Broadband VPNs - Outsourcing ISP Services to Cable TV and xDSL Providers Bruce Perlmutter Bay Networks Corporate Systems Engineering
IPsec • IP Security, derived from IPv6 • Packets can have AH (Authentication Header) and ESP (Encapsulating Security Payload) • AH authenticates each packet - data integrity • ESP provides privacy - DES (56-bit) or Triple DES (112-bit) • Tunnel mode provides private addressing and doesn’t require IPsec between end nodes
PPTP • Point-to-Point Tunneling Protocol • Developed by Microsoft • Uses 40 or 128-bit RC4 encryption • Well integrated into Windows 95 and NT • Well integrated into NT Domains • 3rd party implementations available
Win-Win-Win • End Users • High Speed Internet Access • Service Selection • Quality through Competition • ISP • New Subscriber base without large Infrastructure investment or management • Works with all xDSL and Cable modem architectures • Network Access provider • New Revenue source without understanding ISP business • Standards based VPN solution with a future • Simple provisioning and management requirements.
