Specific embodiment
In order that those skilled in the art more fully understand the technical scheme in the embodiment of the present invention, and make the present invention real
Apply the above-mentioned purpose of example, feature and advantage can become apparent from understandable, below in conjunction with the accompanying drawings to technical side in the embodiment of the present invention
Case is described in further detail.
Refer to Fig. 1, be a kind of schematic flow sheet of message forwarding method provided in an embodiment of the present invention, as shown in figure 1,
The method may comprise steps of：
It should be noted that in embodiments of the present invention, the executive agent of step 101～step 104 can be stacking system
Any member equipment (referred to herein as target members' equipment) in system, for ease of description, below with step 101～step 104
Executive agent be target members' equipment as a example illustrate.
Step 101, when need by target stacking opening send broadcasting packet when, according to stacking topology determine first instruction letter
Breath, and the broadcasting packet carrying this first configured information is sent by this target stacking opening；Wherein, this first configured information is used for
The member device that this broadcasting packet is forwarded to is forbidden in instruction.
In the embodiment of the present invention, in order to avoid broadcasting packet forms loop, the member in pile system in pile system
Equipment, when sending broadcasting packet, needs to carry in broadcasting packet and forbids that the member that this broadcasting packet is forwarded to sets for instruction
Standby configured information (the referred to herein as first configured information), so that other member device is when receiving this broadcasting packet, root
According to the first configured information carrying in this broadcasting packet, the forwarding of message is controlled.
Wherein, this first configured information can include numbering (the chain heap of the member device that this broadcasting packet passes through
Folded) or the other stacking opening outside sending or forwarding the stacking opening of this broadcasting packet send or the broadcasting packet of forwarding will pass through
Member device (annular stacking).
Correspondingly, in embodiments of the present invention, when target members' equipment needs to send broadcasting packet by target stacking opening
When, this target members' equipment can determine the first configured information according to current stacking topology, and this first configured information is taken
Band sends to the member device that target stacking opening connects in broadcasting packet.
Wherein, target stacking opening refer not to the stacking opening of a certain fixation, but may refer to target members' equipment and take up an official post
One in running order stacking opening.
Specifically it is contemplated that for chain stacking, usual target members' equipment generally only needs to send a broadcasting packet, is
Prevent this broadcasting packet from forming loop in pile system it is only necessary to ensure that this broadcasting packet will not set through same member twice
Standby, therefore, in order to prevent the generation of broadcasting packet loop in chain stacking, the first configured information can include this broadcasting packet warp
Member's numbering of the member device crossed, thus, when other member devices receive this broadcasting packet, will not be again by this broadcasting packet
It is transmitted to the member device of this broadcasting packet process.
For example, taking the stacking scene of chain shown in Fig. 2A as a example, when equipment 1 needs to send broadcasting packet, in order to keep away
Exempt from broadcasting packet and produce loop in pile system, equipment 1 can carry the member's numbering of itself in this broadcasting packet, to refer to
Show that the other member devices receiving this broadcasting packet are forbidden for this broadcasting packet relaying to equipment 1.
And for annular stacking, due to the forwarding road of the different other member devices in pile system of same member device
The exit port in footpath may be different, therefore, when in annular stacking, target members' equipment sends broadcasting packet, it usually needs by two
Stacking opening respectively sends a broadcasting packet.
For example, taking the scene of annular stacking shown in Fig. 2 B as a example it is assumed that equipment 1 arrives the forward-path of equipment 2 and equipment 3
Exit port be stacking opening 11, equipment 1 arrive equipment 4 forward-path exit port be stacking opening 12, then when equipment 1 send broadcast
During message, need respectively to send a broadcasting packet by stacking opening 11 and stacking opening 12.
It can be seen that, in annular stacking scene, in order to avoid broadcasting packet forms loop in addition it is also necessary to avoid in pile system
Target members' equipment is forwarded to the forwarding with another stacking opening as exit port by the broadcasting packet that a stacking opening sends
Other member devices on path, therefore, for annular stacking scene, target members' equipment passes through target stacking opening and sends broadcast
During message, the first configured information can include target members' equipment, and is end with another stacking opening of target members' equipment
Member's numbering of the member device on the forward-path of mouth.
For example, still taking the scene of annular stacking shown in Fig. 2 B as a example, when equipment 1 needs to send broadcast by stacking opening 11
During message, the first configured information carrying in this broadcasting packet can include member's numbering of equipment 1, and with stacking opening 12 is
Member's numbering of the member device (i.e. equipment 2 and equipment 3) on the forward-path of exit port, receives this broadcasting packet to indicate
Other member devices forbid for this broadcasting packet being sent to equipment 1, equipment 2 and equipment 3；In the same manner, equipment 1 needs by heap
When folded mouth 12 sends broadcasting packet, the first configured information carrying in this broadcasting packet can include member's numbering of equipment 1, with
And the member device of the member device (i.e. equipment 4) on the forward-path with stacking opening 11 as exit port, receive this to indicate
Other member devices of broadcasting packet are forbidden for this broadcasting packet being transmitted to equipment 1 and equipment 4.
Step 102, when receiving broadcasting packet, the first configured information according to carrying in this broadcasting packet judges whether
Allow to forward this broadcasting packet to neighbours' member device.If so, go to step 103；Otherwise, go to step 104.
In the embodiment of the present invention, when target members' equipment receives the broadcasting packet that other member devices send or forward
When, target members' equipment needs to obtain the first configured information carrying in this broadcasting packet, and is sentenced according to this first configured information
Break and whether allow to forward this broadcasting packet to neighbours' member device.
For example, taking scene shown in Fig. 2A as a example, when equipment 2 receives the broadcasting packet of equipment 1 transmission, can obtain
Take the first configured information carrying in this broadcasting packet, find that this first configured information includes member's numbering of equipment 1, because
This, equipment 2 determines and does not allow for this broadcasting packet to be transmitted to equipment 1, and allows for this broadcasting packet to be transmitted to equipment 3.
Again for example, taking scene shown in Fig. 2 B as a example, when equipment 4 receives the broadcasting packet of equipment 1 transmission, permissible
Obtain the first configured information carrying in this broadcasting packet, find that this first configured information includes equipment 1, equipment 2 and sets
Standby 3 member's numbering, therefore, equipment 4 determines and does not allow for this broadcasting packet to be transmitted to equipment 1 and equipment 3, that is, equipment 4 is not right
The broadcasting packet receiving is forwarded.
When equipment 2 receives the broadcasting packet of equipment 1 transmission, the first instruction carrying in this broadcasting packet can be obtained
Information, finds that this first configured information includes member's numbering of equipment 1 and equipment 4, and therefore, equipment 2 determines that do not allow should
Broadcasting packet is transmitted to equipment 1, and allows for this broadcasting packet to be transmitted to equipment 3.
Step 103, update the first configured information of carrying in this broadcasting packet according to stacking topology, and wide after updating
Report literary composition and be transmitted to this neighbours' member device.
It is contemplated that the increase of the member device passing through in repeating process with broadcasting packet in the embodiment of the present invention, its
Forbid that the member device being forwarded to also can change, therefore, in the repeating process of broadcasting packet, carry in broadcasting packet
First configured information is also required to adaptively be updated.
Correspondingly, when target members' equipment determines needs according to the first configured information carrying in the broadcasting packet receiving
To opposite equip. forward this broadcasting packet when, target members' equipment needs to update the first instruction letter carrying in this broadcasting packet
Breath.
As a kind of optional embodiment, in embodiments of the present invention, when stacking topology is for annular stacking topology, on
State and the first configured information carrying in this broadcasting packet is updated according to stacking topology, can include：
Member's numbering of this target members' equipment is added in the first configured information.
In this embodiment, if when stacking topology stacks topology for chain, when target members' equipment receives broadcast
Message, and determine that needs forward this broadcasting packet to neighbours' member device according to the first configured information carrying in broadcasting packet
When, itself member numbering can be added in the first configured information for target members' equipment, and by the broadcasting packet after updating
It is sent to neighbours' member device.
For example, still taking the stacking scene of chain shown in Fig. 2A as a example, when equipment 2 receives the broadcast report of equipment 1 transmission
Literary composition, and determine that this is broadcasted by permission according to the first configured information (including member's numbering of equipment 1) carrying in this broadcasting packet
When message is transmitted to equipment 3, before this broadcasting packet is transmitted to equipment 3, equipment 2 needs to add in the first configured information
The member's numbering of itself, the first configured information will be numbered by the member including equipment 1 and is updated to including equipment 1 and equipment 2
Member numbers, and the broadcasting packet after updating is transmitted to equipment 3.
As another kind of optional embodiment, in embodiments of the present invention, when stacking topology is for annular stacking topology,
The first configured information carrying in above-mentioned topology this broadcasting packet of renewal according to stacking, can include：
The member device that first configured information is included is updated to member's numbering of target members' equipment, and with target
The stacking opening that member device receives this broadcasting packet is member's numbering of the member device on the forward-path of exit port.
In this embodiment, if when stacking topology is annular stacking topology, when target members' equipment receives broadcast
Message, and determine that needs forward this broadcasting packet to neighbours' member device according to the first configured information carrying in broadcasting packet
When, the member of itself can be numbered by target members' equipment, and the heap receiving this broadcasting packet with this target members' equipment
Folded mouth is member's numbering of the member device on the forward-path of exit port.
For example, still taking the scene of annular stacking shown in Fig. 2 B as a example, when equipment 2 receives equipment 1 by stacking opening 21
The broadcasting packet sending, and (include equipment 1 and the member of equipment 4 compiles according to the first configured information carrying in this broadcasting packet
Number) determine and allow when this broadcasting packet is transmitted to equipment 3, equipment 2 needs the carry in this broadcasting packet first instruction letter
Breath is updated to the member's numbering of itself, and the forwarding as exit port for the stacking opening (stacking opening 21) to receive this broadcasting packet
Member's numbering of member device on path.Member device on forward-path with stacking opening 21 as exit port on hypothesis equipment 2
Including equipment 1 and equipment 4, then equipment 2 need by the first configured information by include equipment 1 and equipment 4 be updated to including equipment 2,
Equipment 1 and equipment 4.
Step 104, refuse to forward this broadcasting packet to neighbours' member device.
In the embodiment of the present invention, when target members' equipment receives broadcasting packet, and according to carrying in broadcasting packet
When one configured information determination does not allow to forward this broadcasting packet to neighbours' member device, target members' equipment will be refused to become to neighbours
Member's this broadcasting packet of device forwards, to avoid broadcasting packet to form loop in pile system.
For example, still taking scene shown in Fig. 2A as a example, when equipment 4 receives the broadcasting packet of equipment 3 forwarding, this is wide
Report member's numbering that the first configured information carrying in literary composition includes equipment 1, equipment 2 and equipment 3, due to the stacking of equipment 4
Mouth 42 is in off working state, and message will not forward from this stacking opening, and therefore, equipment 4 needs to determine whether by stacking
Mouth 41 this broadcasting packet of forwarding, but because the member device that stacking opening 41 connects is equipment 3, and equipment 4 is believed according to the first instruction
Breath can determine and do not allow to forward this broadcasting packet to equipment 3, and therefore, equipment 4 will not forward this broadcasting packet to equipment 3, from
And avoid broadcasting packet and produce loop in pile system (i.e. broadcasting packet, from equipment 1 through equipment 2 and equipment 3, is forwarded to
After equipment 4, stop forwarding).
Again for example, still taking the scene of annular stacking shown in Fig. 2 B as a example, when equipment 3 receives the broadcast of equipment 2 forwarding
During message (this broadcasting packet is sent by equipment 1), the first configured information carrying in this broadcasting packet include equipment 2, equipment 1 with
And member's numbering of equipment 4, now, equipment 3 is needed to determine whether respectively to be forwarded by stacking opening 31 and stacking opening 32 and is somebody's turn to do
Broadcasting packet.
For stacking opening 31, because the member device that stacking opening 31 connects is equipment 2, and equipment 3 is according to the first instruction letter
Breath can determine and do not allow to forward this broadcasting packet to equipment 2, and therefore, equipment 3 will not forward this broadcasting packet to equipment 2；
For stacking opening 32, because the member device that stacking opening 32 connects is equipment 4, and equipment 3 is according to the first instruction letter
Breath can determine and do not allow to forward this broadcasting packet to equipment 4, and therefore, equipment 3 will not forward this broadcasting packet to equipment 4.
That is, the broadcasting packet that equipment 1 is sent by stacking opening 12, through equipment 2, after being forwarded to equipment 3, equipment 3 is not
May proceed to forward this broadcasting packet.And the broadcast report being sent by stacking opening 11 according to the associated description in above-mentioned flow process, equipment 1
Literary composition, when reaching equipment 4, equipment 4 also will not continue to forward, thus, the broadcasting packet that equipment 1 sends reaches in pile system
All other member device, and avoid the generation of loop.
What deserves to be explained is, in embodiments of the present invention, in order that member device is when receiving broadcasting packet, Neng Gougen
Determine whether to forward this broadcasting packet, stacking system to neighbours' member device according to the first configured information carrying in broadcasting packet
In system, each member device needs pre-recorded each stacking opening and the corresponding relation of member's numbering of neighbours' member device (to remember in advance
Record member's numbering of neighbours' member device that each stacking opening connects)；Wherein, this corresponding relation can be existed by user (as manager)
When carrying out stack arrangement, manual configuration is in each member device it is also possible to dynamically be obtained after forming stacking opening by each member device
Take and record, it implements here and repeats no more.
Further, in embodiments of the present invention it is contemplated that when stacking topology changes, being such as changed into from chain stacking
Annular stacking, or dissolve for chain stacking by annular stack, each member device determines the first configured information when sending broadcasting packet
The mode updating the first configured information when mode or forwarding broadcasting packet is required to change.
Correspondingly, in embodiments of the present invention, when target members' equipment detects stacking topology and changes, need to adjust
The whole mode itself determining the first configured information and the mode updating the first configured information.
For example, when stacking topology becomes annular stacking by chain stacking, target members' equipment can be according to above-mentioned annular
The mode determining the first configured information in stacking scene or the mode updating the first configured information carry out the first configured information really
Determine or update.
In the same manner, when stacking topology dissolves into chain stacking by annular stack, target members' equipment can be according to above-mentioned chain
The mode determining the first configured information in stacking scene or the mode updating the first configured information carry out the first configured information really
Determine or update.
Further, in embodiments of the present invention, when stacking opening shutdown (closing) occurs in annular pile system,
Pile system is it may happen that divide.For example, when the stacking opening 11 of equipment 1 and equipment 3 in the scene of annular stacking shown in Fig. 2 B
During stacking opening 32shutdown, it will stacking splitting occurs, it is split into the chain stacking of equipment 1, equipment 2 and equipment 3 composition,
And equipment 4 (when stacking splitting causes to stack change in topology, the first configured information determines or the change of update mode may refer to
Associated description in above-mentioned flow process).
As stacking opening 32undo (revocation) shutdown of the stacking opening 11 of equipment 1 and equipment 3, if system configuration
Merge (mixing) is not restarted, then equipment 4 will not restart addition stacking automatically, and needs user to be manually added.Join manually in user
Install standby 4 add stacking before, if equipment 1 (equipment 3) will be unable to get, stacking opening 11 (stacking opening 32) connects is stacked into
The numbering of member's equipment, now it is possible that broadcasting packet loop in this pile system.
Therefore, in order to avoid the appearance of the problems referred to above, in embodiments of the present invention, if pile system configuration merge does not weigh
Open, then when stacking topology is annular stacking, and after stacking opening shutdown of target members' equipment, during undo shutdown,
Before sending broadcasting packet, sent by this stacking opening and check message, to carry out port validity checking；Pass through if checking,
Determine that this stacking opening state is UP (working condition), and record member's numbering of the member device of this stacking opening connection；Otherwise, will
The state of this stacking opening is set to Down (off working state).
Wherein, the realization that target members' equipment carries out port validity checking can be：
Target members' equipment by stacking opening to be checked (i.e. after above-mentioned shutdown, the stacking of undo shutdown
Mouthful) send connection request (Connect Request) message to neighbours' member device, if receiving neighbours in Preset Time
What member's equipment returned connection replys (Connect Answer) message, then obtain member's numbering of neighbours' member device further,
If obtaining successfully it is determined that successful connection, i.e. port validity checking is passed through, and sends successful connection to neighbours' member device
(Connect Success) message.If do not receive the return of neighbours' member device in Preset Time connection replys message, or
It is determined that connection failure, i.e. port validity checking is not passed through, and sets to neighbours member for the numbering failure obtaining neighbours' member device
Preparation send connection failure (Connect Failed) message.
Further, in embodiments of the present invention it is contemplated that in annular pile system, if because certain member device power-off is led
Cause stacking opening when being changed into off working state (off working state being changed into from working condition), not direct-connected with this member device other
Member device may perceive this stacking opening in time and be changed into off working state, now it may happen that message dropping.
Therefore, in embodiments of the present invention, when stacking topology is annular stacking, and target members' device-aware is to stacking opening
When being changed into off working state, sent a notification message by another stacking opening of working condition, to notify this another stacking opening to connect
Neighbours' member device there is stacking opening off working state be changed into from working condition, so that this member device updates stacking topology.
It can be seen that, in the method flow shown in Fig. 1, forbid this broadcasting packet by carrying in broadcasting packet for instruction
First configured information of the member device being forwarded to, thus, the other member devices receiving this broadcasting packet can be according to wide
Report the first configured information of carrying in literary composition to determine whether to forward this broadcasting packet to opposite end member, it is to avoid broadcasting packet
Loop is produced in pile system.
In order that those skilled in the art more fully understand technical scheme provided in an embodiment of the present invention, with reference to concrete
Application scenarios are described to technical scheme provided in an embodiment of the present invention.
It should be noted that in this embodiment, with above-mentioned first configured information with the TM-Domain (stream of member device
Amount control domain) ID (mark) (herein with the member of TM-Domain ID identified members' equipment numbering) bitmap (bitmap) value
Form carry between the frame of broadcasting packet communicate head extended field in as a example.
In this embodiment, between due to the frame of certain chip switch transmission stacking during message, need to increase between one layer of frame
Communication head, for carrying the necessary information of message forwarding, therefore, it can be extended by the form of the head that communicates between this frame,
Above-mentioned first configured information is carried in communication head between this frame.
Additionally, in this embodiment, stacking opening in above-mentioned certain chip switch is needed to record this heap in the chips
Member's numbering (herein) of neighbours' member device that folded mouth connects taking TM-Domain ID as a example.
Wherein, when stacking opening is for working condition, the member of neighbours' member device of this stacking opening place chip record compiles
Number for neighbours' member device TM Domain ID；When stacking opening is for off working state, this stacking opening place chip record
The member of neighbours' member device numbers the invalid value being to give tacit consent to, for example, if pile system is maximum supports 8 equipment stackings, then
This default value can be equivalent for 9,10,11.
It is described with reference to the realization that different scenes forward scheme to message provided in an embodiment of the present invention.
First, chain stacking
Taking the stacking scene of chain shown in Fig. 2A as a example, in this scenario, the first configured information carrying in communication head between frame
The bitmap value of the TM-Domain ID of the member device passing through for message, the broadcasting packet that such as equipment 1 sends, through equipment 2,
Arrival equipment 3, its setting value be each member device TM-Domain ID bitmap value, that is, 1,2,3 phases or value (0001 or
0010 or 0100=0111).
Member's numbering of neighbours' member device that each stacking opening records in the chips following (where it is assumed that stacking opening 11,
21st, 31 and 41 it is respectively equipment 1, the first stacking opening of equipment 2, equipment 3 and equipment 4, stacking opening 12,22,32 and 42
It is respectively equipment 1, the second stacking opening of equipment 2, equipment 3 and equipment 4, similarly hereinafter)：
| Member device | First stacking opening | Second stacking opening |
| Equipment 1 | 9 | 2 |
| Equipment 2 | 1 | 3 |
| Equipment 3 | 2 | 4 |
| Equipment 4 | 3 | 11 |
, through equipment 2, reach equipment 3, the first instruction that between frame, communication head carries taking the broadcasting packet that equipment 1 sends as a example
Information be 1,2,3 mutually or bitmap value, the member of neighbours' member device of stacking opening 32 place chip record of equipment 3 numbers
For 4.
When the stacking opening 32 of equipment 3 sends message, the member of neighbours' member device of its place chip record can be numbered
The value phase of the first configured information carrying with heading be worth for 0 (0111 and 1000=0000), then message can be sent to equipment
4.
When equipment 4 receives broadcasting packet, stacking opening 42 is in off working state, and message will not forward from this stacking opening.
But stacking opening 41 is still in working condition, message still can be forwarded from this stacking opening.During forwarding, stacking opening 41 place chip note
To number be 3 to the member of neighbours' member device of record, the value phase of the first configured information carrying with heading be worth for non-zero (0111
With 0100=0100), represent that message passes through equipment 3 forwarded over, then do not allow to be forwarded to equipment 3 again, message is lost.
And then reach chain stacking and prevent the purpose of broadcasting packet loop.
2nd, annular stacking
Taking the scene of annular stacking shown in Fig. 2 B as a example, in this scenario, the first configured information in communication head between frame is to send out
Send the TM-Domain ID of the member device of broadcasting packet, and outside the stacking opening of this broadcasting packet is sent with this member device
Another stacking opening be exit port forward-path on member device TM-Domain ID.
In this scenario, each member device forms heap poststack it is thus necessary to determine that arriving the forward-path of each other member devices.
For example, it is assumed that the forward-path to other member devices that in scene shown in Fig. 2 B, each member device determines is as follows
(being represented with the exit port of forward-path)：
| Member device | Equipment 1 | Equipment 2 | Equipment 3 | Equipment 4 |
| Equipment 1 | ――― | Stacking opening 12 | Stacking opening 12 | Stacking opening 11 |
| Equipment 2 | Stacking opening 21 | ――― | Stacking opening 22 | Stacking opening 21 |
| Equipment 3 | Stacking opening 31 | Stacking opening 31 | ――― | Stacking opening 32 |
| Equipment 4 | Stacking opening 42 | Stacking opening 42 | Stacking opening 41 | ――― |
Wherein, the exit port that in upper table, the bright equipment 1 of the 2nd row the 3rd list arrives the forward-path of equipment 2 is stacking opening 12；…；
The exit port that the bright equipment 4 of 5th row the 4th list arrives the forward-path of equipment 3 is stacking opening 41.
, the member device that the forward-path with stacking opening 11 as exit port reaches is equipment 4, to stack taking equipment 1 as a example
Mouth 12 is the equipment of the forward-path arrival of exit port is equipment 2 and equipment 3.Then equipment 1 sent by stacking opening 11 or turn
The first configured information carrying in the broadcasting packet sent out needs the TM-DomainID including equipment 1, and is with stacking opening 12
The TM-Domain ID of the member device on the forward-path of port, that is, 1,2 and 3, sent by stacking opening 12 or forward is wide
The first configured information carrying in report literary composition needs the TM-Domain ID including equipment 1, and with stacking opening 11 as exit port
Forward-path on member device TM-Domain ID, that is, 1 and 4.The IRF-Port of other equipment is similar to setting.
In this scenario, member's numbering of neighbours' member device that each stacking opening records in the chips is as follows：
| Member device | First stacking opening | Second stacking opening |
| Equipment 1 | 4 | 2 |
| Equipment 2 | 1 | 3 |
| Equipment 3 | 2 | 4 |
| Equipment 4 | 3 | 1 |
