  1. NOBEL WP2 MeetingActivity A.2.2 Krzysztof Wajda, Krzysztof Zaraska AGH – UST, Department of Telecommunications e-mail: wajda@kt.agh.edu.pl,kzaraska@uci.agh.edu.pl

  2. WP2: Survivability, traffic engineering, techno- and socio-economic studies and evaluations AGH University of Science and Technology • A2.1 - Investigation of advanced survivability concepts for multi-service / multi-layer / multi-domain networks • A2.2 - Study of traffic engineering concepts for end-to-end broadband services for all • A2.3 - Techno-economic analysis of network solutions and evaluation of their economic viability • A2.4 - Socio-economic feasibility studies for investigating and assessing new social and economic opportunities • A2.5 - Definition and assessment of different business models for the solutions proposed by NOBEL

  3. WP2 - A2.2: Study of traffic engineering concepts for end-to-end broadband services for all Activity objectives: • Measurement, characterization and modelling • Solutions to optimise utilisation of network resources • New methods for route management (intra- and inter-domain) • Develop accurate statistical models for evaluating the impact on QoS AGH University of Science and Technology

  4. WP2 - A2.2 – AGH Task 1:Traffic measurement and modellingMeasurement platform • LAN of DoT AGH includes about 200 PCs and servers split into 2 subnets (staff and student) – 149.156.114.x • Uplink to the campus done previously by ATM, now by GigaEthernet • Monitoring/measurement of traffic done thanks to uplink interface mirroring C2924XL-EN C2948G-L3 PIX Cisco 36xx FEC Ethernet 100 Ethernet 100 Campus Network ATM FEC FEC Mirrored link Mirroring link Monitored hosts Measurement PC AGH University of Science and Technology mirrored link

  5. WP2 - A2.2 – AGH Task 1:Traffic measurement and modellingCaptured information ·Timestamp (instant of frame end in microsec), ·Ethernet frame type and length, ·IP protocol version (IPv4 or IPv6), ·IPv4 source and destination addresses, ·Layer 4 protocol (i.e. TCP, UDP, ICMP), ·Layer 4 port numbers (for TCP and UDP traffic), ·TCP sequence numbers (for TCP traffic). AGH University of Science and Technology

  6. WP2 - A2.2 – AGH Task 1:Traffic measurement and modellingMeasurement plans • Searching statistical properties of total traffic, • Characterization of frequently used service types, such as http, ftp, telnet, etc., • Testing the selfsimilarity of traffic (estimation of Hurst parameter), • Testing traffic symmetry (uplink/downlink), • Evolution of the traffic properties over time, e.g. daily variations, and seasonal trends. AGH University of Science and Technology

  12. WP2 - A2.2 – AGH Task 1:Traffic measurement and modellingFurther plans • Searching statistical properties of total traffic, • On-line estimation of Hurst parameter, • Analysis of service profiles (amount of traffic sent), session/connection charasteristics, • Analysis of traffic geographical distribution.
