Abstract
본 발명은 패킷 네트워크, 특히 비동기식 전송 방식(ATM) 네트워크에서 사용하기 위해, 접속 설정시에 최소 대역폭을 필요로 하는 접속 트래픽을 지원하기 위한 방법 및 장치를 개시하고 있다. 또한 상기 방법 및 장치는 접속 설정시에 최소의 대역폭 또는 확보된 고정 대역폭을 필요로 하거나, 대역폭을 필요로 하지 않는 접속을 포함하는 어떠한 혼합된 트래픽을 지원한다.The present invention discloses a method and apparatus for supporting connection traffic requiring minimum bandwidth in connection establishment, for use in packet networks, in particular asynchronous transmission mode (ATM) networks. The method and apparatus also support any mixed traffic, including connections that require a minimum bandwidth or a fixed fixed bandwidth when establishing a connection, or that do not require bandwidth.
본 발명은 초소 서비스 접속을 확보된 최소 대역폭에 대응하는 속도에 이르도록 스케줄링하기 위해 절대 시간에 의해 트리거되는 제1스케줄러(a first scheduler)와, 두개의 스케줄링 구성체간의 통신을 위한 제2스케줄러 및 최소 서비스 접속 식별자의 큐우(queue)로 이루어진다.The present invention provides a first scheduler triggered by an absolute time to schedule the service service connection to a rate corresponding to the minimum bandwidth secured, a second scheduler and a minimum scheduler for communication between the two scheduling constructs. It consists of a queue of service connection identifiers.
본 발명은 이중 스케줄링 메카니즘(dual scheduling mechanism)을 통해, 접속 설정시에 최소 대역폭을 확보하기 위한 접속에 대한 최소 대역폭은 접속 경로의 각각의 포인트에서 보증되며, 잔류하는 공유 대역폭의 오차 레벨은 상기 제2스케줄러의 품질에 따라 항상 달라진다.According to the present invention, through a dual scheduling mechanism, the minimum bandwidth for the connection to ensure the minimum bandwidth at the time of connection establishment is guaranteed at each point of the connection path, and the error level of the remaining shared bandwidth is determined by the above-mentioned. It always depends on the quality of the scheduler.
