NGN Service Resiliency
Pathways to Market
Next Generation Networks (NGN)
 Next Generation Network
implementations are starting to
evolve around the world, including NZ
over the next five years
Integration of Network Services
 NGN’s integrate many disparate
services
 Unlike PSTN which is a single service
network
 Each service has its own characteristics
 Services have widely differing QoS
standards to meet for consumers and
businesses
 All services share the same network!
Service Resiliency and Availability
 Resiliency
 Able to withstand failures and faults
 Availability
 Proportion of time that the network is
able to accept requests for service
NGN Reliability
 Reliable networks and services will be
critical to all businesses and
consumers throughout the world.
 Reliability is essential if the network is
to transport all possible services!
 Telecom faced major problems last
year as a result of problems on two
diverse routes:
 Rats and post-hole diggers!
Product - 1
 A suite of tools that addresses the
issues of
 Measuring and monitoring service
resiliency
 Managing service performance, resiliency
and availability
 Designing networks to meet QoS,
availability and resiliency standards
Product - 2
 The toolset will be underpinned by
theoretical models of service
resiliency supported by actual
measurements and simulation studies
Project Products
 Service Resiliency Models with
associated measurement strategies
 Network Planning Tool prototypes
employing intellectual property from
the project
 Network measurement and
monitoring tools for service resiliency
Market Opportunity
 The intended market:
 Core network providers – eg Telecom NZ, Optus,
Telstra, Telekom Malaysia etc
 ISPs using the Telco core and/or their own
resources.
 This group consists of several hundred organisations
within Australia and New Zealand.
 However, the number of providers world-wide is
very much larger and thus it is envisaged that the
products would have a wide appeal throughout the
world, with particular emphasis on the rapidly
growing markets for the Internet in Asia, China and
South America as well as the traditional markets of
the USA, Europe and Japan.
 Providers of services to these providers – eg
Alcatel
Tool Requirements
 There is a need for products that will
enable providers to determine optimal
allocations of capacity and ensure network
resiliency and QoS guarantees for the
customers in their networks; this will lead
to efficient use of the network
infrastructure and reduce costs to the
consumer.
The Network Planning Problem
 What is it?
 Information today is handled on a very wide variety of
different networks that consist of nodes and links (“switches
or routers and transmission links”).
 The Next Generation Network will be based on IP technology
and support multiple service types.
 It is essential that the owners of these networks and
systems properly manage and plan them in order to service
their customers and their own communication needs.
 Clients using ISP/Telco networks need to be able to plan
their networks to meet customer requirements.
 An important requirement for Internet based users is Quality
of Service (QoS) since the “regular Internet” does not
provide QoS guarantees.
Making Services Resilient
 Key steps are:
 Ensuring that the
underlying transport
network is reliable and
robust to failure(s).
 Ensuring systems
supporting individual
services are also
reliable and robust.

Network Service Resiliency Models
 Methods being developed
to enable the measurement
of factors that contribute to
network service resiliency.
 Service resiliency should be
decoupled from physical
network reliability in order
to focus on things that
affect subscriber QoS.
 A combined physical and
service resiliency model is
the most likely outcome.
Network Management Tools
 The objective of these tools
is to monitor the
performance of the network
in an appropriate way and
ensure service quality is
being maintained.
 Service resiliency can be
measured in many different
ways

Revenue from Planning Tools
 Network planning tools vary considerably in
price but some of the more recent big
players ask for about $1million US for their
packages.
 The "APTNet package" that I helped
develop for Telecom Malaysia was expected
to fetch about $A350,000 per copy, but TM
backed off from selling it in the end and
only use it internally because of perceived
market advantage over competitors in their
environment.
Measurement Tools & Methods
 Measurement strategies embodied in
sophisticated tools (may be hardware or
software from this project) are marketable
or,
 If we get really fortunate, and develop a
methodology that becomes implemented as
an IETF standard or a patent, then we
should be able to collect royalties for this
and get a reasonable rate of return.
 If we link the outputs to inputs in the
toolset mentioned above, there is a
multiplier effect.
Network Monitoring
 Network monitoring of NGN services
is a really hot topic.
 The development of software and
hardware systems to achieve such
monitoring for a service provider like
Telecom would be hugely beneficial as
they can demonstrate in an impartial
way the level of service being
achieved by their customers.
Business Models
 There are many business and marketing models that
are possible, viz:

Develop a software package incorporating some or all of
the models and tools mentioned previously. (Different
bundling options can be chosen)
 Another version is to get the customer to pay upfront
for the Version 1 product and enter into agreements for
maintenance updates over a fixed or variable period.


Instead of selling the package, you provide
consultancies that use the package and retain the
rights. (Must maintain a team to do this – hard for
universities, though)
Rental/lease type options. Alcatel operates by providing
services to clients like Telecom NZ and so there can be a
return on investment in this way for Alcatel. Telecom
could get the consultancy services for free, for example.
