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.
