본 논문은 이동망에서의 고화질 멀티미디어 서비스들이 언제 어디서나 자유롭게 끊김없이 서비스 되기 위해 요구되는 이동성 및 QoS 기술에 기술하고 있다. 이를 위해 네트워크 장비는 이기종 망간의 핸드오버를 위한 IP 이동성 기술과 이동성 서비스별로 플로우를 구별하여 QoS를 보장해 줄 수 있는 기술이 구현되어야 하고, 더 나아가서는 플로우 별 핸드오버를 가능하게 하는 Flow Mobility 기술이 요구된다. Flow Mobility 기능은사용자의 서비스 품질을 만족시킬 뿐 아니라 네트워크의 상태에 따라 대역폭을 많이 요구하는 플로우를 offload 시킬 수 있는 기술로 사용 가능하다 . 본 논문에서는 네트워크 장비에서의 Flow Mobility 구현 방안에 대하여 제안한다.
