With voice growing at 8%, in 5-10 years, voice will be a small minority of network bandwidth. The optimal strategy for the future may be to handle voice as much as possible like data.

What is a Next-Generation Network?
Single Integrated Pipe
Video
High-SpeedData
Voice/Fax
Services
“A network where all kinds of information (voice, fax, video, data) are transported uniformly using packet-based transport and switching media.”
“A network where all kinds of information (voice, fax, video, data) are transported uniformly using packet-based transport and switching media.”
HFC (Cable) Network using DOCSIS transportATM or IP Over xDSL Lines

NGN Solutions v7 – 7
Why a Next-Generation-Network?
Using IP, operators can create an integrated multi-service communications platform– Lower cost structure than competing switched alternatives
which enables aggressive price discounting without sacrificing margins
Flexibility of IP networking allows delivery of value added features– Real-time provisioning of additional lines– Integrated voice mail, data services, etc.
Enables bundling with existing service offerings NGNs and the PSTN will co-exist for years, making true
interoperability essential

NGN Solutions v7 – 10
Next Generation Network - Traditional and New Services
Traditional Services• Two to Four POTS Lines• Fast Internet Access• On-Net Long Distance• Advertising
Work At Home• Virtual Circuits for Phone and PC• Professionals• Distributed Call Center Applications
The Long-Term Vision: A Programmable Network with a
Software Developers Tool Kit to buildLots of New Integrated Voice/Data Services
Traditional Services Pay for the Network,New Services Fuel the Growth!
Internet Voice Applications• Click to Talk• Internet Call Waiting• Wireless Data• PC Call Center with Voice / Internet• “Rent an App” (e.g., PC Blackboard)
Dial Tone II• Java Ring Contains Your Identity• “Instant” Access to Email and WWW• Always On; No Wait!
NGN Solutions v7 – 11
Traditional Telephony
Typical call - – user dials number– trigger in switch specifies if look-up (translation) is needed
(600, LNP)– Query sent to centralized database
Centralized servers (Intelligence) (~45 servers)– Providers share cost….share ownership– Each server configured for masimum of 1500 reads/sec– Updates mostly from centralized management system
Dumb endpoints (Telephones) Intelligent Endpoints
– Switches (difficult to program) New services introduced by trusted providers
NGN Solutions v7 – 12
NGN
Multiple numbering systems – IP, Phone, Universal Numbers
Distributed Intelligence– Databases in central servers, Provider database, Customer PC,
Phones– Central global database does inter-provider translation
On-net to off-net calls return IP address of destination gateway
– Central Database is ‘shared’ by providers– Transaction volume
At central db, number of inter-provider calls At services databases (800, call-blocking lists, …) number of subscribed
services At Provider and endpoints
NGN Solutions v7 – 13
NGN
Network Repositories – User data (profiles, lists) in multiple devices and databases– Central Server provides reliability– Updates to devices synchronized on re-connect – Synchronization on demand or periodically:– Local databases are caches– User mobility
Where should translation take place Should cache migrate Real-time constraints
– Transaction volume across devices, endpoints...
NGN Solutions v7 – 14
NGN
Directory Enabled Networks (Cisco)– LDAP interface to network resources– Schemas for network resources– Used for resource allocation for network services
Warehouses– Traffic warehouses– Equipment Inventory warehouse– Warehouse used for capacity management, billing, SLAs, ...
NGN Solutions v7 – 15
NGN
Object based services– Calls abstracted as object– Call models implemented within objects– Object mobility used to implement services
Call forwarding Third party call set-up
Objects for service creation– Tool-kit for third party service creation– Base Objects/components upon which to build
Device Independence– Migrate calls across device– Compose services across devices
NGN Solutions v7 – 16
Summary
NGN (competition) has forced – Distributed intelligence– Low-cost solutions
Telephone Providers want to jump on the dotcom bandwagon
Only a few (2-3 of current Telephone providers will survive
NGN Solutions v7 – 17
NGN Target End Customers
Small (2-99 employees) Business – Spend an average of $220/month on
telecommunications services Medium (100-499 employees) Sized Business Market
– Spend an average of $2,800/month on telecommunications services
Both segments are vulnerable to competition– Require a bundle of telecommunications services
Multiple telephone/fax lines High-speed Internet access Etc.
– Only 62% report “loyalty” to their incumbent LEC– Highly receptive to better, more complete offerings from
competitive carriers Source: The Yankee Group
NGN Solutions v7 – 18
Large (500+ employees) Sized Business Market– Spend more than $3,000 per month on telecommunications
services– Campus telephony and data networks often provided by
on-site resources and staff– Require advanced wide-area network (WAN) data services
and trunks from enterprise telephony networks– NGN services will focus on
Cost containment with bandwidth aggregation and self-service provisioning
Work-at-home services for telecommuters Advanced “follow-me” services for road warriors and office
hoteling Mixed voice/video/data services for advanced communication,
marketing, and customer service applicationsSource: The Yankee Group/Forrester Research
