The Internet + : A non application-specific transport network: Just like the Internet! It IS the Internet – just extended: + Delivery to the users, on LANs and to smart phones + Prioritization for real-time traffic - Just enable diffserv + Metering and charging of “beyond Internet usage” Good for everyone: The SDN is not needed, - IP connects end-to-end - SIP is a self-routing also for the Telcos: Provide something better, - and users will pay for it.. Bill the better!

Bill the better! Enable the new services, interoperability and the standard we need and want! At the same time: - New Telco revenue - Vast Telco infrastructure savings How to do? Easier than believed!

6. © 2012 Intertex Data AB 6 Session Delivery Network (SDN) and IMS Sorry, it’s POTSoIP  SIP has been Used to Replace Pieces of the PSTN Maintaining Old Structures  POTSoIP  We had a cloud that could transport all communication, including voice and UC.  Today, we use the Internet for all smart communication, but lack global real-time communication, multimedia or UC.  We get the 100 years Plain Old Telephony Service (POTS) - maybe cheaper and more flexible. But is this the way forward?

7. Internet Internet has Shown the Success of a Cloud! We need this for global UC: With: 1.All you can do with SIP - UC 2.Full mobility 3.Numbers and SIP addresses 4.Quality up to Telepresence 5.Interoperability – Don’t GW, unless required 6.Delivery to the users SIP Connect 1.1 Internet + But got this (SDN/IMS): (Wires on top of the cloud!? Wasn’t creating the cloud the success?) MPLS Session Delivery Network (SDN) = POTSoIP

10. © 2012 Intertex Data AB 10 It Should be of Utmost Interest for the Telcos  For real-time usage, we need an Internet pipe with prioritization enabled - not just for telepresence quality, but also for 2G, 3G and 4G wireless real-time usage with smart phones  Has to be charged separately. If not, it would be used for everything and we are back at all usage being at the same quality level.  And we don’t want our smart phone batteries drained  And we want to use both phone number and addresses – not the many island. Telephony Income (highly charged) Low Charged Internet Bandwidth Quality Bandwidth New Income Data RTC Telephony + Internet + Economy Skype etc. Internet and Telephony Economy Bandwidth Usage Data RTC

11. Internet + Model ENUM DNS EMS TR- 069 SIP Connect 1.1 PKI The Internet with Quality Enabled Global IP Transport Network All SIP Routed Everywhere (Not Gatewayed! Via SIP Proxies – Not B2BUAs) The TOQrouter – Trust, Openness, Quality – is a routing SIP proxy, a billing meter, and with built in SBC.

12. Most Important: SIP Everywhere – Just like HTTP! We would not have the Web, if HTTP did not go between the Browser and the Web server. Today SIP is stopped and limited by Firewall/NATs, SoftSwitches and bad SBCs. The TOQrouter is a standard compliant SIP proxy (and SBC) that routes all SIP between the Users and Servers according to RCF 3261. The TOQrouter is not interfering with the usage of the SIP communication (like today’s plumbing), but can measure the usage for billing. Proper SIP transport (by routing SIP proxies) is required: For all beyond POTS usage, UC For eliminating network incompatibilities – Interop issues are then reduced to being only between clients and services For mobility: User and services can be anywhere! For global UC: Clients, PBXs, Cloud services etc. only have to use a standard SIP interface. There is no other way to go!
