Description
Technical field
The present invention relates to mobile communication technology, particularly a kind of MESH network wireless access point re-accesses method and wireless access point device.
Background technology
At present, the application of wireless network day by day enlarges, and the application of wireless lan (wlan) netted (MESH) network technology also more and more widely.The MESH network of centralized control formula is current common a kind of wireless network architecture, and its typical structure such as Fig. 1 illustrate.Referring to Fig. 1, in the MESH of centralized control formula network, MESH network wireless access point (Mesh Access Point; MP) by access controller (Access Controller; AC) wireless access point control and configuration (Control and Provisioning of Wireless Access Points, CAPWAP) tunnel are set up in unified management and control between MP and AC; AC issues managing control information through CAPWAP tunnel to MP, transmits data message; MP reports running status through CAPWAP tunnel to AC, carries out safety certification and transmission and treats the transit telegram literary composition.As shown in Figure 1; A part of MP in the MESH network is through wired cable access switch or router; Thereby link to each other with AC through cable network, this type of MP be called door MP (MeshPortal Point, MPP); Like the MP1 among Fig. 1, MP2 and MP3, CAPWAP tunnel is set up via cable network between door MP and the AC; Another part MP links to each other with door MP or other MP through the Wireless MESH link, and this type of MP is called common MP, is called for short MP, and like the MP4 among Fig. 1, MP5 and MP6, the part of the CAPWAP tunnel between common MP and the AC must be based upon on the Wireless MESH link.For explaining conveniently, abbreviate common MP as MP, the following stated MP all refers to common MP.
In present MESH network, after the CAPWAP tunnel between MP and the AC was set up, MP got into normal operating condition.Under normal operating condition, MP safeguards the MESH link through sending out protocol massages mutually with other MP or door MP; And, safeguard CAPWAP tunnel through keepalive mechanism between MP and the AC.If in setting-up time, do not receive CAPWAP keep-alive message, then MP judges that CAPWAP tunnel breaks off, and gets into the zero configuration state and needs to carry out the process that re-accesses.Under the zero configuration state, MP removes all configurations that comprise the MESH configuration of self, and breaks off all MESH links, and this moment, MP can not transmit the Any user data, and MESH promptly can not be provided service.MP re-accesses process and comprise safe MESH link is rebuild and rebuild to CAPWAP tunnel that the process that MP re-accesses is following under the zero configuration state:
Step 1, drive sweep.
The signal of MP around MP monitors on all channels of all wave points of self, definite channel position that possibly have the neighbours of oneself.
Step 2, active scan.
MP initiatively sends probe messages according to the result of drive sweep on the channel that neighbours possibly occur, if the other side responds, then the other side MP is labeled as candidate neighbours and notes.
Step 3 is set up interim MESH link.
MP sends the MESH protocol massages to candidate neighbours one by one, initiates the link establishment process, sets up interim MESH link with candidate neighbours.
Step 4 is initiated AC and is sought process.
MP sends the CAPWAP protocol massages through interim MESH link, initiates AC and seeks process.All MESH links are broken off because be in the MP of zero configuration state, so after having only the interim MESH link establishment in the 3rd step, the AC that the CAPWAP agreement is initiated seeks message just might arrive AC, obtains the response of AC.
Step 5 is selected AC and is consulted to set up CAPWAP tunnel.
MP therefrom selects an AC based on the AC response that obtains, and sets up CAPWAP tunnel through sending CAPWAP protocol massages and its negotiation.
Step 6, MP obtains the MESH configuration through CAPWAP tunnel from AC, closes interim MESH link, disposes the MESH link that restarts with neighbours' negotiation to establish safety according to the MESH that obtains from AC.
In said process, the processing time of drive sweep and active scan reaches respectively more than 10 seconds usually.And; If MP can not find oneself AC through interim MESH link in the step 3, then need different with other repeatedly neighbours set up the MESH link, to attempt through other different MESH link discovery AC; If all neighbours that MP has attempted detecting in drive sweep and the active scan; But still do not find the AC of oneself, need come back to drive sweep and active scan process so, survey whether there is other neighbours MP.Said process is carried out repeatedly, rebuilds the used time of CAPWAP tunnel for a few minutes even tens minutes, and is consuming time long, during this period of time the MESH network service disruption of MP.
Under the less-than-ideal situation of environmental condition, for example, in some period, occur in the channel disturbing; Perhaps MP moves at a relatively high speed ceaselessly and perhaps closes the MESH link with MP foundation on every side; The keep-alive message dropping of CAPWAP tunnel often takes place, so MP all can judge the CAPWAP tunnel disconnection with AC both sides under this kind environment, thereby MP must carry out the above-mentioned process that re-accesses; Cause MESH network service disruption a few minutes to tens minute, the poor quality that therefore makes the service of MESH network.

Embodiment
For making the object of the invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, to further explain of the present invention.
It is that MP sets up a kind of configuration protection state that the MP that the present invention proposes re-accesses method;, CAPWAP tunnel gets into the configuration protection state when interrupting; Utilize existing MESH link to attempt recovering and being connected of AC, practiced thrift and existingly re-access drive sweep, active scan, the trial searching neighbours in the method and set up the time that interim MESH link is consumed.
In fact; After MP adds the MESH network, set up safe MESH link, so when causing the CAPWAP tunnel interruption because of the keep-alive message dropping with neighbours on every side; Will save a lot of times if utilize current existing resource to re-access as far as possible; That is, utilize existing MESH link of this MP and the neighbours that set up to recover and being connected of AC, and will not return to the zero configuration state by MP.Therefore, in embodiments of the present invention, on the basis of original normal operating condition of MP and zero configuration state, set up a kind of configuration protection state.
Under the configuration protection state; MP does not close existing MESH link; Need not remove existing MESH configuration yet; But set up the process of CAPWAP tunnel, so can when causing CAPWAP tunnel to interrupt because of CAPWAP keep-alive message dropping, accomplish re-accessing of MP through searching, selection and the negotiation of existing MESH link initiation AC.Under the configuration protection state, MP can continue on existing MESH link, to receive and dispatch message with the maintenance link state, transmits user data.But; Because MP need carry out encrypted negotiation setting up the MESH link according to MESH configuration, and can't obtain the MESH configuration on the AC this moment, dispose newly-built MESH link if go up existing MESH according to MP; Encrypted negotiation possibly can't carry out smoothly; Newly-built MESH link might be dangerous, and therefore, MP no longer sets up new MESH link under the configuration protection state.
After MP and AC consult to set up CAPWAP, sets up successfully for guaranteeing CAPWAP tunnel, can also declare CAPWAP tunnel further logical, if find CAPWAP tunnel set up unsuccessful, being connected of trial foundation and AC again then.
After adding the configuration protection state, the state machine principle schematic of MP is as shown in Figure 2 in the present invention's one preferred embodiment.Referring to Fig. 2, the MP state machine comprises three kinds of states: normal operating condition, zero configuration state and configuration protection state.MP can transform between above-mentioned three kinds of states each other.
Normal operating condition in the embodiment of the invention is identical with the normal operating condition of existing MP, and MP surveys neighbours, through sending out protocol massages foundation mutually and safeguarding the MESH link, safeguards CAPWAP tunnel through keepalive mechanism.
Zero configuration state in the embodiment of the invention is identical with the zero configuration state of existing MP, and employing method of step 1 to step 6 described in background technology re-accesses process.
Interrupt for the CAPWAP tunnel that causes by the keep-alive message dropping between MP and the AC, can adopt the configuration protection state to re-access.Because MP is at electrifying startup or be in the zero configuration state when the restarting first time; This moment, MP detected the CAPWAP tunnel interruption equally; Therefore, can in CAPWAP tunnel, have no progeny further MP state of living in is judged, if be in the zero configuration state; Then adopt with existing zero configuration state under re-access the identical method of method, begin to set up and being connected of AC by drive sweep.If be not in the zero configuration state, then get into the configuration protection state and re-access.Therefore, interrupt, can not carry out this determining step, directly get into the configuration protection state and re-access for the CAPWAP tunnel of confirming to cause by the keep-alive message dropping between MP and the AC.
And, CAPWAP tunnel is first connect after, also might be owing to lead to that the path of AC is real interrupts causing that CAPWAP tunnel interrupts, must adopt being connected of the method that re-accesses foundation and AC under the zero configuration state this moment.Therefore; For making MP can be zero access state from the configuration protection state-transition; Can also be in the embodiment of the invention further for the configuration protection state is provided with the protection timer, CAPWAP tunnel interrupts the back and gets into the configuration protection state, still can not be connected with the AC reconstruction if surpass the setting-up time of this timer; MP will get back to the zero configuration state so, adopt the method that re-accesses under the existing zero configuration state to rebuild and being connected of AC.Equally, interrupt, timer can be set, can under the configuration protection state, accomplish re-accessing for the CAPWAP tunnel of confirming to cause by the keep-alive message dropping between MP and the AC.
Set up the CAPWAP tunnel success through the configuration protection state after, the MESH configuration on the MP at this moment is different with the MESH configuration on the AC, in order to guarantee the fail safe of MESH link; MP obtains the MESH configuration from AC in the embodiment of the invention; And current MESH configuration and the MESH configuration of obtaining from AC compared, if both are inconsistent, then close current whole MESH links; Use new MESH configuration and survey neighbours on every side, rebulid the MESH link.And for the very high system of safety requirements rank, can require MP under any circumstance to rebuild and all obtain the MESH configuration from AC behind the CAPWAP tunnel, and close current whole MESH links, uses new MESH and dispose and rebulid the MESH link.Be sure of the MESH configuration accurately if CAPWAP tunnel is rebuild the back user, then can carry out the process of above-mentioned renewal MESH link, after CAPWAP tunnel is rebuild, directly get into normal operating condition by the configuration protection state.
For after MP is provided with above-mentioned three kinds of states, MP transforms between three kinds of states according to the break-make situation of CAPWAP tunnel each other.When CAPWAP tunnel interrupted, MP got into the configuration protection state by normal operating condition.If the MP that is in the configuration protection state successfully recovers and being connected of AC, then get back to normal operating condition from the configuration protection state in the timer setting-up time; Still can not recover and being connected of AC if surpass the timer setting-up time, then get into the zero configuration state from the configuration protection state.When MP in the zero configuration state and AC rebulid be connected after, MP gets into normal operating condition.
According to above-mentioned improvement to the MP state machine, the present invention proposes a preferred embodiment, and the detailed process that MP is re-accessed method describes, and is as shown in Figure 3, and the process that this method is concrete is following:
Step 301 to step 302 when CAPWAP tunnel interrupts, is judged the current zero configuration state that whether is in, if, execution in step 320; Otherwise, execution in step 303.
Step 303 gets into the configuration protection state, can be simultaneously for MP be provided with the configuration protection sign, and this sign expression MP this moment is in the configuration protection state.
Step 304 starts configuration protection state timer.
Step 305 is safeguarded existing MESH link and is set up CAPWAP tunnel through it.
In this step, MP safeguards existing MESH link, and through existing MESH link establishment CAPWAP tunnel.The specific practice of setting up CAPWAP tunnel is: send the CAPWAP protocol massages through existing MESH link; Initiate AC and seek process; AC is selected in AC response according to obtaining, sends the CAPWAP protocol massages through existing MESH link, consults to set up CAPWAP tunnel with selected AC.
Step 306 judges whether timer is overtime, if, execution in step 320; Otherwise, keep the configuration protection state, execution in step 307.
Step 307 judges whether CAPWAP tunnel sets up success, if continue to keep configuration protection state, execution in step 308; Otherwise, return execution in step 305.
Step 308 is obtained the MESH configuration from AC.
Step 310 is closed existing MESH link, removes existing all MESH configurations, sets up the MESH link according to the MESH configuration of obtaining from AC.
For step 308 to step 310, embodiment according to the invention considers the fail safe of MESH link and re-accesses speed, proposed a kind of preferred forms.The user is being be sure of MESH disposes when correct, can be after step 307 confirm that CAPWAP tunnel is successfully set up, direct execution in step 311.Perhaps, in the system higher, can after step 308, not carry out the comparison deterministic process of step 309, and direct execution in step 310 rebulids the MESH link according to the MESH configuration of obtaining from AC to security level required.
Step 311 withdraws from the configuration protection state, removes the configuration protection sign, closes configuration protection state timer.
Step 312 gets into normal operating condition.
Step 320 gets into the zero configuration state, under the zero configuration state, accomplishes the process that re-accesses.
It is identical with existing step 1 to the step 6 that re-accesses in the method under the zero configuration state, to accomplish the process that re-accesses, and specifically comprises the steps 3201 to 3206:
Step 3201, drive sweep.
The signal of MP around MP monitors on all channels of all wave points of self, definite channel position that possibly have the neighbours of oneself.
Step 3202, active scan.
MP initiatively sends probe messages according to the result of drive sweep on the channel that neighbours possibly occur, if the other side responds, then the other side MP is labeled as candidate neighbours and notes.
Step 3203 is set up interim MESH link.
MP sends the MESH protocol massages to candidate neighbours one by one, initiates the link establishment process, sets up interim MESH link with candidate neighbours.
Step 3204 is initiated AC and is sought process.
MP sends the CAPWAP protocol massages through interim MESH link, initiates AC and seeks process.All MESH links are broken off because be in the MP of zero configuration state, so after having only the interim MESH link establishment in the 3rd step, the AC that the CAPWAP agreement is initiated seeks message just might arrive AC, obtains the response of AC.
Step 3205 is selected AC and is consulted to set up CAPWAP tunnel.
MP therefrom selects an AC based on the AC response that obtains, and sets up CAPWAP tunnel through sending CAPWAP protocol massages and its negotiation.
Step 3206, MP obtains the MESH configuration through CAPWAP tunnel from AC, closes interim MESH link, disposes the MESH link that restarts with neighbours' negotiation to establish safety according to the MESH that obtains from AC.
Adopt above-mentioned MP to re-access method, need improve the MP equipment inner structure, below according to preferred embodiment shown in Figure 4, the MP equipment inner structure of the embodiment of the invention is explained.
