A new technique for link utilization estimation in packet data networks using SNMP variables
S. Amarnath, Anurag Kumar · 2002
On-line estimation of performance measures, such as the utilization of a digital communication link, is useful in the monitoring and management of packet data networks. We define a notion of link utilization when the packet arrival process at the link is nonstationary. We develop a scheme for accurate monitoring of the link utilization, using the easily available SNMP variables. Simulation results and on-line measurement results on a link carrying live traffic in a wide area data network are provided.
