ETOMIC is a network traffic measurement platform with high precision GPS-synchronized monitoring nodes. The infrastructure is publicly available to the network research community, supporting advanced experimental techniques by providing high precision hardware equipments and a Central Management System. Researchers can deploy their own active measurement(More)
Optical Burst Switching (OBS) is an optical switching technology capable of supporting large demands for bandwidth in optical backbones with Wavelength Division Multiplexing (WDM). This paper presents an OBS simulation model for the discrete event simulator OMNeT++. The performance of this model is compared with the performance of the well-known INET(More)
y muy pocas implementaciones experimentales o testbed [4][5][6][7][8][9]. Por tanto se considera importante como primer paso poder estudiar todas estas propuestas usando herramientas de simulación. Existen muchos simuladores de red [10]: el open source NS-2, el comercial OPNET, el específico para redes inhalambricas Qualnet, etc. Para este trabajo se ha(More)
This paper presents and studies objective video quality evaluation techniques for a network where frame losses can be considered independent, for example a best effort not heavy loaded packet switching network. The total or partial loss of a frame’s information affects the quality of video playback, as the frame cannot be decoded and other frames that(More)
