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: �EWhat are internet players�Ecurrent interconnection practices (ISPs, backbone operators, application hosts, etc.)? �EHow is the role played by peering and transit agreements likely to evolve? �EUnder what circumstances might NRAs be called upon to intervene? Nevertheless, the fact that the shift to all-IP will take place gradually �Eand continue to coexist with markets operating on traditional networks �Egives rise to a second series of questions: �EHow to manage NRAs�Ehighly controlled regulatory practices, which govern classic telephony and cellular network interconnection, with the cooperative and self-regulation principles that dominate the web? �EHow long should current SMP operator obligations be maintained? �EWhat 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�Eservers. And so a third series of questions arises: �EHow to define the different QoS levels in interconnection agreements? �EHow 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?
