PACKET TRANSMISSION METHOD AND DEVICE

摘要

The present invention relates to the field of communications. Disclosed are a packet transmission method and device, capable of reducing the number of calculations of required tokens during the packet transmission process. The method comprises: receiving a packet, and calculating according to the packet length the number of tokens TL used for transmitting the packet (101); acquiring the number of currently available tokens Tadd in a token bucket (102); if the number of the currently available tokens Tadd is smaller than the number of tokens TL used for transmitting the packet, then calculating the delay time Tdelay and starting to keep the time, the delay time being Tdelay = (TL-Tadd)/V, wherein V represents the token filling rate (103); and transmitting the packet when the delay time expires (104). The present invention is applicable to network packet transmission.
