Development of 3G network and consumption growth of data services led to significant increase in number of the new devices connected to the Internet, and exponential growth of number of simultaneous subscriber sessions. At the same time each user at connection to worldwide network needs to provide the IP address for its identification - the unique network address of the device in the network built under the IP protocol. In a case with the mobile Internet the dynamic IP addresses are used, i.e. at each connection to the subscriber the new temporary address is selected. In the absence of the free address connection to the Internet is impossible.
Now in Russia the protocol of the IP addresses IPv4 at which each IP address represents a combination from four numbers, for example is used: 192.168.0.1. The quantity of the addresses at such system is limited: around the world there are 4.3 billion addresses within IPv4 protocol. In 30 years a global system the Internet exhausted a stock of the available addresses based on IPv4 protocol, and transition to addressing of new generation - IPv6 protocol which will allow to expand considerably a range of the available addresses due to increase in length of the address is planned in the nearest future.
The system of broadcast of the addresses Cisco Carrier Grade Network Address Translation (NAT) implemented by MTS gives a connectivity of new users to a global network the Internet at deficit of the public IP addresses due to simultaneous use of one address by several subscribers. Capability of a system to increase the performance to 80 million address broadcastings an opportunity to centralize Internet access for several regional networks of both mobile, and fixed connection will provide MTS. At the first stage the Cisco Carrier Grade Network Address Translation (NAT) system is installed in Siberia. Further implementing solution is planned in all regions of the country.
"Development of the mobile and fixed Internet and also emergence of the smartphones which are automatically connected to network for downloading of updatings of applications resulted in the serious shortage of the IP addresses. Estimates of specialists come down to the fact that in 2011-2012 the value of addresses IPv4 will be completely exhausted. In the nearest future this problem will become obvious not only to experts, but also normal Internet users who if in advance not to solve this problem, "will stand in a queue" behind the IP address to be connected to the Internet. Implementation of Cisco Carrier Grade NAT will provide transition to IPv6 protocol, smooth and imperceptible for subscribers of MTS. According to forecasts of experts, there will be enough stock of the addresses within this protocol still a minimum for ten-twenty years. Thus, for our subscribers the impossibility of Internet connection due to the lack of the free address will become simply excluded for many decades ahead", - Alexander Solovenchuk, the director of the macroregion noted Siberia.
Capacity of Cisco CRS-3 reaches 322 Tbit / with that is three times higher, than at the previous system of operator routing. It allows in a second with small to load all printing information of Library of Congress of the USA, to provide simultaneous video conference for all population of China and less than in four minutes to transfer via the Internet all movies created for all history of mankind.
"The router of the operator class Cisco CRS-3 is a basis for the Internet of new generation, its implementation will allow MTS company to set speed for fast distribution of video technologies, mobile devices of high-speed Internet access and new on-line services within this decade. It also opens opportunities for construction of more large-scale and effective networks", - the technical director of Cisco in Russia Kuzmich Andrey emphasized.
