US 8,477,774 B2 · Method and system for detecting accessing host contained in network, and statistic and analyzing server

Abstract

A detecting method is provided, which includes extracting an Internet Protocol Identifier value from an obtained data packet. The detecting method may further include searching in a record table containing a correspondence relationship between an Internet Protocol Identifier value and a terminal serial number to determine whether the record table contains an adjacent Internet Protocol Identifier value smaller than the extracted Internet Protocol Identifier value and modifying the adjacent Internet Protocol Identifier value that is smaller than the extracted Internet Protocol Identifier value to be the extracted Internet Protocol Identifier value if the record table contains the adjacent Internet Protocol Identifier value smaller than the extracted Internet Protocol Identifier value. Otherwise, the detecting method may also include, adding a new record of the extracted Internet Protocol Identifier value and the corresponding terminal serial number into the record table. When a notification is received, the detecting method may calculate the number of terminal serial numbers in the record table and output the number of terminal serial numbers as the number of hosts. The provided detecting method may further provide a corresponding statistic and analyzing server and a detecting system.

Dependent claims

A method for detecting a host included in a network, comprising:

extracting an Internet Protocol Identifier value IPID1 from an obtained data packet;
searching in a record table containing a correspondence relationship between an Internet Protocol Identifier value and a terminal serial number to determine whether the record table contains an adjacent Internet Protocol Identifier value IPID2 smaller than the extracted Internet Protocol Identifier value IPID1;
modifying the adjacent Internet Protocol Identifier value IPID2 to be the Internet Protocol Identifier value IPID1 if the record table contains the adjacent Internet Protocol Identifier value IPID2 that is smaller than the extracted Internet Protocol Identifier value IPID1;
adding a new record of the Internet Protocol Identifier value IPID1 and the corresponding terminal serial number into the record table otherwise;
and
calculating a number of terminal serial numbers in the record table and outputting the number of terminal serial numbers as a number of hosts.

3 more elements

A statistic and analyzing server, characterized by comprising:

a table storing unit, configured to store a record table containing a correspondence relationship between an Internet Protocol Identifier value and a terminal serial number;
a first searching unit, configured to search in the record table stored in the table storing unit to determine whether the record table contains an adjacent Internet Protocol Identifier value smaller than an Internet Protocol Identifier value IPID1 extracted from an obtained data packet;
a first processing unit, configured to modify the adjacent Internet Protocol Identifier value smaller than the extracted Internet Protocol Identifier value IPID1 as the Internet Protocol Identifier value IPID1 if the first searching unit determines that the record table contains the adjacent Internet Protocol Identifier value smaller than the IPID1, and to add a new record of the IPID1 and a corresponding terminal serial number into the record table if the first searching unit determines that the record table contains no adjacent Internet Protocol Identifier value smaller than the Internet Protocol Identifier value IPID1;
and
a statistic unit configured to calculate a number of terminal serial numbers in the record table and to output the number of terminal serial numbers as a number of hosts.

2 more elements

A detecting system, comprising:

a separating and filtering server, configured to separate a data packet of a designated type from the received data packet, and to extract an Internet Protocol Identifier value IPID4 from the separated data packet;
and
a statistic and analyzing server, configured to search in a record table containing a correspondence relationship between an Internet Protocol Identifier value and a terminal serial number to determine whether the record table contains an adjacent Internet Protocol Identifier value smaller than the Internet Protocol Identifier value IPID4, to modify the adjacent Internet Protocol Identifier value smaller than the Internet Protocol Identifier value IPID4 as the Internet Protocol Identifier value IPID4 if the record table contains the adjacent Internet Protocol Identifier value smaller than the Internet Protocol Identifier value IPID4, to add a new record of the Internet Protocol Identifier value IPID4 and the corresponding terminal serial number into the record table otherwise, and to calculate the number of terminal serial numbers in the record table and to output the number of terminal serial numbers as a number of hosts.
