...e, etc. Recent research in support for multimedia communication tends to refute the commonly held belief that unreliable transport is the best choice for network multimedia applications. For example, =-=[16]-=- strongly argues for streaming over the reliable connection-oriented TCP as a viable alternative to connectionless, 8 struct { char fname[1024]; // file name int off; // file offset } state_snap while...

...d thus re-sending media data may not be appropriate because it would arrive too late for display at the receiver. Recently, several approaches have been proposed to overcome these problems [4], [26], =-=[14]-=-, [25], [18]. These TCPbased stored media streaming approaches use a combination of client-side buffering and efficient QoS adaptation of the streamed data. Client-side buffering essentially borrows s...

... the possibility of efficient video streaming over TCP. There have been several recent proposals which challenge the long-held belief that TCP is unsuitable for streaming applications. The authors of =-=[15]-=- provide a qualitative argument for the possibility of multimedia streaming using TCP. They note that client-side buffering can handle both the retransmission delays, and congestion control induced th...

... for multimedia streaming applications. Recent studies reveal that the instantaneous transmission rate variation of TCP called short-term throughput can be smoothed out by receiver-side buffering. In =-=[5]-=-, the authors propose that the receiver side buffer can be used to smooth out the variation effect of TCP transmission rate. Furthermore, paper [4] discusses the receiver buffer requirement and presen...

...smissions and inorder delivery. As a result, it was widely accepted that TCP is not adequate for multimedia streaming, which is delay sensitive but to some extent loss tolerant. Later, the authors of =-=[2]-=- reported that the instantaneous transmission rate and transmission delay variation of TCP can be smoothed out by receiver-side buffering. Moreover, a dominant share of multimedia traffic is being del...

...raints, such as streaming. TCP can be used for multimedia streaming by for example RealAudio[9] and Microsoft Windows Media Player[10]. The case for multimedia streaming with TCP is further argued in =-=[11]-=-, [12]. To determine what gains can be made by accepting bit errors, an initial implementation of the idea has been performed in the Linux kernel. This modification is called “TCP-L”, as an indication...

...y but this work also lacks the TCP-friendliness component. A number of studies focus on streaming video using new TCP-friendly transport protocols [18],[7] while others employing TCP itself [28],[29],=-=[30]-=-,[31]. One common objection to use of TCP for streaming applications is the fully reliable service model of TCP through retransmissions [30]. While delays due to retransmissions may not be tolerable f...

We have used it for visualizing and debugging various time-sensitive applications, including a CPU scheduler [19], a quality-adaptive streaming media player =-=[14]-=-, a network traffic generator called mxtraf [13], and various control algorithms such as a software implementation of a phase-lock loop [9]. We believe that applications using gscope will see a direct...
