Embodiment
See also Fig. 1, it is a kind of network topology structure scene schematic diagram, wherein, S1, S2, S3, S4 and S5 are respectively the edge device in the switching network, with STP (Spanning Tree Protocol, Spanning-Tree Protocol) is example, S1, the switching network operation STP at S2 and S3 place, the network at S4 and S5 place does not move STP, can transparent transmission protocol massages each other in order to make between S1 and the S2, promptly require S1, the STP protocol massages of the network at S2 and S3 place can pass the network at S4 and S5 place, because the STP protocol massages is a kind of BPDU protocol massages, therefore, need be between S4 and S5 configuration bpdu Tunnel to realize the transparent transmission function, like this, after S4 received the STP protocol massages that S1 sends, the target MAC (Media Access Control) address of conversion STP protocol massages made form the forwarded S4 and S5 between of former STP protocol massages with data message, restore back the target MAC (Media Access Control) address of STP protocol massages behind the arrival S5, be forwarded to S2 at last.After the network topology structure among Fig. 1 is stable, if connecting the interface of S5, S2 is blocked, the interface that S3 connects S2 is blocked, then terminal 1 is specially to the data message flow of terminal 2: terminal 1-〉S4-〉S1-〉S2-〉terminal 2.
But, if the network topology at S1, S2 and S3 place changes, and after STP consults again, S2 is connected the interface blocking-up of S1, and the interface of S2 connection S5 returns to normal condition, as shown in Figure 2, at this moment, because the network at S4 and S5 place does not move STP, change in topology that can't sensing network, terminal 1 to the routing direction of data message on S4 of terminal 2 still for S4 mails to S1, and since S2 connect the interface of S1 and be blocked, above-mentioned data message flow is obstructed, finally can cause losing of data message.At above-mentioned scene, change the problem of the obliterated data message brought for fear of topology of networks, below in conjunction with drawings and Examples, the embodiment of the present application is described in detail.Should be appreciated that specific embodiment described herein only in order to explanation the application, and be not used in qualification the application.
Embodiment one
See also Fig. 3, it is the flow chart of an embodiment of the sending method of a kind of data message of the present invention, and this method may further comprise the steps:
Step 301: when receiving the BPDU protocol massages, judge whether the described BPDU protocol massages that receives is to change relevant message with topology of networks.
Wherein, whether the described BPDU protocol massages that receives of described judgement is to change relevant message with topology of networks to comprise: judge that whether each BPDU protocol massages of receiving is and topology of networks changes the message of being correlated with; Perhaps, judge whether receive the BPDU protocol massages in the special time is to change relevant message with topology of networks.
For example, with the topological structure shown in Fig. 1 is example, after the edge device S4 at BPDU Tunnel two ends or S5 receive a BPDU protocol massages, just judge whether this BPDU protocol massages is to change relevant message with S1, S2 with S3 place topology of networks.Perhaps, in order to save consumption, also can judge that whether the BPDU protocol massages that receives in the special time is and S1 by network equipment S4 or S5, S2 changes relevant message with S3 place topology of networks, for example can set a timer, judge that whether the BPDU protocol massages that receives in the timer timing is and S1, S2 changes relevant message with S3 place topology of networks, also the BPDU protocol massages that is received in the timer timing can be carried out buffer memory, and when timer expiry, the BPDU protocol massages that is received in the timer timing to buffer memory by edge device S4 or S5 judges, judge whether into S1, S2 changes relevant message with S3 place topology of networks.
When S4 or S5 judge whether when changing relevant message with S1, S2 with S3 place topology of networks the BPDU protocol massages that receives, comprise: when the BPDU protocol massages is parsing Spanning-Tree Protocol (Spanning Tree Protocol, STP) during message, resolve this STP BPDUs, obtain the heading of described STP BPDUs; According to TC flag bit that from the heading of described STP BPDUs, reads or type of message sign, judge whether the BPDU protocol massages is to change relevant message with S1, S2 and S3 place topology of networks; Perhaps resolve described BPDU protocol massages, obtain the heading of described BPDU protocol massages; Judge according to the flush territory of from the heading of described BPDU protocol massages, reading whether described BPDU protocol massages is to change relevant message with S1, S2 and S3 place topology of networks.
For example, in case variation has taken place in the network configuration of topological network, be blocked as the interface as S2 connection S5 among Fig. 1, when the interface of S3 connection S2 is blocked, the TC message will be transmitted in system in topological network, variation has taken place to show topology of networks in TCN message or flush message, wherein, in the heading of STP BPDUs, be provided with the TC flag bit, if the TC flag bit is set to 1, represent that promptly STP BPDUs is the TC message, be that the BPDU protocol massages is and S1, S2 changes relevant TC message with S3 place topology of networks, if the TC flag bit is set to 0, represent that promptly STP BPDUs is not the TC message, promptly the BPDU protocol massages is not and S1, S2 changes relevant message with S3 place topology of networks.
Equally, be provided with the type of message sign in the heading of STP BPDUs, if the type of message sign is put 1, represent that promptly STP BPDUs is the TCN message, be that the BPDU protocol massages is to change relevant TCN message with S1, S2 and S3 place topology of networks, otherwise the expression STP BPDUs is not the TCN message, and promptly the BPDU protocol massages is not to change relevant message with S1, S2 and S3 place topology of networks.
Equally, expansion has the flush territory in the heading of BPDU protocol massages, if the flush territory is set to 1, represents that promptly the BPDU protocol massages is the flush message, if the flush territory is set to 0, represents that promptly the BPDU protocol massages is not the flush message.
Step 302: if the described BPDU protocol massages that receives is for changing relevant message with topology of networks, the data message that receives being sent to the edge device of opposite end in the mode of broadcasting.
Wherein, described the data message that receives is comprised with the edge device that the mode of broadcasting sends to the opposite end: according to the interface that receives the described message relevant with the variation of edge device place topology of networks, deletion and described interface related MAC Address list item are so that the edge device at described BPDU Tunnel two ends sends to described data message the edge device of opposite end in the mode of broadcasting.
Usually, in two layer-switching technologies, edge device belongs to data link layer device, edge device is set up corresponding relation with MAC Address and the interface corresponding with this MAC Address, be recorded in this corresponding relation in the address table of self inside as a list item, the destination-mac address information of edge device in can the recognition data message is transmitted data message according to target MAC (Media Access Control) address inquire address table.In the present embodiment, with the BPDU protocol massages is that STP BPDUs is an example, when edge device S4 judges the protocol massages that receives from S1 and S5 and is TC message or TCN message, can from the address table of self maintained, delete interface that is connected with S1 and the interface related MAC Address list item that is connected with S5, also can delete the whole address table of S4 self, at this moment, the interface that is connected with S1 is also just correspondingly deleted with the interface related MAC Address list item that is connected with S5.
Usually, in three layer-switching technologies, so-called " address resolution " is exactly the process that purpose IP address transition is become target MAC (Media Access Control) address before sending message.The basic function of ARP is exactly that IP address, MAC Address and corresponding outgoing interface are set up corresponding relation, this corresponding relation is recorded in the arp cache table as a list item, and by the purpose IP address in the data message, inquiry corresponding target MAC Address and corresponding interface.When edge device S4 judges the protocol massages that receives from S1 and S5 and is the flush message, can from the arp cache table of self maintained, delete interface that is connected with S1 and the interface related ARP list item that is connected with S5, also can delete whole arp cache table, at this moment, the interface that is connected with S1 is also just correspondingly deleted with the interface related ARP list item that is connected with S5.
Send datagram to edge device B (192.168.1.1) with edge device A (192.168.1.5) and to be example.When sending datagram, edge device A can seek the purpose IP address whether edge device B is arranged in the arp cache table of oneself.If have, also just known the target MAC (Media Access Control) address of edge device B, directly this target MAC (Media Access Control) address is write message the inside and transmission; If do not find corresponding purpose IP address in the arp cache table, edge device A will send a broadcasting on network, and target MAC (Media Access Control) address is " FF.FF.FF.FF.FF.FF ", and this expression all edge devices in the same network segment send data message.
Need to prove, above-mentioned " edge device of opposite end " is meant all edge devices that have annexation with some edge devices, for example, with the edge device S4 among Fig. 1 is example, the edge device that has annexation with edge device S4 is S1 and S5, then the edge device of the opposite end of edge device S4 is S1 and S5, and S4 sends to S1 and S5 with the data message that receives in the mode of broadcasting.
Need to prove that also edge device can comprise switch, router, multi-layer switches, IAD, MAN or the WAN device that is installed on the edge network, the packet of being responsible for access device and core/backbone network equipment room transmits.Edge device is a kind of physical equipment of application data link layer (second layer) and network layer (the 3rd layer) technology.
When the described BPDU protocol massages that receives is not when changing relevant message with topology of networks, the data message that receives to be sent to the indicated edge device of destination address.
For example, it still is example with Fig. 1, when edge device S4 judges the BPDU protocol massages that receives is not when changing relevant message with S1, S2 and S3 place topology of networks, promptly, edge device S4 does not receive with S1, S2 and S3 place topology of networks and changes relevant message, the network configuration that shows topological network does not change, and at this moment, still data message is sent to the indicated edge device of destination address.
One of ordinary skill in the art will appreciate that, after above-mentioned steps 302, can also comprise that common MAC address learning or ARP resolve, after MAC address learning or ARP parsing, set up new data message forwarding path, the data message that receives is sent to the indicated edge device of destination address, no longer send to the edge device of opposite end in the mode of broadcasting.
As can be seen from the above-described embodiment, edge device by BPDU Tunnel two ends, tunnel, bridge protocol data unit is analyzed the BPDU protocol massages that receives, when judging that the BPDU protocol massages is not when changing relevant message with topology of networks, data message to be sent to the indicated edge device of MAC Address; When judging that the BPDU protocol massages is change in topology TC message or refreshes the flush message, illustrate that variation has taken place topology network architecture, at this moment, the data message that receives is sent to the edge device of opposite end in the mode of broadcasting, be equivalent to enlarge the transmit path of data message, when network topology changes, can avoid the problem of the obliterated data message that the change in topology of network brings.
Embodiment two
Please in conjunction with topological network line structure figure shown in Figure 1, consult Fig. 4, it is the flow chart of another embodiment of the sending method of a kind of data message of the present invention, may further comprise the steps:
Step 401: the edge device S4 at BPDU Tunnel two ends, tunnel, bridge protocol data unit receives the BPDU protocol massages;
Step 402: edge device S4 judges whether the BPDU protocol massages that receives is TC message, TCN message or flush message, if, enter step 403, if not, enter step 405;
Wherein, edge device S4 can just judge once whether this BPDU protocol massages is TC message, TCN message or flush message whenever receiving a BPDU protocol massages, also can start a timer, judge whether the BPDU protocol massages that receives in the timing of timer is TC message, TCN message or flush message.
For the judgement of TC message, specifically can be, resolve STP BPDUs, obtain the heading of STP BPDUs, from the heading of STP BPDUs, read the TC flag bit, judge whether the TC flag bit is put 1, if described STP BPDUs is the TC message.
For the judgement of TCN message, specifically can be, resolve STP BPDUs, obtain the heading of described STP BPDUs; Read the type of message sign from the heading of described STP BPDUs, judge whether described type of message sign is put 1, if described STP BPDUs is the TCN message.
For the judgement of flush message, specifically can be to resolve the BPDU protocol massages, obtain the heading of BPDU protocol massages, from the heading of BPDU protocol massages, read the flush territory, judge whether the flush territory is put 1, if described BPDU protocol massages is the flush message.
Step 403: according to the interface that receives TC message, TCN message or flush message, edge device S4 deletion and interface related MAC Address list item;
In two layers of switching network, if the BPDU protocol massages that edge device S4 receives from S1 is the TC message, then will and S4 and S1 between interface related MAC Address list item from address table, delete.
Step 404: when edge device S4 receives data message, data message is sent to the edge device of opposite end in the mode of broadcasting;
For example, when edge device S4 judges that the BPDU protocol massages that self receives is the TC message, the data message that receives is sent to the edge device S1 and the S5 of opposite end in the mode of broadcasting.
Be blocked if S2 connects the interface of S5, the interface that S3 connects S2 is blocked, and as shown in Figure 2, then terminal 1 is specially to the data message flow of terminal 2: terminal 1-〉S4-〉S1-〉S2-〉terminal 2.If S1, S2 and S3 network topology change, and after STP consults again, S2 is connected the interface blocking-up of S1, and the interface of S2 connection S5 returns to normal condition, as shown in Figure 3, because S4 can receive the TC message of STP when consulting again, TCN message or flush message, therefore the mode with broadcasting sends to S1 and S5 simultaneously with data message, because S2 connects the interface blocking-up of S1, data message on this path can be lost, the terminal of flowing through 1-〉S4-〉S5-〉S2-〉data message of terminal 2 then normally sent, and guaranteed that after topological network changes data message can not lost.
Step 405: when edge device S4 did not receive TC message, TCN message or flush message, edge device S4 sent to the indicated edge device of destination address with data message.
In addition, when edge device S4 deleted and S 1 between interface related MAC Address list item after, if receive for example data message of terminal 2 transmissions of a data message from S5 again, then can be according to the source MAC of this data message for example MAC Address of terminal 2 and the incoming interface of this data message, based on MAC address learning mechanism, in address table, set up a new MAC Address list item.After MAC address learning, when receiving the data message that mails to terminal 2 once more, edge device S4 searches address table, finds the MAC Address list item of terminal 2 correspondences, according to the interface in this MAC Address list item this data message is sent to terminal 2.
As can be seen from the above-described embodiment, edge device by BPDU Tunnel two ends, tunnel, bridge protocol data unit is analyzed the BPDU protocol massages that receives, when judging that the BPDU protocol massages is not when changing relevant message with topology of networks, data message to be sent to the indicated edge device of MAC Address; When judging that the BPDU protocol massages is the message relevant with the topology of networks variation, illustrate that variation has taken place topology network architecture, at this moment, each data message that receives is sent to the edge device of opposite end in the mode of broadcasting, be equivalent to enlarge the transmit path of data message, when network topology changes, can avoid the problem of the obliterated data message that the change in topology of network brings.
