Open issues and challenges in providing quality of service guarantees in high-speed networks
Jim Kurose · ACM SIGCOMM Computer Communication Review · 1993
In this paper we identify the challenges and open issues involved in providing quality-of-service (QOS) guarantees to sessions in a high-speed wide area network and briefly survey research in this area. Four approaches towards providing QOS guarantees are described and discussed: the tightly controlled approach, the approximate approach, the bounding approach, and the observation-based approach.
