“…The direct live video can be divided into two sub-categories: live broadcast of TV such as BBC iPlayer 1 and private video communications such as Skype 2 . We have focused on the latter category as such applications typically are interactive in their nature and thus more sensitive to latency.…”

This paper assesses whether multi-path communication can help latency-sensitive applications to satisfy the requirements of their users. We consider Concurrent Multi-path Transfer for SCTP (CMT-SCTP) and Multi-path TCP (MPTCP) and evaluate their proficiency in transporting video, gaming, and web traffic over combinations of WLAN and 3G interfaces. To ensure the validity of our evaluation, several experimental approaches were used including simulation, emulation and live experiments. When paths are symmetric in terms of capacity, delay and loss rate, we find that the experienced latency is significantly reduced, compared to using a single path. Using multiple asymmetric paths does not affect latencyapplications do not experience any increase or decrease, but might benefit from other advantages of multipath communication. In the light of our conclusions, multi-path transport is suitable for latency-sensitive traffic and mature enough to be widely deployed.

“…For instance, freezing a live video just 1% of the video duration is sufficient to turn away 5% of the viewers [1]. Similarly, a latency of 60 ms suffices to degrade user experience in Internet gaming [2].…”

“…This destroys the flow of the video and its perception as a single unit/medium, decreasing the user's quality of experience. Concerning a single video, the findings of Hossfeld et al [27], Egger et al [15], and Krishnan and Sitaraman [31] show that stalling during video playback has a bad influence on the quality of experience while watching a video. According to their studies, initial delays and stallings have to be minimized to improve the QoE during playback; avoiding users' abandoning the video.…”

“…We take into account the abandonment 75 rate described in Krishnan and Sitaraman (2012), where the authors found that VoD clients start leaving the service after a start-up delay of 2000ms (milliseconds), losing 5.8% of users for each additional second. This delay time T D includes all network times, server times, and additional 80 overheads.…”
