Item QUIC Protocol Performance in Wireless Networks(Institute of Electrical and Electronics Engineers Inc., 2018) Kharat, P.; Rege, A.; Goel, A.; Kulkarni, M.Google's Quick UDP Internet Connections QUIC transport layer protocol was developed in 2013 as a successor to its own SPDY networking protocol, which itself led to the formation of the HTTP/2 standard. QUIC's main motives were to take the advantages of TCP/IP and HTTP/2, and build them over UDP, in terms of reliability, flow control, and congestion control. The primary objective of this paper is to explore QUIC functionalities to suggest techniques to improve throughput, speedup and efficiency in wireless networks. The experimental results were established on a local test bed setup connected to a wireless access point in a campus network environment. Experimental results show that QUIC performance in the form of throughput and speedup over TCP/IP in live network environment. The fairness of QUIC in competing flow situations is also examined, and found to perform well in long life traffic. We also propose the reintroduction of FEC for minimization of retransmission latencies. © 2018 IEEE.Item Congestion controlling schemes for high-speed data networks: A survey(IOS Press Nieuwe Hemweg 6B Amsterdam 1013 BG, 2019) Kharat, P.; Kulkarni, M.The data networks are basically designed with the aim of maximum throughput and fair resource allocation by managing available resources. A transport layer plays an important role in throughput and fairness with the help of congestion control algorithms (variants). This survey targets mainly congestion issues in high-speed data networks to improve efficiency at connection or flow level. Transmission Control Protocol (TCP) is a dominating transport layer protocol in the existing network because of its reliable service and deployment in most of the routers. A cause of congestion may be different in wired and wireless network and needs to be handled separately. Packet delay, packet loss and time out (RTO) are not caused by congestion in case of wireless network. This has been taken into account in our consideration. To overcome the dominance of TCP, Google proposed UDP based solution to handle congestion control and reliable service with minimum latency and control overhead. In the literature several methods are proposed to classify transport layer Protocols. In this survey congestion control proposals are classified based on situation handled by the algorithm such as pure congestion, link loss, packet reordering, path optimization etc. and at the end congestion control at flow level has been addressed. © 2019 - IOS Press and the authors.
