WHAT WENT WELL?
Metaswitch Networks | Proprietary and confidential | © 2014 | 6
Collaborative team working Onsite support Weekly management calls
Voice Design has stood up well
WHAT WENT WELL?
Metaswitch Networks | Proprietary and confidential | © 2015 | 7
Clearwater has performed well in testing Open source products work in real networks
So far the expected business case benefits of NFV & SDN look like delivering 100% Reduced investment & operational Costs Faster time to market Simplified ongoing platform management
WHAT WENT WELL?

Virtualized product deployment gone well
WHAT DIDN’T GO SO WELL?
Metaswitch Networks | Proprietary and confidential | © 2014 | 9
Metaswitch Fixed Line IMS solution didn’t fit neatly into the Manx Network IMS in the real world Manx IMS network doesn’t always follow the specs Had to continue to run existing network
Recognition that the end to end solution is key SAAS model was originally confined to IMS core software Metaswitch original view that is a make a “our” software work exercise Not possible to succeed with that approach – need to understand the whole solution
for project success.
Integration to retained network components Had to develop custom features to match existing function
IMS TAS Some complex SIP issues
HSS Non standard authentication Had to develop custom features to match existing function
PROJECT CHALLENGES - IMS

Initial virtual platform design did not behave as expected Resiliency is much more complex and capable in virtualised world and
needs comprehensive testing plan Virtual Networking requires a significant mind set change for traditional
networkers Technology is evolving rapidly
PROJECT CHALLENGES – I/PAAS PLATFORM FOR TELCO
Metaswitch Networks | Proprietary and confidential | © 2015 | 11
Telco operating model needs be clearly understood, Telco guys don’t get Virtualisation Require IT or Cloud team with
strong networking skills to support the I/PAAS platform
Telco guys own supporting the software application

Open Source software Manx early deployment of Clearwater Some teething issues but working wellOpen Source software works
IMS in real world Required flexibility and agility to address issues found in testingIMS can be deployed in multi-vendor environment
Virtualization Separating hardware and virtualization layer from applications Virtual networking can be challengingVirtualization works
Timelines challenging Some issues have caused delaysProject has reached migration phase in 10 months – final hurdle
