A path characteristics based adaptive subflow switching algorithm for dynamic heterogeneous MPTCP network

to improve throughput. However, MPTCP cannot adjust the access state of subflows in real time according to the actual situation in the dynamic network, resulting in poor performance under the limitation of limited buffers. The existing path management algorithms, such as Fullmesh and PCDC, only select the subflows for concurrent transmission at the beginning, and cannot dynamically manage the subflow during the transmission. Therefore, we propose a path characteristics based adaptive subflow switching management (PASS) algorithm to manage multiple paths of MPTCP in real time and dynamically manage whether a subflow joins the transmission or not. Experimental results show that PASS is more stable and flexible than traditional Fullmesh algorithm and PCDC algorithm, and can obtain higher network throughput.
