초록

본 논문에서는 인터넷 망에서 UDP를 사용하는 멀티캐스트 트래픽과 TCP를 사용하는 유니캐스트 트래픽 사이의 공정성 문제를 해결한 뿐만 아니라, 다양한 수신자들의 요구를 공정하게 충족시킬 수 있는 새로운 메커니즘을 제안하였다. 제안한 메커니즘은 송신자 위주의 일률적인 전송률 조정 부담을 지정된 서버로 분산시켰으며, 지정된 서버가 송신사의 데이타를 인터셉트하여 각 서버가 관리하늘 로컬 네트워크 상황에 맞게 독립적으로 전송률을 조절하는 방법을 사용하였다. 따라서 제안한 메커니즘을 가 수신자들의 상황을 보다 정확하게 판단하여 서비스를 제공할 뿐만 아니라, 기존의 유니캐스트 세션과의 공정한 네트워크 자원 공유를 실현하였다.

In this paper, we proposed a new mechanism that solves the fairness problem between unicast traffic using the TCP and multicast traffic using the UDP, and satisfies the requirement of various receivers fairly in the Internet. The proposed mechanism decentralizes the load of blanket transmission rate control from sender to designated server, and uses the method that talc designated server intercepts the sender's data and controls the transmission rate suitable for it's local network. Therefore, the proposed mechanism not only provides multicast service by accurate estimation of the network status of each receiver, but also realizes both the inter-session fairness and the intra-session fairness problem.
