Here exemplary embodiment will be illustrated in detail, its example is illustrated in the accompanying drawings.Following description is related to
During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represent same or analogous key element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the application.On the contrary, they be only with it is such as appended
The example of the consistent apparatus and method of some aspects be described in detail in claims, the application.
The AC disposed beyond the clouds is referred to as cloud AC, and AP needs to be connected with cloud AC by internet.Such as the framework of Fig. 1 examples,
It can be set in data center 11:Cloud AC12 and certificate server 13, wherein, certificate server 13 can include aaa server
131st, Portal server 132 etc..AP can be connected by internet and gateway with cloud AC12, for example, such as Fig. 1 examples,
AP14 and AP15 is connected on gateway 16, and AP17 connections gateway 18, gateway 16 all connects cloud with gateway 18 by internet19
AC12, so as to which AP14, AP15 and AP17 can also be connected by the gateway and internet19 each connected with cloud AC12.
In this example, it can include in cloud AC12:Primary control AC (Anchor AC) 121 and at least one internal AC
(Inner AC), for example, internal AC122, internal AC123 and internal AC124, can include most certainly, in cloud AC12
The inside AC of amount.Each internal AC can be connected with primary control AC 121 and certificate server 13 respectively.
In order to save the AC quantity in cloud AC it is more when to the occupancy of public network IP address resources, in this example, can set
Primary control AC 121 in cloud AC takes a public network IP address, and each internal AC and is not take up public network IP, and internal AC has private network
IP address, it can be by interacting between the private network IP address and primary control AC or certificate server.Therefore, in cloud AC,
No matter the number of internal AC quantity, all only takes up a public network IP address.
Fig. 2 illustrates the flow chart of AP connection control methods, and this method can be performed by the primary control AC in cloud AC, such as Fig. 2
Shown, this method can include:
Step 201, the discovery request message that AP is sent is received, and is that AP distributes AC according to pre-defined rule.
In this example, all AP can when dispatching from the factory preset primary control AC domain name or IP address.By taking preset domain name as an example,
Such as the AP14 in Fig. 1 can be searched and led by the domain name for the primary control AC 121 for being preset at device interior through dns server
Control the public network IP address of AC121 IP address, i.e. primary control AC 121.AP14 can be according to the IP address of primary control AC 121, to master control
AC121, which is sent, finds request message (Discovery Request Message).
Primary control AC 121 can be that AP14 distributes AC, the AC distributed can be after above-mentioned discovery request message is received
One of internal AC, or can also be primary control AC in itself.Wherein, whether primary control AC or internal AC can use end
Slogan identifies, and primary control AC 121 can run hash algorithm according to AP14 information and obtain one when receiving discovery request message
Individual port numbers, and primary control AC corresponding to the port numbers or internal AC are selected, AP14 is distributed to, is allowed to establish connection with AP14.
In this example, primary control AC 121 can be that each internal AC of connection distributes an agent side slogan, and different is interior
Portion AC has different agent side slogans.The method of salary distribution of the agent side slogan is not limited, for example can be randomly assigned, or
Distribution etc. can also be incremented by.Primary control AC 121 can by internal AC private network IP address, internal AC incoming end slogan (i.e. and AP
Interactive protocol port number, internal AC can monitor the inside end slogan and wait AP connections) and internal AC agent side slogan
Between corresponding relation, be stored in the address conversion list item of primary control AC 121.Such as table 1 below, illustrate in a kind of primary control AC 121
Address conversion list item:
The address conversion list item of the primary control AC of table 1
Each internal AC above-mentioned corresponding relation can be stored in primary control AC 121, and in the discovery for receiving AP14 transmissions
During request message, AP14 is distributed to by the internal AC of selection one in multiple internal AC according to pre-defined rule.Primary control AC 121 is AP14
When distributing internal AC, the pre-defined rule of institute's foundation can have a variety of, and this example is not limited, for example, can be according to AP14 AP
Identify (mark can be AP name), perform Hash and obtain the agent side slogan, and the proxy port that Hash is obtained
Internal AC distributes to AP14 corresponding to number.Or Hash is carried out according to AP14 IP address and obtains agent side slogan, select the generation
Manage internal AC corresponding to port numbers;Or it can also be closed according to the AP14 configured in advance in primary control AC 121 is corresponding with AC
System, determines AC corresponding to AP14, you can be according to business needs, specifies by some AP distribution under some AC, such as, will
AP and an internal AC are corresponding or corresponding with primary control AC.
In this example, it is assumed that primary control AC is that the AC that AP is selected is internal AC according to pre-defined rule, then continues executing with step
202。
Step 202, when the AC of distribution is internal AC, returned to the AP and carry the primary control AC as described internal AC points
The agent side slogan and the discovery response message of the public network IP address of the primary control AC matched somebody with somebody.
For example, primary control AC 121 after above-mentioned discovery request message is received, one can be returned to AP14 and finds response report
Literary (Discovery Response Message), is carried in the response message:The public network IP address of primary control AC 121 and
It is in step 201 agent side slogan corresponding to the inside AC of AP14 distribution.
Step 203, the connection request message that AP is sent is received, the connection request message includes:The generation of the internal AC
Manage port numbers and the public network IP address.
In this example, AP14 can report when receiving the discovery response message of the transmission of primary control AC 121 according to response is found
The IP address for the primary control AC 121 that text includes sends connection request message to primary control AC 121, and foregoing discovery is carried in message and is rung
The agent side slogan for the inside AC that message includes is answered, connection is established with internal AC corresponding with the agent side slogan.
Step 204, according to address transformation table entries, the agent side slogan in the connection request message is replaced with described
Portion AC incoming end slogan, the inside is transmitted to after the public network IP address is replaced with into the private network IP address of the internal AC
AC, connected with causing the internal AC to be established according to the connection request message received with the AP.
For example, after primary control AC 121 receives the connection request message of AP14 transmissions, can be stored according to primary control AC 121
Address conversion list item, the agent side slogan carried in connection request message is replaced with to corresponding internal AC incoming end slogan, can
To obtain incoming end slogan corresponding to agent side slogan by inquiring about local address conversion list item;Can also be by connection request report
The public network IP address of primary control AC 121 in text replaces with corresponding internal AC private network IP address, and the private network IP address can also lead to
Cross local address conversion list item and obtain private network IP address corresponding to agent side slogan.
After above-mentioned conversion is carried out, the connection request message after conversion can be transmitted to corresponding inside by primary control AC 121
AC, connected with causing corresponding internal AC to be established according to the connection request message received with AP14.For example, corresponding internal AC is received
To after foregoing connection request message, it can establish and connect according to old process and AP14.
The AP connection control methods of this example, by the way that cloud AC is arranged into the framework that primary control AC connects with internal AC, and
Only primary control AC takes public network IP address, and internal AC uses private network IP, and AP connection request is forwarded to inside by primary control AC
AC, this mode are all hidden in inside cloud AC equivalent to by internal AC, and cloud AC is externally interacted by primary control AC with external network, cloud
AC only takes up a public network IP, no matter internal AC quantity, will not increase the occupancy to public network IP resource, so as to save
IP address resource is saved.
In aforesaid way, each internal AC inside cloud AC shares the public network IP address that identical IP address is primary control AC,
Also, primary control AC can be passed through different inside AC different by distributing different agent side slogans for each internal AC
Agent side slogan makes a distinction, and this mode can allow the quantity of the inside AC inside cloud AC infinitely to expand, no matter interior
Portion AC quantity increase is how much, as long as primary control AC is distinguished by different agent side slogan, management to internal AC nor
It is often convenient.
In addition, primary control AC, which can be not only AP, distributes internal AC, and the mutual message between AP and internal AC is forwarded, and
And the primary control AC can also be established with AP connect in itself.For example, when primary control AC is in step 201 AP points according to pre-defined rule
(for example, being distributed according to default corresponding relation, or distributed during with AC by hash algorithm), if obtained port numbers are main
AC itself incoming end slogan is controlled, then primary control AC can carry connecing for primary control AC itself in the discovery response message returned to AP
Inbound port number, the so AP can directly send the incoming end slogan of carrying primary control AC according to the incoming end slogan to primary control AC
Connection request message.Primary control AC is after the connection request message is received, it is not required that above-mentioned associated conversion operation is performed, with this
AP establishes connection.
After AP and cloud AC (internal AC or primary control AC) establishes connection, AP lower line process performs according to old process, no longer
It is described in detail.After AP is connected with cloud AC, AP can forward the message identifying and data message of user.Wherein, during the forwarding of data message,
The mode that high in the clouds certification can be used locally to forward, the i.e. data traffic of user can forward in AP.And the forwarding of message identifying
When, if certificate server and internal AC are located at same Intranet, internal AC and certificate server (for example, aaa server,
Portal server) interaction can directly use private network IP.
And when internal AC and certificate server be not in same Intranet, can be in the extra portion of Intranet where certificate server
A primary control AC is affixed one's name to, VPN (Virtual Private Network, VPN) is established between cloud AC primary control AC
Tunnel, by the vpn tunneling, forward the message identifying between the internal AC and certificate server.For example, see shown in Fig. 3,
The primary control AC 31 of Intranet deployment where certificate server, can be respectively with each certificate server (for example, aaa server 32
With Portal server 33) connect, the primary control AC 31 can establish vpn tunneling with the primary control AC 121 in cloud AC, pass through the VPN
Tunnel, internal AC can be interacted between certificate server.
