In this paper we present a congestion response mechanism designed for time-sensitive traffic based on the principle of direct protocol interactivity. We envision a transport mechanism, which is interactive and can provide event notification to the subscriber of its communication service. We then show a friendly adaptive MPEG-2 video transcoding scheme, which directly interacts with the transpor...

This memo describes the use of a Remote Authentication Dial-In User Service (RADIUS) authentication and authorization service with Simple Network Management Protocol (SNMP) secure Transport Models to authenticate users and authorize creation of secure transport sessions. While the recommendations of this memo are generally applicable to a broad class of SNMP Transport Models, the examples focus...

SCTP (Stream Control Transmission Protocol) is a new IETF transport protocol over the IP network. Transport protocol is responsible for reliable delivery of a message form a host to another host. We proposed and implemented an efficient file transfer system using the SCTP multiple file transfer and modified STCP congestion control mechanism to guarantees a stable data transfer with multi-stream...

In this paper, we outline an architecture which enables the real-time delivery of continuous media over the Internet using the Real-time Transport Protocol (RTP). We present our implementation of RTP with its control protocol RTCP. RTCP feedback reports are used by our adaptive rate controller to help reduce congestion. Then, we assess the functionality of RTP and its suitability for the future...

In this paper, we propose RALF, a new FEC-based error control protocol for layered multicast video. RALF embodies two design principles: decoupling transport layer error control from upper layer mechanisms and decoupling error control and congestion control at the transport layer. RALF works with our previously proposed protocol RALM — a layered multicast congestion control protocol with router...
