Bug fixes slated for 2.0.3

• Other well contained patches?

Features and enchancements for 2.1

• UDP out of order count
• Shell script wrapper for non-interactive tests

Iperf 2.2

• What else?

ESxSNMP and TSDB

• ESnet's new SNMP data collection
• Why? Need for lossless collection of data
• TSDB:
  • can be used for any time series data
  • optimized for quick data access
  • aggregation functions: min, max, sum, etc
  • Pure python (for now)
  • Open source, available very soon
• Hybrid approach: SQL for metadata, TSDB for time series data
