Method and device for controlling packet sending rate of user

Abstract

The invention discloses a method and a device for controlling packet sending rate of a user, which relates to the technical field of communication and is invented to ensure the lowest packet sending rate of the user. The method comprises the following steps: user access is controlled according to the user access strategy, and a packet is scheduled according to the packet scheduling strategy; when a new user requests accessing, whether the average packet sending rate of the users of the whole network is smaller than or equal to a preset rate threshold value is judged; if so, the accessing of the new user is rejected; if not, the new user is accessed; when the packet is received, the former packet sending rate of the user owing the packet is obtained; and when the former packet sending rate of the user owing the packet is smaller than or equal to the preset rate threshold value, the packet is a first packet, and the first packet is added in a queue. The method and the device are mainly applied to the wireless local area network technology.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a device for controlling a user's packet sending rate. Background technique [0002] Wireless Local Area Networks (WLAN for short) is a very convenient data transmission system at present. It uses radio frequency technology (Radio Frequency, RF for short) to replace the traditional wired local area network composed of twisted The access structure realizes the communication. [0003] Since the birth of WLAN technology, because of its advantages of convenience and low cost, WLAN technology has been favored by the majority of users, and its technical standards have also been developed rapidly. In recent years, in order to meet the continuous demand of users for high transmission rate, the Institute of Electrical and Electronics Engineers (IEEE for short) group successively launched IEEE802.11, IEEE802.11b and IEEE802.11a, the data of WLAN technology The transmi...

Problems solved by technology

Although this queuing rule can give priority to the transmission of important data packets, for users with low network card performance, especially when the user transmits data packets with a low priority, the sending rate of the user's data packets cannot be guaranteed.

Although the existing technology allocates the bandwidth of the entire network by limiting the speed of users with high network card performance and mapping user queues, it can limit the excessive bandwidth occupied by users with high network card performance, but it cannot guarantee the packet sending rate of users with low network card performance.
