Unique Packet Identifiers for Multipoint Monitoring of QoS Parameters

Juraj Giertl, František Jakab

Gorazd Baldovský, Ján Genči


Content

  • Introduction to QoS parameters monitoring

  • The BasicMeter Project

  • Unique packet identifiers

  • Experiments

  • Future plans


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


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


Multipoint Monitoring

  • Parameters requiring more than one metering point

    one way delay

    jitter

    packet loss

  • Multipoint monitoring with packets identification


Requirements to Identifiers

  • Uniqueness of identifiers

  • Length of identifiers

  • Data security

  • Speed of identifiers generation


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.


Identifier Generation


Conclusion - Results of Experiments (1)

  • Test of collisions occurrences


Conclusion - Results of Experiments (2)

  • Test of performance


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
