Existing researches on performance analysis of SCTP’s Concurrent Multipath Transfer (CMT-SCTP) usually use DropTail algorithm as queue management algorithm without considering the impact of the background traffic. However, the background traffic of realistic network environments has an important impact on the QoS of SCTP. Besides, more and more Active Queue Management (AQM) algorithms have been...
Communication protocols issues are one of the effective factors in communicated networks performance. One of challenging problem in CMT-SCTP which sends data by multipath concurrently is Receive Buffer Blocking. This problem has important role in data transmission speed in computer networks. In this paper, we propose a control method based on fuzzy logic so that can solve Receive Buffer Blockin...
The growing availability of multiple network interfaces on both mobile and fixed hosts makes concurrent multipath transfer (CMT) an appealing option to improve the performance of increasingly bandwidth-hungry multimedia applications. The Westwood Stream Control Transmission Protocol with Partial Reliability (W-PR-SCTP) is a partially reliable, SCTP-based transport protocol featuring a novel ada...
TCP and UDP are the most popular transport protocols used for end-end data transmission. The rapid growth of internet leads to development of many innovative applications in the current environment. Depending on the functionality of these applications, requirements of transport protocols are changing. TCP is known for its problems with Head Of Line blocking (HOL) and SYN attacks which gives red...
SCTP is a general-purpose Transport Layer protocol with out-of-the-box support for multi-streaming as well as multihoming. A protocol extension, which is denoted as CMTSCTP, extends SCTP by supporting Concurrent Multipath Transfer (CMT). That is, multiple network paths are utilized simultaneously in order to improve the payload data throughput. However, dissimilar paths – i.e. paths having diff...
Abstract Stream Control Transmission Protocol (SCTP) exploits multiple network interfaces to provide multi-streaming and data chunk ordering in a stream. An extended feature of SCTP, i.e., Concurrent Multi-path Transfer (CMT), bids concurrent transmission multi-path transfer environment guarantees bandwidth aggregation, load sharing, robustness, reliability. In such an environment, the paths us...
Preliminary work introduced Non-Renegable Selective Acknowledgments (NR-SACKs) and showed they (i) better utilize a data sender’s memory in both SCTP and CMT, and (ii) improve throughput in CMT. In this paper, we provide the latest specification of NR-SACKs, and extend the investigation of throughput improvements that NR-SACKs can provide. Using ns-2 simulation, for various loss conditions and ...
In recent years, the growing interest in the Intelligent Transportation Systems (ITS) has resulted in variety of peerreviewed publications. Significant results in this area have enabled many civilian and industry applications. As more and more vehicles are equipped with multiple network interfaces, how to efficient utilize the coexistence of Radio Access Technologies (RAT) such as WiFi, UMTS an...
Previously, we identified the failure-induced receive buffer (rbuf) blocking problem in Concurrent Multipath Transfer using SCTP multihoming (CMT), and proposed CMT with a Potentially-failed destination state (CMT-PF) to alleviate rbuf blocking. In this paper we complete our evaluation of CMT vs. CMT-PF. Using NS-2 simulations we first show that CMT-PF performs on par or better than CMT during ...
