polling mode
4.This paper reviews the polling systems used in entworks. According to these, a polling system used in BISLN(Broadband Integrated Service Local Network) based on ATM(Asynchronous Transfer Mode) is designed. At the same time, this polling system model used in BISLN prototype is realized in our aboratory.
6.Under the mode with a single processor,finite internal storage capacity relative to infinite increment of quasi-real-time strategy table in theory is difficult to meet the requirements of real-time polling in internal storage. The virtual memory technology is used in this article. Through specific election mechanism,dynamic adjusting is applied to real-time strategy tables which are in the internal strategy table base according to the actual situation of variable electrical power system operation method.
