Abstract
Abstract A packet transmission method and apparatus, according to which short data samples or mini packets from several simultaneous connections are multiplexed to a variable length packet. The length of the mini packets is defined in a common length field for mini packets of the same length, which saves bandwidth. Each mini packet has its own header, which defines at least an identification information of the mini packet. Thus, the variable length packet, e.g. an IP packet, includes a plurality of mini packets with a minimum header portion, such that transmission overhead is reduced due to the fact that most mini packets tend to be of the same length. Moreover, different queues for mini packets of one respective length may be provided, from which mini packets of one length are multiplexed to the variable length data packet. Thereby, the ratio of variable length data packets including mini packets of one length is further increased so as to further decrease the transmission overhead.
