Description
This issue of COMMUNICATIONS & STRATEGIES is a follow-up to the one published in March 2008 (1st quarter 2008, The challenges and opportunities of Next Generation Networks) which was devoted to the issues created by the deployment of new optical access networks. A review of next generation network rollout would not be complete if we limited ourselves to Next Generation Access, and neglected to examine the ways in which NGNs will interconnect. Interconnection has always been a central issue for telecommunications. It was the cornerstone of international cooperation in the sector and the basis of the competition policies put into place in the 1970s. The Internet long appeared to fall outside classic interconnection rules. The way that the "network of networks" operates has escaped the strict regulatory frameworks that govern fixed and mobile telephone networks. Peering and transit agreements among ISPs have emerged solely through market forces rather than through regulation. But the steady increase in Web 2.0 and peer-to-peer traffic, and the asymmetries between "eyeball access networks" and "content intensive networks" are putting pressure on traditional peering and transit models, leading to hybrid agreements. Added to this, the steady migration of applications such as voice calls on fixed and mobile networks to IP infrastructure brings a steady stream of questions over the desirability of maintaining a PSTN-style interconnection system, subject to billing principles such as "calling party's network pays". The continuing decrease in call termination tariffs on fixed networks will reduce the stakes for large fixed operators wishing to migrate to new charging models such as bill and keep. On mobile networks, however, wholesale call termination remains a significant source of revenue, making any migration to a different charging model difficult.
