Joint IST Symposium on Mobile Future, and the Symposium on Trends in Communications, SympoTIC
作者: A. Chodorek R.R. Chodorek Department of Telecommunications and Photonics Kielce University of Technology Kielce Poland Department of Telecommunications AGH University of Science and Technology Krakow Poland
In multipurpose, multiservice network, real-time data (e.g. video over RTP) are transmitted in the same link with bulk data (e.g. ftp over TCP). Although real-time transmission usually doesn't occupy the whole lin... 详细信息
