Abstract
Admission Control is a vital component for end-to-end Quality of Service (QoS) delivery in a
packet flow network. It is more effective when implemented at the edge of the network. The
edge of a mobile network is dominated withmultiplexer which either uses Synchronous Digital
Hierarchy (SDH) or Wavelength Division Multiplexing (WDM) for transport. The edge of the
carrier Ethernet network suffers QoS due to packet loss and underutilization of bandwidth.
Measurement-Based Admission Control (MBAC) Algorithm which reduced the IP Packet Loss
Ratio (IPLR) of WDM system by 30.36% and SDH system by 25.34% was setto be achieved in
this work. The developed Algorithm was also set to improve the bandwidth utilization of WDM
system by 30.36% and bandwidth utilization of SDH system by 25.34%. The developed
Algorithm was implemented using C-sharp (C#) platform. Based on the simulation results,
WDM system IPLR was reduced by 30.36% and SDH system IPLR was reduced by 25.34% as
compared to the measured data from the network result before implementation of the MBAC
algorithm. WDM system bandwidth utilization was improved by 30.36% and SDH system
bandwidth utilization was improved by 25.34% as compared to the baseline result before
implementation of the MBAC Algorithm. From the t-test results obtained, the probability levels
(P-values) of IPLR and bandwidth utilization for both edge systems were less than 0.05. This
implied that the developed Algorithm has better performance in comparison with the measured
data from MTN Lagos network.
