IPv6: expansion of report IP

Job on expansion of report IP has been started in 1992. Necessity of it it was dictated to those, that practically all resources of the old version of report IP (IPv4) have been exhausted{settled}.

Fast growth of network Internet has led to to occurrence of deficiency of IP-addresses. The increased traffic started to cause overloads of the main routers. Character of the transmitted traffic has changed also. In him the multimedia data began to borrow{occupy} the increasing share.

The new version of report IP - version 6 (IPv6) - has been accepted by organization IETF in 1995. She is described in document RFC 1752.

Standard IPv6 will allow to create practically unlimited (if to be more exact, that 3,4 kh 1038) quantity{amount} of IP-addresses as the length of the address will increase with 32 up to 128 bats.

Because of predicted deficiency of IP-addresses (the maximum quantity in 4,3 billion as predict, it will be already achieved in 2007) in working report IPv4 mass transition on IPv6 is expected in 2007. The new standard will allow to appropriate{give} IP-addresses to set of devices - from household aplliances up to automobiles, systems of safety and identification maps, providing an opportunity of remote control by all this equipment.

The circuit of addressing IPv6 essentially differs from the circuit of addressing of report IP. Addresses of the addressee and the sender in report IPv6 are set by 128 bats. Such length of address space allows to remove{take off} for enough big period of time a problem of deficiency of addresses in network Internet.

The basic mechanism incorporated in the circuit of addressing of report IPv6, introduction of hierarchical division of address space on levels is. Instead of former two levels - numbers{rooms} of a network and number{room} of the device, - in report IPv6 it is used five levels, including two levels of identification of providers and three levels of identification of subscribers in a network.

Now Japan, China and South Korea negotiate for teamwork above introduction of the Internet - report of following generation IPv6, aspiring to intercept at the USA a palm of superiority{championship} in an establishment of global standards in this sphere. Amerikanskoie the companies dominate now over the market of routers. The majority of modern routers work on the basis of report IPv4. However the address space given by this report, will soon cease to suffice, if the number of sites of the Internet will grow so high rates.

Companies Nippon Telegraph will take part in the new project and Telephone Corp., Hitachi, Fujitsu, NES and Matsushita Electric. Together with them Korean companies Korea Telecom will participate in development and Samsung and some Chinese companies also, switching China Telecommunications.
