Embodiment 1
In order to solve in reality exploitation test environment, the true environment of a large amount of AP and STA can not be provided for cloud AC systems
Test, present embodiment discloses a kind of analogue simulation systems of AP and STA applied to cloud AC systems.
The analogue simulation system of the AP and STA applied to cloud AC systems of the present embodiment is based on TR-069 agreements, with reality
The analog simulation test of cloud AC systems is now accessed to high-volume AP.Wherein, TR-069 agreements full name is that " CPE wide area network management is assisted
View ", it provides the general framework and agreement that configuration is managed to home network device in next generation network, is used for from network
Side carries out remote centralized management to equipment such as gateway, router, set-top boxes in home network.
As depicted in figs. 1 and 2, the analogue simulation system 100 of the AP and STA of the present embodiment include a configuration management module
110 and at least one AP and STA analog modules 120.Wherein,
Configuration management module 110 inputs and parses the configuration file of AP and STA for selecting node deployment mode.
Node deployment mode is divided into single node deployment and distributed node deployment：
Single node is disposed as shown in Figure 1, the configuration management module 110 of the present embodiment and all AP and STA analog modules
120 are deployed on the same single node, can only provide 60000 AP virtual analog energy；
Distributed node is disposed as shown in Fig. 2, the configuration management module 110 of the present embodiment is deployed in configuration management node again
On, each AP and STA analog module 120 is deployed on different distributed nodes respectively again.It is disposed using distributed node,
Millions of virtual AP analog capabilities can be provided according to the expansion energy of node.
Configuration file is XML file, and configuration file includes but not limited to the AP quantity that need to be simulated, STA behavioral strategies, cloud
The port numbers of the IP address of AC systems and long Connection Service end.Wherein, AP quantity maximum can reach millions of.
Configuration management module 110 is additionally operable to parsing configuration file：
1) it according to the STA behavioral strategies in configuration file, simulates downtime in the dynamic of STA and uses flow, from
And calculate the accessible STA maximum quantities of an AP；
2) parsing configuration file generates MAC (Media Access Control) address sets and the mapping of node IP address is closed
System.In the case where distributed node is disposed, the maximum port number of operating system is 65535, and an AP occupies a port,
Quantity of 60000 idle port numbers as the virtual AP on a node, 60000 AP can be simulated by a node in terms of
The quantity of distributed node needed for calculating, further distributes the IP address of each distributed node.
Further, in the case where distributed node is disposed, before distributed node is accessed configuration management node, match
Setting management module 110 must judge whether the IP address of the distributed node where AP and STA analog modules 120 meets from configuration text
The IP address parsed in part：If met, allow its access；If do not met, do not allow to access.
AP and STA analog modules 120 according to node deployment mode and profile module with cloud AC systems 200 for communicating
The AP and STA of letter.
In the present embodiment, as depicted in figs. 1 and 2, AP and STA analog modules 120 include instance management submodule 121,
Connection management submodule 122, information receiving and transmitting submodule 123 and STA dynamic behaviours manage submodule 124.

AP data, AP business configurations data in analog module and STA flow amount data：
Instance management submodule 121 is according to the IP (Internet of node residing for AP and STA analog modules 120
Protocol) the mapping relations for the MAC Address collection and node IP address that address is parsed from configuration management module 110 obtain
Corresponding MAC Address collection, generates corresponding AP and STA examples.Wherein, AP and STA examples include but not limited to AP MAC Address,
The MAC Address (it is unique to generate MAC Address, will not be repeated) of STA, SSID (Service Set Identifier, services set
Mark), AP types, AP uplink and downlink flows, STA use flow, the STA quantity of access, the basic AP information such as black and white lists and
Business configuration data and STA data.
Further, instance management submodule 121, which also provides, can be read or change AP and the AP essential informations in STA examples
Interface give connection management submodule 122, information receiving and transmitting submodule 123 and STA dynamic behaviours management submodule 124 call.
Connection management submodule 122 is used for according to AP and STA examples, the IP address of cloud AC systems 200 and long connectivity port,
Establish the long interface channel with cloud AC systems 200：
Connection management submodule 122 triggers the long connection client of equal amount according to the AP quantity in configuration file, long
Port used in interface channel is port idle in 65535 operating system ports, and port point is carried out by sequence from small to large
Match.After the analogue simulation system of the present embodiment starts, cloud AC systems 200 are obtained in this module from configuration management module 110
IP address and long connectivity port, to establish and the long interface channels of cloud AC systems 200.
Information receiving and transmitting submodule 123 is used to receive the message that cloud AC systems 200 are sent according to long interface channel, and at simulation
Cloud AC systems 200 are returned message to after reason：
Information receiving and transmitting submodule 123 receives cloud AC systems 200 according to the long interface channel that connection management submodule is established
After message, analog service processing is carried out according to the type of message：If cloud AC systems 200 intentionally get the information of AP or business is matched
Data are set, information receiving and transmitting submodule 123 obtains this AP data from instance management submodule 121 and by corresponding long company
It connects road and is sent to cloud AC systems 200；If cloud AC systems 200 wish to change the business configuration data of AP, information receiving and transmitting submodule
Block 123 calls the corresponding interface in instance management submodule 121 to go modification AP business configuration data.In addition, information receiving and transmitting submodule
Block 123 can also actively send messages to cloud AC systems 200.
STA dynamic behaviours manage upper downtime and the use that submodule 124 is used to change according to configuration file dynamic STA
Flow, and it is uploaded to instance management submodule 121：
STA dynamic behaviours manage submodule 124 according to the behavioral strategy in the STA behavioral strategies in configuration file come dynamic
Simulation STA upper downtime and use flow.STA behavioral strategies can be divided into be commonly used, generally use and less use.
Defined according to the difference of STA behavioral strategies upper downtime frequency and using flow number.When STA reaches the standard grade, STA dynamics
This STA can be associated with corresponding AP by behavior management submodule 124 in real time, when STA is offline；STA dynamic behaviours manage submodule
124 can cancel and the association of corresponding AP in real time.STA reach the standard grade state when, STA dynamic behaviours manage submodule 124 also by mould
The data on flows drawn up is sent to instance management submodule 121 and is updated and preserves in real time.
In addition, in order to protrude the innovative part of the present invention, it will not be proposed by the invention with solution in the present embodiment
The less close unit of technical problem relationship introduces, but this does not indicate that there is no other units in the present embodiment.
