Network Layer Coding for QUIC: Requirements

Internet Research Task Force - Working document of the Network Coding Research Group (NWCRG)This document presents the motivation and requirements for the use of Network Level Packet Erasure Coding to improve the performance of the QUIC protocol that is proposed a new transport protocol. The document does not specify a specific code but lists the salient features that a code should have in order to deal with know loss patterns on QUIC paths

Sliding Window Random Linear Code (RLC) Forward Erasure Correction (FEC) Schemes for QUIC

Internet Research Task Force, Coding for Efficient Network Communications Research Group (NWCRG) document, work in progress, https://datatracker.ietf.org/doc/draft-roca-nwcrg-rlc-fec-scheme-for-quic/This document specifies Sliding Window Random Linear Code (RLC) Forward Erasure Correction (FEC) Schemes for the QUIC transport protocol, in order to recover from packet losses

Coding for QUIC

Internet Research Task Force, Coding for Efficient Network Communications Research Group (NWCRG) document, work in progress, https://datatracker.ietf.org/doc/draft-swett-nwcrg-coding-for-quic/This document focusses on the integration of FEC coding in the QUIC transport protocol, in order to recover from packet losses. This document does not specify any FEC code but defines mechanisms to negotiate and integrate FEC Schemes in QUIC. By using proactive loss recovery, it is expected to improve QUIC performance in sessions impacted by packet losses. More precisely it is expected to improve QUIC performance with real-time sessions (since FEC coding makes packet loss recovery insensitive to the round trip time), with multicast sessions (since the same repair packet can recover several different losses at several receivers), and with multipath sessions (since repair packets add diversity)

Taxonomy of Coding Techniques for Efficient Network Communications

Internet Research Task Force, Request For Comments (RFC) 8406, https://datatracker.ietf.org/doc/rfc8406/This document summarizes recommended terminology for Network Coding concepts and constructs. It provides a comprehensive set of terms in order to avoid ambiguities in future IRTF and IETF documents on Network Coding. This document is the product of the Coding for Efficient Network Communications Research Group (NWCRG), and it is in line with the terminology used by the RFCs produced by the Reliable Multicast Transport (RMT) and FEC Framework (FECFRAME) IETF working groups

IPTV: Now and Next

This keynote address wants to establish the current status of IPTV and define how it will evolve with the new ubiquity of Internet video and smartphones with Web access. In particular, the discussion centers on how IPTV will move across device boundaries and include features now associated with over the top offerings and social networks

Video-centric network coding strategies for 4G wireless networks: an overview

The impact of Internet content and IP based television on networks is growing. Video is now ubiquitous in the home and on the street. It demands new approaches to video transmission to meet the growing traffic volume. This paper presents a novel strategy for network coding in video transmission. It uses a variety of coding approaches and adds feedback and device discovery to tailor the coding to the receiver ecosystems and can achieve better overall performance than the non coded versions.University of California, Santa Cruz (Subcontract #S0176938)United States.

neXtream: a multi-device, social approach to video content consumption

Video content has become available on an increasingly diverse set of devices and from an ever growing number of sources, creating a vast amount of choice for viewers. At the same time, the varying methods of viewing, interacting with, and sharing content have diverged. This paper introduces neXtream, a new approach to delivering video by integrating multiple devices, content sources, and social networks. This concept is developed following research in social television and converged applications, providing both personalization features and social interaction. NeXtream delivers video by dynamically generating streams of video customized to a viewer, while facilitating a common dialog between users around the content, creating both a user- and community-centric viewing experience. NeXtream integrates smartphones, PCs, and TVs to deliver video content to viewers. The paper presents the system concept, theory, and architecture, and describes the developed prototype

Building Social Services

Abstract-Making a service social means providing a way for users to engage with a product or service as a group. We are specifically interested in groups based on connections that are established using the emerging online social networking tools like Facebook, MySpace, etc. This paper explores the value chain dynamics resulting from the integration of social networks with a given service. The example we will be using in this paper involves social TV applications, with a focus on social discovery. We hypothesize that these mashup social services introduce new control points in a given service's value chain, which complement or compete with existing control points. The paper focuses on the North American experience
