Tutorial-A:
"IP traffic measurements: technologies, tools, and protocols "
Wednesday, October 1,
2003: 2:00 pm - 5:00 PM
Speaker: Maurizio Molina,
NEC Europe
Outline:
Traffic Measurement in the Internet,
particularly traffic flow measurement, is an area of rapid growth in
recent years, although the issue is not new at all. But many tools have
been developed and methodology and technologies have been improved.
The tutorial first gives an overview
of the applications needing IP traffic measurements, listing their requirements.
Then, an overview and classification
of the several existing measurement techniques is presented, and the
generic traffic measurement process is introduced. The challenges of
capturing IP packets at link layer level and at network level are discussed.
For traffic metering, there exist
several IETF standards (RTFM, IPPM, RMON, IPFIX, PSAMP) and other de-facto
standards (e.g. NetFlow). The tutorial gives and overview of these as
well as of common low-level metering tools.
On higher levels of IP traffic
measurement, a large variety of tools, frameworks, and systems can be
found supporting graphical display of measured flow data, integration
and correlation of measurements from different locations, and integration
with applications such as traffic engineering and accounting. A
representative subset of these is presented.
Finally, an outlook is given including
recent developments, current activities and challenges ahead. In particular,
it is presented the new concept of passive measurements for performance
estimation, that enables some interesting applications (trajectory discovery,
One way delay estimation) that are difficult or unfeasible to achieve
with active measurements.
Speaker's bio: Maurizio Molina received his electronic engineering
degree in 1993 from the Polytechnic of Turin, Italy. From 1994 to 2000
he worked in the Network Planning and Traffic Engineering department
of Telecom Italia's R&D center (TILAB, formerly CSELT), where he
participated in the design and evaluation of systems for the measurements,
dimensioning and traffic control of IP, ATM and Telephony networks.
He contributed to the ITU-T standards for ATM Networks and published
papers in the area of IP and WEB traffic modelling. From March 2000
to May 2001 he worked at Flextel, an Italian IT and Network equipment
start up company. In June 2001 he joined the NEC Network laboratories
Europe (in Heidelberg, Germany) where he's currently working in the
area of Traffic Measurement and Monitoring. He's a co-author of a draft
in the
IETF PSAMP WG on packet sampling techniques, and contributed to the
design and implementation of an IPFIX compliant traffic flow meter.

Tutorial-C:
"Mobile All IP network Service Architecture Options"
Friday, October
3, 2003: 2:00 pm - 5:00 pm
Speaker: Thomas Magedanz, Fraunhofer Institute FOKUS, Germany
Outline
This tutorial provides for managers,
marketing staff, and decision makers a high level overview and comparison
of the available architecture options within the emerging Wireless 3G
market. As such the seminar introduces the evolution form today's 2G
systems to the overall 3GPP architecture (CS. PS, IMS) and subsequently
looks in some detail at the IMS architecture options. These are
mainly the - 3GPP Customized Applications for Mobile enhanced Logic
(CAMEL) and the related American Wireless Intelligent Network (WIN),
- the emerging open network Application Programming Interfaces (APIs)
from 3GPP (OSA), Parlay and the Java APIs for integrated Networks (JAIN),
and - the all IP networks based on the Session Initiation Protocol (SIP)
and related protocols. The seminar introduces and compares these architectures
and also looks
at potential synergies and migration paths from existing architectures.
1. Overview of 3G Services and
Architecture - Next generation mobile networks, business models and
expected services - Migration from today to all IP networks - The 3GPP
3G
Architecture: CS Domain, PS Domain, IMS Domain
2. SIP Basics and SIP AS - VoIP
Basics (Signaling vs. Bearer Transport) - Basic SIP architecture and
operation - SIP Services and VAS provision
3. 3GPP CAMEL, WIN - The foundation:
Intelligent Network Basics - CAMEL Architecture and Services (Prepaid
Roaming, VPN, etc.) - CAMEL evolution (Phases) - CAMEL vs. WIN
4. 3GPP OSA / Parlay / JAIN -
The foundation: IT Basics (CORBA, Java, Web services) - API principles

Tutorial-D:
"Networks Have To Think Smarter: An IP vision on distributed FCAPS
functionality"
Friday, October 3, 2003: 2:00
pm - 5:00 pm
Speaker: Petre Dini, Cisco Systems, Inc.
Outline:
The tutorial presents challenging
management issues in increasingly-becoming-smart IP networks. Its journey
goes from FCAPS diagnosis functionality inside network devices to complement
IP-family protocol-based information, and ends with the most recent
ITU and IETF documents on related subjects. The first part introduces
what is perceived as missing in the current networks to provide more
self-functionality, from both device perspective and interaction perspective.
The presentation identifies how distributed FCAPS can be melt into networks
and what monitoring procedures are in place to support the paradigm.
Particular mechanisms combining Syslog and SNMP IP-oriented information
which
complement the routing protocols' updating functions (OSPF, BGP, etc.)
are scrutinized. A particular insight is given to separation of concerns
of what is needed in IP networks from the FCAPS perspective to satisfy
wish-to-be functions related to preventive, proactive and reactive manageability,
as well as to discovery, isolation, and restoration functions in terms
inside-IP-networks,
and inside-FCAPS-managing-applications. Status on different ongoing
standards and working groups activities is also presented.
