Network management IEX8175 RF Electronics
DARPA ISAT Beyond traditional "tactical" which is voice/human user oriented High reliability delivery Beyond traditional ad-hoc networks
Densely connected heterogeneous network Modern communication network
Moore graphs Harary graphsCirculant graphs Good network graph topologies Good for benign scenarios Mostly circulant graphs Only few Moore graphs actually exist.
Robust Dynamic Network (space-ground) Capability Stress level robust networks current networks Security architecture for all layers and across-layers Architecture good for multiple generations of technologies
Measure, Model, and Control Topology/ Configuration Offered traffic Changes to the network Operational network Models, tools, scripts, databases measure control Network Management Dials Knobs
Algorithm For Setting the Knobs Random Early Detection (RED) –Several tunable parameters –Min and max thresholds on queue length, max probability, queue weight Average Queue Length Probability
Traffic engineering –Forward traffic in inverse proportion to path costs –Leads to polynomial-time optimization problems
Policy-based Network Management
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
Is management really that important?
