WirelessHART is a new standard specifically designed for real-time and reliable communication between sensor and actuator devices for industrial process monitoring and control applications. End-to-end communication delay analysis for WirelessHART networks is required to determine the schedulability of real-time data flows from sensors to actuators for the purpose of acceptance test or workload ...

We describe an efficient and accurate approximation method for calculating the bandwidth that should be allocated on each link along the path of a point-to-point MPLS connection, so that the end-to-end delay D is less than or equal to a given value T with a probability γ, that is, P(D≤T) = γ. We model a connection by a tandem queueing network of infinite capacity queues. The arrival process of ...

End-System multicasting (ESM) is a promising application-layer scheme that has been recently proposed for implementing multicast routing in the application layer as a practical alternative to the IP multicasting. Moreover, ESM is an efficient application layer solution where all the multicast functionality is shifted to the end users. However, the limitation in bandwidth and the fact that the m...

Videoconferencing is an important global application it enables people around tha globe to interact when they are far from one another. In order for the participants in a videoconfierence call to interact naturally, the end-to-end delay should be below human perception about 100 tus. Since the global propagation delay can be about 100 ms, the actual end-to-end delay budget available to the syst...

Conventional methods of discovering network topology require the cooperation of network elements. We present a method of network topology discovery based solely upon end-to-end delay measurements that requires only the cooperation of end systems. Previous work using end-to-end measurements has focused on discovering tree topologies; the method here discovers more general networks. The discovery...

Wireless communications offer an attractive option for many military, commercial as well as personal communication needs because of flexibility, cost effectiveness, and mobility. The quality features of wireless communications have led to tremendous growth in the demand for wireless networks and has led to development of novel technologies that raise the need for broadband wireless communicatio...

In this paper the end-to-end performance evaluation of a tagged session is considered through the study of a tandem queueing network. A service discipline is adopted at each queue which allows for the study of First-Come First-Served (FCFS) as well as peak-rate-enforcing multiplexing schemes. A numerical approach is presented which allows for the computation of delay, jitter and inter-departure...

Cell delay variation (CDV) is one of the quality of service parameters that can be negotiated between applications and an ATM network. The network should check during connection setup, as part of call admission control, whether it can satisfy the requested CDV of an application. For this comparison, the network should estimate the end-to-end CDV that it can support, by using local information a...

A recent result in network calculus theory provided statistical delay bounds for exponentially bounded traffic that grow as O(H log H) with the number of nodes on the network path. In this paper we establish the corresponding lower bound which shows that under these assumptions, typical end-to-end delays can indeed grow as Θ(H log H). The lower bound is obtained by analyzing the end-to-end dela...

This paper addresses the problem of finding the worst case end-to-end delay and buffer occupancy bounds in ATM networks with rate-controlled, non-work conserving servers. A theoretical framework is constructed to analyze such servers in isolation and in tandem. The analysis is based on a simple fluid model, but care is taken so that the computed delay and buffer occupancy values are upper bound...
