Introduction (1)

• EuQoS Project End-to-End Quality of Service
  Over Heterogeneous Networks
• EU FP 6 IST Integrated project with over 25
  organisations www. euqos.eu
• Objective to develop solution for providing
  strict end-to-end QoS in multi-domain,
  heterogeneous network (build over WiFi, xDSL,
  UMTS, LAN, IP core)
• Approach to define an architecture, following
  DiffServ and NGN, that allows to control the
  network and enforce QoS required for traffic
  flows generated by users

• Main components
• signalling system allows users to setup/release
  QoS connections on demand
• end-to-end Classes of Service (CoS) that provide
  adequate QoS for different types of traffic, e.g.
  Telephony, RT Interactive, Multimedia Streaming,
  High Throughput Data, Low Latency Data, Standard
  
• Monitoring and Measurement System (MMS) that
  support EuQoS system functions CAC, TERO, OAM

Monitoring and Measurement System in EuQoS (1)

• performing trials of EuQoS system in testbed
• to prove that EuQoS Classes of Service provide
  adequate QoS guarantees
• to evaluate the performance of EuQoS system
  (signalling, resource provisioning, etc.)
• supporting EuQoS system functions
• Call Admission Control (CAC)
• to make CAC algorithm less preventive
  (Measurement Based Admission Control)
• to provide information about available QoS
  routing paths
• Traffic Engineering and Resource Optimization
  (TERO)
• to provide data for resource provisioning and
  optimization
• Operation, Administration and Maintenance (OAM)
• to on-line monitor QoS offered by CoSs

MMS includes tools for

Monitoring and Measurement System in EuQoS (2)

• MMS tools for trials
• Problems with tools for evaluation of Classes of
  Services
• There is a number of tools for measuring QoS
  parameters, but they do not address QoS
  objectives of CoSs
• incompatible definition of QoS parameters, like
  IPTD, IPDV, IPLR, throughput
• traffic models used in generators do not
  correspond to traffic profiles assumed by Classes
  of Services, e.g. Multimedia streaming, Real Time
  interactive, etc.
• Traffic models of aggregated streams carried by
  Classes of Services are missed, e.g. aggregated
  Multimedia streaming, Real Time interactive
• There is lack of methods and tools for QoE
  (Quality of Experience) assessment for emerging
  applications, e.g. on-line games
• Problems with tools for evaluation signalling
  system
• Limited number of tools, if any (especially tools
  giving insight into signalling process)
• No standard for metrics and methodology for IP
• Call level traffic models should be specified for
  different types of applications (CoSs)

Monitoring and Measurement System in EuQoS (3)

• MMS for supporting EuQoS system functions
• Operation, Administration and Maintenance (OAM)
• on-line monitoring of QoS offered by CoSs
  requires
• a method/tool for on-line measuring of QoS
  parameters between each pair of domain ingress
  and egress points. (scalability!!)
• each point where CAC is performed should be
  loaded up to AC limit -gt supplementary traffic
  generators cooperating with a resource
  reservation system are needed.
• Network Anomaly Detection should be oriented on
  traffic carried inside CoSs
• Connection Admission Control
• Measurements Based AC (MBAC) is aimed to make
  CAC less preventive
• there are some methods for streaming traffic,
  e.g. Hoeffding bounds, methods for elastic
  traffic are also needed
• problems with methods/tools for measuring traffic
  load on high speed links and in short time scale
• call setup proceeding requires information about
  availability of QoS paths (routing). tools for
  routing acquisition are needed (especially
  inter-domain).
• Traffic Engineering and Resource Optimisation
  (TERO)
• traffic matrix estimation for each CoS
• monitoring of overprovisioning ?
