Specific embodiment

In term used in this application merely for the sake of the purpose for describing specific embodiment, and unrestricted the application.This Shen Please it is also intended to include most forms with " one kind ", " described " and " being somebody's turn to do " of the singulative used in claims, unless Context clearly shows that other implications.It is also understood that term "and/or" used herein refers to comprising one or more Associated any or all of project listed may be combined.

It will be appreciated that though various information, but this may be described using term first, second, third, etc. in the application A little information should not necessarily be limited by these terms.These terms are only used for being distinguished from each other open same type of information.For example, not departing from In the case of the application scope, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as One information.Depending on linguistic context, additionally, used word " if " can be construed to " and ... when ", or " when ... When ", or " in response to determining ".

A kind of message transmitting method is proposed in the embodiment of the present application, the method can apply to include at least two DR systems Network in, for each DR system, may each comprise at least two DR member devices.Additionally, during the network can also include Between forwarding unit, the intermediate forwarding devices are the network equipments being connected with DR member devices, and the intermediate forwarding devices can be by one The message that individual DR member devices send is transmitted to another DR member device, and the quantity of intermediate forwarding devices can be one or one More than individual.And, the intermediate forwarding devices can be the DR member devices of another DR system, it is also possible to not be setting for DR systems It is standby.

It is shown in Figure 1, the port 1 of the network equipment 1 and port 2, the port 3 of the network equipment 2 and port 4 can be bundled Together, so as to realize the port trunking of across a network equipment, therefore, the network equipment 1 and the network equipment 2 can set for DR member It is standby.Assuming that a network equipment X is connected (depending on not going out in Fig. 1) with the network equipment 1 and the network equipment 2 respectively, then network equipment X is Intermediate forwarding devices between the network equipment 1 and the network equipment 2, and, network equipment X is not the equipment of DR systems.Assuming that net Network equipment 3 and the network equipment 4 are connected (as shown in Figure 1) with the network equipment 1 and the network equipment 2 respectively, then the network equipment 3 and network Equipment 4 is the intermediate forwarding devices between the network equipment 1 and the network equipment 2, and, the network equipment 3 and the network equipment 4 are another The DR member devices of individual DR systems.

In one example, for DR member devices, a DR port set 1 can be included, and DR in DR port sets 1 into Member port includes port 1, port 2, port 3 and port 4.Likewise, being directed to intermediate forwarding devices, it is also possible to including DR port sets DR member ports in 1, and DR port sets 1 include port 5, port 6, port 7 and port 8.And, in two DR member devices Between also include IPL.

It is shown in Figure 2, it is the flow chart of the message transmitting method of proposition in the embodiment of the present application, the method can be applied Be may comprise steps of in DR member devices, and the method：

Step 201, receives the first message of other DR member devices transmission, and first message is other DR member devices When detecting the IPL between other DR member devices and this DR member devices and breaking down, set by other DR members with this What the intermediate forwarding devices of standby connection sent.

Step 202, judges whether first message carries the mark of this DR member devices.

If it is, step 203 is performed, if it is not, then abandoning first message.

Step 203, according to first message by the port of this DR member devices be placed in working condition (i.e. port be in UP shapes State) or it is placed in the state of being stopped (i.e. port is in DOWN states).

In one example, for " according to first message by the port of this DR member devices be placed in working condition or Be placed in the state of being stopped " process, can include：The preferential of other DR member devices is parsed from first message Level, and compare the priority of this DR member devices and the priority of other DR member devices；According to the comparative result of priority, The port of this DR member devices is placed in working condition or the state of being stopped is placed in.

For " according to the comparative result of priority, the port of this DR member devices being placed in working condition or is placed in and is stopped The process of only working condition ", if priority of the priority of this DR member devices higher than other DR member devices, by this DR The port of member device is placed in working condition；If the priority of this DR member devices is preferential less than other DR member devices Level, then be placed in the state of being stopped by the port of this DR member devices.Or, if the priority of this DR member devices is less than this its The priority of its DR member device, then be placed in working condition by the port of this DR member devices；If this DR member devices is preferential The port of this DR member devices is then placed in the state of being stopped by level higher than the priority of other DR member devices.

In one example, when detecting the IPL between this DR member devices and other DR member devices and breaking down, Then send the second message to the intermediate forwarding devices that are connected with this DR member devices, second message can carry other DR into Member's mark (such as MAC (Media Access Control, medium access control) address etc.) of equipment, this DR member devices it is excellent The contents such as first level, so that second message is sent to other DR member devices by the intermediate forwarding devices, and make other DR The port of other DR member devices is placed in working condition or is placed in the shape that is stopped by member device according to second message State.

Wherein, other DR member devices send the process of the first message, with the mistake that this DR member devices send the second message Journey is similar to, and in order to simplify description, in subsequent process, is said by taking the process that this DR member devices send the second message as an example It is bright, repeated no more for the process that other DR member devices send the first message.

In one example, can there is IPL between two DR member devices, the IPL is for transmission protocol message, with confidence Contents such as breath, list item information, and the IPL is to that should have IPL to identify, if DR member devices detect IPL ports DOWN (exception) or Person's communication abnormality, is considered as IPL and breaks down.Additionally, there is likely to be keep-alive (keepalive) between two DR member devices Link, if there is keep-alive link, each DR member device can be reported by the transmission keepalive of keep-alive isl cycle Text, if not receiving the keepalive messages of the DR member devices from opposite end within a specified time, it is believed that keep-alive link occurs Failure.

Based on this, when there is keep-alive link between this DR member devices and other DR member devices, then：As this DR members IPL between equipment and other DR member devices breaks down, and the guarantor between this DR member devices and other DR member devices When link living breaks down, just the second message is sent to the intermediate forwarding devices being connected with this DR member devices.Or, as this DR When IPL between member device and other DR member devices breaks down, no matter this DR member devices and other DR member devices Between keep-alive link whether break down, send the second message to the intermediate forwarding devices that are connected with this DR member devices.

In one example, for the mistake of " sending the second message to the intermediate forwarding devices being connected with this DR member devices " Journey, can include but is not limited to following manner：The first contingency table that inquiry is safeguarded in advance is identified by the corresponding IPL of the IPL, is obtained Mark, the DR port sets of corresponding other DR member devices are identified to the IPL；Wherein, first contingency table include IPL mark, Corresponding relation between mark, the DR port sets of other DR member devices.Further, generation includes other DR member devices Mark and this DR member devices priority the second message, and (i.e. the IPL identifies corresponding DR ends by the DR port sets Mouthful group) in DR member ports send second message to the intermediate forwarding devices being connected with this DR member devices.

In one example, for " by the DR member ports in the DR port sets to being connected with this DR member devices Intermediate forwarding devices send second message " process, can include but is not limited to：

If it is one that the IPL identifies corresponding DR port sets, can from all normal DR in the DR port sets into M DR member port is chosen in member port, and second report is sent to intermediate forwarding devices by the M DR member port chosen Text, the M is the positive integer more than or equal to 1.

If it is at least two that the IPL identifies corresponding DR port sets, can be chosen from least two DR port sets and referred to Determine DR port sets, and N number of DR member ports are chosen from all normal DR member ports in the specified DR port sets, and lead to Cross the N number of DR member ports chosen and send second message to intermediate forwarding devices, the N is the positive integer more than or equal to 1；Its In, the Selection Strategy of the specified DR port sets can include：Preferential DR member ports of choosing are normal DR port sets.

Wherein, above-mentioned second message is periodically to send, in order to reduce message quantity forwarded, if IPL mark correspondences DR port sets be one, then only by choose M DR member port transmission the second message, rather than from DR port sets All normal DR member ports send the second message, so as to reduce message quantity forwarded.If the IPL identifies corresponding DR ports Group is at least two, then the N number of DR member ports only by choosing send the second message, rather than from least two DR port sets All normal DR member ports send the second message, so as to reduce message quantity forwarded.

Wherein, for the process of " chosen from least two DR port sets and specify DR port sets ", it is assumed that DR port sets 1 are wrapped Including port A and port B, DR port set 2 includes port C and port D, if port A exceptions, port B, port C and port D are normal, Then the DR member ports of DR port sets 2 are normally, and DR port sets 1 have an abnormal, therefore choose DR port sets 2 as referring to Determine DR port sets.

In one example, the second message is sent to intermediate forwarding devices in M/N number of DR member ports by choosing When, in order to avoid the second message cannot be transferred to other DR member devices, can also be selected from remaining DR member ports are chosen K DR member port is taken, and the second message is sent to intermediate forwarding devices by the K DR member port chosen.Therefore, every In the individual transmission cycle, can be sent out to intermediate forwarding devices by the M/N number of DR member ports chosen and K DR member port Send the second message.

For the process of " K DR member port is chosen from remaining DR member ports are chosen ", can at random from selection K DR member port is chosen in remaining DR member ports, it is also possible to be ranked up to choosing remaining DR member ports, formed One transmit queue.The cycle is sent at first, first DR member port of transmit queue is chosen to k-th DR member end Mouthful, the cycle is sent at second, the K+1 DR member port to the 2K DR member port is chosen, by that analogy.Additionally, After choosing last DR member port of transmit queue, restart to choose from first DR member port of transmit queue.

For example, it is assumed that the M/N number of DR member ports chosen are port A, and remaining DR member ports are chosen for port B It is 1 with the value of port C, and K, then sends the cycle at first, the is sent to intermediate forwarding devices by port A and port B Two messages, the cycle is sent at second, and the second message is sent to intermediate forwarding devices by port A and port C, in the 3rd hair The cycle is sent, the second message is sent to intermediate forwarding devices by port A and port B, by that analogy.Certainly, said process is Several examples that the second message is sent to intermediate forwarding devices are given, in actual applications, other manner can also be used, It is without limitation as long as the second message can be sent into intermediate forwarding devices.

In one example, the second message except carry the mark of other DR member devices, this DR member devices it is preferential Outside level, one of herein below or any combination can also be carried：(this DR member devices set IPL marks with other DR members The IPL marks of the IPL between standby), the hop count that passes through of the mark (such as MAC Address) of this DR member devices, the second message (often passes through One equipment just adds 1, when hop count reaches predetermined threshold value, no longer transmits the second message), marker bit (represent the second message whether By the IPL between intermediate forwarding devices).And, the second message can include identification list, and above-mentioned other DR member devices Mark be located at identification list in.And, when the IPR between this DR member devices and at least two other DR member devices occurs During failure, then the mark of at least two other DR member devices is respectively positioned on identification list.

In one example, this DR member devices are after the first message for receiving the transmission of other DR member devices, if sheet The mark of DR member devices is carried in the identification list of the first message, then this can be deleted from the identification list of the first message The mark of DR member devices.If the identification list no longer mark including any DR member devices, this DR member devices no longer turn Send out the first message.If the identification list also mark including another DR member devices (such as or at least two DR member devices) Know, then this DR member devices can also be by the IPL between this DR member devices and another DR member devices, after modification The first message (deleting the first message of the mark of this DR member devices) be transmitted to another DR member devices.

It is shown in Figure 3, it is the flow chart of the message transmitting method of proposition in the embodiment of the present application, the method can be applied Be may comprise steps of in intermediate forwarding devices, and the method：

Step 301, the message that the DR member devices that reception is connected with this intermediate forwarding devices send；Wherein, the message is The DR member devices detect what is sent when itself and the IPL between other DR member devices break down, and the message is carried The mark of other DR member devices.

Step 302, other DR member devices are sent to by the message, so that other DR member devices are it is determined that the report When text carries the mark of other DR member devices, the port of other DR member devices is placed in by work shape according to the message State is placed in the state of being stopped.

In one example, the message can be the first message or the second message in above-described embodiment.

In one example, for the process of " message is sent into other DR member devices ", can include but not It is limited to following manner：Mode one, determination receive the DR port sets belonging to the DR member ports of the message, and by the DR ports The mark (mark is carried in the message) of group and other DR member devices, the second contingency table that inquiry is safeguarded in advance is obtained To corresponding DR member ports, and the message is sent to by other DR member devices by the DR member ports for obtaining.Mode 2nd, determine to receive the DR port sets belonging to the DR member ports of the message, and by the DR member end in the DR port sets Other DR member ports outside mouthful send the message, and the message is sent into other DR member devices.

Wherein, when intermediate forwarding devices safeguard have the second contingency table when, then intermediate forwarding devices employing mode one or side Formula two, other DR member devices are sent to by the message.It is when intermediate forwarding devices do not safeguard the second contingency table, then middle Forwarding unit employing mode two, other DR member devices are sent to by the message.

In one example, second contingency table can at least include DR port sets, the mark of DR member devices and DR Corresponding relation between member port.Based on this, intermediate forwarding devices are by the DR port sets and other DR member devices Mark inquire about after second contingency table, it is possible to obtain corresponding with the mark of the DR port sets and other DR member devices DR member ports.

In another example, if also there is IPL between intermediate forwarding devices and another intermediate forwarding devices, will report Text is sent to the process of other DR member devices, can also include following manner：The DR port sets are added in the message, And amended message is sent to by described another intermediate forwarding devices by the IPL；So that described another middle forwarding Equipment inquires about the second contingency table by the DR port sets and the mark of other DR member devices, obtains corresponding DR member Port, and message is sent to by other DR member devices by the DR member ports；Or, by the DR port sets Each DR member port sends message, and the message is sent into other DR member devices.

Below in conjunction with the application scenarios shown in Fig. 4, the above-mentioned technical proposal to the embodiment of the present application is illustrated.

As shown in figure 4, the network equipment 1 and the network equipment 2 are DR member devices, the network equipment 3 and the network equipment 4 are network Intermediate forwarding devices between equipment 1 and the network equipment 2, the network equipment 5 is the centre between the network equipment 1 and the network equipment 2 Forwarding unit.And, the network equipment 3 and the network equipment 4 are the DR member devices of another DR system, now, the He of the network equipment 1 The network equipment 2 is also the intermediate forwarding devices between the network equipment 3 and the network equipment 4.The network equipment 5 is not setting for DR systems It is standby.Describe for convenience, in subsequent process, with the network equipment 1 and the network equipment 2 for DR member devices, the network equipment 3, net Network equipment 4 and the network equipment 5 are to illustrate as a example by intermediate forwarding devices.

For DR member devices, including DR port sets 1 and DR port sets 2, the DR member ports in the DR port sets 1 include Port 1, port 2, port 3 and port 4, the DR member ports in the DR port sets 2 include port 9 and port 10.For network The intermediate forwarding devices of equipment 3 and the composition of the network equipment 4, including the DR member ports in DR port sets 1, and the DR port sets 1 Including port 5, port 6, port 7 and port 8.For this intermediate forwarding devices of the network equipment 5, including DR port sets 2, and should DR member ports in DR port sets 2 include port 11 and port 12.Under this application scene, it is assumed that the network equipment 1 and network set The corresponding IPL of IPL between standby 2 are designated IPL marks 1, additionally, the IPL between the network equipment 3 and the network equipment 4 is corresponding IPL is designated IPL marks 2.

In one example, the first contingency table that the network equipment 1 is safeguarded can be as shown in table 1, the network equipment 2 safeguard the One contingency table can be as shown in table 2, and the second contingency table of network equipment 3-dimensional shield can be as shown in table 3, what the network equipment 4 was safeguarded Second contingency table can be as shown in table 4, and the second contingency table that the network equipment 5 is safeguarded can be as shown in table 5.Certainly, it is above-mentioned to be The example of the first contingency table and the second contingency table, is not limited thereto in actual applications, and this first contingency table and second are closed The structure of connection table is repeated no more.

Under above-mentioned application scenarios, the message transmitting method that the embodiment of the present application is proposed may comprise steps of：

Step 1, when the IPL that the network equipment 1 detects this equipment and the network equipment 2 breaks down, to intermediate forwarding devices Message is sent, the message carries MAC Address, the priority of the network equipment 1 of the network equipment 2.

As shown in figure 4, due to there is keep-alive link between the network equipment 1 and the network equipment 2, therefore, when the network equipment 1 with IPL between the network equipment 2 breaks down, and keep-alive link between the network equipment 1 and the network equipment 2 is when breaking down, net Network equipment 1 can send message to intermediate forwarding devices.Or, when the IPL between the network equipment 1 and the network equipment 2 occurs event Barrier, but keep-alive link between the network equipment 1 and the network equipment 2, when not breaking down, the network equipment 1 can also be forwarded to centre Equipment sends message.

The network equipment 1 can obtain network by the first contingency table shown in the IPL 1 inquiry tables 1 of corresponding IPL marks The MAC Address of equipment 2, DR port sets 1 and DR port sets 2.Afterwards, the network equipment 1 can generate the MAC including the network equipment 2 The message of the priority of address and this equipment, and by the DR member ports in DR port sets 1 and/or DR port sets 2 to centre Forwarding unit sends the message.

In one example, for " network equipment 1 is by the DR member ports in DR port sets 1 and/or DR port sets 2 Send the message to intermediate forwarding devices " process, the network equipment 1 can be chosen from DR port sets 1 and DR port sets 2 specify DR port sets (such as DR port sets 1 and/or DR port sets 2, specific Selection Strategy repeat no more), and from specified DR port sets N number of DR member ports are chosen in DR member ports, and report is sent to intermediate forwarding devices by the N number of DR member ports chosen Text.

For example, the network equipment 1 is chosen specifies DR port sets for DR port sets 1, and from the DR member ports of DR port sets 1 Port 1 is chosen, and message is sent to the network equipment 3 by port 1.Or, it is DR ends that the network equipment 1 is chosen and specifies DR port sets Mouth group 2, and port 9 is chosen from the DR member ports of DR port sets 2, and message is sent to the network equipment 5 by port 9.Or Can be defined as DR port sets 1 and DR port sets 2 specifying DR port sets by person, the network equipment 1, from the DR of DR port sets 1 into Member chooses port 1 and port 2 in port, and port 9 is chosen from the DR member ports of DR port sets 2, and so, the network equipment 1 leads to Cross port 1 and send message to the network equipment 3, message is sent to the network equipment 4 by port 2, by port 9 to the network equipment 5 Message is sent, so as to improve reliability of the message transmissions to the network equipment 2.Describe for convenience, subsequently as a example by choosing port 1 Illustrate.

In one example, the message except carry the network equipment 2 MAC Address, the priority of the network equipment 1 in addition to, One of herein below or any combination can also be carried：The jump that the IPL marks 1, MAC Address of the network equipment 1, message pass through Number, marker bit etc..And, the message can also include an identification list, and the MAC Address of the above-mentioned network equipment 2 can be with It is carried in the identification list.

Step 2, intermediate forwarding devices (such as network equipment 3) receive the message that the network equipment 1 sends.

The message is sent to the network equipment 2 by step 3, intermediate forwarding devices (such as network equipment 3).

The network equipment 3 checks whether the hop count that message passes through reaches predetermined threshold value after the message is received, first, if reached To predetermined threshold value, then the message is abandoned, no longer transmit the message, so as to avoid loop problem.If not up to predetermined threshold value, Whether the identification list for checking the message is empty.If sky, then the message is abandoned, no longer transmit the message.If not being sky, Then check and locally whether there is corresponding second contingency table of the message, if it is present the employing mode one of the network equipment 3, by this Message is sent to the network equipment 2.If it does not exist, then the employing mode two of the network equipment 3, the network equipment 2 is sent to by the message.

Mode one, the network equipment 3 determine to receive the DR port sets belonging to the DR member ports (i.e. port 5) of the message, The DR port sets are DR port sets 1.The network equipment 3 (is carried in the message by the MAC Address of DR port sets 1 and the network equipment 2 In), the second contingency table shown in inquiry table 3 obtains corresponding DR member ports for port 6, and is sent out the message by port 6 Give the network equipment 2.

In one example, the network equipment 3 can also be by the IPL between the network equipment 3 and the network equipment 4, by message It is sent to the network equipment 4.Before the message is sent, the marker bit of the message can be set to IPL correspondences by the network equipment 3 IPL marks 2, and add transparent transmission information in the message, the transparent transmission information can include that IPL identifies 2 and DR port sets 1 (i.e. Receive the DR port sets belonging to the port 5 of the message).

The network equipment 4 finds that marker bit is IPL marks 2 after the message is received, and represents that the message comes from IPL marks Know 2 corresponding IPL, therefore, the network equipment 4 no longer sends the message by the IPL to the network equipment 3.And, the network equipment 4 Can by the MAC Address (carrying is in the message) of transparent transmission information (i.e. IPL identify 2 and DR port sets 1) and the network equipment 2, The second contingency table shown in inquiry table 4, obtains corresponding DR member ports for port 8, and be sent to the message by port 8 The network equipment 2.

Mode two, the network equipment 3 determine to receive the DR port sets belonging to the DR member ports (i.e. port 5) of the message, The DR port sets are DR port sets 1, and are sent out by other the DR member ports (i.e. port 6) outside the port 5 in DR port sets 1 The message is given, message is sent to the network equipment 2.
