“…In addition to being a timed-token protocol, FDDI II adds the circuit switching feature to facilitate the transmission of real-time traffic. Although it provides some degree of dynamic allocation of link bandwidth based on 16 wide band channels (WBC) [1], [2], [22], [24], [25], FDDI II still suffers (not as seriously as FDDI) the aforementioned two problems. Moreover, FDDI II underutilizes the network resources because of the use of WBCs which cannot be shared by other traffic even when they are idle.…”

Abstract-Real-time communication with performance guarantees is expected to become an important and necessary feature of future computer networks. In this paper, we present a scheme which can provide real-time communication services with both absolute and statistical performance guarantees on multiaccess bus networks for given input traffic characteristics and performance requirements. The proposed scheme reserves network bandwidth for real-time connections according to their needs. It also allows for independent addition and deletion of real-time connections while preserving existing guarantees. Our extensive simulation results for motion video communication have shown the proposed scheme to outperform the other well-known schemes.

“…Simplifying assumptions thus have to be made in order to obtain analytically tractable solutions. There are many papers on FDDI (see, for example, [ 10,11,15,17,18,22,24,25]) and IEEE 802.4 (see, for example, [12,18,5,26]), providing bounds and mean performance figures (typically throughput and mean waiting time). Takagi [22] studies the effect of the token rotation timer on the delay-throughput performance of a symmetric single buffer system operating under a timed-token protocol.…”

Download date: 13. mei. 2018 AbstractThe IEEE 802.4 and FDDI (Fibre Distributed Data Interface) standards are high speed MAC (Medium Access Control) protocols for LAN/MANS employing a timer-controlled token passing mechanism, the so-called Timed Token Protocol, to control station access to the shared media. MAC protocols belonging to the class of timed token protocols support synchronous and real-time (i.e., time-critical) applications, and provide priority among asynchronous (i.e., non time-critical) applications. During the last few years, a lot of research has focused on the study of timed token protocols to obtain performance measures such as throughputs or mean waiting times. The recent development of the Power-Series Algorithm (PSA) has opened new perspectives in the analysis of this class of protocols. This paper shows the versatility of the PSA technique to evaluate the station buffer occupancy and delay distributions of a very general model which can be used to represent the behavior of several LAN/MANS MAC protocols, among which the timed token MAC protocols. Specifically, the focus of the paper is on the solution of an almost exact model of the IEEE 802.4 MAC protocol. Since the model we propose and solve numerically by exploiting the PSA technique is an approximate model of the FDDI MAC protocol, the paper also reports on a comparison between performance measures obtained for this model and simulation results for the corresponding (exact) model of FDDI.

With the continuing success of Local Area Networks (LANs), there is an increasing demand to extend their capabilities towards higher data rates and wider areas. At high data rates and long distances the packet transmission time may become comparable or significantly less than the network propagation delay. For this reason Medium Access Control (MAC) protocols which were developed for LANs are no longer viable. Together with the progress in fiber optic technology, this has given rise to the so-called Metropolitan Area Networks, or MANs. These can span much greater distances than current LANs, and offer data rates in the region of hundreds of Megabit/sec (Mbps). This survey first sketches the problems encountered in using the MAC protocols defined for LANs on higher-speed and longer-distance networks; and then it focuses on two MAC protocols (FDDI and DQDB) developed for MANs by standardization bodies. These two MAC protocols represents two different approaches to overcome the limits of LAN MAC protocols. FDDI represents the evolution of the token passing class of MAC protocols, while the latter is a new brand of MAC protocol with a completely distributed control. This survey focuses on both MAC protocols with particular attention on their performance analysis.
