Abstract

The invention provides a data center system, a data center device and a method for providing service. The data center system comprises a switch and a network address translation (NAT) device and a server which are connected with the switch, wherein the switch judges that a request message comes from the first category of network or the second category of network; if the request message comes from the first category of network, the switch transmits the request message to the server; if the request message comes from the second category of network, the switch transmits the request message to the NAT device; and the NAT device is used for receiving the request message which is transmitted by the switch, converting the request message to the request message of the first category of network and transmitting the request message the source address of which is mapped to the server by virtue of the switch. The embodiment of the invention can provide a flexible deployment way by virtue of the NAT device and is applicable to the deployment of a large-scale and complex data center system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data center system and device and a method for providing services. Background technique [0002] IPv6 (Internet Protocol Version 6, the sixth edition of the Internet Protocol) is the next-generation IP protocol used to replace the current version of the IP protocol - IPv4 (Internet Protocol Version 4, the fourth edition of the Internet Protocol). Compared with IPv4, IPv6 has advantages: larger address space, smaller routing table, enhanced multicast support and support for streaming, etc., has considerable development opportunities, and can provide a good network platform for quality of service control . Therefore, how to migrate existing IPv4 network data to IPv6 network is an important issue in current network service research. [0003] Traditional IPv4 / IPv6 network data migration methods include the following three: [0004] (1) Dual stack technology [00...
