“…In proSPEX, the prototype tool supporting our methodology, we use processbased discrete event simulation and statistical performance evaluation. Simulation has the advantage of being able to evaluate protocol performance according to given metrics as well as being useful in aiding in the understanding of protocol interactions [MB02].…”

The automated functional and performance analysis of communication systems specified with some Formal Description Technique has long been the goal of telecommunication engineers. In the past SDL and Petri nets have been the most popular FDTs for the purpose. With the growth in popularity of UML the most obvious question to ask is whether one can translate one or more UML diagrams describing a system to a performance model. Until the advent of UML 2.0, that has been an impossible task since the semantics were not clear. Even though the UML semantics is still not clear for the purpose, with UML 2.0 now released and using ITU recommendation Z.109, we describe in this paper a methodology and tool called proSPEX (protocol Software Performance Engineering using XMI), for the design and performance analysis of communication protocols specified with UML.

“…In order to analyze network reliability when the number of faults surpasses the bound obtained through the model described in the previous section, and also to validate that model, we built a simulation model of LITON using Simmcast [13], a Java-based network simulation framework. In addition to the protocol and mechanisms described in Sec.…”

The Internet routing layer is at times too slow at recovering from faults and makes a sub-optimal use of redundancy available at the IP layer. Overlay networks can overcome these deficiencies to provide communication infrastructures with greater availability and flexibility. The majority of current experiences, however, are able to tolerate only simple (crash) failures of the underlying network. In this paper we present LITON, an overlay network architecture that aims at providing highly available communication in spite of faults and intrusions in the network. We also present a graph-theoretic model that allows the degree of fault and intrusion tolerance of a given overlay to be determined, as well as simulation results that validate this model and demonstrate that LITON accomplishes its goal even in worst-case scenarios.

“…Moreover, while cnet offers a well designed and useful Tcl/Tk GUI, its overall architecture and event-driven programming style can be unintuitive [27]. Simmcast [30], on the other hand, offers a process-based platform similar to ours, but focuses only on providing a scalable implementation of the primitives required to effectively support group communication protocols (e.g, join, leave, send, etc. ).…”
