Embodiment

[0027] Example: such as figure 2 As shown, a method for measuring transmission performance between a wireless access controller AC and a wireless access point AP in this embodiment includes the following steps:

[0028] First, the wireless access point (hereinafter referred to as AP) and the wireless access controller (hereinafter referred to as AC) establish a connection relationship through a CAPWAP tunnel. After the connection is successfully established, the AC constructs a transmission performance measurement packet and periodically sends transmission performance to the AP. Measurement package. The AC sends transmission performance measurement packets to all APs in the system through the CAPWAP tunnel, and records the sending time of each measurement packet. The transmission performance measurement packet sent by the AC includes information on the number of sent packets and the number of bytes sent in the CAPWAP tunnel within a measurement period, where a measurement pe...

Abstract

The invention discloses a measurement method of transmission performance between a wireless access controller AC and a wireless access point AP, wherein connection is established between the AC and the AP by a CAPWAP tunnel; after connection is accomplished, the AC transmits performance measurement packages to the AP periodically; after receiving one measurement package, the AP feeds back a measurement response package; and the AC calculates parameters of transmission performance between the wireless access controller AC and the wireless access point AP according to information in the measurement response package. The measurement method can effectively detect condition of end-to-end transmission performance and obviously improve the measurement efficiency of links between the AP and the AC, thus leading intelligent dynamic regulation on the wireless access point to be realized in later period and the maximum guaranteeing of service quality of a user to be possible.

Description

technical field [0001] The present invention relates to a link between a wireless access controller (AC, Access Controller) and a wireless access point (AP, Access Point) in a wireless local area network (WLAN, Wireless Local Area Network), in particular to a wireless access control A method for measuring the transmission performance between the AC and the wireless access point AP. Background technique [0002] Wireless local area network WLAN provides a wireless connection service of local area network. The wireless access point AP is a wireless transceiver device in the wireless local area network, which is used to convert the data received from the wired network, such as the Internet Intenet, into a wireless signal for transmission, and to receive The incoming wireless signal is converted into data and forwarded to the wired network. [0003] In response to the needs of enterprise users, the Internet Engineering Task Force (IETF, Internet Engineering Task Force) establis...
