Issues when using Ethernet in Access
Ethernet LAN (trusted environment)
Ethernet in Access (public network)
Bridge learning - Broadcast of some initialisation messages (ARP, DHCP, PPPoE)
• DOS attacks• Confidential info to other users
or competing providers
Secure and scalableconnectivity models
• Model 1 (L2 forwarding)• Model 2 (L3 forwarding)
No authentication AAA
Configurable MAC@• Conflicts, spoofing
Anti-spoofing mechanism
No QoS QoS framework

Multi Service AccessQoS control
QoS is key in multi-service access
End-to-End QoS solutions (e.g. IntServ) • commercially failed because of complexity
Priority based QoS (e.g. Diffserv) • works in Core Networks with sufficient capacity, • not suited for Access & Aggregation
=> Resource admission control in Access & Aggregation needed

Network Service & Applications building blocks
Why Service Rich Access
Why in Access Platforms?
Ingress/Egress of the network (Monitoring, Security)
Unique user centric view on the traffic (Personalization)
Bandwidth in Access more suited for deep packet processing capabilities (Scalability)

Time Shifted TV
Time Shifted TV: watch broadcast programme with delay
Today: TSTV = VoD from central server or CDN server located at the edge of the network
• Multiple retransmissions => risk of congestion for large deployments.
Idea: Distribute caches and streamers in the aggregation nodes
