Internet & NGN, Interconnection practices & principles
As the impact of "all-IP" and changes in browsing habits increases, the internet is having to manage an ever-growing stream of traffic, with varying QoS restraints, and to handle sizeable asymmetries in traffic flow. These changes naturally hold consequences for the interconnection practices that are the very basis of how the network of networks operates, and so give rise to a first series of questions: 丒What are internet players丒current interconnection practices (ISPs, backbone operators, application hosts, etc.)? 丒How is the role played by peering and transit agreements likely to evolve? 丒Under what circumstances might NRAs be called upon to intervene? Nevertheless, the fact that the shift to all-IP will take place gradually 丒and continue to coexist with markets operating on traditional networks 丒gives rise to a second series of questions: 丒How to manage NRAs丒highly controlled regulatory practices, which govern classic telephony and cellular network interconnection, with the cooperative and self-regulation principles that dominate the web? 丒How long should current SMP operator obligations be maintained? 丒What are the likely consequences for the competition environment in the fixed and mobile telephony markets? Meanwhile, telcos have rolled out a model for Next Generation Networks (NGN) along with a model for a services interoperability platform using IP Multimedia Subsystems (IMS). The plan for the migration to all-IP that emerges from these models and their implementation naturally goes beyond interconnection at the transport level, and beyond traditional methods of outsourcing intelligence to the edges of the network on internet players丒servers. And so a third series of questions arises: 丒How to define the different QoS levels in interconnection agreements? 丒How to defend this view of things or the principle of interoperability (interconnection at the applications level) without it being assimilated with discriminatory practices that run counter to the principle of net neutrality?
