A Practical Semantic Reliable Multicast Architecture
نویسندگان
چکیده
IP Multicast has been developed in the past few years to support multi-point communication in Internet. However, it is still hard for protocol designers to tackle the intrinsic heterogeneity of networks and end-systems. Moreover, in practical, current Internet is not fully multicast-enabled. In this paper, we present a practical semantic reliable multicast (PSRM) architecture for current Internet-based applications. It takes the notion of “semantic” reliability and leverages application-specific semantics to transcode content during delivery. By combining multicast and unicast, PSRM becomes much more practical in the current Internet infrastructure, and benefits from IP multicast to maximum extent.

A Pragmatic Semantic Reliable Multicast Architecture for Distant Learning
Although IP multicast has been rapidly evolving in the last few years, the current Internet is not fully multicast-enabled because of the lack of robust inter-domain routing and controlling protocols. In this paper, we present an alternative architecture for data distribution on Internet called PSRM that realizes semantic reliable, loose synchronized, multicast data delivery. PSRM is not based ...
متن کاملProbabilistic Semantically Reliable Multicast ( Extended
Traditional reliable broadcast protocols fail to scale to large settings [13, 1]. This paper proposes a reliable multicast protocol that integrates two recent approaches to deal with the large-scale dimension in group communication protocols: gossip-based probabilistic broadcast [2] and semantic reliability [10]. The aim of the resulting protocol is to improve the resiliency of the probabilisti...
متن کاملA Loss Detection Service for Active Reliable Multicast Protocols
Reliable multicast protocols have gained popularity with active service contributions where routers implement additional functionalities. Reducing the delay of recovery is one of the desirable features of a reliable multicast protocol. In this paper we propose an active-based architecture with specialized routers. Using simulations we show how this architecture with the proposed services (mainl...
متن کاملReliable Multicasting in the Internet: Experience with the IRMA Architecture
In this paper, we present our experience with the IRMA reliable multicast architecture. IRMA guarantees reliable, sequenced, and loosely synchronized delivery of multicast streams by supporting TCP as the multicast transport protocol at the end hosts without modifications to the standard TCP/IP stack. To support TCP as the multicast transport protocol, IRMA provides ACK aggregation, local recov...
متن کاملIRMA: A Reliable Multicast Architecture for the Internet
IRMA is a reliable multicast architecture that guarantees reliable, sequenced, and loosely synchronized delivery of multicast streams. IRMA provides ACK-based reliability, hybrid local server-initiated and sender-initiated loss recovery, and support for end-to-end flow control and congestion control. Unlike most contemporary work, IRMA supports TCP as the reliable multicast transport protocol a...
