3 . The packet communication device according to claim 1 , the processor further configured to execute a method comprising:

determining whether or not the IP address corresponding to a terminal identifier of the terminal has been changed according to a database storing the IP address and the terminal identifier; and

updating the application rule when the IP address has been changed.

4 . The packet communication device according to claim 1 , the processor further configured to execute a method comprising:

receiving the IP address corresponding to a terminal identifier of the terminal from a Dynamic Host Configuration Protocol server;

determining whether or not the IP address has been changed; and

updating the application rule when the IP address has been changed.

5 . The packet communication device according to claim 1 , the processor further configured to execute a method comprising:

acquiring the IP address of the terminal by snooping communication between a Dynamic Host Configuration Protocol server and the terminal;

determining whether or not the IP address has been changed; and

updating the application rule when the IP address has been changed.

6 . The packet communication device according to claim 1 , the processor further configured to execute a method comprising:

acquiring the IP address corresponding to a terminal identifier of the terminal using Reverse Address Resolution Protocol;

determining whether or not the IP address has been changed; and

updating the application rule when the IP address has been changed.

7 . A method for generating a rule for processing a packet, comprising:

distributing a packet received from a terminal to one or more paths for a packet communication;

acquiring an IP address of the terminal; and

generating an application rule for packet processing based on the IP address.

8 . A computer-readable non-transitory recording medium storing computer-executable program instructions that when executed by a processor cause a computer to execute a method comprising:

distributing a packet received from a terminal to one or more paths for a packet communication;

acquiring an IP address of the terminal; and

generating an application rule for packet processing based on the IP address.

9 . The packet communication device according to claim 2 , the processor further configured to execute a method comprising:

determining whether or not the IP address corresponding to a terminal identifier of the terminal has been changed according to a database storing the IP address and the terminal identifier; and

updating the application rule when the IP address has been changed.

10 . The method according to claim 7 , wherein the application rule for the packet processing includes is at least one of a routing rule, a filtering rule, or a traffic control rule to perform policy-based routing for the packets received from the terminal.

11 . The method according to claim 7 , further comprising:

determining whether or not the IP address corresponding to a terminal identifier of the terminal has been changed according to a database storing the IP address and the terminal identifier; and

updating the application rule when the IP address has been changed.

12 . The method according to claim 7 , further comprising:

receiving the IP address corresponding to a terminal identifier of the terminal from a Dynamic Host Configuration Protocol server;

determining whether or not the IP address has been changed; and

updating the application rule when the IP address has been changed.

13 . The method according to claim 7 , further comprising:

acquiring, based on snooping communication between a Dynamic Host Configuration Protocol server and the terminal, the IP address of the terminal;

determining whether or not the IP address has been changed; and

updating the application rule when the IP address has been changed.

14 . The method according to claim 7 , further comprising:

acquiring the IP address corresponding to a terminal identifier of the terminal using Reverse Address Resolution Protocol;

determining whether or not the IP address has been changed; and

updating the application rule when the IP address has been changed.

15 . The method according to claim 10 , further comprising:

determining whether or not the IP address corresponding to a terminal identifier of the terminal has been changed according to a database storing the IP address and the terminal identifier; and

updating the application rule when the IP address has been changed.

16 . The computer-readable non-transitory recording medium according to claim 8 , wherein the application rule for the packet processing includes is at least one of a routing rule, a filtering rule, or a traffic control rule to perform policy-based routing for the packets received from the terminal.

17 . The computer-readable non-transitory recording medium according to claim 8 , the computer-executable program instructions when executed further cause the computer to execute a method comprising:

determining whether or not the IP address corresponding to a terminal identifier of the terminal has been changed according to a database storing the IP address and the terminal identifier; and

updating the application rule when the IP address has been changed.

18 . The computer-readable non-transitory recording medium according to claim 8 , the computer-executable program instructions when executed further cause the computer to execute a method comprising:

receiving the IP address corresponding to a terminal identifier of the terminal from a Dynamic Host Configuration Protocol server;

determining whether or not the IP address has been changed; and

updating the application rule when the IP address has been changed.

19 . The computer-readable non-transitory recording medium according to claim 8 , the computer-executable program instructions when executed further cause the computer to execute a method comprising:

acquiring, based on snooping communication between a Dynamic Host Configuration Protocol server and the terminal, the IP address of the terminal;

determining whether or not the IP address has been changed; and

updating the application rule when the IP address has been changed.

20 . The computer-readable non-transitory recording medium according to claim 8 , the computer-executable program instructions when executed further cause the computer to execute a method comprising:

acquiring the IP address corresponding to a terminal identifier of the terminal using Reverse Address Resolution Protocol;

determining whether or not the IP address has been changed; and

updating the application rule when the IP address has been changed.
