• COMPARISON OF SNMP AND NETCONF BASED NETWORK
  MANAGEMENT TO USE IN TACTICAL NETWORKS

2
Goals Comparison of SNMP and NETCONF

• Functionality
• data modeling, protocol operations, error
• reporting, security mechanisms etc.
• Performance
• communication overhead in tactical networks

3
Tactical Network

• Links
• HF radio 1200 b/s
• VHF radio 2400 b/s
• radio relays 2-8 Mb/s

SNMP Implementation

• Experience
• ATM switch agent
• Proxy agents for transmission devices
• Problems and solutions
• Error reporting
• extension MIB
• Configuration management
• additional manager functions (did not work well)
• Transactions
• garbage collection by a manager

Conclusions

• SNMP
• the de facto standard for tactical networks
• protocol maturity, development deployment
  experience, development tools
• NETCONF
• little experience
• communication overhead
• possible solution XML compression
• processing overhead (embedded devices)
• possible solution proxy agents
