New technique for the representation of access network performance

Many large data communication systems can be conveniently divided into core and customer access network arrangements. The design of the latter, with statistical multiplexers and leased line or dial-up access, is often neglected in terms of optimum arrangement. This is simply because the attachment of users to the system is effected in an ad hoc manner, over a period of time, and is highly susceptible to physical changes and variability in traffic demand. More attention is now being given to this relatively expensive resource, especially as the quality of service, in terms of delays and blocking, are an increasingly important part of service level arrangements between the value added network supplier and customer. This paper presents a new technique, suitable for a wide range of queuing systems, that aids the optimal design of star type networks where the quality of service constraints must be taken into consideration.
