In this paper we present a dynamic bandwidth allocation algorithm for Ethernet Passive Optical Networks (EPON), which makes use of the Multipoint Control Protocol (MPCP) with threshold reporting and with inter- and intra-ONU priority scheduling. Three varieties of this algorithm are compared under both symmetric and asymmetric traffic conditions, by means of a detailed simulation program, regarding...
Esperase is a highly alkalophilic bacterial proteinase produced by Bacillus lentus. The enzyme hydrolyzes peptide bonds comprising the carboxylic groups of hydrophobic as well as hydrophilic residues in the oxidized insulin B chain. Some of these bonds are not attacked by other alkaline microbial proteinases. P1P4 specificity was determined by a series of peptide nitroanilides. The S1 recognition...
