Abstract

In this paper, System performance parameters such as throughput, blocking probability and delay have been analyzed and expressed as a function of demanding traffic and service termination, probability, and we centers our discussion at particular downlink port of satellite switch which is capable of switching the individual spot beam and processing the information signals in the packet satellite communications with demand assigned multiple access technique. Delay versus throughput as a function of traffic parameters with several service termination probability can be derived via mathematical formulation and the relative differences of transmission delay is also compared.

본 논문에서는 요구할당 다중접속 방식을 사용하는 패킷 위성통신에서 스팟빔 스위칭 능력과 신호처리 능력을 가진 위성체의 관찰중인 특정 하향링크 출력포트에 초점을 두어 시스템의 처리량(Throughput)과 블로킹 확률(Blocking Probability) 그리고 전송지연(Delay)을 요구트래픽과 채널의 서비스종료 확률에 따란 분석하였다. 수학적 검증을 통해 각 채널 서비스 종료 확률에 따라 전송지연 대 처리량 곡선을 요구트래픽 파라미터 함수로 구하였으며, 처리량에 따른 전송지연의 상대적인 차이를 비교하였다.
