A faster failure recovery mechanism for Multipath TCP
International Research Journal of Modernization in Engineering Technology and Science · 2023
In recent years, there has been an effort to change the core transmission protocol of the internet from TCP to MPTCP to better utilize the changed physical infrastructure.Multi-Path TCP (MPTCP) is relatively a new standardized transport protocol that enables nodes to utilize multiple network interfaces.However, with multiple paths comes the risk of network failures too.Link failures are quite common but they can be tackled more efficiently in MPTCP.In this paper, we present a technique that uses negative acknowledgment to accomplish faster transmission of packets.We then evaluate the proposed technique and show that it can transfer packets up to three times faster with a negligible increase in network congestion.
