AMIS Project Objectives• 40+Gbps flow-granularity network measurement

instrument– 216-core network processor + multicore x86

• Software defined measurement APIs & libraries– Flexible specification of measurement targets and

metrics

• Preserving privacy of network flow data– Workload-aware privacy protections

• In-depth flow analytics– Project/AS utilization, patterns and trends

Measurement Data Management and Processing

• Decentralized hierarchical resource management

• common data integration schema to be used across analytic, communication, and storage components

• Distributed system for high volume streaming data processing

• GUI, reporting tools, data repo

7

Network Flow Analytics

• Distinguish traffic matrix and traffic types– identify project association of traffic flows– file transfers, interactive sessions, short-lived

• Stochastic modeling– descriptive statistics– auto-correlation

• Derive network activity patterns and trends• Provide insights to network management

– What if scenarios
