This document is an Internet-Draft. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropr...

Hierarchical feedback aggregation is an enhancement to the RTP/RTCP (Real Time Protocol/Real Time Control Protocol) when the SSM (Source-Specific Multicast) is employed. The main purpose of feedback transmission is to provide information about media delivery and information needed for RTP/RTCP session management. This paper deals with a tree structure for hierarchical feedback aggregation speci...

Newer social multimedia applications, such as Social TV or networked multi-player games, enable independent groups (or clusters) of users to interact among themselvesand share services within the context of simultaneous media content consumption. In such scenarios, concurrently synchronized playout points must be ensured so as not to degrade the user experience on such interaction. We refer to ...

In this paper we propose a new single-rate multicast congestion control scheme named Adaptive Smooth Multicast Protocol (ASMP), for multimedia transmission over best-effort networks. The smoothness lays in the calculation and adaptation of the transmission rate, which is based on dynamic estimations of protocols’ parameters and dynamic adjustment of the ‘smoothness factor’, as well. ASMP key at...

This document defines a Session Initiation Protocol (SIP) event package that enables the collection and reporting of metrics that measure the quality for Voice over Internet Protocol (VoIP) sessions. Voice call quality information derived from RTP Control Protocol Extended Reports (RTCP-XR) and call information from SIP is conveyed from a User Agent (UA) in a session, known as a reporter, to a ...

We introduce an internet protocol version 6 (IPv6) audio conferencing tool implemented using MPEG-1 layer 3 (MP3) codec. In this paper, we present the software architecture, hurdles and tactics while developing the application based on existing modules like public MP3 encoder/decoder and real-time transport protocol (RTP)/ real-time transport control protocol (RTCP) implementation. And some exp...

Currently, several media sharing applications that allow social interactions between distributed users are gaining momentum. In these networked scenarios, synchronized playout between the involved participants must be provided to enable truly interactive and coherent shared media experiences. This research topic is known as Inter-Destination Media Synchronization (IDMS). This paper presents the...

Farmers in Assam's North Bank Plains Zone are generally resource-poor and have limited adaptation ability; rainfall anomalies make the Zone's rainfed agriculture very sensitive, risky, unprofitable. Participatory on-farm trials involving 25 farmers (5 from each village) representing different land situations for evaluating various adaptive strategies on rice-based cropping systems were conducte...

The “EOIP; Every Thing Over IP“ networks are widely replacing today’s different pillar networks in to the single converged network for Telephony(Any type of Access i.e. Mobile or Fixed Line) and data. Definitely new services will be expected in the NGN / EOIP such as broadcast media transmission and video on demand. But one major issues are always from past so many years are associated with Int...

Internet Drafts are draft documents valid for a maximum of six months. Internet Drafts may be updated, replaced, or obsoleted by other documents at any time. It is not appropriate to use Internet Drafts as reference material or to cite them other than as a ''working draft'' or ''work in progress.''
