Foreword This Technical Report (TR) has been produced by ETSI Project Telecommunications

33、and Internet Protocol Harmonization Over Networks (TIPHON). ETSI 7 ETSI TR 102 129 VI .I .I (2003-01) 1 Scope The objective of ETSI Project TIPHON is the specification of interoperability mechanisms and related parameters to enable multimedia communications (particularly voice) to take place, to a d

34、efiied quality of service, between Switched Circuit Networks (SCN) and Internet Protocol (IP) based networks and their associated terminal equipment. The present document presents an overview of the architecture, protocols, QoS and security concepts for the interworking between TIPHON and IPCablecom

35、 systems. It introduces a possible framework for convergence between TIPHON and IPCablecom. Annexes A and B give a general overview of IPCablecom and TIPHON. Annex C addresses architectural issues for interworking between TIPHON and IPCablecom systems. Annex D provides information on the protocol as

36、pects relating to TIPHON and IPCablecom system interworking. Annex E examines TIPHON and IPCablecom QoS Policies, architectures and the control of network resources Annex F reviews TIPHON and IPCablecom security policies and describes the results of a threat analysis. 2 Re fe re nces For the purpose
