Inter-path OOS packets differentiation based congestion control for simultaneous multipath transmission

Abstract EN

An increase in the popularity and usage of Multimode’s devices for ubiquitous network access creates thrust for utilization of simultaneous network connections.

Unfortunately, the standard transport layer protocols used single homed congestion control mechanism for multipath transmission.

One major challenge in such multipath transmission is related to the Receiver Buffer (RBuf) blocking that hinders higher aggregation ratio of multiple paths.

This study proposed Simultaneous Multipath Transmission (SMT) scheme to avoid the RBuf blocking problem.

Realistic simulation scenarios were designed such as intermediate nodes, cross traffic, scalability or mix of them to thoroughly analyses SMT performance.

The results revealed that SMT has overcome RBuf blocking with improvement in aggregate throughput up to 95.3 % of the total bandwidth.
