IPng Internet Protocol Next generation
The new version of IP protocol, formally known as IPV6. Main purpose is to work with the current version of IP (IPV4) co-exist, to cope with the increasing network (NETWORK) and host (HOST) The number and amount of data transfer. IPV6 CIDR encoding to use to allocate IP ADDRESS.
IPSec Internet Protocol Security
IPSec is the industry in network communications applications, the most widely used encryption and tunneling technology, but also without sacrificing security, under the premise of being chosen by the Internet Layer IP-VPN deployment method, especially for the Frame Relay or ATM can not afford the high cost of the SMEs, IPSec use nothing less than a gospel.
In the mobile workers and remote offices linked to by the IT department really control the corporate headquarters network hardware and software used on the IP VPN with IPSec-after all, a good tool for network traffic.
But for large enterprise users, extranet infrastructure construction are subject to more stringent review, because IPSec is still the lack of a traditional second-tier Internet service can provide the reliability and performance, for them, the distinction between quality and service level (CoS) was still more important than price factors alone.
IPSec VPN protection while providing high security, but when applied to large-scale deployment when the Extranet for the IT executives could still cause some practical difficulties. For example: IPSec link to objects and back-end transactions, vendor applications will be costly and extremely complex.
IPv4 & IPv6 (Internet Protocol version 4 & Internet Protocol version 6)
Fourth edition of Internet Protocol used for the current Internet addressing ways and agreements it to four bytes (4 Bytes) to addressing the world's office a connected to the Internet (Internet) computer. In recent years, the Internet and the rapid development of computers and the Internet surge, combined with the future of Mobile Internet (Mobile Internet) The Internet address of the terminal equipment to the needs and Borderless, IPv4 addresses will also be expected to 2005 - 2010 years, the use of depleted.
In response to the growing shortage of Internet addresses and Internet Safety (Security), mobility (Mobility), Management (Management) upper-related issues become increasingly complex, next-generation Internet Protocol is the sixth version of Internet Protocol (Internet Protocol version 6, IPv6) and so the formulation.
IPv6 as the Internet was developed and finalized in 1998, the organization of the next-generation Internet protocol standard, to 16 bytes (16 Bytes) of space to addressing any of the equipment connected to the Internet, enough to meet the coming decade, the Internet network Lu device IP address needs. Apart from enhancing the IPv6 addressing capabilities, and built-in automatic setting (Auto-configuration), Internet Security (IP Security, IPSec), and operational capacity to support (Mobile IP), can resolve the current IPv4 management, network security and mobility problems.
As more and more domestic and foreign academic institutions, Internet service providers (Internet Service Provider, ISP) for IPv6, the installation of his subordinates, and on-line services, is generally believed that IPv6 will gradually replace IPv4 as the next generation of Internet networks Road agreement. However, this conversion process will not be completed within the short term. |
