This research note presents the results of a simulation study on the performance of a new protocol suitable for use in a Gbit/s MAN. Performance is simulated under a range of traffic types, access allocation algorithms, number of stations, and an overload condition. The results show that the protocol is very efficient, capable of achieving utilization close to 100% without stations incurring excessive mean message delays. It is also fair to almost all stations under conditions of underload and overload.

Performance evaluation of the register insertion protocol for voice-data integration
1997, Computer Communications
The performance of the register insertion protocol for mixed voice-data traffic is investigated by simulation. The simulation model incorporates a common insertion buffer for station and ring packets. Bandwidth allocation is achieved by imposing a queue limit at each node. A simple priority scheme is introduced by allowing the queue limit to vary from node to node. This enables voice traffic to be given priority over data. The effect on performance of various operational and design parameters such as ratio of voice to data traffic, queue limit and voice packet size is investigated. Comparisons are made where possible with related work on other protocols proposed for voice-data integration. The main conclusions are: (a) there is a general degradation of performance as the ratio of voice traffic to data traffic increases, (b) substantial improvement in performance can be achieved by restricting the queue length at data nodes and (c) for a given ring utilisation, smaller voice packets result in lower delays for both voice and data traffic.
