The hidden secret ofTCP/IP and theInternet.And how it affects your realtime platform.Olle E. Johansson * email@example.com * Twitter oejCopyright Edvina AB, Sollentuna, Sweden 2012.All rights reserved.1995.The revolution starts.17 years later and we’restill imitating a PBX.Time to change.
The PBX• Key line systems wasintroduced in the 50’s• One phone, multiple lines• The enterprise PBXwas introduced in the1960’s• Lowered the cost• internal calls where free• reduced need for outsidelinesPhoto: Joseph A. CarrThe PBX was the heartof the company.And the receptionist knew everythingworth knowing in the company.• This is old stuff.Photo: City Light Photographic Negatives (Record Series 1204-01),Seattle Municipal Archives
And the PBX is nolonger in the center.Cell phonesSkypeFacebookIM / ChatPresenseE-mailWhat’s the theme here?The glue that makes this architecture work.
What does thislong word mean?INTEROPERABILITYThe glue that keeps the Internet going.EROPERABILITYINTEROPERABILIINTEROPERABILITYAn agreement.INTEROPERABILITY.
A promise.INTEROPERABILITY.A lot of work.INTEROPERABILITY.What drives it?
Customers.Without customers controlling us, we can do whatever wewant.And what our marketing people want.Results in the 90’s:After many years of work.TCP/IPE-mailWWWLDAPTLS

Trademarks.Companies with one service. No interoperability. Nodistribution.Total dependency.We’ve gone backwards.I’m old enough to remember the past.IBM SNANovell IPXMicrosoftLan ManagerCC mailMS MailDecNet
IBM SNANovell IPXMicrosoftLan ManagerCC mailMS MailDecNetThis is exactly whatcustomers wanted toavoid.Customer pressure delivered the PC, Unix and TCP/IPnetworks. Freedom from lock-ins from vendors.Saving money by protecting your investment.Who took over?Venture capital. Large companies.Ask yourself.How does this affectthe PBX?
We’re movingbackwards in time.No focus oninteroperability.Lync. Skype. Many others.Failed interoperability.For years.SIP SIMPLE Presense and IM.
Proprietary telephoneprovisioning protocols.Digium - the ”open” telephony companyWebRTC won’t help.WebRTC just makes it easier to provide proprietarycommunication systems.It’s time for all ofyou to wake up.Good morning!
WAKE UP!Stop blaming thevendors.They sell what you buy. It’s in their best interest to lockyou in. Keep you in control.The one withmoney has control.You are the customers. Use your power!
<break>Think about it for a while. Do you really want to becontrolled in your business? Limit your choices?What hashappened in theworld of SIP?Quite a lot.And nothing.RFC 3261 waspublished in 2002.Implemented to 80%.20022012
SIP is based on the IETFarchitecture for TCP/IP.10 years.And we still need to learn.20022012Distributed.Domain-based federation. A network of networks.20022012Scalable.Stupid core. Intelligent endpoints.20022012
Connected.All hosts should be able to contact any otherconnected host.20022012Extensible.SIP solves one problem: Session management.What you do with it is up to you.20022012Where and when werethese rules deﬁned?Stupid core. Intelligent endpoints.Connectivity end2end.
the goal is full "open systeminterconnection": an Internet host mustbe able to interoperate robustly andeffectively with anyother Internet host, across diverseInternet paths.RFC 1122, 1989However, isolated LANs seldom stay isolatedfor long; they are soon gatewayed to eachother, to organization-wide internets, andeventually to the global Internet system.In the end, neither the customer nor thevendor is served by incomplete orsubstandard Internet host software.RFC 1122, 1989RFC 1122, 1989So where did we go wrong?We’re stuck with a 50 year old PBX architecture.A telco model forced onto the TCP/IP architecture.
I have at least ﬁve chatapps, six voip apps.Using separate islands of communications. It’s way toocomplicated for someone soon 50 years old.E-mail doesn’twork that way.Take control of ourcommunication.After 50 years with the PBX, we need to think in newways for IP based realtime communication.1. No inside/outsideBYOD and 3G devices killed that paradigm.
2. Be able totrust the system.Apply Security.3. No vendor lock-insBe in control of your communication system.4. Don’t trust yourself.Be open for innovation and evolution.
5. It’s personal.Focus on the individuals.6.Video everywhere.With WebRTC two-way video will be in every browser.7. Build for globalcommunication.TCP/IP is both IPv4 and IPv6 today. Internet growth inEurope will only happen in IPv6.

SIP2012 :: Deﬁningmodern requirementsHelping customers procure better systems.Interoperability inrealtime communications.SIP done right.As required by customers.Here’s whatI wantyou to do.
Aim to retire the PBX.Your company will survive.Migrate away fromone-company-one-brand systems.Require interoperability.Update yourspeciﬁcations.Refer to the SIP2012 reference proﬁle whenbuying SIP equiment and software.
For SIP trunks:Refer to SIP Connect from the SIP Forum.Customers:Please takecontrol.www.open-stand.orgI want to be free.If you don’t want to be free, call your nearest<large company> representative today andask him what you should buy next.And give him full access to your credit card too.
