HARMONIZATION OVER NETWORKS
An overview

ETSI Project TIPHON

• Telecommunications and Internet Protocol
  Harmonization Over Networks
• The objective of this project is to support a
  market for voice communication and related
  multimedia aspects between users in IP based
  networks and users in switched circuit network
  (SCN), as well as between users in an SCN using
  IP based networks for connection/trunking between
  involved SCN, by the production of appropriate
  ETSI deliverables.

A new paradigm

• Old paradigms
• Circuit switching
• Packet routing
• New paradigm (TIPHON)
• Service provision
• Network technology independence

Standards activity

• VoIP - for commercial application
• Harmonisation of VoIP with VoSCN
• Order from Chaos

Areas of activity
8
Service, not technology

• Achieves homogeneity from heterogeneity
• Abstract design process
• Scaleable in concept
• Can be restricted in implementation

9
Why standardisation?

• Service providers want to be able to use products
  from different manufacturers in their networks.
• Manufacturers want to specialise on specific
  products (e.g. gateways, gatekeeper, clients,
  etherphones, ...)
• Standards are necessary for the interworking
  between administrative domains.
• Centralized and global services are necessary
  (clearing houses, certification authorities, the
  global Internet-Telephony directory service, ...)

10
Standards

• TIPHON
• aims to achieve interoperability using existing
  standards from open standards bodies
• harnesses the capabilities and momentum of other
  open standards bodies
• may develop new specifications if nothing
  currently exists to meet a requirement

11
Developing TIPHON

• Standards engineering principle
• Step 1 Requirements
• Step 2 Data and functional element
  identification
• Step 3 Protocol selection (or design)
• Formal and semi-formal analysis
• Use of SDL and UML with ASN.1

12
TIPHON product set

• Terminal equipment
• LAN phone, Etherphone, PC-phone
• Network termination
• Customer site or server site located
• Connection controller
• router control, switch matrix control
• Access controller
• Registration, authorisation, authentication

ETSI Bake - off

• A "bake-off" relates to a "baking contest,
  especially among amateur cooks, in which entries
  must be prepared and baked within a stipulated
  time".
• In the engineering world, bake-offs refer to
  events where engineers get together to test their
  implementations against each other.

UPCOMING EVENTS IPv6 Bake-off, 2-6 October.
(This week) VoIP Test Event on Speech Quality
starting 23 October. (TIPHON)

Past ETSI Bake - off

• ETSI, IMTC, Microsoft, Intel and Tenovis,
  supported by France Telecom, held the IMTC
  SuperOp! and TAPI Bake-off from 8 to 15 July 2000
  in Nice, France. Approximately 100 manufacturers
  of multimedia conferencing and telephony products
  were able to perform technical tests to evaluate
  the interoperability of their current and future
  products.
• This event showed that the initial teething pains
  of the products tested were definitely over and
  that the manufacturers involved are well on their
  way to attaining a higher level of quality in the
  near future.
• The next VoIP test event on Speech Quality that
  will take place staring on the 23rd October at
  the ETSI premises will surely interest the same
  manufactures.

• Open and independent
• To protocols
• To networks
• To technology
• Homogeneous
• From heterogeneous
