With uploaded file path information built into the indexes, a tree-structure like vector space model...
This paper introduces the development of the existing SNMP, and the disadvantage of the current SNMP system. After that introduces the SNMP system that is designing and developing, the system can simultaneously support snmpv1. snmpv2c, snmpv3, and can be used in a mixed environment of ipv4/ipv6. This system in light of other similar system uses the LEAPS algorithm to judge the state of network, and...
