Background technology
WLAN provides a kind of wireless connections service of local area network (LAN), because wireless data access at a high speed can be provided, WLAN is one of relatively more popular technology of present IT industry, also is popular wireless access way.WLAN adopts centralized AC-AP (Access Controller-Access Point, access controller-access point) framework usually.Wherein, AC provides the centralized management of wlan network, and AP then by setting up link with AC, behind the adding wlan network, provides the wireless access service.
Define concentrated WLAN framework in the existing C APWAP agreement, described the division of WLAN function on AP equipment and AC equipment.The CAPWAP agreement has also defined the communication protocol between AP and the AC.At present, though the communication protocol CAPWAP between AC-AP also among revision, basic framework has been determined, needs to seek earlier AC after AP powers on that is:, sets up CAPWAP tunnel.If AC is interconnected with two layers of AP, then can find AC by broadcasting packet; If AC is interconnected by three layers with AP, then need be by other agreements such as DHCP (Dynamic Host Configuration Protocol, DHCP), DNS (Domain Name Server, name server) obtains the information of AC, sets up CAPWAP tunnel with AC then.
As shown in Figure 1, according to existing C APWAP agreement, existing system comprises: access point AP, access controller AC and DHCP/DNS server.Access point AP search access controller AC detailed process is as follows:
Step 101: access point AP successfully starts and initialization;
Step 102:AP distributes by static configuration, Dynamic Host Configuration Protocol server or configuration automatically (as, IPv6 stateless address configuration), obtains self IP address;
Step 103:AP sends broadcasting and finds the AC message;
Step 104:AP waits for and finds the AC response message;
Step 105:AP judges whether successfully to find AC,, whether receives the discovery AC response message that AC sends that is, if receive, then execution in step 109, otherwise, execution in step 106;
Step 106:AP obtains the IP address of AC from the DHCP/DNS server, as, AP obtains the domain-name information of AC earlier from Dynamic Host Configuration Protocol server, according to the AC domain-name information that obtains, obtain the IP address of AC again from dns server;
Step 107:AP sends clean culture and finds the AC message according to the IP address of the AC that obtains;
Step 108:AC responds and finds the AC response message;
Step 109:AP determines the AC that will insert, sets up the mapping relations of the IP of the IP of AP and AC, then, sets up CAPWAP tunnel.
By said process, we can see that AP seeks AC earlier on double layer network, seek less than AC, then continues to seek AC by the three-layer network mode on double layer network, and Fu Za discovery procedure causes finding the overlong time of AC like this; In addition, under the automatic situation about disposing of the stateless of IPV6, be not need the DHCP/DNS server in fact in the system, that is to say that under the situation of not supporting the DHCP/DNS server, AP can not find AC by three-layer network, as seen, this networking that has limited WLAN is greatly used.
