MRF: A Framework for Source and Destination Based Bandwidth Differentiation Service

Price based joint source and channel coding for real time video applications over the Internet with flow rate management

“…However, this is not always true because different sources may have different willingness-to-pay [14]. It is thus necessary to generalize it by taking the willingness-to-pay into consideration so that different sources can get different bandwidths from the shared bottleneck link.…”

“…The algorithm for sending packets is then described below. Using standard techniques in gradient algorithm's convergence analysis and Propositions 1-3, it can be easily shown that Theorem 1: By the proposed algorithm that is composed of a source problem by (18), (14) and (15) and a congestion price updated rule at link l by (22), q l,s (k) converges to its optimal value q * l,s , and the correspondingX * and v * are the global optimal solution to the primal problem (11)-(15) if all γ l,s are very small and…”

Stability under events for a class of hybrid dynamical systems with continuous and discrete time variables

“…In recent years, it has seen significant development in the theory of hybrid dynamical systems (HDSs) due to its wide applications in areas such as control technology, communication networks, biological systems, and power systems, e.g. [1][2][3][4][5][6][7][8][9][10][11][12][13]. Generally, an HDS may exhibit different dynamical characteristics during different time intervals separated by events (switchings or impulses).…”

QoS-aware multicast for internet video applications

“…It adopts a twotimescale approach, which can optimize the video quality in short term (multimedia-friendliness) and meet the TCPfriendliness in long term. In [10] and [11], the bandwidth requirement of the multimedia application can be met by achieving proportional fairness with TCP, and multimedia-friendliness is regarded as TCP-friendliness with a weighting factor. The congestion control can adaptively adjust the weighting factor to get the necessary bandwidth and meet the QoS requirements of the multimedia application.…”
