Multi Service AccessSecure Connectivity
Ethernet assumes a trusted LAN environment
• Ethernet MAC@ can be configured by user
– Spoofing, conflicts
• Broadcast of some initialisation messages (ARP, DHCP, PPPoE)
– DOS attacks– Confidential info to users or
competing providers
Secure connectivity approaches
• Anti-spoofing tables
• Model 1 (L2)– Cross-ConnectVLAN – Bridging Ethernet MAC@
• Model 2 (L3)– IPv4/IPv6 forwarding

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
=> Simplified QoS control in Access & Aggregation needed

NRC
Network Resource Controller (NRC)• View of flows and BW already allocated
• Configures policers at borders
• Admission control after request

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

Summary
From Tripleplay to Multiplay• MM BB convergence: 1+1+1 = 7 !• Fixed mobile convergence
Building a Multi Service Access with Ethernet• L2 or L3 forwarding model• QoS guarantees by network resource control
Increasing the capabilities of the access platform• Embedding service enablers• Making the fixed access network ready
for nomadic services and session continuity
Increasing the bandwidth capacity in the first mile at lower cost
