Agenda

• Definitions• Where are we going with IP?• Why is service assurance so important in today’s world?• The provisioning challenge ...domain, domain, domain• The importance of software in the network• The SA solution, examples and value• Service provisioning challenges, examples and value• Conclusion


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

• Fault mgmt• Sectionalization• Root cause analysis• Performance monitoring and alerting• Traffic trending• Congestion alerting• Trouble ticketing• Congestion control• Links to provisioning

• Resulting in a high Quality of Service


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


Industry direction is challenging operators

• High Speed Access• Data Equipment Proliferation • Architectural Convergence• Architectural Transition • One Stop Service Shopping • Service Differentiation • QoS Based Services• Service Level Agreements• Carrier InterNetworking• Network Partitioning

Directions

IndustryDrivers

• InterDomain & Multi-Vendor Management

• “Monitorable” QoS & Customer Service Mgmt.

• Convergent Solutions for Multiple traffic types

• Single seat integration

• Automated Service restoration

• Centralized and distributed provisioning,

• Plus: Reduce Cost/Intervals• Improve Quality•Correlation of many alarms (very important)

Complexity

Resulting Impact

Market Forces are driving need for assurance of new applications and technology

• 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

Value to Customers

• Meet future Network Management needs as carriers evolve to Multiple Service Networks

• Network troubles are quickly identified and corrected

• Proactive resolution of faults

• Manage complex networks comprised of diverse technologies

• Scalable from a few to thousands of Network Elements

• Easy to use, configure and flexible

• Provide maximum system availability

• Optimize reliability and capacity of multi-service network




• 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.


Requirements

Industry is at a cross road

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


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
