Controlling smoothness and loss rate for elastic continuous media flows

چکیده
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.

Fast Learning Rate of Multiple Kernel Learning: Trade-Off between Sparsity and Smoothness
We investigate the learning rate of multiple kernel leaning (MKL) with l1 and elastic-net regularizations. The elastic-net regularization is a composition of an l1-regularizer for inducing the sparsity and an l2-regularizer for controlling the smoothness. We focus on a sparse setting where the total number of kernels is large but the number of non-zero components of the ground truth is relative...
متن کاملA Differentiated Pricing Framework for Improving the Performance of the Elastic Traffics in Data Networks
Rate allocation has become a demanding task in data networks as diversity in users and traffics proliferate. Most commonly used algorithm in end hosts is TCP. This is a loss based scheme therefore it exhibits oscillatory behavior which reduces network performance. Moreover, since the price for all sessions is based on the aggregate throughput, losses that are caused by TCP affect other sessions...
متن کاملExperiments in Best-Effort Multimedia Networking for a Distributed Virtual Environment
Until there is greater consensus on proposals for realizing better-than-best-effort services on the Internet, developers of multimedia and distributed virtual environment applications must rely on best-effort media adaptations to ameliorate the effects of network congestion. We present the results of a study on the use of adaptations originally developed for audio and video applications for the...

متن کاملA recursive formula for estimating the packet loss rate in IP networks
We present a recursive formula for estimating the packet loss rate in IP networks. Specifically, we consider a single link whose capacity is shared dynamically by elastic data flows, each characterized by some peak rate, and derive the formula from the steady-state distribution of the number and peak rates of ongoing flows. The result is particularly useful for dimensioning ISP backhaul network...
