Strategically deployed, passive
instrumentation on internet access
links provides an ideal vantage point
to monitor for metrics and KPIs,
service flows, and packets for gathering
statistics and then analyzing them.
Detailed performance views via refined
graphs, reports, and tables can be
utilized to reduce overall MTTR associated
with troubleshooting, traffic engineering,
and/or capacity planning for these
critical, value-added service links.
The analysis of internet services
will reveal:
- Total Internet traffic
volume by customer in real-time
and over time to identify busiest
sites and areas of the network
- Utilization
of different subscriber services
and content types, such as streaming
voice and audio media, VoIP, web
browsing, or email to validate
prioritization and routing decisions
- Hosts,
conversations, and response times
for specific URLs to troubleshoot
HTTP errors
IP MPLS Core Bearer Network
Many telecommunications providers
have introduced MPLS-based VPN service
offerings to satisfy increasing demands
for secure, cost-effective transport
of converged voice and application
traffic to high-value business customers.
As enterprises take advantage of
newly introduced services that break
out delivery for voice and video
into high priority classes and tiered
choices for their more latency-tolerant
business applications, service providers
are challenged to meet service quality
expectations.
Again, sophisticated performance
monitoring solutions that gather
and analyze the collected statistics
from MPLS-based VPN networks offer
essential services visibility in
the form of real-time and historical
graphs, reports, and tables that
can be used for troubleshooting,
traffic engineering, and/or capacity
planning purposes. The analysis of
traffic flows over MPLS core bearer
networks will reveal:
|
|
- Services-aware
analysis of utilization
and traffic volume
across the MPLS core
- Traffic-flow and
response times between
individual customers
and locations by
services such as
voice, data, and
internet services
to troubleshoot problems
with valuable new
Triple Play offerings
- In-depth, packet-level
details of an individual
customer’s
activity to analyze
and discover the
root cause of degradations
- Bandwidth and services
utilization of circuits
highlighting individual
VRFs to recognize
changes in bandwidth
or new QoS traffic
prioritization schemes
that may be needed
to accommodate
“power user” customers
or locations.
It is easy to see
the opportunity to
increase market share
and revenue from fast-rising
demand for XoIP services
for providers around
the world. Reducing
customer churn will
be the challenge regardless
of which technologies
are deployed. Having
the appropriate visibility
into the services delivered,
the customers using
them, and the network
infrastructure delivering
them will be an essential
part of a successful
service delivery strategy.
Service providers that
embrace customer experience
by moving beyond traditional
infrastructure-centric
approximations of service
delivery will be in
the best position to
retain customers and
assure their portion
of success within the
XoIP services market.
