Description
Technical field
The exemplary embodiment of the present invention relates to method of testing and the system that a kind of simulation wireless stations (STA) is reached the standard grade, specifically, relate to a kind of by amendment STACAPWAP data message produce a large amount of STA simulation CAPWAP data message simulate method of testing and the system that wireless STA reaches the standard grade.
Background technology
WAP (AP) also referred to as wireless bridge, radio network gateway, the most so-called " thin " AP.The transmission mechanism of this wireless device is equivalent to the hub in cable network, the most ceaselessly receives and transmits data.Any personal computer equipped with wireless network card (PC) all can share the wired local area network even resource of Wide Area Network by AP.In theory, when network increases after a wireless aps, can extended network covering diameter exponentially, also can make network accommodates the more network equipment.Each wireless aps is substantially all and has an Ethernet interface, for realizing wireless Yu wired connection.
Wireless controller (AC) is a kind of network equipment, and it is the core of a wireless network, and the thin AP(being responsible in wireless network only carries out receiving and transmitting signal), AP management is included: issue configuration, amendment relevant configured parameter, radio-frequency intelligent management etc..WIFI network of today covers, the coverage modes using AC+AP more, i.e., wireless network exists an AC and multiple AP(receiving and transmitting signal), this model application in large and medium-sized enterprise, the beneficially centralized management of wireless network, multiple wireless transmitters can unify launch a signal (SSID, service set), and support seamless roam and the intelligent management of AP radio frequency.Compared to traditional covering pattern, there is the lifting of essence.
STA refers to be equipped with the calculating equipment of radio network interface.One wireless STA is generally added lastblock wireless network card by a PC or notebook and constitutes, wireless network card is divided into the PCI(Peripheral Component Interconnect standard of desktop computer) or ISA(industrial standard architectures) network interface card of slot and the PCMCIA(PCMCIA (personal computer memory card international association) of notebook computer) network interface card, wireless terminal can also is that the embedded device (such as 802.11 mobile phone) being provided that wireless connections in non-computer terminal in addition.
CAPWAP (ControlandProvisioningofWirelessAccessPoints, the control of WAP and supply agreement) is a kind of general tunnel protocol, completes AP and finds the basic agreement functions such as AC, is divided into control passage and data channel.Control passage (a two-way data stream) by IP, WTP(wireless transmission protocol of AC) IP, AC control port, the control port of WTP and transport layer protocol (UDP or UDP-Lite) this five-tuple determine, be responsible for transmitting-receiving CAPWAP and control message.Data channel is also made up of five-tuple, is responsible for transmitting-receiving CAPWAP data message.
