There are many arguments that can be made against the ETNO proposal to import the international accounting-rate regime from voice telephony to the Internet. Here as a PDF is an argument about its impracticality from ISOC. ISOC also agrees with my main point that the ETNO proposals will result in the marginalization and exclusion of the developing countries, especially their poor who are just beginning to join the Internet economy: Because the bilateral model of sending-party-network-pays or “sender pays” that is common in traditional telephony or mobile-settlement systems does not readily accommodate the Internet’s multi-party transit network system, it cannot be mapped to the Internet as we know it. Simply said, retro-fitting a “sender pays” settlement regime to the Internet is not possible without extensive changes to the infrastructure of the global Internet. In addition, the “sender pays” model could adversely impact the technical and commercial environment in developing economies that need to grow their networks.
