Analysis of a high-performance mobile access to a computing cloud using MPTCP protocol and IEEE 802.11ac network
Agnieszka Chodorek, Robert Ryszard Chodorek · 2017
As was reported in the literature, TCP transmissions in an LTE network cannot fully utilize available bandwidth due to the limitations of TCP's mechanisms. Historically, a similar situation - but more spectacular - was observed in the beginning of the 1990s, during the first real (not simulated or emulated) TCP transmissions over newly introduced ATM networks. In the paper we test behavior of the multipath TCP (MPTCP) protocol over IEEE 802.11ac WLAN using real network equipment. Experiments were carried out in a test private cloud, built using the OpenStack open source cloud system. In experiments, a mobile node accessed the cloud using the MPTCP protocol working over two 802.11ac links. The performed tests covered multipath access to the cloud with the use of dedicated links and shared links, as well as migration of the cloud's data following the mobile node which changed its point of attachment to the cloud.
