SNMP, SNMPv2 and SNMPv3 are the standard protocols for network management in traditional wired networks. New RFCs have updated SNMP, but it remains focused on high-availability, high-bandwidth networks. In the dynamic MANET of tactical edge networks, fast-moving aircraft and terrain obscuration combine to create conditions where traditional SNMP is less effective. In this paper, we propose innovative ways to improve SNMP agent/manager interactions, specifically addressing the limitations of a bandwidth constrained tactical edge network. We will analyze the performance improvements using a variety of aggregation techniques of multicast, reliable multicast and aggregation techniques to enhance the SNMP agent/manager interactions thus conserving bandwidth but still monitor and provide network situational awareness to the war fighter. Performance analysis will be conducted through a combination of simulation and emulation environments, and the results will be discussed.
