Abstract

We discuss a new packet service paradigm, called "Less Impact Better Service” (LIBS), which is realized through a novel queuing discipline, called "Noncongestive Queuing” (NCQ). NCQ prioritizes small packets when conditions permit and utilizes service thresholds to confine the delay impact of prioritization on congestive applications. We show that LIBS and NCQ satisfy more users with diverse demands on delay and throughput. We obtained both analytical and simulation results, which are very promising. Diversity is simulated by using FTP, sensor, and VoIP traffic.
