Abstract


Abstract

The edge of mobile networks dominated with multiplexers which either use Synchronous Digital Hierarchy (SDH) or Wavelength Division Multiplexing (WDM) for transport experience packet loss due to underutilization of bandwidth during packet flow. To resolve this problem, a Measurement Based Admission Control (MBAC) algorithm was implemented on the multiplexer for edge carrier Ethernet network to improve the bandwidth utilization. The developed algorithm was implemented using C-sharp (C#) platform. Based on the simulation results, the bandwidth utilization of the WDM system was improved by 30.36% and that of the SDH system was also improved by 25.34% when compared to the results obtained from the measured data from the network before the implementation of the MBAC algorithm. From the t-test results obtained, the probability levels (P-values) of bandwidth utilization for both the edge systems were less than 0.05. This means that the developed algorithm has achieved better bandwidth utilization than that of the measured data from MTN Lagos network.
