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 Situation-Based Congestion Control Strategies for Wired and Wireless Networks(Institute of Electrical and Electronics Engineers Inc., 2018) Kharat, P.; Kulkarni, M.Performance of transport layer is measured mostly in terms of packet delivery ratio, transmission delay, and throughput. Congestion control (CC) strategies are responsible for transport layer performance. There are different congestion control algorithms are designed and developed by researchers to handle shared, highly distributed and heterogeneous environment. In this paper, we are analyzing most of the popular congestion control algorithms based on link state, type of traffic, mode of transmission and bandwidth delay product (BDP). In the proposed algorithmic solutions, networking researchers not only looking for congestion but also taking care of effective use of network resources in different types of environments such as wired, wireless, high-speed, long-delay, etc. To avoid severe congestion based on feedback mechanism few packets are dropped randomly by using active queue management (AQM) techniques. Using explicit congestion notification (ECN) mechanism unnecessary packet dropping is avoided. Data center network (DCN) uses a different approach to handle congestion. © 2018 IEEE.
