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

•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

Protocols
•Monitoring and Measurement System
(MMS) that support EuQoS system
functions: CAC, TERO, OAM

Monitoring and Measurement
System in EuQoS (1)
MMS includes tools for:


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
•
to perform Network Anomaly Detection

 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)

 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 -> 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 ?
