We investigate how path failure influences Concurrent Multipath Transfer (CMT) using SCTP multihom- ing. We show that CMT suffers from significant ''receive buffer blocking" which degrades performance during both permanent and short-term failure. To improve performance, we introduce a new ''Poten- tially-Failed" (PF) destination state, and revise CMT's failure detection and (re)transmission policies to include the PF state. Using simulation, we demonstrate that the modification called CMT-PF outperforms CMT during failure - even with aggressive failure detection thresholds and varying receive buffer con- straints. In non-failure scenarios, CMT-PF performs on par or better but never worse than CMT. Finally, we confirm these simulation results using FreeBSD implementations of CMT and CMT-PF. Based on our findings, we recommend CMT-PF be used in existing and future CMT implementations and RFCs. |
