3.6 Network Management Reference Model

3.6 Network Management Reference Model

The 802.16f amendment ^[8] provides enhancements to IEEE 802.16-2004, defining a Management Information Base (MIB) for the MAC and PHY and the associated management procedures. This document describes the use of a Simple Network Management Protocol (SNMP), an Internet Engineering Task Force (IETF) protocol (RFCs 1902, 1903, 3411-5 and 3418), as a network management reference model.

802.16f consists of a Network Management System (NMS), managed nodes and a service flow database (see Figure 3.4). BS and SS managed nodes collect and store the managed objects in the format of WiressMan Interface MIB and wmanDevMib, defined in the 802.16f document, which are made available to NMSs via management protocols, such as the Simple Network Management Protocol (SNMP). The service flow database contains the service flow and the associated QoS information that need to be associated to the BS and the SS when an SS enters into a BS network.
