Abstract: T7

Global competition, the immense increase of packet traffic, and the introduction of interactive broadband services force network operators to adapt and optimize their transport network. The technological convergence and the evolution of circuit switched transport networks towards a common packet-based transport technology will change the way all types of traffic are being carried through the network. The total cost of ownership will be decreased through the introduction of new optimized network architectures while revenues will be increased by the introduction of new high-value services such as TV broadcast and video services.
Right from the start, Ethernet technology has been a success story in local and metro networks. In the last few years it has become synonymous with simple, self-configurable, and cost-effective networks. It is within this framework that Ethernet is also becoming a feasible option to enable future transport networks. However, classical Ethernet technology lacks a number of characteristics that are required for transport networks. Therefore, a number of new Carrier Ethernet architectures and technologies are currently discussed in research and standardization. While some of the concepts rely on known Multi-Protocol Label Switching (MPLS) concepts like L2-MPLS and Transport MPLS (T-MPLS), two others, namely Provider Backbone Bridging – Traffic Engineering (PBB-TE) and Virtual LAN Cross-Connect (VLAN-XC) use connection-oriented methods based on Ethernet to establish tunnels. This tutorial gives an in-depth overview of transport requirements and discusses evolving Layer-2 technologies and architectures that provide the demanded flexibility, predictability, and carrier-grade quality for future connection-oriented packet transport networks.

Abstract: T8

Emerging Internet Quality of Service (QoS) mechanisms are expected to enable wide spread use of real time services such as VoIP and videoconferencing. The "best effort" Internet delivery cannot be used for the new multimedia applications. New technologies and new standards are necessary to offer Quality of Service (QoS) for these multimedia applications. Therefore new communication architectures integrate mechanisms allowing guaranteed QoS services as well as high rate communications.
The service level agreement with a mobile Internet user is hard to satisfy, since there may not be enough resources available in some parts of the network the mobile user is moving into. The emerging Internet QoS architectures, differentiated services and integrated services, do not consider user mobility. QoS mechanisms enforce a differentiated sharing of bandwidth among services and users. Thus, there must be mechanisms available to identify traffic flows with different QoS parameters, and to make it possible to charge the users based on requested quality. The integration of fixed and mobile wireless access into IP networks presents a cost effective and efficient way to provide seamless end-to-end connectivity and ubiquitous access in a market where the demand for mobile Internet services has grown rapidly and predicted to generate billions of dollars in revenue.
This tutorial covers to the issues of QoS provisioning in heterogeneous networks and Internet access over future wireless networks as well as ATM, MPLS, DiffServ, IntServ frameworks. It discusses the characteristics of the Internet, mobility and QoS provisioning in wireless and mobile IP networks. This tutorial also covers routing, security, baseline architecture of the inter-networking protocols and end to end traffic management issues.

Abstract: T9

Next generation networks (NGN) introduce a disruption point for telecom operators and represent an additional step in the convergence process that telecom sector is facing in the last years. Are there so many differences in the economics for the new scenario? The tutorial will pinpoint major techno-economic issues that network and service operators are meeting in the current changing scenario, and several simple analysis will be presented in order to acquire an insight in the economics behind NGN.
Topics include an overview of the different levels in the network, access, backhaul & backbone issues as well as questions regarding optimal service provisioning. In each case, main cost drivers to be taken into account when constructing the cost model are presented. In addition, techno-economics behind market and network trends in each of the network stages are discussed:
    • In the access network, next generation access regulation in the European market is reviewed. Difference in economics of wireless and wireline are also outlined.
    • In the backhaul network, it will be discussed whether it should be a level-2 based or a level-3 based network, as well as backhaul convergence with access and/or backbone networks.
    • In the backbone, all optical switching and technologies taking advantage of DWDM as scalable architectures for current demand forecasts are studied.
Finally, a brief discussion on cost models and cost allocation tecniques is given and afterwards NGN cost structure is discussed based on a bottom-up NGN model based on the cost drivers which were appointed in the previous sections. The model is able to plan and calculate the cost for an NGN using a series of parameters such as the line demand, service demand by the users, network topology and cost and performance data for the technologies used to build the network. It will be shown the importance of economies of scale and scope, and a comparison with traditional cost structure of PSTN and data networks. In the end a conclusion including both technical view and economic drivers to NGN will be presented.

Abstract:

After introducing the evolution of carrier networks and the expected role of Ethernet in these environments, this tutorial will analyze the shortcomings of bridged Ethernet when moved into Carrier networks (i.e. the rationale and motivation for the transformation of the intrinsic nature of Ethernet). This tutorial will then provide an in-depth analytical assessment and comparison of the three technological trends in Carrier Ethernet (GELS, PBB-TE, and SPB) and their respective evolutions/paradigm compared to bridged Ethernet (MSTP). As these technologies are still evolving, this tutorial will explain the (known) open research challenges requiring further investigation for Ethernet to fulfill its expectations.

Abstract: T11

The tutorial focuses on providing an overview of the Next Generation Network Architectures and the OAM/OSS architectures developed by ETSI TISPAN in collaboration or based on 3GPP IMS Network Architecture, TISPAN is the ETSI core competence centre for fixed networks and for migration from switched circuit networks to packet-based networks with an architecture that can serve in both to create the Next Generation Network.  Building upon the work already done by 3GPP in creating the SIP-based IMS (IP Multimedia Subsystem), TISPAN and 3GPP are now working together to define a harmonized IMS-centric core for both wireless and wire line networks. This harmonized ALL IP network has the potential to provide a completely new telecom business model for both fixed and mobile network operators. Access independent IMS will be a key enabler for fixed/mobile convergence, reducing network installation and maintenance costs, and allowing new services to be rapidly developed and deployed to satisfy new market demands. NGN Release 1 was launched by TISPAN in December 2005, providing the robust and open standards that industry can use as a reliable basis for the development and implementation of the first generation of NGN systems. TISPAN is now working on Release 2, with a focus on IPTV, enhanced mobility, new services and content delivery with improved security and network management.
In this tutorial, we will details the TISPAN NGN Architecture with all its subsystems, IMS Architecture, the NGN Services, and finally the management (OAM/OSS) architecture and solutions.

Abstract: T12

The telecom market has become very competitive. Technical superiority is definitely not a guarantee for market success. Understanding the market, estimating expected costs and revenues and adjusting accordingly are some additional requirements.
This tutorial aims at giving an overview of the techno-economic planning process of network deployment or migration. All steps are discussed indicating existing models and how they can be applied. We will study the entire flow, starting with a description of the existing situation and the required geographic, demographic, economic and legal information (step 1) and ending with an evaluation of the relevant output parameters such as profitability (step 3). Defining the rollout area – possibly divided in smaller regions – will be the starting point of step 2. A gradual rollout scheme can be used, e.g. starting in high-priority regions and evolving to the rest of the target area. As soon as the rollout scheme is determined, the number of customers for a particular service will be discussed based on different adoption model. Based on the estimations for the adoption, the revenue side will be discussed, consisting of both the calculation of direct (fees paid by customers) and indirect (additional value created for the companyoperator) revenues. A second part of step 2 considers the cost side and will get most attention. We will indicate how capital (capex) and operational expenditures (opex) can be considered jointly in a hierarchical cost modeling view. For process-related costs we will describe an activity-based model with reference to the ITU eTOM model. We will focus on fast cost estimations, given an accurate view based on the available input data. In step 3, different approaches towards techno-economic evaluation will be discussed. We will describe evaluation parameters and show how simulations can be used in order to get a better insight in the impact of the uncertainty on the planning outcome.
