Abstract: Techniques are presented herein to distribute the processing of communication to network-connected devices to routing nodes, as opposed to centralizing those operations in one device as in the traditional/classical system. Using a bitmapped Type field, advertisements and queries can be categorized. Also, by using a Subgroup field, the scope of advertisements and queries can be dynamically limited. These techniques reduce the number of matches and make the matches more relevant to the user who sent the query. Routing nodes can be any network element that routes traffic, physical or virtual (cloud-based router or switch). The intelligence to perform these techniques can be embodied as an overlay on top of a physical network.

Abstract: A device for detecting a weather condition, particularly a tornado. The device includes a receiver module configured to receive electromagnetic signal from an atmosphere, particularly electromagnetic signal in the range of 1 MHz to 100 MHz. The device also includes a processing module coupled to the receiver module and configured to generate frequency spectrum data corresponding to the received electromagnetic signal, such as by performing a Fast Fourier Transform operation. Frequency spectrum data corresponding to the weather condition desired to be detected is stored in a stored data module. The device also includes a comparison module for comparing, such as by performing a cross-correlation operation, the generated frequency spectrum data and the stored frequency spectrum data in order to determine whether the weather condition is present in the atmosphere.
