Static-Threshold-Limited on-Demand Guaranteed Service for Asynchronous Traffic in Timely-Token Protocol

S Ozumba, GA Chukwudebe, AB Obot


In this paper, an improved Timely-Token protocol with enhanced best-effort service for improved capacity allocation to the asynchronous (that is, non real-time) traffic is proposed. Through analytical approach and the use of computer simulations, the improved Timely-Token protocol is compared with the existing Timely-Token protocol. In particular, if AT denotes a threshold value, then, when compared to the existing Timely-Token protocol, the improved protocol will allocate additional average of AT time units to the asynchronous traffic in every cycle.
