Data center system and data center service providing method

Abstract

The invention provides a data center system. The data center system comprises a plurality of first network address translation devices, a plurality of second network address translation devices and a plurality of servers. The plurality of first network address translation devices are used for receiving a first service request of a client side, carrying out source address and destination address translation on the first service request according to a rule to generate a second service request, and forwarding the second service request to one of the plurality of second network address translation devices; the plurality of second network address translation devices are used for receiving the second service request forwarded by the first network address translation devices, translating the source address and the destination address to generate a third service request, and forwarding the third service request to the servers through an extranet; the plurality of servers are used for receiving the third service request forwarded by the plurality of second network address translation devices, generating a corresponding third network response, and returning back the third network response to the second network address translation devices. The data center system is succinct in network structure, easy to develop and transparent to users in use, can be expanded smoothly, and also has the characteristics of being efficient, accurate, easy to use and expandable. The invention also discloses a data center service providing method.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a data center system and a method for providing services by the data center. Background technique [0002] Address translation equipment NAT (Network Address Translation) is used in the case of shortage of IP addresses and isolation of internal and external networks in the data center. After the internal network user's request to access the external network server server reaches the NAT device, the private address of the internal network user will be converted into an external network address to communicate with the external network server. This mechanism improves the utilization rate of the external network IP and improves the security, but it also restricts the internal network users to access the external network only through the NAT device. In order to ensure that requests from intranet users to the external network can reach the NAT device, typically, the defau...

Problems solved by technology

[0007] (2) Complex deployment

When using IP tunnels, it is necessary to establish corresponding tunnels on user A and user B respectively, and configure rules, which is not convenient for large-scale deployment

[0008] (3) Opaque to users

[0009] (4) When using a tunnel, the user's needs cannot be distinguished, and all traffic of the user can only be selected to go through the tunnel

At this time, tunnel technology cannot meet the demand
