Problems solved by technology

National border identification needs to superimpose traceroute detection information of measurement source points in different locations, but there is no concept of geographical location and boundary at the network layer in the TCP / IP architecture; and in measurement sampling, sampling deviation affects the accuracy of inference

specific Embodiment approach 1

[0070] Specific implementation mode one: as Figures 1 to 2 As shown, this embodiment provides the following description for the realization of the identification method or system of the Chinese network border:

[0071] To achieve this, the system is divided into four modules:

[0072] (1) Data labeling

[0073] (2) Data screening

[0074] (3) Gateway extraction

[0075] (4) Gateway verification

[0076] The input is the Traceroute data set from the detection point to the target IP address node, and the output is the gateway IP address set. For the input Traceroute data set, first mark each attribute of the IP address in each data, then remove the wrong Traceroute data, extract the gateway IP address from the remaining data through each attribute vote, and finally check the accuracy of these gateway IP addresses authenticating.

[0077] The specific implementation steps of the module (1) are (1.1) extract the IP address in each hop data from the Traceroute source data, a...

Embodiment

[0113] In order to describe the present invention more specifically, technical scheme of the present invention is described in detail below by example:

[0114] The object of this system test is a series of Traceroute source data measured by monitoring points, the format is as follows:

[0115]

[0116] It contains the monitoring point, destination IP address and Traceroute node information. Extract the IP address of each hop, and query each attribute in a unified manner: the source data contains RTT information, no need to query; obtain AS number and country information by querying the BGP database; query reverse domain name information through the "dig-x IP" command; The database IP2Location query country, region, city information; query organization information (org, netname, etc.) through the "whois IP" command; Ping the same target IP address through multiple monitoring points, take out the monitoring point information with the smallest delay, and the measured The res...

Abstract

A method and system for identifying Chinese network borders, relating to the technical field of network resource surveying and mapping. The purpose of the present invention is to identify the Chinese gateway IP address, which can identify the gateway IP address for each path passing through the national gateway, and can accurately identify which IP address in the path is the gateway IP address. The method of the present invention includes a data labeling process: obtaining a Traceroute data set marked with an IP address attribute; a data screening process: obtaining the Traceroute data after screening and storing marks respectively according to the destination IP address; gateway extraction process: extracting a candidate set, and passing through each node Each attribute selects the respective gateway IP address; gateway verification process: use the method of minimum delay verification or data cross verification method for gateway verification. The present invention integrates traceroute information and IP address obtainable information in the path, mutually restricts and promotes each other, and comprehensively identifies the national gateway IP address.

Description

technical field [0001] The invention relates to the technical field of network resource surveying and mapping, in particular to the identification of Chinese national border gateways. Background technique [0002] The reliability of some points in the Internet is particularly important, such as national border points, etc. If these points are attacked by DDOS, the consequences will be disastrous. Identifying Chinese gateway IP addresses is the basis for research on link congestion between China and other countries; identifying Chinese gateway IP addresses can more accurately construct Chinese network topology maps and network modeling, thereby analyzing network resilience and robustness and preventing attacks or disruptions Possibility of links; identifying the IP address of the Chinese gateway can more accurately map IP-to-locating, map the information of countries passing through the traceroute path, and have certain guiding significance for network connectivity and networ...
