The telecommunications industry has embraced the Internet Protocol (IP) as the vehicle for the new worldwide communication infrastructures. This is evident in the movement of the new wireless and wire-line sectors towards a replacement of the PSTN, the increasing penetration of new Internet services (VoIP, IPTV) and the directions being taken in the 3G and 4G wireless businesses.
The main barrier to a fuller-scale deployment is the lack of predictable support for QoS, when packets have to cross many domains. The pace of investigation into this topic is increasing, and the objective of OpenNet is to involve Europe more strongly in the discussions towards finding a solution. The project will focus on defining world-wide the QoS parameter values for Premium IP services on the key interfaces between the market players in a Premium Internet environment. These are the Client-Network Interface (CNI) and the Inter-Carrier Interface (ICI).
The technical approach is to bring together the major Internet router manufacturers worldwide (Cisco, Juniper) and to organise workshops together with other parties, especially from the worldwide IPSphere Initiative, in order to agree the parameters and values that are appropriate for the multiple services that are carried across these interfaces. The benefit will be the avoidance of the current situation where every ISP has to make individual interconnection contracts with its peers, which will often be using incompatible bundles of QoS definitions for delay, delay variation and loss.
This existing scheme is not scalable, and impossible to use to manage end to end QoS when several domains are crossed. The output will be reflected in Internet Drafts. It is only with such a specification that ISPs can be confident of offering their customers Premium Services end-to-end across multiple networks. The work will also complement the following recommendations from ITU: G.1010 Y.1540 Y.1541.
