The forwarding of net packet specifically includes: a port of slave receives BPDU packet and then forwards non-BPDU packet in another port, and slave exists
A port receives non-BPDU packet and then forwards BPDU packet in another port, and the packet of the same sequence number only forwards once.
6. a kind of industrial ethernet switch looped network according to claim 1 quickly solves network method, which is characterized in that described
In looped network interchanger slave become host satisfaction condition include:
A. port status of the slave in looped network changes, and specifically includes: the port becomes dual link from single-stranded line state
State or the port become single-stranded line state from double-strand line state；
B. the protocol massages packet MAC Address received when the slave that port status is in single-stranded line state is smaller than own MAC address,
The slave is converted to host at once；
The slave that the address C.MAC maximum mark is 1 receives that port status is dual link and two ports are connection status
Looped network packet, the slave become host, and the identical packet of looped network packet Status Flag sent and received.
7. a kind of industrial ethernet switch looped network according to claim 5 quickly solves network method, which is characterized in that described
Host in looped network includes the port for being in blocked state, and the host sends non-BPDU packet and BPDU packet simultaneously,
Whether the non-BPDU packet and BPDU packet packet number having the same, host port blocked do not change, needing when giving out a contract for a project
Want aging mark position 0；Host port blocked changes, whether needing aging home position 1, and one ground of band when giving out a contract for a project
Location aging ID, each state change of aging ID are both needed to add 1, if aging ID is 0, need to add 2.
8. a kind of industrial ethernet switch realizes the system that looped network quickly solves net, which is characterized in that the system includes: storage
Device, processor include quickly solving network method program, the industry ether with industrial ethernet switch looped network in the memory
Network switch looped network quickly solves when network method program is executed by the processor and realizes following steps:
Identical state is set by the corresponding ports of each interchanger in looped network and looped network mark, loop network link powers on, each to hand over
It changes planes and sends looped network packet to the interchanger connecting with itself as host；
Each interchanger is respectively by the looped network packet MAC Address received compared with the MAC Address of itself in the looped network；
When the looped network packet MAC Address that interchanger receives is bigger than the MAC Address of itself, then current SWITCH Status Change be from
Machine is simultaneously stopped and sends looped network packet, and current SWITCH supports two ports of looped network to be in opening state, and forwards communication number
According to change oneself state is also slave by the data message that other interchangers receive current SWITCH in the looped network, described
The port of each slave in looped network in addition to host is in an open state, to realize the quick solution net of looped network.
9. the system that a kind of industrial ethernet switch looped network according to claim 8 quickly solves net, which is characterized in that will
The port of each interchanger in looped network is set as identical state, specifically includes: by the interchanger in looped network according to MAC Address
Size sequence, each interchanger that the loop network link connection is set in loop after powering on is host, i.e., each interchanger all assumes that
It itself is the maximum interchanger of MAC Address in the looped network of place, concurrently set each interchanger has a port obstruction, an end
Mouth is opened.
10. a kind of computer readable storage medium, which is characterized in that include industrial ether in the computer readable storage medium
Network switch looped network quickly solves network method program, and the industrial ethernet switch looped network quickly solves network method program by processor
When execution, realize that the industrial ethernet switch looped network as described in any one of claims 1 to 7 quickly solves the step of network method
Suddenly.
