Abstract—This research presents an advanced model of WiMAX Adapter. The proposed Adapter architecture can serve multiple adaptive applications and processes by utilising a convergence mechanism to differentiate the conversations with each utilised vendor equipment. This paper presents the Adapter architecture, and experiments for the efficient use of the system bandwidth for the management purposes. The experiments are focused on the aggregation of SNMP monitoring requests on WiMAX link. The derived aggregation results point a radical gain that can be achieved in SNMP monitoring when requesting more data at once. For WiMAX link the maximum goodput increase due to applied aggregation was 45-folds and for Ethernet link 6-folds. Even the lower aggregation levels lead to good results for both. This research motivates the use of a general Adapter solution for WiMAX technology, but also supports the vendor specific management approach. The WiMAX Adapter solution also supports both the user-end (UE) and the network controlled management approaches in the limits of the user privileges.
