APAIMD Mechanism And APTCP Based On This Mechanism
Xuefeng Fan · Microcomputer applications · 2004
This paper proposes an AIMD mechanism whose parameters are adjustable, so called Adjustable Parameters AIMD or called APAIMD for short, and a transmission control protocol which realizes this mechanism at receivers and is fit for transporting multimedia traffic in Internet, as its parameters are adjustable, called Adjustable Parameters TCP or called APTCP for short. Neither UDP nor TCP can be used to transport multimedia data, because UDP has no congestion control mechanism and TCP reduces the sending rate in half in response to a single packet lost, which will result in rate wobbling greatly. Under the control of APTCP, multimedia traffic has good smoothness of sending rate and can share bandwidth with competing TCP flows fairly. APTCP has a promising avenue of development for multicast multimedia services, and can be used in unsymmetrical networks.
