Abstract
The invention discloses an industrial Ethernet switch redundancy loop technology. The technology is characterized in that Ethernet switches are connected end to end by a link to form a redundancy loop network, a master switch and a plurality of slave switches are randomly arranged in a network management system, an active link and a standby link are dynamically selected on the master switch, and the network is pruned to a loop-free topological structure; when the structure of the network is changed, the network management system resets the master switch according to the state of the network, the slave switch becoming the master switch reserves new network configuration, the original master switch is degraded into a slave switch, and simultaneously, the active link and the standby link are reselected; when the active link fails, the switch changes the port state, and switches the standby link into the active link. When the technology is used, data is stably transmitted by limiting data forwarding of a specific port; and when the communication link fails and the structure of the network is changed, the technology ensures that the network is instantaneously recovered within 0-15ms.
Description
Technical field
The present invention relates to the network communications technology, specifically a kind of industrial ethernet switch redundancy loop technique.
Background technology
In a LAN built by multiple stage industrial ethernet switch, in order to strengthen the reliability of Transmission system,
The path of a redundancy must be set up, but simple road Jing loopbacks are fatal for a LAN.It can bring as
Lower problem：Broadcast storm, the multiple copies of same frame, unstable mac address table etc., therefore must have one in exchange network
Individual mechanism is preventing loop.
The content of the invention
The invention aims to make up the defect of prior art, there is provided a kind of industrial ethernet switch redundancy loop skill
Art.
The present invention is achieved by the following technical solutions：
A kind of industrial ethernet switch redundancy loop technique, it is characterised in that：Pass through link head and the tail phase between Ethernet switch
Even composition redundant looped network, a host exchange and multiple stage are arbitrarily arranged from switch by network management system, are moved on host exchange
State selects active link and reserve link, is loop-free topological structure by network cut, when network structure changes, webmaster
System will reset host exchange according to network state, and become host exchange retains new network configuration from switch, former
Host exchange is reduced to from switch, while reselecting active link and reserve link, when active link breaks down, is exchanged
Machine changes port status, and cut-in stand-by link is active link.
A kind of described industrial ethernet switch redundancy loop technique, it is characterised in that：The switch system has system
One mac address table.
It is an advantage of the invention that：The present invention takes full advantage of the transmission characteristic of Ethernet data, is assisted by specific data
View, quickly timely data transfer, reaches the redundancy mechanism communication of the whole network inter-exchange.When using, in real network cyclization even
In the case of connecing, by the data forwarding for limiting particular port, so as to reach the stable transmission of data.When event occurs in communication link
Barrier, when network structure changes, network state will be reconfigured, and be added at the mac address table of total exchange machine systematic unity
Reason, ensures that network momentary recovery in 0-15ms, greatly meets industrial scale applications and reliability and real-time are wanted
Ask.
Description of the drawings
Fig. 1 is the switch-link figure of the present invention.
Specific embodiment
Technical scheme is described further below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of industrial ethernet switch redundancy loop technique of the present invention, it is characterised in that：Ether
Joined end to end composition redundant looped network by link 2 between network switch 1, by network management system arbitrarily arrange a host exchange and
From switch, network cut is loop-free topology to multiple stage by dynamic select active link and reserve link on host exchange
Structure, when network structure changes, network management system will reset host exchange according to network state, become host exchange
Retain new network configuration from switch, former host exchange is reduced to from switch, while reselecting active link and standby chain
Road, when active link breaks down, switch changes port status, and cut-in stand-by link is active link.
A kind of described industrial ethernet switch redundancy loop technique, it is characterised in that：The switch system has system
One mac address table.
Specific embodiment described herein be only to explanation for example of the invention, the technical field of the invention
Technical staff can be made various modifications to described specific embodiment or supplement or substituted using similar mode, all
Should cover within the protection domain of invention.
