Method for transmission using Mbus communication middle ware

Abstract

This invention puts for ward a method for utilizing M bus communication intermediate unit for transmission including the following steps: A delivering M bus order at the applying layer of the delivery party, B The construction layer packages the M bus order and assigned target address to be delivered by the user in a specific kind of messages, C encoding the message to byte stream at the coding layer to transmit it to the server by TCP protocol, D The byte stream is decoded at the server to address according to the message target address them to encode and send it to a matched receiver, E The receiver decodes it again and delivers the extracted M bus order to the applying.

Description

technical field [0001] The present invention relates to a method for using middleware for transmission, in particular to a method for using Mbus (The Message Bus) lightweight inter-component communication middleware for transmission. Background technique [0002] J.Ott, C.Perkins and D.Kutscher proposed the Local Coordination Message Bus (A Message Bus for Local Coordination) in RFC 3259 published in April 2002, which is a light-load, oriented Message communication coordination protocol. This protocol proposes a good address notation and addressing strategy, and the typical application fields are local conference control and communication of device groups in the LAN. It provides a simple and flexible message communication channel for components on one or more hosts in the local area network. It has the characteristics of peer-to-peer positioning, point-to-point communication, group communication and security assurance. Fields such as networked pervasive computing environme...

However, its transmission mechanism does not support coordinated control over a wide area network: since the message is sent to all local objects using local multicast, each entity must receive and distinguish the message whether it needs it or not. In this way, when the number of local entities and the number of messages sent are large, the system efficiency will be significantly reduced; it achieves reliable transmission through a simple timeout retransmission strategy, which is relatively effective in the local area network, but due to the uncertainty of Internet transmission delay, This non-adaptive method does not guarantee accurate and reliable semantics when communicating with remote nodes across LAN boundaries; since entity awareness, state maintenance, and message transmission all rely on multicast at the transport layer, not all All routers support multicast, which further limits its application
