Abstract
IPv6 네트워크에서 SCTP를 기반으로 하여 트랜스포트 계층에서 이동성을 지원하는 방안을 제안하였다. 제안하는 방안에서는 단말의 이동에 따라 SCTP 연결에 매핑되는 종단 주소를 변경하기 위한 적절한 시점을 판단하는 기준을 제안하였고, 핸드오버에 효율적으로 대처하는 오류 복구 메커니즘을 제안하였다. 또한, 수치적 분석을 통해 기존 SCTP에 비하여 제안하는 방안이 핸드오버 지연과 손실복구시간을 줄임을 보였다. In this paper, we propose an approach to transport layer mobility support leveraging the SCTP extension dubbed dynamic address reconfiguration in IPv6 networks. Timing issues related to the end-to-end address management, and a novel error recovery mechanism associated with a handover are discussed. The proposed error recovery mechanism is analyzed and compared to that of the plain SCTP to show that it reduces the handover latency and error recovery time.
