Abstract

A communication processing apparatus is disclosed which performs a process for establishing a connection upon receipt of a communication connection request. The apparatus includes a controlling element for performing a connection availability determination process upon receipt of the connection request. The controlling element performs a user identification process for identifying a user representing a connection request sender based on data in the connection request. The controlling element further carries out the process for establishing the connection if communication processing resources allocated for the user having a user identifier acquired in the user identification process are judged to be available.

4. A communication processing apparatus according to claim 1, wherein said controlling means acquires in said user identification process at least either a sender IP address or a sender MAC address of said connection request as user information.

5. A communication processing apparatus according to claim 1, wherein said controlling means acquires in said user identification process a destination port number of said connection request as user information, and performs said process for establishing said connection if communication processing resources allocated for the acquired destination port number are judged to be available.

6. A communication processing apparatus according to claim 1, wherein said controlling means performs said process for establishing said connection by successively carrying out:

a user identification process for identifying the user corresponding to said connection request sender based on a user table which associates address information with user identifiers;

a resource use condition determination process for determining a resource use condition corresponding to said user based on a resource use condition table which associates said user identifiers with resource use conditions including resource area information; and

a resource area determination process for determining a connection-applicable resource area corresponding to said connection request sender based on a resource management information table which associates said resource area information with resource availability information.

7. A communication processing apparatus according to claim 1, wherein said controlling means performs said process for establishing said connection by successively carrying out:

a user identification process for identifying the user corresponding to said connection request sender based on a user table which associates address information with user identifiers;

a resource use condition determination process for determining a resource use condition corresponding to said user based on a resource use condition table which associates said user identifiers with resource use conditions including resource area information; and

a resource area determination process for determining a connection-applicable resource area corresponding to said connection request sender based on a resource management information table which associates said resource area information with resource availability information;

wherein said resource use condition table allocates more resource areas as resource use conditions for the user identifiers of users of higher priorities.

8. A communication processing apparatus according to claim 1, wherein said controlling means performs said process for establishing said connection by successively carrying out:

a user identification process for identifying the user corresponding to said connection request sender based on a user table which associates address information with user identifiers; and

a resource use condition determination process for searching a resource use condition table for an entry of any available connection based on user identification data acquired in said user identification process, said resource use condition table associating each of said user identifiers with a group identifier, a maximum connection count, and a current connection count.

9. A communication processing apparatus according to claim 1, wherein said controlling means performs said process for establishing said connection by successively carrying out:

a user identification process for identifying the user corresponding to said connection request sender based on a user table which associates address information with user identifiers; and

a resource use condition determination process for searching a resource use condition table for an entry of any available connection based on user identification data acquired in said user identification process, said resource use condition table associating each of said user identifiers with a group identifier, a maximum connection count, and a current connection count; and
