Implementation of accounting model within SNMPv3 architecture

This paper presents an implementation of a new accounting model within the existing SNMPv3 architecture. The model discussed is based on the SNMPv3 structure defined in RFC 2570-2575. This model defines accounting functionality, which is a result of the growth of importance of the SNMP and its wide usage. We assume that this will be one of the steps to improve and upgrade SNMP to answer the modern requirements. The accounting mechanism is an addition to the authentication and authorization functionalities that are already implemented in SNMPv3 by using the USM (user-based security model) and VACM (view-based access control model). This model provides minimal structure modification of the existing SNMPv3 architecture.
