자동적인 경로 전환을 통한 SCTP 프로토콜 성능 개선

Abstract

In this paper, we propose to improve the SCTP throughput based on automatic path switching between primary path and backup path. The most current domestic and abroad research is still on the theory and simulation stage. Research for the promotion and optimization on SCTP in practical networks still lags behindin the following aspects: (1) Testbed is still required for optimization of handoff execution process and handoff decision in practical physical networks. (2)Path bandwidth is required as an important parameter in some transport layer congestion control mechanisms. (3) NAT (Network Address Translation) devices, normally existing in the current IP network, are mostly not available on the SCTP protocol support, resulting in SCTP packet transmission blocking problems.
