“…Real-time media flow protocol: Real Time Media Flow Protocol (RTMFP) [16], [18] makes use of UDP hole punching technique identical to the STUN protocol. Supporting only UDP-based direct connections, this protocol focuses on principles such as low delay time, data prioritization and P2P data distribution without a media distributor server.…”

SUMMARYThe usage of peer-to-peer (P2P) networks that provide sharing of real-time environmental data by internet users is becoming more and more popular. As a result, it's necessary to identify the problems during P2P communication and to develop proper solutions. One of the major problems of P2P communication is that it's not possible to reach the clients behind devices that create private networks like network address translation (NAT) and firewalls from the public network. Among the solutions proposed for this problem, Interactive Connectivity Establishment (ICE) and Real Time Media Flow Protocol (RTMFP) are the methods most preferred in the literature. These methods seem more attractive than other NAT traversal mechanisms since they are independent from internet infrastructure and are also appropriate for dynamic structures. However, they do have some disadvantages. In this study, a new state-based end-to-end communication technique (SBN) for NAT traversal was designed and realized. The performance of the designed method was evaluated against three criteria, connectivity check delay, connection packet count and bandwidth, and compared with the ICE method. The results revealed that the suggested SBN method proved an average of 78% success in connectivity check delay, 69% in the number of packets used and 66% in the consumption of bandwidth over the ICE method.

“…The video quality is analysed by varying the frames per second and frame resolution using the HTTP protocol and a multiple threads decoder. A multicast streaming application using real-time media flow protocol (RTMFP) protocol was also reported in Xue et al (2012). The main aim in this study was to identify the features of RTMFP protocol such as low latency and data prioritisation.…”

Abstract:Multimedia transmission over lossy networks has been rapidly increasing, especially with the advent of different high-speed and cost-effective Internet technologies. Despite these technology advances, however, the quality of video streaming over lossy networks is still a major challenge towards obtaining the best quality of service. In this paper, a new experimental testbed that is based on the real-time media flow protocol (RTMFP) is proposed to enable researchers to investigate and optimise the effect of changing multiple key parameters relevant to the video-streaming quality. The impact of these parameters, which include video resolution, frames per second, and compression rate on the video quality are investigated with various settings of network packet loss. The obtained results and relationships between these parameters have led to development of a new algorithm that is capable of changing the parameters under study, in real time, according to the estimated packet loss towards maximum obtainable quality. Design details and experimental setup of the proposed testbed are presented along with key practical considerations and experimental evaluation results.
