  1. Network managementIEX8175 RF Electronics avo.ots@ttu.ee avots@lr.ttu.ee

  2. DARPA ISAT • Beyond traditional "tactical" which is voice/human user oriented • High reliability delivery • Beyond traditional ad-hoc networks

  3. Modern communication network Densely connected heterogeneous network

  4. Good network graph topologies • Good for benign scenarios • Mostly circulant graphs • Only few Moore graphs actually exist.

  5. Robust Dynamic Network (space-ground) robust networks Capability currentnetworks Stress level Security architecture for all layers and across-layers Architecture good for multiple generations of technologies

  6. Measure, Model, and Control Network Management Models, tools, scripts, databases Knobs Dials Offered traffic Changes to the network Topology/ Configuration measure control Operational network

  7. Algorithm For Setting the Knobs • Random Early Detection (RED) • Several tunable parameters • Min and max thresholds on queue length, max probability, queue weight Probability Average Queue Length

  8. Traffic engineering • Forward traffic in inverse proportion to path costs • Leads to polynomial-time optimization problems 2 1 3 1 3 2 1 5 4 3

  9. Policy-based Network Management

  10. Architecure • QoS service is provided through a policy server • The edge routers consult the policy server to perform admission control • The core routers accept resource configurations from the policy server to implement QoS requirements

  11. Is management really that important?
