OTT usually seen as a threat. The clock is ticking…
![Page 5: Telco-OTT: infrastructure challenges and solutions](https://reader034.fdocuments.us/reader034/viewer/2022051013/5481345eb37959c22b8b46cf/html5/thumbnails/5.jpg)
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
Service quality
Immediate

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

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
