In 2003 through an RFP UNET was selected as the operator/ service provider for pilot optical fiber services in the City of Almere, the Netherlands; services started in March 2004.– City of Almere, e-city
• 180,000 people• Fastest growing city in NL• 250 km2 reclaimed land,
– UNET, broadband innovator• Founded 2003 • Privately funded• 35 employees• profitable

In Almere public/private partnership combines both community development and commercial interests, including competition:– City of Almere
• Economical development • Open ICT infrastructure• Increased social cohesion• BB expertise center in NL
– UNET • Service broker role• Managed services• Managed shared network• New service development
Goals and strategies

In the Almere Fiber Pilot we required technical solutions that were future-proof, scalable and at the same time using proven technology.– Passive Network
• Future proof, Secure, Low Management Costs– Active network
• Manageable, Scalable, Affordable– Service Center
• Automated Customer and Management Processes– Multiple Broadband Services
• Open, Extendable, Automatically Provisioned
Requirements

The strategy is to focus on one shared open infrastructure and to create an abundance of content and services:– FttH infrastructure has to be simple, and future proof
• Star based SM fiber network• IP/Ethernet 100 Mb/s and 1000 Mb/s• VLAN separated services• Separate network and service
management– UNET’s Open services model
• Service broker role• Managed services, wholesale vs. retail• Highly automated provisioning and
customer care• Customer orientation
Deployment Strategy

Almere selected UNET based on it’s service offering, aligning with Almere’s notion that fully digital triple-play is a basic requirement and just the starting point for further services:– UNET Triple Play
• 10 Mb/s symm internet • 75 digital TV, 20 radio• VoIP• Web page, community portal, data vault
– UNET additional services (2005)• Managed VPN• Remote backup• LAN connectivity• Hosting, etc.

The passive network needs to be low maintenance and future proof, design decisions:– Star Architecture into the building– Minimize Active fiber Sites– Single Mode fiber– Single homes/buildings fiber connected– Multi-dwelling internal cabling in UTP Cat

– Optical fiber is cheap, reliable and long-lasting

Design characteristics: – Service Separation– Digital Convergence– High Bandwidth– Redundant Routing
Design decisions:– IP/Ethernet– 100 Mb/s homes/SME’s, 1 Gb/s
Business– VLAN separation– L3 & L2 Services

The customer connection is future proof and easily maintained and upgraded: – Auto-installation– 100 Mb/s to 1 Gb/s upgrade path– Fully Managed and Monitored– Automatic Firmware Upgrading– Full Control over Services
Important:– The Residential Gateway
firmware delivers the content– Don’t cut corners here

IP radio/TV content
Service Characteristics– MPEG-2 over IP Multicast– 80 Channel TV Package
• Dutch: 11 Channels• Local: 6• International: 21• News: 6• Sports: 5• Nature/Science: 8• Music: 13• Entertainment: 10
– 20 Channel radio package

IP TV architecture
IP TV
Mediaplayer connects toTV set with SCART cable
The mediaplayer (STB) is controlledby the TV server. The player does amultcast join for a TV channel
The C/O switches blockthe multicast streams
The video streamer delivers: - 80 TV channels - 20 radio channels - MPEG2 multicast streams of 3 - 14 Mb/s
C/O switch
Residential gateway
Only the selected multicaststream will be forwarded

IP TV delivery
Settop boxes are currently the only way to connect a TV set in Ethernet
• UNET uses 3 brands– Telsey– I3Micro– Amino
• Settop box characteristics– Memory size– Decoding Algorithms– OS: WIN CE vs Linux– MPEG-2 or 4– Other features

IP TV quality
Quality Characteristics– BW: uncompressed PAL 270 Mb/s– MPEG-2 VBR: 3 – 14 Mb/s– MPEG-2 CBR: 5 Mb/s– 80 channels feed requires ±400
Mb/s– Picture quality, VBR vs CBR
– Buffering vs zap time

IP transport
IP transport quality issues need to be addressed in the network design phase:– TCP or UDP– Unicast or Multicast– Latency, jitter and packet-loss– Quality of Service– VLAN for services– Design for IPTV

Future of IPTV
At UNET we are working to add exciting new dimensions to the TV and our unlimited bandwidth makes that feasible:– 2005 HD TV with surround sound (1080p and
5.1)– 2005 VOD– 2006 Interactive channels– 3D TV

Lesson Learned
IP TV is feasible– A stable service has been accomplished– Lot’s of channels, and beyond the
satellite there is more– High quality picture and sound– Low overhead
Never forget– Make the right choice of Set top box
supplier– It is all software – Design your network for IP TV– Be prepared and plan for the
unexpected!
