Abstract
The concept of Next Generation Network (NGN) was conceived around 1998 as an integrated solution to combine the quality and features of the PSTN with the low cost and routing flexibility of the Internet to provide a single infrastructure for the future public network. This carrier grade Internet solution calls for the creation of a consolidated, packet transport and switching infrastructure and the development of a flexible, open, software switch (softswitch) to handle voice telephony as well as multimedia services. Almost all the telecom equipment manufacturers as well as some Internet equipment vendors immediately subscribed to this vision and joined the race to create convergent products for the NGN market.
