The method comprises the steps as follows: after local Radio is added to a Mesh aggregation group, a local MP sends a Mesh message to an end on MP; when receiving the Mesh message sent by the end on MP via the local Radio, the local MP automatically confers that whether a Mesh link between the local Radio and the end on Radio meets preset Mesh link aggregation method with the end on MP, if yes, the Mesh link between the local Radio and the end of Radio is added to the Mesh aggregation link between the local MP and the end on MP.
Description
Technical field
The present invention relates to the network communications technology, particularly wireless mesh (Mesh) link aggregation method and Mesh network access point (MP:Mesh AP).
Background technology
Mesh network is a kind of new wireless local area network-type, with WLAN unlike, the AP (hereinafter referred to as MP) in Mesh network is wireless connections, and, the wireless link of multi-hop can be set up between MP.Along with the increase day by day of Mesh network scale, the Mesh network that fat (Fat) AP forms is faced with serious management bottleneck, and the Mesh network under thin (Fit) AP framework becomes optimum scheme.
In Mesh network under Fit AP framework, Mesh link is set up in units of Mesh service, namely keeper is in wireless controller (AC:Access Controller) upper configuration Mesh service, the Mesh issuing configuration by AC serves in fact for carrying the MP that this Mesh serves, and can unify other MP that Mesh serves and sets up Mesh link (Link) with around carrying this after MP receives Mesh service.As in Fig. 1, keeper binds with MPP1, MPP2, MAP1 and MAP2 by configuring Mesh service 1 on AC, can set up the Mesh Link of 5 shown in Fig. 1, be respectively: MeshLink1 to MeshLlink5.Can find out, between the Mesh service of the upper configuration of AC and MP, the actual Mesh Link set up is the relation of one-to-many.
But, between the MP with Double RF (Radio), if MP has bound identical Mesh service, network topology is as shown in Figure 2 or Figure 3 produced possibly between these two MP, namely in Fig. 2, the Radio2 of Radio1 and MP1 of MP1 sets up Mesh Link with Radio1 and Radio2 of MP2 respectively simultaneously, and in Fig. 3, the Radio2 of MP1 sets up Mesh Link with Radio1 and Radio2 of MP2 simultaneously.And in practical application, in Fig. 2 or Fig. 3, the Radio that Radio2 and the MP2 only needing one of them Radio such as Radio1 of Radio1 and the MP2 of MP1 to set up Mesh Link and MP1 is left such as sets up Mesh Link between Radio2, the network topology shown in Fig. 2 or Fig. 3 obviously can increase the complexity setting up Mesh aggregation group even cannot set up Mesh aggregation group.
In addition, in Mesh network, Mesh Link between MP is only towards the MAC Address of Radio on MP, like this, when a MP exists multiple neighbours MP, Mesh Link can be set up with the Radio on each neighbours MP, but, it only can identify the MAC Address of the Radio setting up Mesh Link with it, but can not identify which MP this Radio belongs to.As shown in Figure 4, there is neighbours MP in MP3, be respectively MP1 and MP2, Mesh Link1 and Mesh Link3 is established for the Radio1 of MP3 and MP1 in Fig. 4 (MAC Address is for MAC1) and Radio2 (MAC Address is for MAC2), then, MP3 only knows itself and MAC Address to be the Radio of MAC1 and MAC Address is that the Radio of MAC2 establishes Mesh Link1 and Mesh Link3 respectively, whether the opposite end of its None-identified MeshLink1 and Mesh Link3 belongs to same MP, and this will cause MP3 can not add the Mesh Link of Mesh aggregation group by selecting properly.Such as, as shown in Figure 4, Mesh Link2 and Mesh Link3 may be put into same Mesh aggregation group by MP3, also Mesh Link1 and Mesh Link4 may be put into same Mesh aggregation group, and in fact only have the Mesh Link1 in Fig. 4 and Mesh Link3 to put into same Mesh aggregation group, and Mesh Link2 and Mesh Link4 puts into same Mesh aggregation group and is only correct Mesh link aggregation.
In order to overcome the above problems, current mechanism is exactly on local Radio, manually specify opposite end Radio to set up Mesh aggregated links, and this can increase configure and maintenance workload in the Mesh network that there is a large amount of MP, lacks flexibility.
Summary of the invention

Below method provided by the invention is analyzed:
Be method flow diagram provided by the invention see Fig. 5, Fig. 5.As shown in Figure 5, the method comprises the following steps:
Step 501, local MP, after local radio frequency Radio adds Mesh aggregation group, sends Mesh message to opposite end MP.
When local Radio adds Mesh aggregation group and adds which Mesh aggregation group by being configured realization in advance on local MP.
In addition, in the present invention, Mesh message can be the protocol massages of Control Cooling.
Step 502, when local MP receives by local Radio the Mesh message that opposite end MP sent by opposite end Radio, and whether the Mesh link that opposite end MP auto negotiation goes out between local Radio and opposite end Radio meets the Mesh link aggregation condition preset, if so, the Mesh link between local Radio and opposite end Radio is added to the Mesh aggregated links (Mesh-Aggregation Link) between local MP and opposite end MP.
Negotiation in this step 502 depends on the following information that Mesh message carries: the added Mesh aggregation group mark of MP mark, Radio mark and Radio.Below by Fig. 6, step 502 is described in detail:
Be the step 502 realization flow figure that the embodiment of the present invention provides see Fig. 6, Fig. 6.As shown in Figure 6, this flow process can comprise the following steps:
Step 601, local MP receives the Mesh message of opposite end MP by opposite end the one Radio transmission by a local Radio.
In this step 601, opposite end the one Radio sends Mesh message and sends after opposite end the one Radio adds Mesh aggregation group, its Mesh message sent expands on existing Mesh message basis, and it comprises following mark: the mark of the mark of opposite end MP, the mark of opposite end the one Radio and the added Mesh aggregation group of opposite end the one Radio.
Certainly, if local MP receives the existing Mesh message that opposite end MP is sent by opposite end the one Radio, then think that opposite end the one Radio is current and do not add Mesh aggregation group, then do not perform Mesh aggregated links flow process of the present invention, carry out according to existing mode, such as, according to the Mesh link etc. between the local Radio and opposite end the one Radio of the processing mode process of existing Mesh link.
Step 602, the Mesh aggregation group mark that local MP carries according to the Mesh message that opposite end the one Radio sends determines the added Mesh aggregation group of opposite end the one Radio, judge that whether a local Radio added Mesh aggregation group is consistent with this opposite end the one Radio added Mesh aggregation group, if not, step 603 is performed.
Step 603, check that the MP mark that the Mesh message that opposite end the one Radio sends carries determines opposite end MP, judge whether opposite end MP establishes Mesh aggregated links with following MP: the MP residing for other Radio adding same Mesh aggregation group except local MP and with a local Radio, if not, step 604 is performed.
Wherein, the MP residing for other Radio adding same Mesh aggregation group except local MP and with a local Radio can be known by asking AC by local MP.
Step 604, judges whether local MP establishes Mesh aggregated links with opposite end MP, if so, performs step 605, otherwise, perform step 608.
Step 605, checks that opposite end the one Radio mark that the Mesh message that opposite end the one Radio sends carries determines opposite end the one Radio.
Step 606, judges whether the upper Mesh link except the Radio of opposite end the one between arbitrary Radio of a local Radio and opposite end MP belongs to the Member Link between local MP and opposite end MP in Mesh aggregated links, if not, and execution step 607.
Wherein, the arbitrary Radio on the MP of opposite end except the Radio of opposite end the one can be known by request AC by local MP.
Step 607, whether the Mesh link judging on opposite end the one Radio and local MP except a local Radio between arbitrary Radio belongs to the Member Link between local MP and opposite end MP in Mesh aggregated links, if not, then performs step 609.
Step 608, judges whether local MP establishes Mesh aggregated links with following MP: the MP residing for other Radio adding same Mesh aggregation group except the MP of opposite end and with opposite end the one Radio, if not, then performs step 609.
Above step 604 to step 608 be according to local MP whether and this opposite end MP establish Mesh aggregated links and determine whether the Mesh link between a local Radio and opposite end the one Radio meets the concrete operations of described Mesh link aggregation condition.
Preferably, in above-mentioned steps 602 to step 603, in step 606 to 608, if judged result is yes, then do not perform Mesh aggregated links flow process of the present invention, perform Mesh link processing etc. according to the processing mode of existing Mesh link.
Step 609, judges whether local MP exists the list item for Mesh aggregated links between local MP and opposite end MP, if not, performs step 610, if so, performs step 611.
Step 610, newly-built Mesh aggregated links between local MP and opposite end MP, and the list item set up for this newly-built Mesh aggregated links, the Member Link of the Mesh link between a local Radio and opposite end the one Radio as newly-built Mesh aggregated links is recorded in the list item of this newly-built Mesh aggregated links.
Step 611, Mesh link between a local Radio and opposite end the one Radio is added to Mesh aggregated links between local MP and opposite end MP as Member Link, and the Mesh link between a local Radio and opposite end the one Radio is recorded to the Mesh aggregated links list item of this existence.
In step 610 or step 611, Mesh link between a local Radio and opposite end the one Radio is recorded to Mesh aggregated links list item specifically can be: by the mark of the aggregation group that the mark of the mark of a local Radio, opposite end the one Radio, the mark of local MP, the mark of opposite end MP and opposite end the one Radio add, be recorded to Mesh aggregated links list item together.Wherein, when comprising following mark in the Mesh aggregated links list item in local MP: on the mark of local MP, the mark of opposite end MP and opposite end MP during the mark of the aggregation group that arbitrary Radio adds, represent to there is Mesh aggregated links between local MP and opposite end MP, also represent that on local MP, existence is for the list item of Mesh aggregated links between local MP and opposite end MP.
Wherein, for ease of Mesh link aggregation, if when the Radio on same MP will add aggregation group, generally all add same aggregation group.So, judgement in step 609 can be: using following mark as keyword: the mark of the aggregation group that the mark of local MP, the mark of opposite end MP and opposite end the one Radio add, search local MP and whether there is the Mesh aggregated links list item comprising this keyword, if, then determine that local MP exists the list item for Mesh aggregated links between local MP and opposite end MP, otherwise, determine that local MP does not exist the list item for Mesh aggregated links between local MP and opposite end MP.
