Controlling smoothness and loss rate for elastic continuous media flows
The class of rate adaptation schemes based on linear loss dependent decrease (LDD) policies is considered. A particular LDD policy, referred to as the history independent (hi)-LDD policy, is identified and studied here and some interesting properties are shown. Based on these properties it is possible to estimate the fair share and use it to adjust dynamically the control parameters so that a given targeted level of smoothness and loss rate be achieved; this policy is referred to as the Dynamic hi-LDD policy. Rate adaptation schemes based on the introduced Dynamic hi-LDD policy are suitable for elastic continuous media (CM) flows since they provide for a smooth rate adaptation and low packet loss rates. Numerical results illustrate the good properties and intrinsic advantages of the investigated schemes.
