Embodiment Construction

[0084] The index service device, service resource address acquisition system and method in the same-root multi-layer NAT network provided by the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0085]In the traditional Internet, service resources are generally only deployed in the public network. In the same-root multi-layer NAT network, service resources can be deployed in the first layer, second layer, and third layer along the connection relationship of the private network. The same-root multi-layer NAT network can not only expand the number of user access, but also expand the scope of deployment of service resources. According to the physical connection relationship, when users use network services, they should be able to directly access the service resources deployed in the network controlled by each layer of NAT devices, not just the service resources deployed in the public network. In this way, it ...

Abstract

The invention discloses a system and a method for a service resource address access system in a same-rooted multilayer NAT network. By arranging an index service device in the multilayer NAT network, mappings of a service resource in private network in the multilayer NAT network are established, the service resource is registered in the index service device, a client makes a query based on the index service device about the service resource, and makes use of the service resource in private network. By this invention, in a server-client network, a server can not only be arranged in a public network, but also a multi-level private network; the service quality of transmission is improved, and the demand pressure of public network address and data transmission ability is lowered.

Description

technical field [0001] The present invention relates to the technical field of computer network communication, and more specifically, the present invention relates to a system and method for acquiring service resource addresses in a same-root multi-layer NAT network. Background technique [0002] At present, the IPv4-based Internet address space is insufficient to meet the needs of many users for network access, especially for countries such as my country with large network requirements and insufficient address allocation, the problem of insufficient space is more prominent. From the perspective of actual application and deployment, Network Address Translation (NAT) technology is an effective method for Internet users to access the Internet when Internet IP (Internet Protocol) addresses are insufficient. [0003] NAT is a standard of the Internet Engineering Task Force (IETF), which allows an entire organization to appear on the Internet with a public IP address, and convert...
