In the Remote Device Management (RDM) protocol, lighting devices are discovered by conducting a simple binary search based on the 48-bit Unique ID (UID). However, the existing binary search scheme tends to require large delay for device discovery. In this paper we propose a partition-based discovery scheme in RDM. From numerical simulations, we can see that… (More)
—The Remote Device Management (RDM) protocol is used to manage the devices in the lighting control networks. RDM provides bi-directional communications between a controller and many lighting devices over the DMX512-A network. In RDM, using a simple binary search scheme, which is based on the 48-bit unique ID (UID) of each device, discovers the lighting… (More)
The capacity upgrading techniques to 40 Gb/s channel rate using the existing N times 10 Gb/s based DWDM infrastructure were studied. The super-FEC, carrier- suppressed return-to-zero and pre-emphasis were applied to 40 Gb/s channels for improvement in optical signal to noise ratio sensitivity.
