SLA를 지원하는 웹 서버 부하 분산 기법 = A Web Server Load Balancing Mechanism for Supporting Service Level Agreement

국문 초록 (Abstract)

클라이언트와 서비스 제공자간의 서비스 수준 계약인 SLA(Service Level Agreement)를 만족시키기 위해서는 클라이언트 요청을 우선순위 계층으로 구분하여, 낮은 수준의 서비스를 요청하는 클라이언트 보다는 고수준의 서비스를 요구하는 클라이언트에게 우선적으로 서비스를 제공할 수 있는 기술이 필요하다. 본 논문에서는 서비스 제공자의 웹 서버 노드를 우선 순위에 따라 정적·동적으로 분할하는 방법 다중계층(Multiclass)에서의 승인 제어(Admission Control) 기법을 연구하였으며, 시뮬레이션을 통해 SLA를 고려한 웹 서버 처리율 및 응답시간 성능을 분석하였다.

다국어 초록 (Multilingual Abstract)

To satisfy SLA(Service Level Agreement) contract between a client and a service provider, the client requests are classified and processed by priorities. In providing differentiated service, a request from a client who has low priority can be dealt with less important. In this paper, we study static and dynamic partitioning mechanism of web servers and also admission control policy for multiclass request distribution. Through simulation experiments, we analyze web server throughput and response time considering SLA.
