The world is getting flatter and flatter, hierarchies and structures leave way to way to mesh and mash ups. Value chains morphs into ecosystems. The impact on the biz is significant. What are the new challenges that the management of networks and services have to meet?

In addition, ecosystems tend to have a much more dynamic sense of stability, their evolution is subtle in the short term but can be staggering in the longer term. And as they evolve they may overlap and this leads to dramatic changes in the way biz and supporting infrastructures are shaped. Words like pervasive and ubiquitous may assume a quite different connotation: no more something planned and directed from the center to the edges under the control of few actors, rather something happening as result of loosely related actions originating at the edges.

The talk will address the broad picture to stimulate thinking on the direction for the next steps, both in fixed and mobile infrastructures as well as in the changing paradigm of service creation and provisioning.

Today’s wireless networks are characterized by a fixed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15% to 85% with a high variance in time. The limited available spectrum and the inefficiency in the spectrum usage necessitate a new communication paradigm to exploit the existing wireless spectrum opportunistically. This new networking paradigm is referred to as cognitive radio networks. In this talk, the novel functionalities and current research challenges of the cognitive radio networks are explained in detail. More specifically, an overview of the cognitive radio technology is provided and the network architecture is introduced. Moreover, the cognitive network functions such as spectrum management, spectrum mobility and spectrum sharing are explained in detail. The influence of these functions on the performance of the upper layer protocols such as routing and transport are investigated. Moreover, the network management, operation and maintenance problems are highlighted and open research issues in these areas are also outlined.

Characterization of Internet traffic has become over the past few years one of the major challenging issues in telecommunication networks. It relies on an in-depth understanding of the composition and the dynamics of Internet traffic, which is essential in management and supervision of the ISP’s network. Furthermore, the increased capacity and availability provided by broadband connections has led to a more complex behavior for a typical user, very different from a dial-up user. In general, characterization of Internet traffic from users plays a key role in capacity planning for the infrastructure needed for matching users demand and in proposing new management policies and even personalized pricing structures. There have been some recent efforts on measuring and analyzing Internet traffic. Most of them point out that currently the predominant type of traffic is produced by peer-to-peer (P2P) file sharing applications, which can be responsible for up to 80% of the total traffic volume. In more recent analyses, last year’s Video traffic has greatly increased Internet usage, surpassing P2P. Furthermore, the current trend of moving phone calls from the PSTN to the Internet via P2P VoIP applications represents a threat to telephony companies and its effects have not yet been completely understood. However, those previous investigations suffer from known limitations, such as lack of scalability (e.g. in packet-based analysis), loss of information due to traffic summarizations (e.g. in MIB/SNMP byte count analysis), failure to correctly identify the application (e.g., when relying only on protocol types and port numbers) and little comprehension of the user behavior. Most work in this area in recent years focus on scalable traffic identification, based on inference methods (heuristics, information theory, clustering, machine learning, etc) using flow or even packet header information, yet relying on packet payload (signature) for benchmark. The latter has some drawbacks that hinder it to be used as an effective application identification method, such as limited scalability, encrypted traffic and privacy. As the Internet continuously grows in size and complexity, the need of comprehensive understanding of the underlying network traffic becomes evident. There are several benefits of having an in-depth knowledge of the network traffic, such as network capacity planning, traffic engineering, fault diagnosis, application and protocol performance profiling and anomaly detection. However, conducting a sound Internet measurement and analysis study is a difficult undertaking.

TUTORIAL 1 - Autonomic Networking: Theory and Practice
Monday, April 7th 2008 - 9:00-12:30

Instructor: John Strassner

This tutorial provides an in-depth review of how autonomic networking, and features the use of several demos to illustrate the points. Autonomic technologies are used to both manage the increasing business, system, and technical complexity of computing systems as well as to provide a number of important business and technical benefits. These include the automation of functions as well as enabling business needs to drive the services and resources available from the network. This tutorial uses a novel autonomic architecture, called FOCALE, to illustrate the complexities in managing wired and wireless networks, and provides the tutorial participant with a relatively deep understanding of the source of these problems and a variety of tools that can be used to solve these problems. The tools examined by this tutorial include: (1) the use of information modeling to harmonize and translate between the different languages and management methods used by different devices; (2) a different approach to the existing autonomic control loops used in order to meet the more difficult demands of autonomic network management, (3) the use of a novel context-aware policy management approach to enable the services and resources of a network to change in order to meet the demands of changes in current environments, user needs and environmental conditions, (4) how to represent different semantics associated with network configuration and service demands, (5) how to orchestrate the behavior of network services, and (6) the use of machine based learning and reasoning to achieve service orchestration more effectively and efficiently. The theoretical lessons in this tutorial will be reinforced with use cases and practical examples, including a demonstration of ongoing research work in Motorola Labs.

This tutorial is relevant to both telecommunications and enterprise service management. This tutorial builds on the theme of this year’s NOMS conference, which is Pervasive Management for Ubiquitous Networks and Services. Specific use cases covered in the tutorial include tools for managing and providing a pervasive presence, peer-to-peer applications and services, dynamic network organization and control, Seamless Mobility, and, most importantly, how to provide invisible management. Benefits include understanding of the latest state-of-the-art mechanisms in network and service management, an understanding of how to move systems and devices towards increased self-awareness and self-manageability, and how future demands of next generation networks and services can be met.

TUTORIAL 2 - Internet Routing Management
Monday, April 7th 2008 - 9:00-12:30

Instructor: Deep Medhi

Routing in the Internet in its simplest form plays the role of carrying information between two end devices. Due to the structure of the Internet being federated, many components need to play together to make routing between two end devices work, and more importantly, make it work efficiently; in this regard, management plays a critical role in a federated environment. In addition, the federated environment leads to peering and tiering arrangements, and so on. In this tutorial, I'll present an overview of Internet routing, along with several critical management components such as intra/inter-domain traffic engineering, IP prefix management, and policy management. The main focus is on routing management, rather than routing itself. However, the basics of Internet routing architecture will be discussed at the beginning so that the audience get the most out of this tutorial.

TUTORIAL 5 - Designing, Optimizing, and Evaluating Network Security Configuration
Friday, April 11th 2008 - 9:00-12:30

Instructor: Ehab Al-Shaer

The importance of network security has been significantly increasing in the past few years. However, the increasing complexity of managing security polices particularly in enterprise networks poses real challenge for efficient security solutions. Network security devices such as Firewalls, IPSec gateways, Intrusion Detection and Prevention Systems, as well as end-host access control servers operate based on locally configured policies. Yet these policies are not necessarily independent as they interact with each other to form global end-to-end security. Managing these security policies are complex and error prone. Intra- and inter-policy conflicts or inconsistency is one of the main challenges for deploying effective security. In addition, the complexity of changing, testing and validating security configuration in real-time environment become a major hindrance for evaluating security. Furthermore, security configurations such as policy rules are mostly defined in low level abstraction and represented in isolation of each other, which makes reasoning and discovering configuration anomalies intractable.  As a result, the complexity of integrated security management not only makes modifying and enhancing policies a nightmare for administrators, but it also increases the risk of network and end-system vulnerability to serious security breaches. Last but not least, there is a need for automatic distribution of filtering polices to achieve a balance between quality protection and performance.

This tutorial is divided into four main parts. In the first part, we will present techniques to verify and correct firewall and IPSec/VPN polices in large-scale enterprise networks. In the second part, we will discuss techniques to optimize and distributed the filtering policies in order to improve both security and performance.
