Abstract
The Integrated Services Packet Networks are designed to offer new network services to a wide variety of applications. The architecture behind the new services consists primarily of a packet scheduler, a packet classifier, admission control, and a reservation establishment protocol. This paper describes a complete implementation of this Traffic Control extensions. We also designed and implemented a kernel interface which permits to send Quality of Service (QoS) requests to the network layer. We explain how the elements of the architecture work in concert and which mechanisms we use to guarantee a requested amount of bandwidth. Our scheduler uses a variant of the Class Based Queuing mechanism (CBQ) of Sally Floyd and Van Jacobsen [6]. For the reservation signaling and establishment we use RSVP [2]. Finally this paper provides a performance evaluation of the proposed mechanisms.Keywords
