Performance Analysis of Multipath TCP Congestion Control Variants

Abstract:

The multiple interfaces in today’s modern devices hold great promise for improving the delivery of network services over wired or wireless networks. However, the IP-coupled nature of the TCP protocol inhibits the simultaneous use of these interfaces. Multipath TCP (MPTCP) has been developed to use multiple interfaces simultaneously to provide services over the Internet. MPTCP has been implemented on systems based on Linux distributions that can be compiled and installed for use in both live and experimental scenarios. In the present work, its performance was experimentally evaluated on a real environment in the TEMONET platform, the coupled congestion control algorithms available in the Linux kernel such as LIA, OLIA, BALIA, and wVEGAS were compared, in previous work good results were obtained results in its use, but the same was obtained on symmetric paths, it has been shown that low latency communication is difficult to achieve when a device has network interfaces with asymmetric capacity and delay. Despite these results, MPTCP is still a good alternative to optimize performance through load balancing and resilience to coverage drops and link failures.
