Chapter 10: Service Assurance for Triple-Play Services
Components of an Integrated Service Assurance Solution
A comprehensive service assurance solution should address the
correct mix of business processes as defined by the Enhanced
Telecom Operations Map (e-TOM) model:
– Service Problem Management
– Service Quality Analysis/Action and Reporting
– Resource Problem Management
– Resource Quality Analysis, Action and Reporting
Many service providers make the assumption that the network
equipment providers, or outsourced solution providers, will
provide the majority of this functionality with the aim of
leveraging their existing investments in their OSS infrastructure
and tools. However, as time passes and service deployment
volumes increase, many providers express the following concerns:
1. What happens when I have multiple vendors with different
approaches?
2. How do I get more visibility of the service performance (higher
layer applications), not just the network performance (layer 1-2
applications)?
3. How do I build an operations support environment that scales
independent of vendor-specific element solutions?
4. How do I create a common toolset across the organization to
optimize available resources while avoiding vendor-specific
specialization?
A comprehensive service assurance solution will combine
elements of the e-TOM model, described in more functional terms
in the following Service Assurance Model.
