“…The most widely deployed "broadband" solutions today are Digital Subscriber Line (DSL) and cable modem (CM) networks. Although they are an improvement compared to 56 Kbps dial-up lines, they are unable to provide enough bandwidth for emerging services such as Video-OnDemand (VoD) interactive gaming or two-way video conferencing [1]- [2]. A new technology is required one that is inexpensive, simple, scalable, and capable of delivering bundled voice, data and video services to an end-user over a single network.…”

Video MAC Protocol (VMP) in EPON based access networks. In triple-play (Data, Voice, and Video) service scenarios for such EPON based access networks, Optical network technologies are expected to converge in the near future, since the fiber networks hold great promise as future broadband communication. Video traffic will likely dominate in triple-play service scenarios for each fiber networks. It is proposed to introduce and analyze the Video MAC Protocol (VMP) to efficiently deliver pre-recorded video downstream to consumers over a fiber network in presence of voice and data upstream and downstream traffic. The VMP consists of three main components: (i) Frame Fragmentation and Hierarchical frame Aggregation, (ii) Multi-Polling Channel Access, and (iii) Prefetching for VBR Video Streams. By introducing VMP we are going to analyze the throughputdelay performance for all three traffic types: Voice Traffic, Video Traffic, and Data Traffic. In this paper we are evaluating a demand on request and performance evaluation of VMP. Video streaming according to the user requirement and encoded in three quality types of Video for low, medium and high quality users and the most common performance metrics are delay and throughput are compared with existing Mac protocol.

“…Techniques based on multi-and broadcast that periodically transmit segments of popular videos in optical access networks are studied in [31], [32]. In the recent studies [33], [34], these periodic transmission schemes are (i) extended with patching mechanisms that allow a receiver to quickly start video playback from a patch stream while storing the next video segments from the periodic transmissions, and (ii) refined with a range of performance enhancing mechanisms, such as downloading popular movies during night hours. These existing studies have in common that they do not consider the variable frame sizes of rate-distortion (RD)-efficient video codecs; instead, they approximate (or bound) the video bit rate as a constant bit rate.…”

Abstract-Optical and wireless network technologies are expected to converge in the near to midterm, giving rise to bimodal fiber-wireless (FiWi) broadband access networks. In triple-play (voice, video, and data) service scenarios for such FiWi access networks, video traffic will likely dominate due to the widely predicted increase in video network services and the high traffic volume of compressed video compared to voice and data services. In this paper, we introduce and evaluate a comprehensive video MAC protocol (VMP) to efficiently deliver prerecorded video downstream to wireless consumers over a FiWi network in the presence of voice and data upstream and downstream traffic. VMP consists of three main novel components: (i) frame fragmentation in conjunction with hierarchical frame aggregation for efficient MAC frame transport over the integrated optical and wireless network segments, (ii) multi-polling medium access control for upstream voice and data packets and acknowledgements for downstream video packets, and (iii) prefetching of video frames over the optical and wireless network segments in conjunction with hybrid reservation/contention-based medium access. Our simulation results indicate that VMP achieves significant improvements in throughput-delay performance for all three traffic types as well as reductions in the playback starvation probability for video traffic compared to existing state-of-the-art MAC mechanisms.Index Terms-EPON, FiWi, H.264 SVC, MAC layer protocol, prefetching, video streaming, wireless mesh network.

“…Nonetheless, 40Gbit/s DWDM deployment in LANs is not a panacea. There are a few difficulties, such as, multivendor interconnectivity, compatibility issues with the current layout, scattering resilience, and cost viability for widespread deployment [8,9]. The 40Gbit/s DWDM is going to be deployed firstly in core and long-haul networks, which makes it importantly required in optical networking transport [10,11].…”
