A software package, dxhdf5, for importing HDF5 data into OpenDX is discussed. HDF5 is a hierarchical, self-describing data format that is rapidly becoming a standard for storing large, portable data sets, such as those generated through high-performance computing. OpenDX, formerly IBM Data Explorer, is a visualization package for examining data of any(More)
We present an approximate analytical method for the evaluation of packet loss probability in synchronous optical packet-switched networks which operate under limited deflection routing with the contention resolution method based on priorities. Packets are lost because they are removed by nodes. They are removed because they experience too many deflections(More)
This paper presents an analytical methodology to obtain steady state throughput of a uniformly and fully loaded regular network. The network operates using deflection routing under the condition that a data packet is allowed to experience a finite number of deflections. Unlike the published analytical methods, the proposed method allows the analysis of a(More)
—We state a new problem of itinerant routing in elastic optical networks, which we define as the establishment and reconfiguration of an itinerant connection. In an itinerant connection, one of the connection end nodes is allowed to change. Itinerant routing could also be considered a form of connection restoration, where a connection has to be restored to(More)
—We propose an optical interconnection network with the wavelength time slot routing, a novel routing scheme that allows for a simple design of optical interconnection networks. The simulative performance evaluation shows that the proposed scheme demonstrates optimum performance at the maximum uniform exponential network load, and performs well in(More)
We present an approximate analytical method for the evaluation of packet loss probability in synchronous optical packet-switched networks which operate under limited deflection routing with the contention resolution method based on priorities. Packets are lost because they experience too many deflections and stay prohibitively long in the network. The(More)
