Message processing method and device

Abstract

Embodiments of the present invention provide a message processing method and device. The method includes: the first node generates a first message according to the first data of the first node, the first message includes a message header, and the message header includes a service type, a final destination address and a remaining aggregation number RTA. When the RTA of the first message is not 0, the first node determines the remaining capacity in the first buffer corresponding to the service type and the final destination address, and the second message is stored in the first buffer. When the data length of the first message is not greater than the remaining capacity, the first node aggregates the first message and the second message into a third message, and the message header of the third message includes the RTA of the third message , the RTA of the third message is the minimum value between the RTA of the first message minus 1 and the RTA of the second message. By aggregating packets with the same service type and destination address, it solves the problem that uplink packets occupy a large amount of network bandwidth and affect the normal operation of services.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a message processing method and device. Background technique [0002] With the development of wireless personal area network (Wireless Personal Area Network, WPAN) technology, wireless mesh network (mesh) network and mobile ad hoc network (Ad Hoc) based on this type of technology for multi-hop extension are widely used. In the topological structures formed by these two networks, a tree structure usually appears, that is, a node in the network is connected to multiple child nodes, and some of the child nodes are connected to multiple child nodes. In a tree network, nodes have clear uplink and downlink communication directions. Uplink is to send data from a child node to its common parent node, and downlink is to send data from a parent node to one of its child nodes. For example, if figure 1 As shown in the tree structure in , when any one or more nodes fr...
