In recent years, dynamic multi-layer networks have emerged. Unlike the regular networks, these multi-layer networks allow users and other networks to interface on different technology layers. While path finding on a single layer is currently well understood , path finding on multi-layer networks is far from trivial. Even the constraints (i.e. possible(More)
Optical or lambda exchanges have emerged to interconnect networks, providing dynamic switching capabilities on OSI layer 1 and layer 2. So far, the only inter-domain dynamics have occurred on layer 3, the IP layer. This new functionality in the data plane has consequences on the control plane. We explain this by comparing optical exchanges with current(More)
New types of exchange points, like Optical Exchanges and GMPLS exchanges have been described in the last few years. Optical and lambda exchanges are now deployed. However, these inter-connection points are not defined in systematic way in the literature. We classify interconnection points, mainly by discriminating on the properties of the control planes.(More)
This paper describes how GNU Radio software combined with the Universal Software Radio Peripheral (USRP) can be used to perform a wireless protocol analysis. GNU Radio and the USRP are an implementation of software defined radio (SDR). The design principle behind SDR is to bring the software as near to the radio antenna as possible, and to do most of the(More)
