Detailed description of the invention
Below with reference to accompanying drawing and describe the present invention in detail in conjunction with the embodiments.It should be noted that do not conflicting
In the case of, the embodiment in the application and the feature in embodiment can be mutually combined.
Fig. 3 is distributed aggregated link method flow diagram according to embodiments of the present invention, as it is shown on figure 3, this flow process is main
Comprise the following steps (step S302-step S304):
Step S302, obtains the unified distributed aggregated link system banner ID of multiple equipment of local terminal；
Step S304, is sent to opposite end by distributed aggregated link system identifier, according to distributed aggregated link system identifier with
Opposite end carries out distributed aggregated link negotiation.
In step s 302, one of unified mode of distributed aggregated link system identifier of multiple equipment obtaining local terminal
It is: first for the system identifier that multiple equipment configuration of local terminal is same, then using identical system identifier as distributed aggregated link system
System ID, is unified distributed aggregated link system identifier realizing the system identifier of all devices of local terminal.Wherein, this is corresponded to
Multiple equipment of end configure identical system identifier and may include that the multiple equipment into local terminal configure the medium access of identical system
Control the priority of (MAC) and identical system, using the MAC of identical system with the priority of identical system as identical
System identifier.
Preferably, the two of the mode of the unified distributed aggregated link system identifier of multiple equipment of acquisition local terminal are: first
A first selected main equipment in multiple equipment of local terminal, is sent to the first notice message carrying the system identifier of main equipment
Other equipment in addition to main equipment in multiple equipment of local terminal, are judging that miscellaneous equipment is successfully received the first notice message
In the case of, determine distributed aggregated link system identifier according to the system identifier of the main equipment carried in the first notice message.Wherein,
One notice message also includes: the mark of configuration distributed aggregated link system identifier, when miscellaneous equipment is successfully received the first notice
After message, first resolving the first notice message, main equipment is by the mark further according to configuration distributed aggregated link system identifier
System ID is as self distributed aggregated link system identifier, further, it is determined that self distributed of all devices of local terminal
Link aggregation system ID is all updated to the system identifier of main equipment, using the system identifier of main equipment as the distribution of all devices of local terminal
Formula link aggregation system ID.
Preferably, the three of the mode of the unified distributed aggregated link system identifier of multiple equipment of acquisition local terminal are: this
Each equipment in multiple equipment of end second leads to what the neighbouring device that is adjacent sent the system identifier carrying himself
Know message, neighbouring device receives the second notice message, according to the decision rules pre-set to carrying in the second notice message
System identifier carries out trade-off decision with the system identifier of neighbouring device self, is determined for compliance with the system identifier of decision rules, and wherein, decision-making is advised
Then for selecting maximum or the minima of system identifier, after all devices of local terminal all carries out trade-off decision, determine the institute of local terminal
There is maximum system ID or minimum system ID that equipment has as distributed aggregated link system identifier.It should be noted that
The all devices of local terminal all carries out trade-off decision and refers to all to carry out between each two equipment in multiple equipment of local terminal mutual
Second message notifying.
Such as, in actual applications, above-mentioned three kinds obtain distributed aggregated link system identifiers mode can particularly as follows:
Mode one, many employing human configuration modes.In the manner, system MAC of all devices and system priority are all
All can be configured to identical by system MAC and system priority by human configuration, identical system MAC is with identical
System priority i.e. constitutes identical system identifier (System ID).As can be seen here, it is necessary to by all distributed links of local terminal
The system identifier of the consulting device of paradigmatic system is all configured to identical system identifier, certainly, for the ease of implementing, it is also possible to by opposite end
The system identifier of consulting device of all distributed aggregated link systems be all configured to identical system identifier, but, the institute of local terminal
Have the system identifier of equipment associate with the system identifier of opposite end all devices, it is only necessary to the system identifier of all devices of local terminal with
The system identifier of opposite end all devices is separate, it is of course also possible to be identical, for local terminal or opposite end,
Every consulting device all uses the identical system identifier of configuration as distributed aggregated link system identifier, thus carries out distributed chain
Road polymerization is consulted.
Mode two, by selected main equipment, is informed other equipment by main equipment by its system identifier communication, so that the institute of local terminal
There is equipment all to receive the system identifier of main equipment, and this system identifier is defined as distributed aggregated link system identifier.In the manner,
Can be by the system identifier of one main equipment of specified configuration, after each equipment room sets up communication link, main equipment literary composition of transmitting messages disappear
Breath informs configuration neighbouring device, after neighbouring device receives master system ID, and the system identifier of the main equipment in acquisition message, and
As the system identifier of distributed aggregated link, forward the message to neighbor device simultaneously.So, local terminal all devices
All use system identifier that main equipment configures as the system identifier of distributed aggregated link.
Mode three, goes out the system identifier of distributed aggregated link by the communication mode decision-making of dynamic negotiation.In the manner,
Need to initially set up communication link between the multiple devices of local terminal, here, concrete communication link method for building up can set up two
Layer link, it is also possible to set up three layers of link, thus each neighbouring device can mutually communication two-by-two.Specifically, every equipment will be from
Oneself system identifier is advertised to adjacent equipment, and neighbouring device receives after message further according to the system identifier in message and oneself equipment
ID carries out decision-making, and with the form of message, the system identifier obtained after decision-making is sent to its neighbouring device, wherein, the choice of system identifier
Using certain rule, this rule is pre-configured with, for example, it is possible to as required the minimum system MAC in employing equipment and
Minimum system priority is as the System ID of distributed aggregated link, it would however also be possible to employ maximum system MAC in equipment and
Maximum system priority is as the System ID of distributed aggregated link.Generally, can set one stabilization time threshold value,
If in threshold time, the system identifier of all devices decision-making the most no longer changes, and the decision-making of distributed system ID is described out,
Can use for distributed aggregated link.
Below in conjunction with Fig. 4, Fig. 5, aforesaid way two and mode three are described in detail.
Fig. 4 be according to embodiments of the present invention by the main equipment selected by communication inform configuration other equipment in the way of formed
The flow chart of distributed aggregated link system identifier, as shown in Figure 4, this flow process comprises the following steps:

Go to S404；
S404, it is judged that whether this equipment is main equipment, if it is, go to S406, otherwise goes to S408；
S406, this equipment is main equipment, using the system identifier of this equipment as the system identifier of distributed aggregated link and fixed
The transmission system identifier configuration message of phase, to other equipment, is chosen as 3 seconds transmission cycles, goes to S404 in the present embodiment；
S408, non-main equipment, it may be judged whether receive the system identifier configuration message that main equipment sends over；If it is, go to
S410, otherwise goes to S412；
S410, receives the system identifier configuration message that main equipment sends over, and analytic message, by the distributed link of this equipment
The configuration system identifier that paradigmatic system ID is set in message, is transmitted to other equipment by the message received simultaneously, goes to S408,
Continue to determine whether to receive message；
S412, does not receive the system identifier configuration message that main equipment sends over, and needs detection to receive message the most overtime,
Detect three times of messages to send in the cycles (3*3,3 second cycle be only for example) and whether receive message, if it does not, go to S414, if
It is to go to S408, continues to determine whether to receive message；
S414, illustrates to receive message overtime, and link or equipment occur abnormal, now carries out time-out abnormality processing: remove and divide
Cloth link aggregation system ID.Go to S408, rejudge and whether receive message.
As can be seen here, in the manner, it is necessary first to a selected equipment, as main equipment, sets up each equipment room simultaneously
Communication link, main equipment notifies other equipment configuration system identifier identical with main equipment with message mode.At non-main equipment (i.e.
Other equipment outside main equipment) receive message before, owing to distributed aggregated link system identifier does not determine, so not carrying out point
Negotiation between local terminal and opposite end in cloth link aggregation system, only other equipment (the most non-main equipment) receive main equipment and send
System identifier after, the system identifier of distributed aggregated link can be determined.Generally, the message that main equipment sends at least wraps
Containing following information: (1), configuration distributed system ID mark；(2), the system identifier information of main equipment.
Fig. 5 is the flow process that communication mode dynamic negotiation according to embodiments of the present invention forms distributed aggregated link system identifier
Figure, as it is shown in figure 5, this flow process comprises the following steps:
S502, initializes, sets up the communication link of equipment room.Decision system MAC and the default value of decision system priority
Initialize: decision system MAC and decision system priority are initialized as system MAC and the system priority of this equipment, go to
S504；
S504, it is judged that send whether the message cycle arrives, the cycle of the present embodiment is 1 second (within 1 second, being only for example value), if
It is to go to S506, otherwise goes to S508；
S506, send the message cycle to, this equipment decision-making system MAC and decision system priority are sent to adjacent setting
Standby, go to S504, continue detection and wait that message sends；
S508, it may be judged whether receive the message that neighbouring device sends over, if it is, go to S510, otherwise goes to S512；
S510, receive that main equipment sends over decision system MAC and the message of decision system priority, update this
Decision system MAC of equipment and decision system priority, analytic message, compare decision system MAC in message, and decision system is excellent
First level and system MAC of this equipment oneself, system priority size, in the present embodiment, system MAC and system that adopted value is little are excellent
First level, as decision system MAC and the decision system priority of this equipment, naturally it is also possible to big the tying as decision-making of adopted value
Really, S516 is gone to；
S512, does not receive the message that neighbouring device sends over, and needs detection to receive message the most overtime, it is judged that three times
Whether message receives message in the transmission cycle, if it does not, go to S514, if it is, go to S504；
S514, illustrates to receive message overtime, and link or equipment occur abnormal, now carries out time-out abnormality processing: remove and divide
Cloth link aggregation system ID, goes to S504；
S516, it is judged that in continuous 1 minute, system MAC of local device decision-making is the most consistent with decision system priority not to be had
Change, if it is inconsistent, go to S518, otherwise goes to step to S520；
S518, illustrates that the decision-making of system identifier is not the most stable, decision-making successful distributed aggregated link system before removing
ID, goes to S504；
S520, illustrates that system identifier decision-making has been stablized, and takes system identifier (decision system MAC and the decision-making system of this equipment decision-making
System priority) as the system identifier (system MAC and system priority) of distributed aggregated link, go to S504, restart inspection
Survey, prevent the abnormal appearance of link.
As can be seen here, for scheme three, communication mode dynamic negotiation is formed.Dynamic negotiation mode is also required between equipment build
Vertical communication link.But need not specify a main equipment.The system identifier result of oneself decision-making is all passed through message by every equipment
It is sent to adjacent equipment.Every equipment all carries out decision-making according to the system identifier of the system identifier and oneself equipment that receive message.
Message the most mutually sends, and after waiting certain time, reaches steady statue, and the system identifier of every equipment decision-making is all consistent, and will
This system identifier is as the system identifier of distributed aggregated link.The minimum data below that comprises of message that equipment room is mutual: decision-making be
System MAC, the system priority of decision-making.
