  1. «Techno-economics for next generation fixed access networks » � Methodology and framework – some key assumptions; � Major results of the fixed broadband access evolution scenarios Author: Thomas Monath, T-Systems Enterprise Services GmbH Co-Author’s: Sandro Krauss, Mario Kind, T-Systems Enterprise Services; Chris Hawinkel, Jan Van den Abeele, Alcatel; Antonio Elizondo, TID; Antoine Chuquet, Yann Denis, FT; Damiano Raspollini, TI; Daniel Ågren, Acreo; José Miguel Santos, Ricardo Afonso, PTI; Panagiotis Saltsidis, Thomas Kallstenius, Ericsson;

  2. Outline � MUSE “Gaming field” � Objectives & Research Questions of MUSE techno-economics � Methodology & Framework Assumptions � Use Case Definitions and major Results � Migration use cases � Native Ethernet cases � Main Conclusion of the fixed broadband access evolution scenarios 2

  3. MUSE “Gaming field” - Network evolution towards NG multi service capability Multi-service capable NGN leads to requirements: > Platform functions converge > Service & Network platform elements require new functions to be implemented (NT … aggregation nodes … BRAS ) > Bottleneck in the last mile must be overcome Automated OAM Application Application Subscriber, QoS, Subscriber, QoS, Lower cost server server and OAM management and OAM management Edge Edge node node Internet Internet FTTH FTTH Fixed-mobile convergence Access Access multiplexer multiplexer PSTN PSTN Increased intelligence New multimedia in access applications Access Aggregation Access Aggregation Network Network Wireless feeder Wireless feeder High bandwidth Home Home Increased fibre penetration New revenues by gateways gateways “Multi-service” access Application Application DSL DSL servers servers Functionality moving Applications initiated Kerb/Cabinet Kerb/Cabinet closer to subscribers from various CP devices 3

  4. Objective & Research Questions Provide techno-economic validations of MUSE architectural and functional choices: > Two major technology trends in NG Access and Aggregation using Ethernet transport technology between home gateway and service edge in order to provide IP based services: > Pure Ethernet based switching technology (IEEE 802.1 xx) based on MAC in combination with service (S)VLAN “pipes” and > “IP” based network architecture using IP forwarding functionality based on the IP packet source and destination information > Functional evolutions: > PPP � DHCP, QoS, Multicast Approach: > Investigate several network migration and “Greenfield” scenarios (actually focused on Network Access Provider) 4

Methodology – Cash Flow Analysis Demand for the Telecommunications Services Tool - Geometric Services Architectures environment DB Model OA&M Revenues Investments Costs Cash flows, Economic Profit & loss accounts Inputs Year 0 Year 1 Year n . . .

  7. General Assumptions > Case study approach with focus on Access & Aggregation Network > Study period 2005 – 2010 > Business Model seeds back a certain percentage of the revenues to all players (NAP share is considered only, 100% market share applied) > Discount Ratio equals to 10% for all scenarios > Network elements in general will be modelled based on publicly available price information combined with learning curves & maintenance costs assumptions > OA cost model considers: • Network Operations incl. Management, Control,.. • Employees depending expenditures • Provisioning costs • Sales and Marketing 7
