NETWORK COMMUNICATION METHOD, NETWORK COMMUNICATION SYSTEM, NETWORK COMMUNICATION APPARATUS AND PROGRAM THEREFOR
First Claim
1. A method for network communication between a first device and a second device connected each other via a network under Simple Network Management Protocol, the method comprising:
- producing an access request when the first device accesses management information stored in the second device, the request containing additional information including at least one of identification information of the first device and identification information of a user of the first device in a value field for storing value data of a target device and included in a data field together with an identifier field for storing identification information of the target device;
transmitting the access request to the second device; and
permitting the transmitted access request so that the number of devices or users accessing the second device may not exceed a predetermined number on the basis of the identification information of the first device and/or the user contained in the transmitted access request and identification information of a device and/or a user accessing the management information.

Abstract
A method for network communication under SNMP includes: producing an access request when a first device accesses management information stored in a second device, the request containing additional information including identification information of the first device or identification information of a user of the first device in a value field included in a data field that contains an identifier field and the value field; transmitting the access request to the second device; and permitting the transmitted access request so that the number of devices or users accessing the second device may not exceed a predetermined number on the basis of the identification information of the first device or the user contained in the transmitted access request and identification information of a device or a user accessing the management information.

8. A network communication system, comprising:
-
a first device; and a second device connected to the first device via a network under Simple Network Management Protocol, wherein the first device produces an access request when the first device accesses management information stored in the second device, the request containing additional information including at least one of identification information of the first device and identification information of a user of the first device in a value field for storing value data of a target device and included in a data field together with an identifier field for storing identification information of the target device; and
transmits the access request to the second device; andthe second device permits the transmitted access request so that the number of devices or users accessing the second device may not exceed a predetermined number on the basis of the identification information of the first device and/or the user contained in the transmitted access request and identification information of a device and/or a user accessing the management information.

9. A network communication apparatus communicating with a device connected each other via a network under Simple Network Management Protocol, wherein
the network communication apparatus produces an access request when the communication apparatus accesses management information stored in the device, the request containing additional information including at least one of identification information of the communication apparatus and identification information of a user of the communication apparatus in a value field for storing value data of a target device and included in a data field together with an identifier field for storing identification information of the target device; - and transmits the access request to the device; and
when the communication apparatus receives an access request similar to the access request having been transmitted,the network communication apparatus permits the transmitted access request so that the number of devices or users accessing the communication apparatus may not exceed a predetermined number on the basis of the identification information of the device and/or the user contained in the transmitted access request and identification information of a device and/or a user in the device accessing the management information of the apparatus.
- and transmits the access request to the device; and
