Title: IP Impact on the Evolution of Telecom Networks
The
tutorial examines the issues facing service providers in evolving their
networks
to
offer IP-based services while maintaining their competitiveness. It describes
what
needs
to be managed, both from a network and service perspective, and the
challenges
facing the industry to provide the appropriate management solutions.
Several
management paradigms have been developed, and are being deployed with
different
degrees of maturity. From an IP-based networks and services perspective,
management
solutions are still at the conceptual state, and more work is needed.
Another
important aspect is the need to build the business case for management
solutions
to accelerate their adoption and implementation. In addition, the smooth
evolution
from the current multi-domain environment to an integrated end-to-end
management
infrastructure, while preserving the current investment in network and
operations
management systems, is required. The opportunities and challenges in
achieving
a unified view in managing the resulted environment will be discussed.

Title: Quality of Service for real time service in Data Networks
The Internet
is based on the TCP/IP protocol that does not provide Quality of Service
(QOS)
guarantees to real time applications such as multimedia. The next generation
data networks
are expected to provide QoS to applications to multimedia applications.
Current
efforts to incorporate QoS in the Internet include Integrated Services,
Differentiated
Service, Multiprotocol Label Switching and Asynchronous Transfer
Mode.
Topics to be covered in this tutorial include characteristics of multimedia,
QoS
requirements
for multimedia, Integrated Services, Differentiated Services, QoS
mapping
from Integrated Services to Differentiated Services, ATM in the core of
the
Internet,
Explicit Congestion Notification to reduce loss, and active buffer
management
techniques.

Title : Internet 3 : A smart control and management architecture
Internet 1 (I1) is the first generation: The system that we reach from our terminal today. I2, Internet second generation: We are going to enter there with the year 2000. I3 is arriving and the first concepts are born. I1 comes from the initial work of some tens of scientists in the world believing in a universal system. During the years 1980 to 1990, academic centers exchange messages by the "Net". The period 1990 to 2000 defines the arrival, in the public, of commercial offers allowing to communicate with high-speed servers supporting multimedia services. However, throughput is too slow, servers do not deliver the desired information, browsers surf without end, etc. To the end of the 90s, the promises of increase of the throughput are undeniable, costs become almost accessible, new numerous and attractive service perspectives are clear enough. In the year 2000, I2 arrives with its fantastic throughput, its procession of services, its best stability ahead breakdowns, its quasi universal access. Between 2005 and 2010, the passage to I3 should lead to a more stable system, stabilized protocols, breakdowns imperceptible to the user, a large number of available multimedia applications, a generalized access.
In summary, I2 allows the multimedia for all and wherever. What does it remain to I3? The technological rupture of I3 is hidden, not visible to the final user: The mastery of the complexity of the global network (distributed systems, services, controls and management). Without mastery, I2 will be a system that could collapse under the fulfillment of a virus, the failure of a node or a connection, an electrical problem, the fire within a control center, a malicious application or simply a transient overload. This mastery has "to prevent" but also "to help" users to get the QoS they want. In addition, the distributed nature of the Internet environment implies a very long reaction time. Moreover, the gigantism becomes an important factor, implying a scalable global control.
What directions to push on? The intelligence. The system must be intelligent. The debate on the computer intelligence is not new, but the distributed nature requires for an additional component, the time. The system has to be able to adapt itself to a new situation, to control critical states and to manage unexpected situations. Intelligence is the chosen word to group several actions well distinct: to learn, communicate and infer. Several ways can be envisaged, with their own roots: intelligent networks, smart networks and active networks. Intelligent networks form an already old architectural concept where the word intelligent means adaptation. The system has to be able to adapt to the user demand. Even if some experiences were tested in telecommunication systems, we still are only in the first steps. In this area, the data-processing could induce a too large delay when using languages like Java, that disseminate pieces of software in a very large number of points. These pieces of software can possibly move by themselves. Smart networks support the second research area. In this field, it is necessary to develop specific components to bring their expertise to solve problems and to control infrastructures and flows. As a first answer, there are some known solutions coming from the intelligent agents paradigm. An agent is an autonomous entity able to communicate with others agents, to perceive and to represent its environment. The whole agents in interaction forms a multi-agent system. Many criteria allow to classify these systems: The size of agents, the number of agents in interaction, the mechanisms and the types of communication, the behavior, the organization and the representation of the environment.
The third area corresponds to active networks. The intelligence in active networks, situated inside the nodes of the system, as well as in the user workstations, has to adapt the nodes and the workstation to the type of information received. For example, the header of the packets can contain programs that must be executed in the routers. The nodes have to fit instantaneously to the arriving packets. I3 researches focus on the mastery of the global network: I3 will be based on an intelligent platform, distributed allover the network. The basic problem concerns the architecture of the system to be implemented for integrating the "intelligent" components, so that they could be simple and cooperating.
Title : Creating and Managing the Internet that Talks
In the recent months, a new kind of Internet access has started to receive wide attention: Voice. The fast proliferation of wireless phones (expected to reach 1 billion worldwide by the end of 2001) and the intricacies of such devices (small screens, small keyboard, etc) has created a lot of interest around voice-based services. Although voice is perhaps the most natural interface for a human to communicate, there are still significant issues with respect to creating effective user interfaces for general internet access and designing the back-end management infrastructure. This talk highlights this new opportunity, proposes some innovative technical solutions, and speculates on the future importance of such services.

He holds a PhD degree from Columbia University in the area of next generation telecommunication networks and services.
Title: From Private Networks to Universal Computing Utilities
Technology evolution has made it more effective for many companies to outsource most/all of their networking needs. Traditional private networks will eventually disappear - as service providers become capable of providing, at low cost, all the connectivity needs of companies.
New technologies make things possible, they do not make them happen. Economics (cost reductions) and business considerations (increasing sales) is what will actually drive the adoption of new technologies and services.
Many enterprises are outsourcing much of their e-business systems to large server farms that can provide a physical location for the servers with high power, AC, bandwidth, good connectivity, etc.
These hosted customers increasingly require support for peak loads that are orders of magnitude larger than what they experience in their normal steady state, particularly for commercial Web workloads.
The current "collocation" model, however, uses dedicated non-shared infrastructure and servers for each enterprise customer. In this model, enabling peak-load scale on demand requires large investments in standby, non-shared resources, which would be mostly underutilized, and would occupy large amounts of physical space. Such a model has several deficiencies, for instance, it does not efficiently mitigate the differences between average and peak load.
A "computing utility", in contrast, is built upon an infrastructure that leverages massively parallel servers interconnected by switched LANs to provide seamless scalability.
This talk will describe some of the challenges involved in effectively outsourcing the aforementioned assets and resources, and will suggest some possible ways in which computing utilities will address them.
