A network of depth and breadth

• High capacity long distance network - 43,000km

• Connecting 22 countries, 39 metro networks and >150 cities

• 20 data centres and 19,000 connected buildings

• B2B only – no MNO

SIP Trunks (Enterprise and Carrier)

37 voice switches

1 softswitch

80% of voice volume (April ’13)

20% (growing) VOIP

• Colt is a member of the ETSI ISG NfV

• NFV is an element of Colt’s SDN vision

NFV is an important step to optimise and

integrate communication services

Software Defined Networking

Colt’s SDN vision is internally defined as “Network Programmability” and has two main components:

1) Bring computing paradigm to networking: make the network elastic,

scalable, on-demand and virtualised

2) Allow Application layer to communicate, through standard APIs, with

the network

The target is to integrate in the long term IMS functions,

UC and other applications within the SDN architecture

• Fully virtualised deployments on our standard compute platforms

• APIs for QoS, CAC, DPI, provisioning, billing etc. to allow

applications and network to talk

Future Voice Propositions

The OTT Question:

B2B ≠ B2C

• Regulatory (emergency calls, LI)

• Functionality (dialplans, CLI, IN, etc.)

• Resiliency (enhanced routing, disaster recovery)

• End-to-end QoS

… but for how long ?

… what about UC ?

… what about WebRTC ?

9

A new Aspect of OTT

WebRTC brings a new aspect into the OTT discussion:

Will WebRTC change the OTT landscape?

Is WebRTC a threat or an opportunity for Colt?

10

What does WebRTC mean for Colt?

• ‘real’ click-to-call

• Extending PBX DDI numbers to the web

• Integration with audio conferencing / WebEx

• Integration with UC and video conferencing

• Contact center solution enhancements

Extend existing products to native web-browsers

without plugins

1/3

Phase 1: Service Enrichment

Being prototyped

in Colt !

11

What does WebRTC mean to Colt?

• Virtual PBX

• Next-gen UC

• Next-gen video conferencing

Web-based realtime communication

(… w/o the need for a E164 number)

2/3

Phase 2: Possible future Solutions

How will this impact the architecture

and functionality of the future

communications core platforms?

12

What does WebRTC mean to Colt? 3/3

Phase 3: Future Core Infrastructure

How does the future Voice/VoIP environment look like?

• Large web-servers instead of an IMS core?

• How will WebRTC be integrated in IMS?

What about current developments?

• Do we need nat’l VoIP I/Cs with PTTs or will it be Internet? (*)

• Should we further (heavily!) invest in Number Portability?

• Etc…

(*) we have been asked this question by a PTT!

13

Summary

• Functionality of SIP trunks is there, next step is to reduce complexity

• IMS and UC platforms covered in the long-term by Colt’s vision of

Network Programmability (SDN)

• B2B SIP trunking less impacted by OTT so far due to more stringent

requirements, but this may change over time

• WebRTC has the potential to impact our future service offering and

infrastructure architecture

• The next 2-3 years will show if WebRTC becomes a game changer

or if it was a simple distraction
