Specific embodiment

Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall in the protection scope of this application.

Inventor has found when studying the prior art: the prior art when be caused in stack equipment due to link failure respectively at The a large amount of message of transparent transmission is needed between member's equipment, and the first member device in stack equipment receives multiple pileup device external hair The message that send and after handling message, the second member device for receiving the message of the first member device forwarding needs again Downlink Switch can be just transmitted to by being handled, and it is lower to will lead to message transmissions efficiency.

To improve message transmissions efficiency, each member device in the embodiment of the present application in stack equipment is each of itself Interface is configured with the VLAN value for identifying interface, and multiple interfaces can be divided to the same business in the prior art VLAN (i.e. multiple interface VLAN values having the same) is different, this application involves VLAN value be for distinguishing interface, it is different Interface have different VLAN values.When each member device enables stacking opening, each member device can incite somebody to action the embodiment of the present application Itself stacking opening is bound with the VLAN value for identifying local each interface, such as: the first member device and the second member device it Between stacking opening it is enabled when, the first member device can be by the VLAN value of stacking opening and each interface for being used to identify the first member device Binding, the second member device can bind stacking opening and the VLAN value for each interface for being used to identify the second member device.

Forwarding principle based on exchange chip can be to the VLAN value with the interface after by certain interface to message Other identical interfaces forward the message, and the application may be implemented to connect when a member device by stacking opening through the above configuration When receiving the message for carrying VLAN value, the VLAN value is inevitable to bind with stacking opening, so the message can be forwarded to by exchange chip The corresponding outgoing interface of VLAN value, and then E-Packeted by the outgoing interface.

Based on above-mentioned configuration, the embodiment of the present application is somebody's turn to do after the first member device receives the first message when determining to send When the outgoing interface of message is located at the second member device, it can obtain with the first VLAN value of outgoing interface binding and be bound with stacking opening The 2nd VLAN value, and the first VLAN value and the 2nd VLAN value are encapsulated to the heading of the first message, obtain the first encapsulation report First encapsulated message is transmitted to stacking opening then according to the 2nd VLAN value by text, then deletes include in the first encapsulated message the Two VLAN values, obtain the second encapsulated message, the second encapsulated message are sent second to member device by stacking opening, and then second The first VLAN value that member device can include by the second encapsulated message determines outgoing interface, can delete the first VLAN value, pass through Outgoing interface forwards the first message, and the second encapsulated message received due to the second member device includes the first VLAN value, and the second one-tenth Member's equipment can directly be E-Packeted by the corresponding outgoing interface of the first VLAN value of exchange chip, since exchange chip is that hardware turns Hair, will not be by the CPU of the message up sending to equipment, so the second member device is just not necessarily to handle the message, but directly It connects and is forwarded, the efficiency of transmission of message can be improved.

The method forwarded below by way of specific embodiment to message provided by the embodiments of the present application is illustrated.

The embodiment of the present application can be applied to the network environment with stack equipment, between each member device of stack equipment Stacking opening transparent transmission message can be passed through.

Wherein, each member device in stack equipment is the equipment with message transmission function, such as can be fire prevention The equipment such as wall, switch or router.

By taking application scenarios shown in FIG. 1 as an example, when link breaks down in stack equipment, the transmission situation of message is at least Including following two situation:

Situation one: perhaps 3 failure of link or the equal failure of link 2 and link 3, upstream switch pass through 2 failure of link After message is sent to member device 1 by link 1, message transmission to member device 2, member device 2 are passed through link by member device 1 Message is sent to Downlink Switch by 4.

Situation two: perhaps 4 failure of link or the equal failure of link 1 and link 4, upstream switch pass through 1 failure of link After message is sent to member device 2 by link 2, message transmission to member device 1, member device 1 are passed through link by member device 2 Message is sent to Downlink Switch by 3.

In conjunction with Fig. 1, the embodiment of the present application provides a kind of method of message forwarding, and this method is applied to the in stack equipment One member device, stack equipment further include the second member device being connect with the first member device by stacking opening, the first member Equipment can be member device 1 or member device 2 in Fig. 1, correspondingly, the second member device is then the member device 2 in Fig. 1 Or member device 1.It is said so that member device 1 is the first member device, member device 2 is the second member device as an example below It is bright.As shown in Fig. 2, shown in this method is specific as follows.

S201, the first member device receive the first message, when the outgoing interface for determining stack equipment the first message of transmission is located at When the second member device, the 2nd VLAN value with the first VLAN value of outgoing interface binding and with stacking opening binding is obtained, and will First VLAN value and the 2nd VLAN value are encapsulated to the heading of the first message, obtain the first encapsulated message.

In system initialization process, the first member device be respectively itself each interface be configured with one for identify connect The VLAN value of mouth, similarly, the second member device are also respectively that itself each interface is configured with one for identifying interface VLAN value.

Illustratively, if there is 8 interfaces on the exchange chip of the first member device, it can configure the VLAN of this 8 interfaces Value is respectively 1 to 8.Equally, if there is 8 interfaces on the exchange chip of the second member device, it can also be configured the VLAN of this 8 interfaces Value is respectively 1 to 8.Above-mentioned configuration is merely illustrative, and in actual implementation, the configuration of the VLAN value of each interface is without being limited thereto, configuration Principle is that each member device is that itself each interface configures different VLAN values.It, can be in addition, in system initialization Logic index value is configured for the interface of each member device, to pass through the logic index value corresponding interface easy to find.

First member device includes that hardware layer, driving layer and podium level, hardware layer are the exchange core of the first member device Piece, after exchange chip receives the first message, can by the first message up sending to driving layer, driving layer again by the first message up sending extremely Podium level, the business module in podium level can be identified and be handled to the first message, when business module determines the first message When outgoing interface is located at the second member device, the first member device can obtain with outgoing interface binding the first VLAN value and with stacking 2nd VLAN value of mouth binding.

Wherein, due to the Interface status of member device each in stack equipment, interface identifier (such as the interface logic index Value), the information such as forwarding table and routing table be mutually synchronized, therefore may be implemented can be according to storage in the first member device Above- mentioned information determine the outgoing interface of the first message on which platform member device.Optionally, business module can be true according to forwarding-table item It is fixed to determine for sending the interface number of the outgoing interface of the first message, or according to load balancing for sending the first message The interface number of outgoing interface, the mode of the outgoing interface for determining the first message, the application is with no restriction.

Specifically, when the stacking opening between the first member device and the second member device is enabled, the first member device and The interface message of each interface of itself can be mutually synchronized between second member device, interface message includes Interface status, interface number And the corresponding logic index value of interface number.

First member device can calculate the VLAN of each interface of the second member device according to the interface number of the second member device Value, the method that the first member device calculates the VLAN value of each interface of the second member device, configures itself with the second member device Each interface VLAN value method it is identical.

As an example, interface number can be by slot (slot number), subslot (sub- slot number), port (interface serial number) Three parts composition, the corresponding VLAN value of interface number can be with are as follows:

VLAN=slot*2⁸+subslot*2⁴+port+stratIndex

Wherein, StartIndex is preset starting index value.

The calculation of VLAN value in certain the embodiment of the present application is without being limited thereto, and it is raw that other can be implemented as distinct interface It also can be applied in the present embodiment at the method for different VLAN values.

By above-mentioned calculating, the first member device can determine that the interface number-VLAN value of the second member device or interface number-are patrolled Collect the corresponding relationship between index value-VLAN value.

So the first member device can be according to the corresponding with logic index value of each interface number of the second member device Relationship obtains the corresponding target logic index value of interface number of outgoing interface, and it is corresponding for identifying to search target logic index value First VLAN value of outgoing interface.

It, can be according to interface number and logic after the business module of the podium level of first member device determines the interface number of outgoing interface The corresponding relationship of index value determines the corresponding target logic index value of the interface number of outgoing interface, then by target logic index value It is handed down to driving layer, driving layer it is corresponding can to search target logic index value according to the corresponding relationship of logic index value and VLAN value For identifying the first VLAN value of outgoing interface.

In addition, driving layer may further determine that the target interface on the first member device as stacking opening, obtain for identifying mesh 2nd VLAN value of tag splice mouth.

For example, if outgoing interface is the interface 1 of the second member device, it may be determined that the first VLAN value is 1, if the first member device On as stacking opening target interface be interface 3, then can determine the 2nd VLAN value be 3.

First VLAN value and the 2nd VLAN value can be encapsulated in two layers of report of the first message by the driving layer of the first member device In literary head, the format of the first encapsulated message obtained after encapsulation can be " [target MAC (Media Access Control) address] [source MAC] [second VLAN value] [the first VLAN value] [protocol type] [data portion] ".

Optionally, if the first member device determines that the first message need to be transmitted via local device, the first message is forwarded extremely Downlink Switch.

S202, the first member device determine the stacking opening for being used for transmission the first encapsulated message according to the 2nd VLAN value.

After the driving layer of the first member device obtains the first encapsulated message, the first encapsulated message can be transmitted to exchange core Piece, exchange chip can recognize outermost VLAN value in the first encapsulated message, i.e. the 2nd VLAN value, exchange chip can determine second VLAN value is the VLAN value of the stacking opening of itself, and then determination can pass through first encapsulated message of stacking port transmission.

S203, the first member device delete the 2nd VLAN value that the first encapsulated message includes, and obtain the second encapsulated message, will Second encapsulated message is sent to the second member device by stacking opening, so that the second member device is determined by the first VLAN value Interface deletes the first VLAN value that the second encapsulated message includes, obtains the first message, forwards the first message.

It specifically, can after the exchange chip of the first member device determines and stacking the first encapsulated message of port transmission can be used The 2nd VLAN value in first encapsulated message is deleted, the format of the second encapsulated message obtained at this time can be " [purpose MAC Address] [source MAC] [the first VLAN value] [protocol type] [data portion] ".

Then the second encapsulated message can be sent to the second member by stacking opening and set by the exchange chip of the first member device It is standby, after the exchange chip of the second member device receives the second encapsulated message by stacking opening, it can recognize to the second encapsulated message In include the first VLAN value, due to stacking opening and each interface for identifying the second member device of the second member device The binding of VLAN value, so the exchange chip of the second member device can determine that the first VLAN value is the VLAN value of stacking opening binding, into And the exchange chip of the second member device can determine that the outgoing interface of second encapsulated message is the corresponding outgoing interface of the first VLAN value, Then the exchange chip of the second member device can delete the first VLAN value that the second encapsulated message includes, and obtain the first message, pass through Outgoing interface forwards the first message.

It should be noted that since the exchange chip of the second member device determines carry in the second encapsulated message first VLAN value and stacking opening are bound, so exchange chip can forward the first message by the corresponding outgoing interface of the first VLAN value, are not necessarily to It will send on second encapsulated message to the driving layer and podium level of the second member device, need to only be carried out in exchange chip hardware view Forwarding.

It, can be by stacking opening and each interface for being used to identify the first member device when the first member device enables stacking opening The binding of VLAN value.If the first member device in this way receives the message for carrying VLAN value by stacking opening, if the first member sets Standby exchange chip determines that the VLAN value and stacking opening are bound, and can be E-Packeted by the corresponding interface of VLAN value.

Correspondingly, the first member device can release stacking opening and the second member when the first member device deletes stacking opening Binding relationship between the VLAN value of each interface of equipment.

Similarly, when the second member device enable stacking opening when, can by stacking opening be used to identify each of the second member device The VLAN value of interface is bound.When the second member device deletes stacking opening, stacking opening can be released and set with for identifying the first member Binding relationship between the VLAN value of standby each interface.

It is understood that determining that stack equipment sends the second report if above-mentioned second member device receives the second message When the outgoing interface of text is located at the first member device, it can also obtain with the 3rd VLAN value of outgoing interface binding and be bound with stacking opening The 4th VLAN value, and the 3rd VLAN value and the 4th VLAN value are encapsulated to the heading of the second message, obtain third encapsulation report Text.

For example, the format of third encapsulated message can be " [target MAC (Media Access Control) address] [source MAC] [the 4th VLAN value] [the Three VLAN values] [protocol type] [data portion] "

Then the second member device can determine the stacking opening for being used for transmission third encapsulated message according to the 4th VLAN value.

Then the 4th VLAN value that third encapsulated message includes is deleted, the 4th encapsulated message is obtained.

For example, the format of the 4th encapsulated message can be " [target MAC (Media Access Control) address] [source MAC] [the 3rd VLAN value] [association Discuss type] [data portion] "

4th encapsulated message can be sent to the first member device, and then the first member by stacking opening by the second member device Equipment determines outgoing interface by the 3rd VLAN value, deletes the 3rd VLAN value that the 4th encapsulated message includes, obtains the second message, turns Send out the second message.

Corresponding to embodiment shown in Fig. 2, the embodiment of the present application also provides a kind of message forwarding method, and this method is applied to The second member device in stack equipment, stack equipment further include the first member being connect with the second stack equipment by stacking opening Equipment, the first member device can be member device 1 or member device 2 in Fig. 1, correspondingly, the second member device is then Fig. 1 In member device 2 or member device 1.Hereinafter be the first member device with member device 1, member device 2 is that the second member sets It is illustrated for standby.As shown in figure 3, shown in this method is specific as follows.

S301, the second member device receive the second encapsulated message that the first member device is sent, the second envelope by stacking opening Filling message includes the first VLAN value.

Optionally, each interface that the second member device may respectively be itself configures one for identifying the VLAN of interface Value.The first VLAN value for including in the second encapsulated message that second member device receives is for identifying the second member device The VLAN value of one of interface.

It whether include the first VLAN value in S302, the judgement of the second member device and the VLAN value of stacking opening binding.

When enabled stacking opening, the second member device can be by stacking opening and each interface for being used to identify the second member device The binding of VLAN value.Correspondingly, the second member device can release stacking opening and set with for identifying the second member when deleting stacking opening Binding relationship between the VLAN value of standby each interface.

So the second member device can if the first VLAN value is the VLAN value for identifying the interface of the second member device It include the first VLAN value in the determining VLAN value with stacking opening binding.

If including the first VLAN value in S303, the VLAN value bound with stacking opening, determine to connect by the first VLAN value Mouthful, and the first VLAN value that the second encapsulated message includes is deleted, obtain the first message.

Wherein, the second member device can determine that the first VLAN value is corresponding according to the corresponding relationship of interface number and VLAN value Outgoing interface, the second member device determines the outgoing interface of message is used for transmission on the exchange chip of itself after, can by second encapsulation The first VLAN value in message is deleted.

S304, the second member device forward the first message by outgoing interface.

It should be understood that the exchange chip of the second member device can forward the first message by the outgoing interface of itself.

Using message forwarding method provided by the embodiments of the present application, the second member device is the first one-tenth received by stacking opening After the second encapsulated message that member's equipment is sent, however, it is determined that there are the first VLAN values in the VLAN value bound with stacking opening, then can be true The fixed corresponding outgoing interface of first VLAN value, and the first VLAN value that the second encapsulated message includes is deleted, the first message is obtained, is passed through Outgoing interface forwards the first message, it is seen that since the second member device is carried by stacking opening received second encapsulated message center 2nd VLAN value, so the second member device is just not necessarily to carry out operational processing to the second encapsulated message, it only need to be via exchange The outgoing interface of chip is forwarded message, and the efficiency of transmission of message can be improved.

Optionally, the embodiment of the present application can also be applied to the scene that stack equipment includes two or more member device, heap It may include the first member device and at least one second member device in stacking device, wherein the first member device is outer for receiving The equipment for the message that portion's equipment is sent, the second member device are to set to the equipment of external equipment transmission message or the second member The standby member device in addition to the first member device is with the equipment to external equipment transmission message.Wherein, outside here is set The standby equipment referred in addition to the member device for constituting stack equipment.By taking Fig. 4 as an example, it is assumed that member device 1 is external equipment hair The equipment of the message sent, member device 3 are the equipment for sending message to external equipment, then member device 1 is the first member device, Member device 2 and 3 is the second member device.

Based on above-mentioned scene, the embodiment of the present application also provides a kind of message forwarding method, applied in stack equipment One member device, this method specifically includes the following steps:

Step 1: receive the first message, when determine stack equipment send first message outgoing interface be not located at When member's equipment, the transmission path that the first message is sent to outgoing interface is determined, transmission path includes the second member successively passed through Equipment.

After first member device receives the first message, however, it is determined that itself is used for the chain to external the first message of device forwards Road failure then can determine the state of outgoing interface of other member devices for connecting external equipment in stack equipment.Due to using After Stack Technology, each member device in stack equipment will be used as an equipment, and the first member device can obtain stacking The interface message and Interface status of each member device of other in equipment.

If the first member device determines that the outgoing interface of the second member device connected by the stacking opening of itself is available, can Determine that transmission path is the second member device that the first member device-is connected to the first member device.By taking Fig. 4 as an example, it is assumed that at The interface (i.e. outgoing interface) that member's equipment 2 is connect with Downlink Switch is available, then member device 1 can determine that transmission path is member Equipment 1 → member device, 2 → Downlink Switch.

If it is determined that the outgoing interface for the second member device being connected with the stacking opening of the first member device is unavailable, then can determine Whether the outgoing interface for another the second member device being connected by stacking opening with second member device can be used.If available, It can determine that transmission path is that the first member device-first the second member device for being connected to the first member device-is connected to the Second the second member device of one the second member device.By taking Fig. 4 as an example, it is assumed that member device 2 is connect with Downlink Switch Interface (i.e. outgoing interface) it is unavailable, member device 3 and interface (i.e. outgoing interface) that afternoon, interchanger was connect are available, then member sets Standby 1 can determine that transmission path is 1 → member device of member device, 2 → member device, 3 → Downlink Switch.

Step 2: obtaining the stacking for sending message with the first VLAN value of outgoing interface binding and with each member device 2nd VLAN value of mouth binding, and the first VLAN value and each 2nd VLAN value are encapsulated according to transmission path to described first The heading of message obtains the first encapsulated message.

Wherein, the first VLAN value is the outgoing interface that the last one member device is connected to external equipment in transmission path VLAN value.

First VLAN value and each 2nd VLAN value are encapsulated according to transmission path to the heading of the first message, obtained The first encapsulated message in outermost VLAN value be the first member device stacking opening the 2nd VLAN value, innermost layer VLAN value For the first VLAN value.

For example, if transmission path is first the second member device-that the first member device-is connected to the first member device It is connected to second the second member device of first the second member device.The then VLAN that the first encapsulated message encapsulates from outside to inside Value is successively are as follows: for connecting second in the 2nd VLAN value of the stacking opening of the first member device, first the second member device 2nd VLAN value of the stacking opening of the second member device, the first VLAN value of the outgoing interface of second the second member device.

By taking Fig. 4 as an example, it is assumed that the interface (i.e. outgoing interface) that member device 2 is connect with Downlink Switch is unavailable, Cheng Yuanshe Standby 3 is available with the interface (i.e. outgoing interface) that afternoon, interchanger was connect, then member device 1 can determine that transmission path is member device 1 → member device, 2 → member device, 3 → Downlink Switch, then the first VLAN value is the VLAN value of the outgoing interface of member device 3 1, each 2nd VLAN value is respectively the VLAN value 3 of the stacking opening 1 of member device 1, the VLAN value 2 of the stacking opening 2 of member device 2. Assuming that the format of the first message is " [target MAC (Media Access Control) address] [source MAC] [protocol type] [data portion] ", by each VLAN value The heading of the first message is encapsulated into according to transmission path, the format of the first obtained encapsulated message is " [target MAC (Media Access Control) address] [source MAC] [VLAN value 3] [VLAN value 2] [VLAN value 1] [protocol type] [data portion] ".

Step 3: determining that the first member device is used for and biography according to first the 2nd VLAN value in the first encapsulated message First stacking opening of first the second member device connection in defeated path.

Wherein, first the 2nd VLAN value is the outermost VLAN value of the first encapsulated message.

Step 4: deleting first the 2nd VLAN value that the first encapsulated message includes, the second encapsulated message is obtained, by second Encapsulated message is sent to first the second member device in transmission path by the first stacking opening.

It wherein, can be according to outermost in the second encapsulated message after first the second member device receives the second encapsulated message The VLAN value of layer determines the interface of transmitting message, and VLAN value outermost in the second encapsulated message is deleted, then by true Fixed interface transmitting message.

It is understood that if first the second member device is not the last one member device in transmission path, The interface of determining transmitting message is the stacking opening for being connected to second the second member device, will be outermost in the second encapsulated message It, can be by stacking opening by message transmissions to second the second member device after the VLAN value of layer is deleted.If first the second member Equipment is the last one member device in transmission path, it is determined that transmitting message interface be outgoing interface.

It is corresponding with a upper embodiment in the scene that stack equipment includes more than two member devices, the embodiment of the present application A kind of message forwarding method is also provided, applied to the second member device in stack equipment, this method specifically includes the following steps:

Step 1: receiving third encapsulated message by local first stacking opening.Third encapsulated message includes the first VLAN value And the 2nd VLAN value of the stacking opening binding of message, the first VLAN value and transmission road are sent with member device each in transmission path The outgoing interface binding of the member device of message is finally received in diameter.The outgoing interface can connect external equipment.

Wherein, the outermost VLAN value in third encapsulated message be second member device on, it is next for connecting The VLAN value of the stacking opening of member device.Innermost layer VLAN value in third encapsulated message is the first VLAN value.Local first heap Folded mouth is connect with a member device upper in transmission path.For the networking shown in Fig. 4, it is assumed that the second member device is member device 2, then local first stacking opening is the stacking opening connecting on member device 2 with stacking opening 1 on member device 1.

Step 2: according to first the 2nd VLAN value that third encapsulated message includes, determine the second member device for Second stacking opening of next member device connection in transmission path.For the networking shown in Fig. 4, it is assumed that the second member device be at Member's equipment 2, then the second stacking opening is the stacking opening 2 connecting on member device 2 with stacking opening on member device 3.

Wherein, first the 2nd VLAN value refers to outermost 2nd VLAN value in third encapsulated message.

Step 3: deleting first the 2nd VLAN value that third encapsulated message includes, the 4th encapsulated message is obtained, by the 4th Encapsulated message is sent to next member device in transmission path by the second stacking opening, so that next member in transmission path Equipment transmits the 4th encapsulated message according to first the 2nd VLAN value in the 4th encapsulated message or the first VLAN value.

Wherein, if next member device in transmission path is the last one member device in transmission path, the 4th The first VLAN value is only included in encapsulated message, it, can be true according to the first VLAN value after which receives the 4th encapsulated message Interface is made, and deletes the first VLAN value in the 4th encapsulated message, obtains the first message, passes through the first report of outgoing interface forwarding Text.This process can be referring particularly to the related embodiment explanation that Fig. 3 is related to.

If next member device in transmission path is not the last one member device in transmission path, which is set It is standby that stacking opening can be determined according to the 2nd VLAN value outermost in the 4th encapsulated message, and delete outermost layer in the 4th encapsulated message The 2nd VLAN value, obtain the 5th encapsulated message, the 5th encapsulated message is transmitted to by stacking opening be connected with itself it is next Member device.

After each member device in subsequent transmission path receives encapsulated message, if the member device is not transmission path In the last one member device, can be according to the method described above according to VLAN value outermost in encapsulated message come transmitting message, directly To the outgoing interface by the last one member device in transmission path by message transmissions to external equipment.If the member device is The last one member device in transmission path, Message processing process can be referring particularly to the related embodiment explanations that Fig. 3 is related to.
