US Army FCS networks are made up of MANETs

How to manage and efficiently utilize so many (500+) nodes?

Current network management tools are designed for the Internet, relying on plentiful bandwidth and steady connectivity

• "No route to host" cannot be considered an exception for MANET software

Hierarchy of policy agents (global, domain, local)

• Recursive clusters, planned a priori; every node is given the hierarchy
  • Hierarchy generally follows network structure or human structure
• Cluster may split and join dynamically

Network management data travels hierarchy

• Data is pushed up, following reporting/filtering policies for transmission and forwarding
• Policies are pushed down

Lots of talk on their emulation and software-in-the-loop (SITL) setup

• Discrete Linux hosts connected to OPNET for phy/mac/net emulation

Compares against more traditional SNMP

• SNMP suffers due to many messages traveling multiple hops, rather than bubbling up and being filtered in DRAMA
