Let’s get our Goals clear
• Open Source is Exciting and Attractive but it is NOT our GOAL.
• GOAL: To Offer Agile, Measurable, Billable and Assured Services
• Open Source is not a MEANS to achieve this goal.
• MEANS: Automation and Orchestration of Service Lifecycle across multiple domains.
• Open Source and Legacy Technologies are part of the IMPLEMENTATION of Agile,
Measurable, Assured and Billable Services across Multiple Domains.
• Legacy:
◆ Connectivity: Dedicated Layers 1-2-3, L2-L3 VPN,
◆ Nodal: Dedicated Servers, Cloud Storage, Firewalls, VMs, Routers, Switches
• Innovative:
◆ Connectivity: SDN
◆ Nodal: Cloud, NFV, Security, Routers, Switches
• Big-Data & Analytics
• Bringing it all together: Existing/Legacy/Brownfield
◆ Co-existence of Legacy and New
◆ Migration

Where should we go next?
• Don’t rush to build APIs. If the Data-Models and Processes at both sides of the API do
not match – the API is useless.
• Build industry-wide common Info-models and Data-models.
• Build industry-wide processes.
• The APIs will build themselves.
For Virtual Services to become a Reality - Roll off your sleeves and get to do the needful!
DEVELOP STANDARDS.

"I'll see pigs fly … before we all agree on a common data model,"
Network operators need to stand up and take
responsibility for that and for coping with the multiple
approaches.

Tower of Babel
Genesis Chapter 111 And the whole earth was of one language, and of one speech.
2 And it came to pass, as they journeyed from the east, that they found a plain in the land of Shinar; and they dwelt there.
3 And they said one to another, Go to, let us make brick, and burn them throughly. And they had brick for stone, and slime had they for mortar.
4 And they said, Go to, let us build us a city and a tower, whose top may reach unto heaven; and let us make us a name, lest we
be scattered abroad upon the face of the whole earth.
5 And the Lord came down to see the city and the tower, which the children of men builded.
6 And the Lord said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will
be restrained from them, which they have imagined to do.
7 Go to, let us go down, and there confound their language, that they may not understand one another’s speech.
8 So the Lord scattered them abroad from thence upon the face of all the earth: and they left off to build the city.
9 Therefore is the name of it called Babel; because the Lord did there confound the language of all the earth: and from thence did
the Lord scatter them abroad upon the face of all the earth.

The Hitchhiker's Guide to the Galaxy
Douglas Adams
"The Babel fish is small, yellow, leech-like, and probably the oddest thing in the universe. It feeds on
brain wave energy, absorbing all unconscious frequencies and then excreting telepathically a matrix
formed from the conscious frequencies and nerve signals picked up from the speech centres of the
brain, the practical upshot of which is that if you stick one in your ear, you can instantly
understand anything said to you in any form of language: the speech you hear decodes the
brain wave matrix.”
“We apologize for the inconvenience.”
