Specific embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work Embodiment, broadly falls into the scope of protection of the invention.

Multiple network equipments in network can be after the ring structure being connected as a closure, by configuring identical ring ID One looped network of composition, there may be multiple looped networks, one of network equipment may reside in multiple looped networks in network.Due to It is only capable of at present by manually being configured in web page or by Command Line Interface (Command-Line Interface, CLI) Method be looped network in each network equipments configuration ring ID, less efficient and error-prone.Therefore the embodiment of the present invention provides one kind Ring ID generation method and network, realize automatically generating of ring ID, very high and not using the ring ID configuration ring ID efficiency automatically generating Mistake can be produced.

Ring network structure is divided into monocyclic and polycyclic two kinds of situations, wherein monocyclic refers to that each network equipment exists only in a ring In net, polycyclic refer at least one network equipment be located at plural looped network in.The embodiment of the present invention will be respectively directed to monocyclic With polycyclic two kinds of different situations, ring ID generation method provided in an embodiment of the present invention is described in detail.

Fig. 1 is the flow chart of ring ID generation method embodiment one provided in an embodiment of the present invention, as shown in figure 1, this enforcement The ring ID generation method that example provides includes：

Step S101, when on the first network equipment that at least one port is in connection status, is not in connection status The state of first port when being changed into connection status, then first network equipment sends the first ring detecting message, the first ring detecting report Literary composition be medium access control (Media Access Control, MAC) frame message, first ring detect message source MAC and Target MAC (Media Access Control) address is the MAC Address of first network equipment.

The ring ID generation method that the present embodiment provides is applied in the looped network of single ring architecture, forms in monocyclic looped network at least Including two network equipments.After the network equipment is connected with each other, just can carry out the transmission of message, between the network equipment Connection can be physical connection or wireless connection, in a word, establish and can carry out between the network equipment after connection The physical communication link of data transfer.As long as can carry out between the network equipment being connected MAC layer message send and Receive.

It is attached by different physical communication ports between the network equipment, and the network equipment can detect port It has been in connection status.For any one of network network equipment, it is referred to as first network equipment, if first network equipment It is connected with other network equipments in network by least one port, now first network equipment is not to except The state of the port connecting is detected, detects whether to be in the port of connection status.

If first network equipment is changed into connection status still not at any one port of connection status, this port is referred to as Single port, then first network equipment start to send the first ring detecting message.First ring detecting message is mac frame message, the first ring Detecting message starts back-propagation successively from the port sending, and is in the network equipment of same double layer network with first network equipment The first ring detecting message will be received, the first ring detects the source MAC of message and target MAC (Media Access Control) address is all configured to first network The MAC Address of equipment.The destination address that i.e. the first ring detects message is first network equipment itself.First ring detecting message is one Plant special message, its purpose is exactly the state in order to detect looped network, and realizes the calculating of ring ID.

Step S102, each receives second network equipment transmission the second ring detecting message that the first ring detects message, the Two ring detecting messages are mac frame message, and the second ring detects the source MAC of message and target MAC (Media Access Control) address is transmission the second ring The MAC Address of second network equipment of detecting message.

The network equipment receiving the first ring detecting message is referred to as second network equipment, second network equipment is receiving First ring detecting message after, a special message will be sent, be referred to as second ring detecting message, second ring detecting message with The structure that first ring detects message is identical, is similarly mac frame message.Second ring detects source MAC and the purpose MAC ground of message Location is the MAC Address sending second network equipment that the second ring detects message.First ring detecting message and the second ring detecting report Literary composition is a kind of similar message, wherein need not carry data, simply all configure the source MAC of message and target MAC (Media Access Control) address For sending the MAC Address of the network equipment of this message.The trigger mechanism that first ring detects message is that the network equipment detects Port outside the port of connection status is changed into sending during connection status, and the trigger mechanism that the second ring detects message is to receive it Send during the first ring detecting message that his network equipment sends.In fact, it is that the network equipment cannot be distinguished by the message that receives One ring detecting message or the second ring detecting message, as long as after the network equipment receives mac frame message, find the source of this message MAC Address is identical with target MAC (Media Access Control) address, and just triggering sends the second ring detecting message that is to say, that the network equipment receives other Transmission the second ring detecting message equally can be triggered after the second ring detecting message that the network equipment sends.Report with sending the second ring detecting The network equipment of literary composition the is located at same double layer network network equipment after connecting can receive the second ring detecting message.

Step S103, first network equipment, after receiving the first ring detecting message, is detected in message according to the first ring MAC Address detects the MAC Address in message with each second ring receiving, and calculates the first ring ID according to preset algorithm, the One ring ID is including first network equipment and each second ring detecting message each the second network equipment group corresponding receiving The ID of the looped network becoming.

Often connect a new network equipment in a network, the new network equipment connecting all will set as new first network Standby, all can trigger execution step S101 and step S102.After the network equipment is connected with each other the ring structure becoming a closure, right In any one of network network equipment, all source MAC will be received and target MAC (Media Access Control) address is the MAC of own MAC address Frame message.This is because the ring structure of closure can make the forwarding by multiple network equipments for the mac frame message that the network equipment sends Central link along closure is transmitted to itself.

Still, if first network equipment receives source MAC and target MAC (Media Access Control) address is taking first network equipment as a example The message of the MAC Address of one network equipment, i.e. the first ring detecting message, then first network equipment can perceive network Cyclization.First network equipment can carry out the calculating of ring ID.Because the network equipment of each new access network is when accessing looped network, At least need two ports to be attached from the different network equipments respectively, then the network equipment in looped network is at least carried out Cross the process of step S101, be at least transmitted across a source MAC and target MAC (Media Access Control) address is the MAC of the MAC Address of itself Frame message, then for first network equipment, the mac frame message that in looped network, each network equipment sends will be received.First net Network equipment can calculate the first ring ID according to the MAC Address of the all-network equipment in looped network, that is, according to receive each the The MAC Address of the MAC Address in two rings detecting messages and first network equipment calculates the first ring ID.

First network equipment can use any one algorithm, calculates the first ring ID according to multiple MAC Address.

Step S104, each second network equipment receive itself transmission second ring detecting message after, according to first Ring detects the MAC Address in message, the MAC Address in the second ring detecting message of itself transmission and other second nets receiving The second ring that network equipment sends detects the MAC Address in message, calculates the first ring ID according to preset algorithm.

Group cyclization ID is in the looped network of the first ring ID, except first network equipment, also has multiple other second networks Equipment, when network cyclization, other each second network equipments also will receive the second ring detecting message of itself transmission, simultaneously Second network equipment also will receive the mac frame message that in looped network, each network equipment sends, that is, can obtain in looped network Each network equipment MAC Address.So second network equipment can be according to other network equipments in the message receiving MAC Address and the MAC Address of itself calculate the first ring ID.Second network equipment adopts and first network equipment identical algorithm meter Calculate the first ring ID.Because first network equipment and second network equipment are all the MAC Address according to all-network equipment in looped network Calculate the first ring ID, and employ identical algorithm, the first ring ID that each network equipment therefore in looped network calculates It is identical.

Any one of looped network network equipment all calculates after the first ring ID according to identical method, you can by the ring of itself ID is configured to the first ring ID, so that the network equipment carries out message transmissions in ring according to the first ring ID.First network equipment and each Second network equipment can carry out the calculating of the first ring ID simultaneously, and that is, step S103 and step S104 can be carried out simultaneously.

The ring ID generation method that the present embodiment provides, when at least one port is in the first network equipment of connection status On, when being not in the state of the first port of connection status and being changed into connection status, send the first ring detecting report based on mac frame Literary composition, the first ring detects the source MAC of message and target MAC (Media Access Control) address is the MAC Address of first network equipment, and each receives First ring detects the second network equipment transmission source MAC of message and target MAC (Media Access Control) address is the second ring of own MAC address Detect message so that each network equipment in network all knows the MAC Address of other network equipments, when first network equipment receives To after the first ring detecting message itself sending, or second network equipment receives the second ring detecting message of itself transmission Afterwards, all can perceive network cyclization, and the MAC Address according to all-network equipment in looped network calculates ring ID it is achieved that ring respectively Automatically generating of net middle ring ID, improves the efficiency of ring ID configuration, is not likely to produce mistake simultaneously.

Further, in the embodiment shown in fig. 1, after step S102, that is, when receive that the first ring detects message the After two network equipments send the second ring detecting message, second network equipment can also start first timer.First timer There is a Preset Time, after starting first timer, before the Preset Time time-out of first timer, this receives the first ring Second network equipment of detecting message does not retransmit the second ring detecting message.Namely when second network equipment sends one time second After ring detecting message, do not retransmit the second ring detecting message within a period of time, even if second network equipment receives the again One ring detecting message or the second ring detecting message, as long as first timer has not timed out, second network equipment does not retransmit second yet Ring detects message.When the network equipment quantity that connects in a network is more, second network equipment in addition to the first ring detects message, It is also possible to receive the second ring detecting message of other network equipments transmission.If second network equipment receives the first ring detecting report After the second ring detecting message that literary composition and other network equipments send, all send the second ring detecting message, the in network can be led to Two ring detecting message amount are excessive, thus taking the excessive network bandwidth.Therefore, send the second ring detecting in second network equipment After message, first timer being started, before first timer time-out, not sending the second ring detecting message again, thus saving The about network bandwidth.

It should be noted that the timing of first timer can not arrange long it is impossible to make second network equipment exist Receive newly connect access network the network equipment send first ring detecting message when, still can not send second ring detecting message. In addition, first network equipment is sending it is also possible to start first timer after the first ring detects message, in first timer time-out Front no longer send the message that source MAC and target MAC (Media Access Control) address are own MAC address.

Further, in the embodiment shown in fig. 1, first network equipment specifically can be in being in beyond first port The port of connection status sends the first ring detecting message.The trigger condition that first network equipment sends the first ring detecting message is first First there is the port being in connection status, then detect again and be in the first port of not-connected status and become connection status. First port is the equal of the latter linked port of first network equipment.So that is, first network equipment detects first After port is changed into connection status, it is not to send the first ring detecting message in the new first port connecting, but connects before The port connecing sends.Because each network equipment eventually forms the ring network structure of a closure, after composition looped network, each network Equipment can detect message by the first ring that the loop configuration of looped network receives the transmission of other network equipments or the second ring is detectd Observe and predict literary composition, therefore, the network equipment, when sending the first ring detecting message, only need to be sent by the port of a connection, The quantity sending message in network so can be reduced.Similarly, receive second network equipment that the first ring detects message Only the second ring detecting message can be sent in the port receiving the first ring detecting message.

Embodiment illustrated in fig. 1 shows in the case of monocyclic, ring ID generation method provided in an embodiment of the present invention.Below again Taking polycyclic situation as a example, ring ID generation method provided in an embodiment of the present invention is illustrated.

Fig. 2 is the flow chart of ring ID generation method embodiment two provided in an embodiment of the present invention, as shown in Fig. 2 this enforcement The ring ID generation method that example provides includes：

Step S201, when on the first network equipment that at least one port is in connection status, is not in connection status The state of first port when being changed into connection status, then first network equipment sends the first ring detecting message, the first ring detecting report Literary composition is mac frame message, and the first ring detects the source MAC of message and target MAC (Media Access Control) address is the MAC ground of first network equipment Location.

Step S202, each receives second network equipment transmission the second ring detecting message that the first ring detects message, the Two ring detecting messages are mac frame message, and the second ring detects the source MAC of message and target MAC (Media Access Control) address is transmission the second ring The MAC Address of second network equipment of detecting message.

Step S203, first network equipment, after receiving the first ring detecting message, is detected in message according to the first ring MAC Address detects the MAC Address in message with each second ring receiving, and calculates the first ring ID according to preset algorithm, the One ring ID is including first network equipment and each second ring detecting message each the second network equipment group corresponding receiving The ID of the looped network becoming.

Step S204, each second network equipment receive itself transmission second ring detecting message after, according to first Ring detects the MAC Address in message, the MAC Address in the second ring detecting message of itself transmission and other second nets receiving The second ring that network equipment sends detects the MAC Address in message, calculates the first ring ID according to preset algorithm.

Step S201 is similar to step S104 with step S101 in embodiment illustrated in fig. 1 to step S2044, that is, in net Set up a looped network in network, and generate the process of ring ID.After having established a looped network in network, resettle new looped network When, if there is no the network equipment sharing in new looped network and the looped network of foundation, then newly looped network set up process and ring ID Generation method can be carried out according to embodiment illustrated in fig. 1.If there is at least one altogether in new looped network and the looped network of foundation The network equipment, then continue executing with the follow-up process in the present embodiment.

Step S205, if the first port of first network equipment and receive outside the port that the first ring detects message, the One network equipment still has at least one to be in the port of connection status, then when first network equipment is in the of not-connected status When Two-port netwerk is changed into connection status, first network equipment is sent out with the port receiving outside the first ring detects message in first port Send the 3rd ring detecting message, the 3rd ring detects the source MAC of message and target MAC (Media Access Control) address is the MAC of first network equipment Address.

Still so that the shared network equipment in new looped network with the looped network of foundation is for first network equipment as a example.If the first net Network equipment has been positioned in the looped network that ring ID is the first ring ID, then the first port of first network equipment is sent out with receiving oneself The port of the first ring detecting message sending broadly falls into the port of the looped network that ring ID is the first ring ID.First network equipment is then connected to When in other looped networks, also it is only capable of using other ports.So first network equipment needs except the first of first network equipment Port and receiving outside the port that the first ring detects message, still has at least one to be in the port of connection status, subsequently examines Survey the port that other are in not-connected status, if first network equipment is changed into connecting still not at any one port of connection status State, this port is referred to as second port, then first network equipment starts to send the 3rd ring detecting message.First network equipment is only Can first port and receive first ring detect message port outside port send the 3rd ring detecting message, this be due to First port already belongs in the looped network that ring ID is the first ring ID it is impossible to add new with the port receiving the first ring detecting message Looped network, lead to ring ID to calculate in order to avoid the network equipment in the looped network of foundation receives the 3rd ring detecting message wrong By mistake, therefore the 3rd ring detecting message can not be sent in above-mentioned port.

3rd ring detecting message is mac frame message, and the 3rd ring detects the source MAC of message and target MAC (Media Access Control) address is all joined It is set to the MAC Address of first network equipment.The destination address that i.e. the 3rd ring detects message is first network equipment itself.With first The network equipment the is located at same double layer network network equipment after connecting can receive the 3rd ring detecting message.3rd ring detecting Message is identical with the first ring detecting message, and its purpose is also for the state of detecting looped network, and realizes the calculating of ring ID.

Step S206, each receives the 3rd network equipment transmission Fourth Ring detecting message that the 3rd ring detects message, the Fourth Ring detecting message is mac frame message, and the source MAC of message is detected at Fourth Ring and target MAC (Media Access Control) address is transmission Fourth Ring The MAC Address of the 3rd network equipment of detecting message.

The 3rd network equipment receiving the 3rd ring detecting message will send a special message, is referred to as Fourth Ring Detecting message, the structure that message is detected at Fourth Ring with the 3rd ring detects message is identical, is similarly mac frame message.Fourth Ring is detected The source MAC of message and target MAC (Media Access Control) address are the MAC Address sending the 3rd network equipment that message is detected at Fourth Ring.The Three ring detecting messages are a kind of similar messages with Fourth Ring detecting message, wherein need not carry data, simply by the source of message MAC Address and target MAC (Media Access Control) address are each configured to send the MAC Address of the 3rd network equipment of this message.3rd ring detecting message Trigger mechanism be the network equipment detect first port and receive first ring detect message port outside, connected shape Port outside the port of state is changed into sending during connection status；The trigger mechanism that message is detected at Fourth Ring is to receive other networks Send during the 3rd ring detecting message that equipment sends.In fact, the message that the network equipment cannot be distinguished by receiving is detectd for the 3rd ring Observe and predict literary composition or Fourth Ring detecting message, as long as after the network equipment receives mac frame message, finding the source MAC of this message Identical with target MAC (Media Access Control) address, just triggering sends Fourth Ring detecting message that is to say, that the 3rd network equipment receives other nets Transmission Fourth Ring detecting message equally can be triggered after the Fourth Ring detecting message that network equipment sends.Detect message with sending Fourth Ring The network equipment connect after be located at same double layer network the network equipment can receive Fourth Ring detecting message.

Step S207, first network equipment, after receiving the 3rd ring detecting message, is detected in message according to the 3rd ring MAC Address detects the MAC Address in message with each Fourth Ring receiving, and calculates the second ring ID according to preset algorithm, the Two ring ID are including first network equipment and each Fourth Ring detecting message each the 3rd network equipment group corresponding receiving The ID of the looped network becoming.

Often be connected a new network equipment in a network with first network equipment, the new network equipment connecting all using as New first network equipment, all can trigger execution step S205 and step S206.Become one and close when the network equipment is connected with each other After the ring structure closing, for any one of network network equipment, all will receive source MAC and target MAC (Media Access Control) address will be The mac frame message of own MAC address.This is because the ring structure of closure can make the mac frame message of network equipment transmission by many The central link along closure that forwards of the individual network equipment is transmitted to itself.

Still, if first network equipment receives source MAC and target MAC (Media Access Control) address is taking first network equipment as a example The message of the MAC Address of one network equipment, i.e. the 3rd ring detecting message, then first network equipment can perceive network Cyclization.First network equipment can carry out the calculating of ring ID.Because the network equipment of each new access network is when accessing looped network, At least need two ports to be attached from the different network equipments respectively, then the network equipment in looped network is at least carried out Cross the process of step S205, be at least transmitted across a source MAC and target MAC (Media Access Control) address be own MAC address MAC Frame message, then for first network equipment, the mac frame message that in looped network, each network equipment sends will be received.First net Network equipment can calculate the second ring ID according to the MAC Address of the all-network equipment in looped network, that is, according to receive each the The MAC Address of the MAC Address in Fourth Ring detecting message and first network equipment calculates the second ring ID.

First network equipment can use any one algorithm, calculates the second ring ID according to multiple MAC Address.

Step S208, each the 3rd network equipment receive itself transmission Fourth Ring detecting message after, according to the 3rd Ring detects the MAC Address in message, the MAC Address in the Fourth Ring detecting message of itself transmission and other the 3rd nets receiving The MAC Address in message is detected at the Fourth Ring that network equipment sends, and calculates the second ring ID according to preset algorithm.

Group cyclization ID is in the looped network of the second ring ID, except first network equipment, also has multiple other 3rd networks Equipment, when network cyclization, other each 3rd network equipments also will receive the Fourth Ring detecting message of itself transmission, simultaneously 3rd network equipment also will receive the mac frame message that in looped network, each network equipment sends, that is, can obtain in looped network Each network equipment MAC Address.So the 3rd network equipment can be according to other network equipments in the message receiving MAC Address and the MAC Address of itself calculate the second ring ID.3rd network equipment adopts and first network equipment identical algorithm meter Calculate the second ring ID.Because first network equipment and the 3rd network equipment are all the MAC Address according to all-network equipment in looped network Calculate the second ring ID, and employ identical algorithm, the second ring ID that each network equipment therefore in looped network calculates It is identical.

Any one of looped network network equipment all calculates after the second ring ID according to identical method, you can by the ring of itself ID is configured to the second ring ID, so that the network equipment carries out message transmissions in ring according to the second ring ID.First network equipment and each 3rd network equipment can carry out the calculating of the second ring ID simultaneously, and that is, step S207 and step S208 can be carried out simultaneously.

Further, first network equipment when calculating the second ring ID, detect by each second ring that can also just receive The MAC Address observing and predicting in literary composition removes, and calculates described second ring according to the remaining MAC Address receiving and the MAC Address of itself ID.MAC Address therein, after receiving each ring detecting message, can be stored by first network equipment, is calculating ring ID When, calculated according to all MAC Address of storage.So for first network equipment, that is, it is in the looped network of the first ring ID, It is in the looped network of the second ring ID, then first network equipment, when calculating the second ring ID, needs to get rid of to be not belonging to second again The MAC Address of the network equipment in the looped network of ring ID.Because first network equipment can receive the of other network equipments transmission Two rings detecting messages and Fourth Ring detecting message, and the second ring detecting message receives when generating the first ring ID, therefore the One network equipment can remove the MAC Address that each second ring receiving is detected in message, according to the MAC ground of remaining storage Location and the MAC Address of itself calculate the second ring ID.Similarly, each the 3rd network equipment will can also connect according to said method The first ring receiving is detected message and is removed with the MAC Address in each the second ring detecting message receiving, and is connect according to remaining The MAC Address receiving and the MAC Address of itself calculate described second ring ID.

The ring ID generation method that the present embodiment provides, in polycyclic ring network structure, if first network equipment has been connected to Ring ID is the looped network of the first ring ID, then when first network equipment be located at the first ring ID looped network in port outside, still have to Few one be in the port of connection status when, then when the second port that first network equipment is in not-connected status is changed into connecting During state, port outside the port in the looped network positioned at the first ring ID for the first network equipment sends and is based on mac frame the 3rd ring Detecting message, the 3rd ring detects the source MAC of message and target MAC (Media Access Control) address is the MAC Address of first network equipment, each Receive the 3rd network equipment transmission source MAC of the 3rd ring detecting message and target MAC (Media Access Control) address is own MAC address Message is detected so that each network equipment in network all knows the MAC Address of other network equipments in Fourth Ring, when first network sets After standby the 3rd ring receiving itself transmission detects message, or the 3rd network equipment receives the Fourth Ring detecting of itself transmission After message, all can perceive network cyclization, and the MAC Address according to all-network equipment in looped network calculates the second ring ID respectively, Achieve the automatically generating of looped network middle ring ID of multiring structure, improve the efficiency of ring ID configuration, be not likely to produce mistake simultaneously.

Further, in the embodiment depicted in figure 2, after step S206, that is, when receive that the 3rd ring detects message the After three network equipments send Fourth Ring detecting message, the 3rd network equipment can also start second timer.Second timer There is a Preset Time, after starting second timer, before the Preset Time time-out of second timer, this receives the 3rd ring 3rd network equipment of detecting message does not retransmit Fourth Ring detecting message.Namely when the 3rd network equipment sends one time the 4th After ring detecting message, do not retransmit detecting message in Fourth Ring within a period of time, even if the 3rd network equipment receives the again Three ring detecting messages or Fourth Ring detecting message, as long as second timer has not timed out, the 3rd network equipment does not retransmit the 4th yet Ring detects message.When the network equipment quantity that connects in a network is more, the 3rd network equipment in addition to the 3rd ring detects message, It is also possible to receive the Fourth Ring detecting message of other network equipments transmission.If the 3rd network equipment receives the 3rd ring detecting report After the Fourth Ring detecting message that literary composition and other network equipments send, all send Fourth Ring detecting message, the in network can be led to Fourth Ring detecting message amount is excessive, thus taking the excessive network bandwidth.Therefore, send Fourth Ring detecting in the 3rd network equipment After message, second timer being started, before second timer time-out, not sending Fourth Ring detecting message again, thus saving The about network bandwidth.

It should be noted that can not arrange long of the timing of second timer is it is impossible to make the network equipment receive When the 3rd ring sending to the network equipment newly connecting access network detects message, still can not send Fourth Ring detecting message.In addition, First network equipment is sending it is also possible to start second timer after the 3rd ring detects message, before second timer time-out not Retransmit source MAC and target MAC (Media Access Control) address is the Fourth Ring detecting message of own MAC address.

Further, in the embodiment depicted in figure 2, first network equipment specifically can be in the first end of first network equipment Mouthful and receive first ring detect message port outside, and outside second port be in connection status port send 3rd ring detecting message.First network equipment sends the 3rd ring and detects the trigger condition of message is first port and receiving first The port that first ring detects message has been connected to the looped network of the first ring ID, and first network equipment has other and is in and connects shape The port of state, then detects again and is in the second port of not-connected status and becomes connection status.Second port is the equal of The latter linked port of one network equipment.So that is, first network equipment detects after second port is changed into connection status, It is not to send the 3rd ring detecting message in the new second port connecting, but in the transmission of the port of connection before.Due to Each network equipment eventually forms the ring network structure of a closure, and after composition looped network, each network equipment can pass through looped network Loop configuration receive other network equipments transmission the 3rd ring detecting message or Fourth Ring detecting message, therefore, network sets During standby the 3rd ring detecting message in transmission, only need to be sent by the port of a connection, so can reduce in network Send the quantity of message.Similarly, the 3rd network equipment receiving the 3rd ring detecting message only can also receive the 3rd The port that ring detects message sends Fourth Ring detecting message.
