Abstract
Today's Internet traffic is classified into realtime traffic (e.g.voice and video streaming) and non-realtime traffic (e.g.E-mail and FTP data transfer). Realtime traffic is received as a mischief which may not be able to smoothly use applications by marked delay or dropped packets when congestion occurrs as a bottle-neck link. Therefore, necessity of Qos (Quality of service) is rising. For example, allocation of network service rates and priority to realtime traffic.
In this paper, we present a new packet scheduer for the router and build control system which is intended for a best-effort (BE) flow and several constrained Qos flows. Scheduler to suggest describes a policy that satisfies delay-constrained Qos requirement of each flow and gives maximum traffic for BE flow.
