Industry macro context
▪ Cost per bit is expected to exceed revenue per bit for most CSP during 2017-2018 (Tom Nolle –
CIMI Corporation blog)
▪ CSP revenue growth continues to slow down (between 2010 and 2014, the industry’s revenue
growth decreased from 4.5% to 4%)
▪ CSP Data traffic continues to increase by multiple orders of magnitude (e.g. AT&T recorded a
150,000% increase in data traffic on its wireless network between 2007 and 2015)
▪ Many CSP executives foresee significant digital disruption. McKenzie estimates a resulting 35%
increase in profits, however improvements topped 9% at best after significant investments

MEF OVC Service Overview
"Reproduced with permission of the MEF Forum."
• Develop new service models to abstract
and bridge physical, logical, and virtual
network resources
• Expose normalized objects to customer
facing processes and applications
• The unified data model supports dynamic
service composition regardless of
underlying physical & virtual resources
• Enable service chaining, segment routing,
and network slicing
• End-to-end security, access control and
authentication

Network Binding Layer
Discovery across Vendors, Domains, Technology & layers
Service Layer
L2 VLAN L3 VPN
Physical Config &
Topology
Logical Config
• Real-time accurate discovery of
network resources physical,
logical, virtual.
• Reverse-engineer and present
an up-to-date network topology
• Expose actual configurations
as the foundation for other
management and control
functions
• Abstracted metadata driven
network model independent of
naming convention(s)
