By Andrzej Kwiecien, Piotr Gaj, Piotr Stera

This e-book constitutes the completely refereed court cases of the twenty first foreign convention on machine Networks, CN 2014, held in Brunów, Poland, in June 2014. The 34 revised complete papers provided have been conscientiously reviewed and chosen for inclusion within the e-book. The papers in those court cases disguise the subsequent issues: machine networks, tele informatics and communications, new applied sciences, queueing idea, cutting edge functions and networked and IT-related facets of e-business.

Czachórski Table 2. 203×10−7 Table 3. 569×10−7 Table 4. 020 4×10−6 Table 5. 893 4×10−6 Modeling Packet Traffic 6 35 Conclusions This paper illustrates how a superposition of two-state MMPP’s can be fitted to a rate and variance time curve of measured traffic traces. The fitting algorithm for matching asymptotic second-order self-similarity was described in detail. This article also shows how to obtain the set of descriptors from real traffic traces using Bellcore Morristown Laboratory data and IITiS traffic trace.

W } sˆw i ≥ Δbi w min wmin : sˆw = min {ˆ s : w ∈ {1, . . , W }} in other case i i (2) (1) (2) where Δbi = τi − bi , and τi is the moment the request ui leaves the QM. According to the Formula (1) the Web server with the lowest index, which is able to service the request in a time not longer than Δbi , is chosen. If there is no such server, the server offering the shortest service time is chosen. Thanks to this solution, Web servers with the lowest indexes are the most loaded but, still able to service requests, and the servers with higher indexes are unloaded and able to service requests very quickly, when necessary.

DPI is not perfect – as shown by Dusi et al. [11] – but it is the most popular method used in the literature, and often the only practically available. The libprotoident v. 7 was used as the DPI software (reported to offer very good accuracy in [12]). The Unibs dataset already contained ground-truth and was not suitable for DPI because of no payload data. 20 P. Foremski, C. Callegari, and M. g. incomplete TCP sessions and empty UDP flows. The datasets contain different subsets of network protocols (see Table 1).
