“…Jitter in a streaming system [29] is avoided by having a delay jitter buffer at the receiver placed before the video decoding buffer that compensates for channel and traffic arrival variations. However, [30] showed that a single receiver buffer is sufficient to achieve a certain QoS guarantee. It can be seen from our experiments that the jitter after using variable bucket size network coding improves by 70% when compared with only TCP and by 60% when compared with TCP and fixed size network coding.…”

Network coding (NC) techniques for lossy wireless networks have been used for fault-tolerant and timely delivery of streaming video data. Recent research on inter-session NC notwithstanding, reliable transmission of high quality media over wireless networks continues to be a challenge. The effects of traffic and network dynamics on coding block size and thereby on latency added at playback were studied, and the interaction of congestion control on the coding technique to remedy this were examined. Simulations show an inherent latency in video playback when TCP with random linear NC is employed as the receiver needs to wait for a certain number of packets to arrive before they are decoded. This paper presents an adaptive NC algorithm based on the nature of video streaming traffic and the available transmission opportunity to improve streaming performance with lower latency and reduced jitter in case of streaming TCP traffic. This algorithm is constructed under the constraint of available transmission opportunities and arriving traffic. The simulation results corroborate that the proposed adaptive NC algorithm reduces observed latency at playback by more than 90% over traditional TCP and more than 60% over simple NC technique. Additionally, the observed jitter reduced by 70% over only TCP and about 60% over fixed bucket size NC. To demonstrate the utility of our approach, the proposed algorithm was compared with TCP's performance for a real-world video trace. Results from this experiment indicated an 80% reduction in end-to-end latency.

“…By this the problems related to buffer adoption and delay bounds with data rate have been extracted. Admission Control for Statistical QoS proposed by Shroff et al [16] in which a buffer-less multiplexer introduces and they conclude economics of scale in the number of multiplexed flows was a crucial component in achieving a high degree of accuracy. They also experimentally observed loss curves (loss probability vs. buffer size).…”

ABSTRACT:The FIFO buffer used in high speed data links plays an important role in data transfer and depending upon the application the size of FIFO is variable in nature which known as buffer adoption. There are different buffer adoption schemes for FIFO buffer, some of which are based on goodput, throughput, speed, network natures etc. This paper presents the study of those current various FIFO buffer adoption schemes which employs in current best effort data networks. Also the some proposed works are hereby studied and the conclusion have made by this study. This study work have done in three phase. Firstly the different types of FIFO architecture have studied and present the basic architecture of it. Second the problem identification has been done by literature review of different network architecture proposed. Finally the few best FIFO buffer adoption techniques are studied followed by literature review as extension of it. The RADA scheme is concluded the best buffer adoption scheme among all the papers studied during study.

“…The equation (15) means that the probability of no starvation is 1 conditioned by i ≥ 1 and n = 1. Thus, the probability of having one or more starvations is 0 obviously if the only packet sees a nonempty system.…”

Abstract-Our purpose in this paper is to obtain the exact distribution of the number of buffer starvations within a sequence of N consecutive packet arrivals. The buffer is modeled as an M/M/1 queue.When the buffer is empty, the service restarts after a certain amount of packets are prefetched. With this goal, we propose two approaches, one of which is based on Ballot theorem, and the other uses recursive equations. The Ballot theorem approach gives an explicit solution, but at the cost of the high complexity order in certain circumstances. The recursive approach, though not offering an explicit result, needs fewer computations. We further propose a fluid analysis of starvation probability on the file level, given the distribution of file size and the traffic intensity. The starvation probabilities of this paper have many potential applications. We apply them to optimize the quality of experience (QoE) of media streaming service, by exploiting the tradeoff between the start-up delay and the starvation.
