Service Assurance Definitions
•
Service Assurance - Maintaining the service
The timely response to and resolution of customer or network
triggered problems, tracking, reporting, managing and taking action
to improve performance for all aspects of a service

Sectionalization
Root cause analysis
Performance monitoring and alerting
Traffic trending
Congestion alerting

Service Provisioning
•
Service Provisioning - Installing the service
The flow through process involved in the installation, configuration
and activation of a service across multiple technologies and
equipment providers to provide an end-to-end service. This includes
•
•
•
•
•
Order Management
Workflow Management
Multi-domain activation
Multi-technology activation
Resulting in a fully automated provisioning process

Reality Check - the IP world
• The world has changed forever
• Traditional methods of managing and provisioning networks
no longer apply
• Best effort is NOT good enough
• QoS is now the most important issue
…We need to….

–
Provision it
Manage it
Measure it
Bill for it
• The result … ‘Service Level Agreement’

A century to install the world’s first billion phone lines;
in 10 years this will nearly triple to 2.8 billion total phone lines.
Today, > 200 million wireless subscribers; by 2008, this will grow 500% to
over 1 billion wireless communications appliances!

Service Assurance Challenges
•
•
•
Support Management across multiple vendors and technologies
Need to be able to measure and act pro-actively using thresholds
Best effort is NOT good enough
…….QoS becomes much more important !
QoS now relates to
• Network throughput/latency
• Congestion
• CPU utilization
• The challenge is to meet QoS NOT by Over Engineering BUT by
Pro-active management

Importance of software
Resulting Impact
Cost of operations
Market Forces are
driving need for
assurance of new
applications and
technology
Complexity
• Network complexity increases with implementation of new technology & services
• Life cycle costs are shifting from initial investment to cost of operations
SOFTWARE IS KEY TO “HARNESSING THE POWER & COMPLEXITY OF THE NETWORK”
•
•
•
•
Software will differentiate competitive networks
Software is critical to effective management of resulting operations environments
Software is the catalyst for achieving “break-through” improvements in operations
Software is critical to provisioning across multiple domains and technologies

Service Provisioning
Service Provisioning
•
The challenges service providers are facing in the management of
their networks arise from at least two different sources: the need to
weave a number of technologies into a seamless network and the
need to integrate a multiplicity of systems required managing the
technologies.
•
True Inter-Domain Configuration Management will enable service
providers to perform flow through end to end provisioning across all
technologies including: •
•
•
•
•
•
•
PDH
SDH
DWDM
SONET
ATM/FR
xDSL
IP.

Business Value
•
Cost savings due to reduction in manual work Leased Line, Frame
Relay Services Provisioning, xDSL subscription.
•
Additional revenue due to earlier turn-up of service
•
Cost savings due to reduction in manual work in Facility Design and
Implementation
•
Cost savings due to reduction in manual work in ATM-over-SONET
Infrastructure Provisioning
•
Higher customer satisfaction leading to increased market share and
reduction of churn
•
Ability to meet market demand ahead of competitors
•
Reduction in training costs
Lucent Technologies - Proprietary
35
Customer value
•
A flow-through provisioning architecture integrating ATM, SONET, SDH,
IP and xDSL technology domains.
•
Mechanization of network and service design and inventory
management tasks leading to large savings in operations costs
•
Revenue stream for newly-provisioned services begins sooner because
of a faster turn-up (provision takes minutes verses weeks).
•
Increase in market share due to
 Increasing customer satisfaction resulting in retention and
increased orders from existing customers.
 Ability to meet market demand ahead of competitors
•
Reduces training and operations costs by hiding complexity from the
user.

Conclusion
• Biggest OSS challenge to carriers is managing across
multiple technologies and domains
• Provisioning must be able to support new technologies from
a common Order Management and Provisioning engine
• The management of networks can no longer be based on
traditional best effort methods
• Service assurance is about combining fault and performance
management.
• Quality of Service is now the most important issue in the IP
world
• You can only guarantee Service Levels if you can proactively
manage your QoS through Provisioning and Service
Assurance
