This document discusses the need for carrier cooperation and LSO (Lifecycle Service Orchestration) to enable fast provisioning of services from minutes to months. It outlines how global connectivity used to be provisioned in minutes through carrier cooperation but deregulation and new technologies led to fragmented networks. The alternative proposed is defining network slice services and using LSO to automate cross-carrier provisioning through standard APIs. This would allow services like a 2GB L3VPN to be provisioned within minutes across multiple carriers instead of months.

MONTHS TO MINUTES:
THE CASE FOR CARRIER
COOPERATION AND LSO

MISSION IMPOSSIBLE?
Customer Wants:
● L3VPN with specific E2E speed, QoS, and
security
● E.g. 2GB symmetrical guaranteed BW
● Ten minutes from order time to turn-up
● For a two hour design review
● Doesn’t want to pay very much

CIRCA 1966
• Single service: Voice
• Global automated connectivity in minutes
• Based on carrier cooperation

THEN AGENTS OF
CHANGE HAPPENED
 Computer communications
(data)
 Deregulation
 Terminal equipment
 Breakup of PTT monopolies
 Multiplay services
 The Internet
 Technology
 VLSI
 Fiber optics
 Radio

WHICH CREATED AMONG OTHER THINGS …
Multiple overlapping
global networks to
serve multi-national
enterprises

12. ECI Proprietary 12
SITUATION UNTIL
RECENTLY
 No unified service definitions
 Each provider adopted his own
definitions of services
 Created international walled
gardens and made huge profits for
OSS/BSS providers
 High speed service take ages
to fulfil
 Eons if crosses several providers
 As long as there was money
rolling in, nobody cared

13. ECI Proprietary
AND THEN EVEN
MORE CHANGE
HAPPENED
 High Speed Internet
 Cloud Service
Providers

14. ECI Proprietary
RESULTING IN …
Global service providers
competing with themselves:
International “closed
garden” networks
versus
“Good enough”
Internet-based solutions

THE ALTERNATIVE
Customer Wants:
● L3VPN with specific E2E speed, QoS,
and security
● 2GB Service
● Ten minutes from order time to turn-up
● For a two hour design review
● Doesn’t want to pay very much

YOU CAN’T ALWAYS
GET WHAT YOU
WANT

Economics dictates that
customers will figure out a
way to make an inexpensive,
“good enough” service work

17. ECI Proprietary
BUT WHAT IF THERE
WAS ANOTHER WAY?
17
 Full Speed/QoS/Security
expectations
 Value-added private
network services
WITH:
 Fast turn-up limited time
services
 Price competitive with an
Internet solution

18. ECI Proprietary
IT’S THE
INTEROPERABILITY
STUPID
 SDN and NFV moved the
industry forward in terms of
creating unification and vendor
agnostic networking
 However the elephant in the
room is the lack of carrier
agnostic services
 For carriers to provide a
dynamic network they need
unified automated carrier-to-
carrier connectivity
18

19. ECI Proprietary
WHAT IS REQUIRED
19
Mindset change:
 Service Provider cooperating
instead of self-cannibalizing
Technically:
 Network slice service
definitions
 LSO for fast E2E network
slice implementations
