    ModQUIC protocol performance verification with CUBIC and BBR congestion control mechanisms
    (Inderscience Publishers, 2021) Kharat, P.; Kulkarni, M.
    ModQUIC protocol is developed to compete for TCP’s dominance. In this work, ModQUIC protocol performance is evaluated using the BBR protocol and suggested a new decrease factor (?) for CUBIC protocol. Results show that ModQUIC with BBR outperforms ModQUIC with CUBIC and QUIC with CUBIC and BBR. To verify the performance of ModQUIC, a chromium server-client model-based testbed is created. The experiment result shows that throughput, delay and data rate performance of ModQUIC with BBR is superior. The performance is tested for limited and sufficient link bandwidth in presence of loss. The result analysis shows that throughput with ModQUIC/BBR improved by 6.8%, 19.06% and 27.9% over ModQUIC/CUBIC, QUIC/BBR and QUIC/CUBIC respectively whereas, a delay is reduced by 8.02%, 6.56% and 14.38% over ModQUIC/CUBIC, QUIC/BBR and QUIC/CUBIC, respectively. Overall observations conclude that the performance of ModQUIC/BBR is improved and stable as compared to ModQUIC/CUBIC, QUIC/BBR and QUIC/CUBIC. © © 2021 Inderscience Enterprises Ltd.

    Modified QUIC protocol with congestion control for improved network performance
    (John Wiley and Sons Inc, 2021) Kharat, P.; Kulkarni, M.
    In the networks, a transport layer is responsible for reliable data with guaranteed Quality of Service. A Modified-QUIC protocol provides improved throughput and reduced latency of the network. This work proposes a modification in handshaking mechanism for QUIC protocol to minimize overhead due to control signals and time required to update the congestion-window size. This modification fine-tunes the window update mechanism with the acknowledgment frame, which results in a smooth variation in the congestion-window size. This leads to the control congestion by regulating traffic in the network. In the proposed mechanism, unnecessary time out events are avoided by updating the congestion-window on receipt of the acknowledgment frame. This work has been carried out using two different testbed setups to verify the transport layer and a browser network performance. It has been observed that a Modified-QUIC protocol is easy to deploy, improves the throughput and data rate by 35% and 3.43%, respectively, over the QUIC protocol. The average fairness index is increased with a file size and for the long live traffic. © 2021 The Authors.
