MULTIPATH TCP TECHNIQUES FOR DISTRIBUTED COMPUTING SYSTEMS

摘要

In non-limiting embodiments described herein, multipath TCP can be implemented between clients and servers, the servers being in a distributed computing system. Multipath TCP can be used in a variety of ways to increase reliability, efficiency, capacity, flexibility, and performance of the distributed computing system. Examples include achieving path redundancy, connection migration between servers and between points-of-presence, end-user mapping (or -remapping), migration or path redundancy for special object delivery, and others.

1. A method of establishing a multipath TCP connection, comprising:
at a first server, receiving from a client device one or more handshake messages indicating multipath TCP support, and in response thereto, establishing a first subflow of a TCP connection between the first server and the client device; the first server sending an add address message to the client device over the first subflow, the add address message including an address of a second server, the second server being physically separate from the first server; the second server receiving from the client device one or more multipath join messages and in response thereto establishing a second subflow of the TCP connection between the client device and the second server.
