In addition to the
network layer testing covered above,
the CSP is becoming increasingly
dependent upon the performance of
the application layer as services
become decomposed into a collection
of application components. Technologies
such as VoIP and IPTV are well known
examples of this process in action,
however, the advent of IMS (IP Multimedia
subsystems) and the fixed mobile
convergence movement are true catalysts
for the increased dependency on application
layer performance. As the migration
occurs, the CSP needs to consider
adding an additional layer of service
performance testing – which
is very different from that used
for network based services. In the
decomposed services world, the reliance
on technologies like SIP and Web
Services creates a new level of complexity
in monitoring service performance

rapid time to value and
a deeper knowledge of the
performance of the infrastructure
and the services. It is
from this position of knowledge
that the CSP can look to
fill in the gaps in the
performance picture with
purpose built appliances
that provide very granular
and service specific performance
data. Now that the CSP
has the service performance
data it must leverage analysis
tools to proactively address performance
problems before SLA’s
are impacted and leverage
capacity planning tools
for planned upgrades and
directed maintenance. |

and identifying the
root cause of service degradation.
In order for CSP’s to effectively
monitor this new infrastructure, they
must invest in application transaction
monitoring systems that provide instrumentation
at the application layer that monitors
all transactions, creates a baseline
for transaction performance and identifies
the root cause in the case of a transaction
failure or degradation. CSP’s
also need to resist the temptation
to look at this infrastructure separate
from the network infrastructure, this
is just another component of the holistic
service performance view and as such
it should be tightly integrated into
the overall service performance management
solution.
In summary, service
performance management is essential
for CSP’s to deliver services
at the quality levels the marketplace
is demanding. By taking a pragmatic
approach to service performance management,
a CSP has the opportunity to build
upon their existing infrastructure
and ensure that any additional investments
are made in areas that provide a significant
return. The process began with creating
a solid performance management foundation
to establish a baseline.
From that foundation a
CSP can overlay a service
performance management
infrastructure leveraging
embedded capabilities in
the network; this provides

CA is uniquely positioned
to assist CSP’s in these efforts.
As a management vendor, CA is the
only vendor that offers a multi-vendor,
multi-technology, integrated and
scalable solution to this complex
problem. The combination of CA’s
eHealth, SPECTRUM and Wily Introscope
offers an integrated solution for
service performance management that
spans the legacy and next generation
infrastructures. These solutions
are proven in the marketplace with
installations in the majority of
CSP’s worldwide. CA’s
eHealth network performance management
application provides a central repository
for all network performance data,
inclusive of network elements and
service performance probes. CA’s
Wily Introscope provides complete
insight into the application delivery
infrastructure, monitoring all transactions
and identifying degradations or failures.
Finally CA’s SPECTRUM provides
the cross domain correlation and
root cause analysis capabilities
that CSP’s require to ensure
service quality is maintained and
operational efficiencies are optimized.
This integrated solution set is fully
modular allowing CSP’s to invest
only in the components that address
today’s needs and overtime
achieve incremental value by adding
additional components as requirements
change or expand.
