SCTP는 TCP와 마찬가지로 연결 지향적이며 신뢰성 있는 데이터의 전송을 위한 전송 계층 프로토콜이다. SCTP는 오류 및 플로우 제어 등 많은 부분에 있어서 TCP의 방식을 그대로 따르며, 거기에 더하여 멀티스트리밍과 멀티호밍 특성을 가진다. 이 논문에서는 TCP와 다른 대표적인 특징들 중 멀티호밍이 성능에 미치는 영향을 살펴 보았다. 먼저 프로토콜간의 성능 비교를 통해서는 SCTP 프로토콜이 TCP와 다른 혼잡 제어 메커니즘을 사용함으로 인해 TCP Reno나 TCP SACK에 비해 향상된 성능을 보임을 확인할 수 있었다. 또한, 멀티호밍을 지원하는 경우 현재의 SCTP의 재전송 정책이 프라이머리 경로와 대체 경로간의 경로 특성의 따라 성능 저하를 가져올 수 있는 잠재적인 문제점을 가짐을 확인하였다.
