ETSI Project TIPHON
• ETSI - European Telecommunication Standards
Institute
• TIPHON - Telecommunications and Internet
Protocol Harmonization over Networks
• Started in May 1997 with short term goals to
standardize the H.323 gateway
• In 2000, refocused to develop the specifications
(protocol profiles and test suites) to enable end-to-end
telephony and multimedia communications services
over Next Generation Networks (NGN)

• each Domain may have its own commercial goals

Design principles (2)

A service is rendered in exchange for money.
– Services are explicitly requested and explicitly stopped, this
provides basis for charging
– Services are only delivered to authorized users
– Services are only sellable if QoS and security can be guarantee
 Dedicated VoIP infrastructure is expensive to maintain
– Only a converged (packet) network that supports multiple
services over one infrastructure can be commercially viable
 NGN will be deployed in an unbundled, open telecom
world
– Allow competition among SPs on something other than price
– Support hooks for value add

Design principles (3)
 Affordable multi-service architecture; Do not mix
application and transport!
 Support services for roaming users
 Support unique services
– Service provided from HOME service provider
 Service provider determines media route
–
–
–
–
Service may include in-band media events
Support for Lawful Intercept
Call Routing follows the money
QoS flows cost money so service providers will do least cost
routing on it (providing QoS can be met)
 Technologies come and go: Be technology independent

Development Process
• TIPHON Release Scheduling
– Identification of clearly understood and scoped set of requirements per release
•
Step A = Release definition
– Declaration of plan with the identification of the associated work items
•
Step B = Capabilities & Requirements
– Specification of Service Capabilities and Service Independent Requirements
•
Step C = Reference Architecture
– Definition of functional entities and related information flows, developed
independently of underlying technology issues
•
Step D = Implementation framework
– Definition of protocol-neutral framework together with identification of key
interfaces and definition of related “TIPHON Meta-protocol”
•
Step E = Technology mapping & Verification
– Mapping of TIPHON meta-protocols into supported technologies (e.g. H.323)
– Creation of PICS and related test suites for resulting protocol profiles
– Creation of interoperability test scenarios (e.g. H.323 - SIP)

Conclusion
•
•
•
•
TIPHON is not just Voice over IP
TIPHON enables new and differentiated services
TIPHON is technology agnostic
TIPHON specifies capabilities that can be used
to implement real services
– Not constrained to specific network technologies
– Enables Inter-domain Interoperability at transport
and service level
