Automatic control system for nucleonic product hydraulic pressure test using ZigBee wireless communication

Abstract

The present invention discloses a network node configuration information processing method in network topology generating variation. It contains A, network node according to network protocol monitoring whether other nodal state generating variation except oneself, if it is then executing B otherwise executing A; B, said network node modifying state varied node correspondent flag bit local polling list. The present invented processing method only needs simple modifying self preservation polling list to realize deleting sending fault nodal message in source node or restarting normal transmitting to said nodal message, if some node state generating variation. In this way, said invention avoids occupying nodal bulk processing ability to make modifying polling list operation, thereby indirectly raising node processing other task ability.

Description

Technical field [0001] The present invention relates to optical fiber communication technology, in particular to a processing method when the network topology changes. Background technique [0002] Resilient Packet Ring (RPR) technology integrates the intelligence of Internet Protocol (IP), the economy of Ethernet, and the high bandwidth efficiency and reliability of optical fiber ring networks, making it a broadband IP metropolitan area network The operator provides a good networking solution. A typical RPR network structure such as figure 1 Shown. Among them, A, B, C, and D are RPR nodes, and there are several terminals attached to each node. Since RPR networks are usually used in metropolitan area networks, the number of terminals connected to each node is very large. [0003] In order to provide terminal-to-terminal communication under different nodes, each node has two lookup tables: one is a mapping table between the destination terminal's Media Access Control (MAC) addres...

Problems solved by technology

At the same time, every time the faulty node recovers from the fault, other nodes except the faulty node need to re-determine the ring selection data to the faulty node, which requires additional operations to complete

In this way, the processing capacity of the nodes is always occupied by the task of comparing and modifying the query table entries, resulting in the weakening of the ability of the nodes to process other tasks; when the scale of the RPR network is further expanded, the nodes cannot meet the needs of practical applications.
