This paper deals with the distributed queue dual bus (DQDB) (IEEE 802.6) network, and makes two independent contributions. First, the unfairness problem of DQDB is addressed, and several alternative solutions that can improve the network's fairness are proposed. They include (1) the proportional assignment scheme (PR); (2) the (multiple-request)(More)
— We consider the problem of designing a logical optical network topology for a given physical topology (or fiber layout) and a given traffic demand matrix between the end-users. Traffic between the end-users is carried in a packet-switched form and the objective of our logical topology design is to minimize the maximum congestion on the logical connections(More)
To determine efficacy of continuous diazepam infusion in the treatment of refractory status epilepticus in a retrospective study, we analyzed data of 62 children admitted consecutively to our Pediatric Intensive Care Unit with a diagnosis of refractory status epilepticus. The unit followed a standard treatment protocol for diazepam infusion; if it failed,(More)
The capabilities of emerging optical technology, viz. dense wavelength division multiplexing (WDM) and tunable optical transmitters and receivers (transceivers) can be exploited to construct lightwave networks , as follows. First, by employing WDM, the huge optical bandwidth (in the order of Terahertz) is partitioned into a number of smaller capacity(More)
