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

Unified Service Model

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)
