Embodiment Construction

[0107] The principle and features of this solution will be described below in conjunction with the accompanying drawings, and the examples given are only used to explain this solution, not to limit the scope of this solution. For those of ordinary skill in the art, all embodiments obtained according to the spirit of this scheme, without making creative efforts, belong to the protection scope of this scheme.

[0108] This embodiment of the solution is applicable to a system architecture in which various types of networks are jointly established. In this system architecture, there is no clear intervening relationship when various types of networks are built, and their internal network addresses can be set independently. Each type of network can be connected through address translation equipment.

[0109] It consists of virtual private network (for example, VPC, etc.), private network (for example, according to the coverage, it can be divided into LAN and WAN, etc., and accordin...

Abstract

An embodiment of the invention provides a data transmission method applied to the field of communication technology. According to the invention, specific setting is performed on the addresses of server providing services, so that a user in a virtual private network can acquire services provided by the corresponding servers only with the private network capable of providing services and the user inthe virtual private network does not need to acquires services through accessing other network except the private network. Therefore, traffic is saved for the user.

Description

technical field [0001] The solution relates to the communication field, in particular to a data transmission method and network equipment. Background technique [0002] In a VPC (virtual private cloud, virtual private cloud) network, the address of each user in the network can be customized within the address range within the relevant specifications. Since the address space in the VPC is freely planned by the user and the address resources are freely controlled by the user, cloud service providers will avoid randomly invading the user's address space in the VPC by occupying the network address in the VPC. In this case, the cloud service provider cannot provide users with certain services, especially basic services such as NTP (Network Time Protocol, Network Time Protocol), by setting a unified IP address inside the VPC network. [0003] At present, in order to provide the aforementioned basic services, server providers generally require users to obtain various basic service...
