer software through multiple physical MACs, does not need to remotely backup network nodes, and leads other node devices in the network to not need to sense the existence of standby nodes through the backup of a local interface. Moreover, mass data synchronization can not be involved, and the network convergence time is reduced. The backup method for the coordinator of the wireless private area network is applicable to wireless private area network communications.

Description

technical field [0001] The invention relates to a wireless personal area network communication technology, in particular to a backup method and device for a wireless personal area network coordinator. Background technique [0002] WPAN (Wireless Personal Area Network) is a wireless communication technology with a shorter communication distance than WLAN. The current mainstream WPANs are all based on the underlying technologies defined by the IEEE802.15 working group, such as Bluetooth, WiMedia, and Zigbee, respectively corresponding to the corresponding standards defined by IEEE802.15.1, IEEE802.15.3, and IEEE802.15.4. [0003] The PAN coordinator is the most important node in the WPAN, responsible for the management, security and interconnection with other networks of the entire network. Once the wireless link of the PAN coordinator fails, the entire WPAN will be paralyzed. Therefore, in order to ensure the reliability of wireless communication, it is necessary to back up...
