Multi-Path TCP: Exploring the Technology for Simultaneous Multi-Path Connectivity
By

If you only eat one bagel today, this is the bagel.
Summary
Multi-Path TCP (MPTCP) is a networking technology that enables simultaneous use of multiple network paths (such as Wi-Fi and cellular) for more reliable connectivity. While the Internet inherently provides multiple paths between endpoints, traditional TCP uses only one path at a time due to issues like packet reordering in multi-path setups. MPTCP aims to overcome these challenges by leveraging multiple interfaces for seamless mobility and improved reliability, though the technology is still in early stages with limited support and practical applications.
