An Improved Error Handling Method in SNMPv2 Protocol Operations

SNMPv1 is very successful due to its simplicity,flexibility, and extensibility. However, simplicity can also be adrawback. In SNMPv1, a manager can only retrieve one piece ofinformation at a time, and an agent merely reports one error to itsmanager, though there may be several errors having occurred during theprotocol operation. These two interactions enlarge the number ofprotocol exchanges between a manager and an agent. SNMPv2 permits theretrieval of large data blocks, but the errors can only be handled oneby one. These errors continually occur in a multivendor network. Thispaper proposes an error handling method in SNMPv2 protocol operations.In this method, all errors within a received PDU can be detected by theagent simultaneously.
