• Different L3 Edge by service, services can be added and managed independently
• SP Edge physically could be one L3 box, but likely is many
• Supports Geographic segmentation of application servers
• Allows the use of distributing IP on a per service basis (e.g. multicast!), rather than
using L2
• Services needing per subscriber policies (internet, peer2peer, Lawful Intercept)
inserted centrally, while ‘simpler’ services (IPTV, VoD) are distributed
• Allows services & transport to be reused across a variety of access technologies
• Intermediate tunneling technologies transparent to the CE .
