2. Facts on IMS Integration,
Configuration & Deployment
• A complex and distributed
Multiple vendors architecture that requires an
and/or suppliers end-to-end- solution approach
• Many thousands of configured
Typically 20+ IMS parameters, all of which must
network elements be aligned for reliable service
operation
• Deviations from standard
Many thousands of
configurations can result in
configured parameters
performance problems and
major service outages
Distribution and • Majority of outages are due
geo-redundancy to manual misconfiguration
and breakdown of processes

5. Gambling with Your Network
Anecdotes without Configuration Audits
• Operations staff typed an incorrect IP
address to an out of region device causing
a 10 hour outage
• 2 day outage was caused due to incorrect
security settings on a device
• Security administrators adding accounts on
a device forget to issue “commit” command
eventually causing a reboot and loss of VoIP
services in market
• A service provider received an update
from their vendor. 3 way calling and call
forwarding did not work for 2 weeks due
to a misconfigured parameter
• Multiple week silent outage resulting in
100,000s of blocked calls due to
misconfigured parameter settings
• Service provider receives an upgrade from
their vendor, it takes 200 days to complete
testing with bulk of checks involved in
parameter checking

6. Expanding IMS, VoIP, IPTV Deployments
Customer expectations create challenges
Lab FOA City National
• Small scale test of • Slight scope expansion • Significant scope and team expansion.
technology deployment from Lab deployment • Parameter churn becomes unmanageable
(IMS, VoIP, IPTV) • Small operations team • Definition of Gold standard parameter
• Manageability through accessing network templating required
nodal interfaces • Parameter churn • Tracking and auditing of parameter changes
acceptable manageable through mandatory requiring integrated security
manual methods • Presence of solution blanketing manager over
solution network required
City/National deployments needs much different than Lab Trial or FOA
• Must normalize configuration/parameter mgmt and security across different NE types
• Need to inventory NEs across the network before deploying a service
Software upgrades cannot be done one NE at a time
• Impractical or cost prohibitive to log onto each NE
Most EMSs designed to take you to FOA ― but not beyond …
How do you go beyond FOA to City/National Deployments?

9. Conclusion
• Next generation architectures for VoIP, IPTV, IMS consist of many
inter-related elements each with thousands of parameters
• Stare and compare doesn’t work and is time-consuming and
error prone
• “Gold standard” or “Baseline template” approach to parameter
setting allows automation audits and eliminates “stare and compare”
• Outages due to misconfigurations eliminated
• Audits and upgrades can now be performed in maintenance windows
• Complex architectures more manageable allowing for large scale
deployments to proceed
