초록

ATM 망에서는 어느 한 순간에 다수의 연결에서 동시에 발생하는 버스트가 일어날 수 있으며, 이는 혼잡을 야기 할 수 있다. 따라서, 사용자의 QoS를 보장하기 위해서는 반작용적인(Reactive) 흐름 제어 기법들이 필요하다. 그러나, ATM망은 고속통신망이기 때문에 중간노드에서의 혼잡에 대해서 반작용적으로 소스의 전송률을 제어하기란 쉽지 않다. 그러므로, CPN(Customer Premise Network)에서의 흐름 제어가 종단-대-종단 흐름 제어보다 더 효율적일 수 있다. 본 논문에서는 CPN에서의 흐름 제어를 위한 관리 모델을 제시하고 가상 경로 연결(VPC)을 효율적으로 이용하기 위한 새로운 망 엑세스 흐름/혼잡 제어(NAPC: Network Access Flow/Congestion Control) 기법을 제안한다.

As there can be coincident bursts which may result in congetsion in a node of ATM network, reactive flow control schemes are required to guarantee user's Quality of Service. But, the high speed characteristics of ATM networks make it difficult to control source transmission rate in reacting to congestions in intermediate nodes. Therefore, flow control in Customer Premise Network may be more efficient than end-to-end flow control. In this paper, we propose a management model for flow ontrol in CPN and new Network Access Flow/Congestsion control scheme to utilize efficiently Virtual Path Connection.
