Why do Hand-picked Cherries... (2009)

  1. 1. Why do hand-picked cherries provide no guarantee for a tasty pie? Copyright © 2009 Alcatel-Lucent and Nakina Systems Inc. All Rights Reserved.| 1
  2. 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 Copyright © 2009 Alcatel-Lucent and Nakina Systems Inc.

  3. 3. Need for IMS Configuration Management and Audit Tools Risks What’s needed ? • Increased solution management • Lifecycle management approach costs and risks • Mechanisms to discover settings in • Delayed service launch due to each device, compare to planning poor end-to-end performance and update the network or compatibility issues • End-to-end automation and • Inability to isolate and resolve operations intelligence for faults due to non-standard improving decision making and provisioning and configuration reducing the number of manual • Sub-optimal performance in parts touches (or all) of the architecture • Rapid configuration and para- • Inability to complete audits and meter discovery and auditing upgrades in maintenance windows • Control of maintenance • Network expansion hampered procedure for by lack of real-time network a confident baselining capabilities network expansion Copyright © 2009 Alcatel-Lucent and Nakina Systems Inc.

  4. 4. Critical Components of IMS Solution Lifecycle Management • Labs & engineers • Documented • Configuration configurations • Methods & tools control • Standardized • Multiple test-beds • Ongoing audit processes • Multi-vendor & remediation coordination Design Test Operate Change Management • Documentation management • Release planning and coordination • Change control & release management • Feedback for future releases Copyright © 2009 Alcatel-Lucent and Nakina Systems Inc. All Rights Reserved.| 4
  5. 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 Copyright © 2009 Alcatel-Lucent and Nakina Systems Inc.

  6. 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?

  7. 7. Need for IMS Configuration Management and Audit Tools Challenges Solution Benefits • Complex, distributed • End to end automation and operations architectures with thousands of intelligence enables improved decision individual parameters making by mechanizing network infrastructure changes in a controlled • Majority of outages due to and secure environment manual misconfigurations and breakdown of manual processes • Automation of customer method of procedures (MOPS) and reduction of • Inability to complete audits and manual touches upgrades in maintenance windows • Rapid parameter and configuration discovery and auditing • Network expansion hampered by lack of real-time network • Control of maintenance procedure baselining capabilities providing confident network expansion Complex architectures consisting of multiple elements with 1000s of parameters Copyright © 2009 Alcatel-Lucent and Nakina Systems Inc.

  8. 8. Network Integrity Control Enforce & compare NW parameters en-masse Service Provider Pain Planning Integrity • No mechanism to enforce parameter control or Control Integrity Systems Templates Control Integrity permit parameter baselining Templates Control Integrity Templates Control • No visibility of global network settings and state Templates • Challenges in management of complex groups of elements within a given maintenance window Domain Control and Nakina Network Resource Optimizer Intelligence Modules • Parameter Discovery Workflow Engine - Powerful, flexible mechanism to extract Configuration Parameters including inventory Virtualized Nodal • Comparison – Audit for Discrepancies Management Services - Compares “Standardized templates” or Base Communications, Transaction Planning tool reports to live Network View – Engine & Security Layer using specified Tolerance Criteria - Displays and reports discrepancies • Integrated Security Solution - Profile-based protection of access to network information - User activity logging Copyright © 2009 Alcatel-Lucent and Nakina Systems Inc.

  9. 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 Copyright © 2009 Alcatel-Lucent and Nakina Systems Inc.
