ABSTRACT
Fairness and QoS have been main concerns in designing modern routers or switches in multimedia environment. This paper proposes a new packet-based fair queuing algorithm for packet switches called VISTA (Virtual Clock with Virtual Start Time Alignment) to improve fairness in existing VC (Virtual Clock) algorithm. A novel concept of virtual start time alignment is introduced to improve fairness of VC algorithm and to reduce the computing complexity to constant time with a hardware-based earliest Packet Selector (EPS).
