1. Why NGN?
Technological necessity of NGN
Does the Internet continue to evolve?
The Internet created various applications thanks to the freedom of end-users.
Does it apply to IPTV, Web 2.0, or FMC?
Best-effort QoS: New applications are hard to develop
Commercial quality real-time communications are difficult to provide
TV conference, streaming, …
Security/Reliability: Not carrier-grade
Children/elders can’t apply patches everyday
Mobility: the next bonanza will be in mobile gadgets
Current (ordinary) IP assumes fixed network
Discussions at Linux Symposium (2006)

Limitation from IP’s principle

Routing table
Packet (header + payload)
• Routing table are updated in local manner; no network-wide, no
equipment-wide sync  scalable and cheap, but no QoS guarantee
becomes possible
• No state in routers; minimize memory access  expandable and
faster, but traffic engineering becomes unavailable
• Very limited functions in networks  interoperable ‘Internet Protocol’,
but no security, no QoS-awareness
The problems tightly linked with IP principle and merits
7
IP Design Philosophy: Main Goals
• Effective multiplexed utilization of existing networks
– Packet switching, not circuit switching
• Continued communication despite network failures
– Routers don’t store state about ongoing transfers
– End-hosts provide key communication services
• Support for multiple types of communication service
– Multiple transport protocols (e.g., TCP and UDP)
• Accommodation of variety of different networks
– Simple, best-effort packet delivery service
– Packets may be lost, corrupted, or delivered out of order
• Distributed management of network resources
– Multiple institutions managing the network
– Intradomain and interdomain routing protocols
Grosshauser (2002)
8
Characteristics of the Internet
• The Internet is
–
–
–
–
Decentralized (loose confederation of peers)
Self-configuring (no global registry of topology)
Stateless (limited information in the routers)
Connectionless (no fixed connection between
hosts)
• These attributes contribute
– To the success of the Internet
– To the rapid growth of the Internet
– …and the difficulty of controlling the Internet :<
Grosshauser (2002)
9
Operator Philosophy: Tension with IP
• Accountability of network resources
– But, routers don't maintain state about transfer
– But, measurement isn’t part of the infrastructure
• Reliability/predictability of services
– But, IP doesn’t provide performance guarantees
– But, equipment is not very reliable (no ‘five-9s’)
Downtime: IP networks: 471min/year, POTS: <5min/year
• Fine-grained control over the network
– But, routers don’t do fine-grain resource allocation
– But, network self-configures after failures
• End-to-end control over communication
– But, end hosts adapt to congestion
– But, traffic may traverse multiple domains
Grosshauser (2002)

But operators cannot rely on PSTN services any more

In most developed countries,
2000 or around was the peak of telephone traffic
11
We must make Operator-friendly IP networks
IP traffic
>
telephone traffic
May 2006: 524Gbps
Fiscal 2004: 34.1Gbps
(Public Internet in Japan) (in Japan: converted 533k Erlang
using 64kbps/call)
> 20%/year
> -5%/year
IP must be the base of future networks
Timeline
• NTT: trial starts by the end of fiscal 2006
• KDDI: Fixed network becomes all-IP by fiscal 2007
• BT: by 2008
• Korea: long-distance is by 2007, local by 2010
12
NGN: best mix of packet and circuit
• "Service Stratum" for per-session control of packet transmission
• Data is transmitted with IP packet for interoperability
• All necessary functions are in the network (fat network approach)
– Operators can maintain every aspect of functions  increase reliability
– All the terminals can do is just to call network’s functions  increase
security
– Control interface is open  promotes development of applications

2. Standardization process
De jure standards v. De facto standards
De jure standards
• Open and fair process
• Results are shared among
all participants (usu.
without charge)
• Reflects broader opinions
ITU, ISO, TTA, TTC, ..
In NGN
framework
De facto standards
• Operated by highly
motivated volunteers
• Faster standardization
• Currently very popular
IETF, TMF, WiMAX, ..
Individual components
and technologies
NGN framework includes regulations and policies
(e.g., how to standardize emergency services, how to design market regulations
considering network architecture)
 De jure standards becomes important

IMS (IP Multimedia Subsystem) overview
• Provides various SIP-based services
– Provides session control, charging, security functions
• Increase end-user’s experience by unifying registration,
authentication and charging
– Provides interfaces to control transport functions
• QoS, media gateway, alignment of charging on transport
functions and service functions
– Provides interfaces not only to operators, but 3rd party
application vendors
• Clearly defined SIP from operator’s point of view
– IETF SIP is not enough for network operators
e.g., IETF SIP does not define the start and the end of
charging
• ITU-T NGN refers 3GPP Release 7 IMS
28
IMS for NGN (Y.2021)
• CSCF (Call Session Control Function): SIP server, the core of this
architecture. P-CSCF (Proxy CSCF) is a sip server that communicate
with user terminals
• Various functions are defined as the gateway to other networks

– Various message flow and protocols are defined, operators will choose

• Interconnectivity test planning, promotion and coordination,
including the coordination with relevant fora
• Studies regulatory issues of IP telephony, in particular QoS and
•
functionality, safety and security,
interconnectivity and
interoperability as well as regulatory issues of other advanced
services. Practices proving test, if necessary.
• Promotes R&D and the standardization of its results by
establishing basic strategies and promotion methods, and by
practicing proving tests. R&D focuses not only on NGN R1&R2,
but beyond R2.
• Promotes deployment and information exchange of next
generation IP networks. Publicize appropriate information through
publications, symposiums and market promotions. Surveys
domestic and international R&D trends.
