Method and system of network management and protocol software architectures for mobile broadband wireless networks. One embodiment of the software architecture employs a proxy Simple Network Management Protocol (SNMP) agent at a base station in the network. The proxy SNMP agent communicates with an SNMP manager at a network management system (NMS) using SNMP messages to send Management Information Base (MIB) objects between the NMS and the base station. The proxy SNMP agent communicates with a mobile subscriber station (MSS) using media access control (MAC) messages. The protocol software architecture further includes a management plane service access point (SAP) and a control plane SAP deployed in the MSS. The architecture enables specific parameters corresponding to dynamic service flows and Quality of Service to be retrieved from and written to an MSS using proxy SNMP agents at the base stations.
