Characteristics Of The IoA Network
" End-to-end IP, internet compliant (IETF, W3C, DMTF)
"
Enhancements where necessary to enable mobility. Design is based on ipv6
" Support end-to-end multi-media communication
over heterogeneous networks
" Use TCP/IP as a common framework for multimedia communication
" Enable global mobility
" Access over many different networks (wireless & wire line)
" Interworking with existing (legacy) networks
" Provisions for allocation and management of network resources
" Voice is only one possible application, although an important benchmark
Clear split between transport network and applications
