  1. Unique Packet Identifiers for Multipoint Monitoring of QoS Parameters Juraj Giertl, František Jakab Gorazd Baldovský, Ján Genči

  2. Content • Introduction to QoS parameters monitoring • The BasicMeter Project • Unique packet identifiers • Experiments • Future plans

  3. Quality of Service in Computer Networks QoS parameters of network traffic • Volume parameters • bandwidth • packet rate • packet loss • Time parameters • one way delay • jitter (delay variation) • round-trip time

  4. The BasicMeter Project • BEEM BasicmEter Exporting and Metering Process • JXColl Java XML Collector • BM Analyzer BasicMeter Analyzer • ACP Analyzer Collector Protocol • AEP Analyzer Exporter Protocol

  5. Multipoint Monitoring • Parameters requiring more than one metering point one way delay jitter packet loss • Multipoint monitoring with packets identification

  6. Requirements to Identifiers • Uniqueness of identifiers • Length of identifiers • Data security • Speed of identifiers generation

  7. IP Packet Analysis • IP packet structure • suitable fields for identifiers generation header length, total length of packet, identification, protocol, source IP address, destination IP address.

  8. Identifier Generation

  9. Conclusion - Results of Experiments (1) • Test of collisions occurrences

  10. Conclusion - Results of Experiments (2) • Test of performance

  11. Future Plans • improvement of effectiveness of identifiers generation • elimination of repeating hardly predictable same packets • implementation of extensions of BasicMeter interface for intrusion detection systems traffic engineering usage-based billing and accounting • implementation of adaptive sampling into BEEM • MPLS support • IPv6 support
