Performance analysis and improvement of PR-SCTP for small messages
نویسندگان
چکیده
PR-SCTP, a partially reliable extension of SCTP, provides a flexible QoS tradeoff between timeliness and reliability for application traffic. However, the performance of PR-SCTP can be affected by certain traffic characteristics and network scenarios. We previously proposed an NR-SACK based optimization for PR-SCTP. In this work we extensively evaluate and analyze the performance of PR-SCTP with NR-SACKs using different network scenarios. Moreover, we compare the performance of our NR-SACK based PR-SCTP with existing transport protocols for syslog traffic. In the evaluation, we use real syslog traces from an operational syslog system. The results indicate that NR-SACK based PRSCTP significantly improves the overall message transfer delay as compared to SCTP and TCP.

Priority Based Delivery of PR-SCTP Messages in a Syslog Context
Unquestionably, syslog provides the most popular and easily manageable computer system logging environment. In a computer network, syslog messages are used for several purposes such as for optimizing system performance, logging user’s actions and investigating malicious activities. Due to all these essential utilities, a competent transport service for syslog messages becomes important. Most of...
متن کاملPerformance Evaluations for Multimedia Applications over Pr - Sctp
As multimedia applications over the Internet proliferate, the efficient transport of both the signaling and multimedia data becomes increasingly important. Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), the two most widely used but limited transport protocols, are not well suited to contemporary multimedia applications involving digital voice, audio and video communicatio...
متن کاملImproving Multimedia Performance over Lossy Networks via Sctp
The Stream Control Transmission Protocol (SCTP) is a new Internet standards track transport layer protocol. SCTP was designed to transport PSTN signaling messages over IP networks, but SCTP is also capable of serving as a generalized transport protocol. As such, SCTP provides an alternative to the traditional transport protocols, TCP and UDP, that may be better able to satisfy the requirements ...

Video streaming hot-plug is defined as keeping video streaming to be continuous when a host is switched from wired/wireless to wireless/wired networks, or from one wireless network to another wireless network. In this paper, video streaming hot-plug mechanisms using Stream Control Transmission Protocol (SCTP), which is a new transport layer protocol supporting multihoming, are investigated. Usi...
