SRAMT-LE: A Hybrid Sender and Receiver-Based Adaptation Scheme for TCP Friendly Multicast Transmission Using Layered Encoding
- …In this paper we describe a hybrid sender and receiver-based adaptation scheme for multicast transmission of multimedia data using layered encoding, which we call SRAMT-LE (Sender-Receiver based Adaptation scheme for Multicast Transmission using Layered Encoding). The most prominent features of SRAM…

Corresponding author:
- …Internet is a heterogeneous network environment and the network resources that are available to multimedia applications can be modified very quickly. Multimedia applications must have the capability to adapt their operation to network changes. In order to add adaptation characteristics to multimedia…

ODL Services and PTTs: The Greek PTT Case
- …During the last years Open and Distance Learning (ODL) methods that utilise network resources and services are gaining wide acceptance. An increasingly number of enterprises uses ODL for training their employees. Interestingly enough not all the enterprises that want to and can use ODL are doing so.…

IV.2 Smooth Multicast Congestion Control for Adaptive Multimedia Transmission
- …Abstract — In this paper we introduce an equation-based smooth multicast congestion control for adaptive multimedia transmission over best-effort wired networks. Target of the proposed schema is (a) smooth transmission rate, in order to minimize the Audio-Video (AV) encoding and decoding distortion …

#20 Adaptive Smooth Multicast Protocol for Multimedia Data Transmission
- …(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 estimation of protocol parameters and dynamic adjustment of the “smoothness factor”. ASMP key attributes are: a) adaptive scalabili…

Comparison of Single-Rate Multicast Congestion Control Protocols vs. ASMP
- …Abstract * We present in this paper a simulation-based comparison of two single-rate multicast congestion control schemes (TFMCC and PGMCC) against our proposed Adaptive Smooth Multicast Protocol (ASMP). ASMP consists of a single-rate multicast congestion control, which takes advantage of RTCP Sende…
