1 Next-Generation Subscriber Access Methods Presenter: Donnovan Wint Technical Marketing Manager Lucent Technologies

2 Slide 2 Access providers need to plan and prepare now to support the new infrastructure that will be required to offer these high-speed services. Key Growth Segments

3 Slide 3 uU.S. Market –Subscriber base with access cable - 25 million –5% use service today (non DOCSIS based) –10% by end of 2001 (DOCSIS based) –Subscriber base with access xDSL - 20 million –5% use service today –7% - 10% by end of 2001 uTarget IP Addresses (Cable/DSL/ISP) worldwide –Year Million –Year Million Source: Network World Automating the subscriber registration process and configuration of related broadband access devices is essential to the success of service providers. Broadband Opportunity

4 Slide 4 Service Provider Network DSL FTTH (Fiber to the Home) Cable Wireless Broadband Access Options

5 Slide 5 Remote Client DHCP/PPP RADIUS Corporate or Internet Resources RAS 2. Dial-out 3. Handshake 4. Authentication 5. IP address negotiation 6. Access to resources 1 Internet or Intranet SnailSpeed - Dial Up Approach 1. Modem connection

6 Slide 6 uRequire no truck roll, that is: Require no re-configuration by the user of IP stack information. Require no configuration of broadband access device at the customer site. uUse industry-standard, low-cost Ethernet NICs to connect users PC to broadband access device. uLeverage proven, existing technologies if need be … (Web, TFTP, etc.) What is Required to Be Successful

7 Slide 7 uStatic IP Addressing uPoint-to-Point over ATM (PPPoA) uPoint-to-Point over Ethernet (PPPoE) uDynamic Host Configuration Protocol (DHCP) Broadband Architecture Options

8 Slide 8 uMost straightforward broadband IP configuration option uRequires re-configuration by the user of IP stack information uRequires configuration of broadband access device at the customer site uLeast flexible broadband IP configuration option uNetwork modifications are difficult to implement uMost costly in the end to implement and maintain Static IP Addressing Architecture Option

9 Slide 9 uPPP can be run over either an ATM (PPPoA) or an Ethernet (PPPoE) infrastructure. uRequires re-configuration by the user of IP stack information uRequires configuration of Broadband Access Device at the customer site uDoes not work with cable modems uCan be COSTLY in the long run to implement and maintain PPP Architecture Option

10 Slide 10 IP PPP L2TP PPP ATM IP PPPoA PPP PPPoAL2TP ATM ATM VC, IP Tunnel,etc. NSP/ISP PC Service Gateway ATU-R (DSL Modem, etc.) ATM PPPoA Architecture Issues

11 Slide 11 IP PPP L2TP PPP Ethernet ATM IP PPPoE PPP PPPoEL2TP Ethernet ATM 10-BT Ethernet ATM VC, IP Tunnel,etc. NSP/ISP PC Service Gateway ATU-R (DSL Modem, etc.) PPPoE Architecture Issues

12 Slide 12 NSP/ISP Cable/DSL/ Broadband Access Server PC Hub Consumers are accustomed to accessing the Internet through a fairly inexpensive modem requiring minimal configuration. PPPoE Approach

13 Slide 13 Re-configuration by the user of IP stack information is required. The user installs the PPPoE drivers Typical PPP/PPPoE

14 Slide 14 uDoes not require ANY re-configuration by the user of IP stack uBuilds on the open system philosophy uEngineered from bottom-up, not a forced fit implementation uCentralized management; distributed functionality DHCP Architecture Option

15 Slide 15 DHCP Solution Components DHCP Approach

16 Slide 16 Simple process Customizable screens Ability to leverage user-defined and customized authentication methods Leverages existing and proven technologies…(Web, DNS, TFTP, etc.) Typical DHCP Authentication

17 Slide 17 Select desired service Service selected is stored in the directory server Can implement callout to notify OSS system of selection Selections are pre-defined Typical DHCP Service Selection

18 Slide 18 C:\> ipconfig Windows NT IP Configuration Host Name : donwint-nt.lucent.com DNS Servers : Node Type : Hybrid NetBIOS Scope ID : IP Routing Enabled. ….... : No WINS Proxy Enabled..... : No NetBIOS Resolution Uses DNS : Yes Ethernet adapter El9201: Description : 3Com EtherLink PCI Physical Address : 00-B0-D F8 DHCP Enabled : Yes IP Address : Subnet Mask : Default Gateway : DHCP Server : NO re-configuration of IP stack information is required by the user. Simple No new command to learn Typical DHCP

19 Slide 19 How Do They Compare

20 Slide 20 uNext-generation broadband access will provide huge business and growth opportunities for those who are properly prepared. Access providers need to plan and prepare now to support the new infrastructure that will be required to offer these high-speed services. uAlways on high-speed Internet access, enhanced on-line gaming, personal videoconferencing, on-line shopping and banking, VPN telecommuting, and entertainment-on-demand services all require configuration of the access device and the end-user PCs in a way that is standards-based, vendor- independent, and reliable. uIn preparing for tomorrows networks, providers need to consider several criteria when selecting a next-generation architecture, including implementing a standards-based solution, vendor interoperability, carrier-class reliability, true scalability, and manageability.
