OTT usually seen as a threat. The clock is ticking…

Changing telco response to OTT Old §  The OTT threat is miniscule §  Those are low-value minutes §  Those are not minutes that would have

been on my network anyway §  OTT’s don’t make any money §  Our IMS services will be better

New §  What if IMS (& VoLTE/RCS) doesn’t work? §  How do I encourage more data usage? §  Can we get in on the OTT action?

OTT service delivery challenges

Imminent

• Quickly adjust to changing service needs • Works with many infrastructure & client devices

• Federates with network service providers

Flexibility

• Protect user information • Maintain service availability during attacks

Security

• Current expectations: E911, lawful intercept, taxes

• Expect more IP network regulations, not less

Regulatory compliance

• Cost effective at low & high-end • Able to start small & grow rapidly

Practical core session management

• NAT & firewall traversal (i.e. HTTP & HTTPS only)

• Near PSTN-quality – media & availability

• Consistent experience across devices & interfaces

OTT service delivery implications

Immediate Imminent

• Light weight, dynamic core session management

• Smarter clients vs. omnipotent core for scalability

Practical core session management

• Client-side technologies to overcome packet-loss & jitter

• Make all traffic look like web-traffic (http & https, SSL, etc.)

Service quality

• Off-the-shelf, but programmable for flexible, rapid changes

• Quickly interoperable with any device & network

Flexibility

• Robust, service-intelligent security

Security

• Out-of-the box regulatory compliance

Regulatory compliance

§  What is WebRTC (Real Time Communications)? §  Emerging method of web-based

RTC §  Another type of access

framework, same session delivery challenges

§  Why the hype? §  Web: most dynamic, innovative

place on planet §  RTC has largely been absent §  WebRTC delivers RTC to those

that create the Web §  Why should you care?

§  WebRTC will be an important access method in the future for SPs, contact centers, and enterprises

What is WebRTC?

Expand footprint - Extend existing services to new

subscribers

Decrease churn - Enhance current services to

existing subscribers

New service revenues – Create new services and

subscribers

Telco-OTT increases customers & revenue
