The Problem Stated by Henry
Not counting I-D pages

950 SIP pages, nebbich
  • Just one 3GPP recommendation with the mighty
    title
  • Digital cellular telecommunications system (Phase
    2) Universal Mobile Telecommunications System
    (UMTS) Signalling flows for the IP multimedia
    call control based on Session Initiation Protocol
    (SIP) and Session Description Protocol (SDP)
    Stage 3 3GPP TS 24.228 version 5.14.0 Release 5
  • features 715 pages
  • ETSI TISPAN (dealing with IMSoFA) created over
    2000 temporary documents in 2005
  • Some say this is already pathological (S4)

IMSoFA IMS over Fixed Access (WiFi)

Systems Standards Stockholm Syndrome
  • S4 - Systems Standards Stockholm Syndrome (John
    Waclawsky, Mobile Wireless Group, Cisco BCR
    June 2005)
  • The Stockholm Syndrome describes the behavior
    of hostages.
  • The System Standards Stockholm Syndrome (S4)
    describes the behavior of system standards
    participants who, over time, become addicted to
    technology complexity and hostages of group
    thinking.
  • S4 applies specifically to systems standards
    participants who suffer repeated exposure to cult
    dogma contained in working group documents and
    plenary presentations.
  • By the end of a week in captivity, Stockholm
    Syndrome victims may resist rescue attempts, and
    afterwards refuse to testify against their
    captors. In system standards settings, S4 victims
    have been known to resist innovation and even
    refuse to compete against their competitors.
  • Recent incidents involving too much system
    standards attendance have resulted in people
    being captured by radical ITU-like factions known
    as the 3GPP or 3GPP2.
  • This leads to the following

The Future of Interconnection as seen by GSMA
(optional)
This is NOT the Internet
Note this
So much about IMS is NOT a Walled Garden
9
Who will pay for this?
  • The end-user the customer
  • Will he?
  • Not if he has a choice

10
A Reminder
  • The Internet is (or is intended to be) a network
    without central intelligence gt The stupid
    network (David S. Isenberg)
  • The Internet is based on the end-to-end principle
  • Every user may reach any other user via the IP
    address
  • All services may be offered anywhere and may be
    accessed from everywhere
  • This is of course also valid for voice and other
    communication services
  • VoIP (and other RTC services) is not necessarily
    a service, it is an application - so no service
    must be provided
  • Jon Peterson at the ITU-T/IETF NGN workshop in
    Geneva May 2005
  • If there is no service provided, you do not need
    a service provider either.

11
End Means End-User Customer
  • BTW, who cares about the customer in
    standardisation?
  • In standard bodies are only
  • manufacturers
  • providers
  • and since some time also regulators (funded by
    tax payers)
  • The last time I asked I got the answer from a
    telco we!
  • This approach led in the past to
  • e.g. ISDN, IN and ATM

12
What does the customers want?
  • (End-)users want connectivity via any device,
    anywhere, at anytime
  • global mobility
  • personal communication
  • global reachability
  • They also want
  • ease of use
  • fair prices
  • control over additional services
  • Skype is providing most of it, but it is also a
    walled garden

13
What Skype is not providing
  • It is not standards based (users dont care)
  • It does not provide connectivity (peering) with
    other providers via global identifiers
  • Current IETF activities
  • ENUM connectivity with E.164 phone numbers
  • SPEERMINT allow interconnect and peering
    policies between providers on the Internet
  • SIP P2P make SIP simpler and easier to use(and
    eventually make ENUM and SPEERMINT obsolete -)

14
SIP P2P plans to get rid of all optional boxes
Henry Sinnreich
  • DNS, ENUM?
  • SIP registrar and proxy servers,
  • Presence servers
  • Application servers
  • Announcements, voice mail, media servers,
    conference servers
  • Session border controllers
  • Softswitches Local switch emulation, PBX
  • Media servers
  • Network elements for QoS
  • Policy servers
  • Network management
  • Voice quality monitoring probes
  • Network engineering
  • System integration
  • VoIP network IT (OSS) systems for all the above

The sum of all IMS
.. and it wants to get rid of Skype

The War Is On
