From triple play to multiplay

From Ethernet to Multi Service Access

First mile: higher BW at lower cost

Summary


MUSE Overall Objective

Multi service access network that provides secure connectivity between end-user terminals and edge in a multi-provider environment at a low cost for every European citizen.

The AmigoTV Experience: Watching Television Together

> Find your friends on TV

• Use ‘Channel presence’ to find out what they are watching

> Talk with your friends• Comment on the TV

program

> Share your emotions• Change the expression

messages

Community Television, the next step for Interactive TV= Communication between TV viewers

(*) Avatar = your graphical presence on TV

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

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
