Abstract: Systems and methods are provided for use in a Simple Network Management Protocol (“SNMP”) computing environment, by which efficiency of computing systems employing SNMP may be improved. An SNMP message is parsed, and the parsed information used to construct a binary tree. By using a binary tree, which is a data object that consumes less memory resources, efficiency of interactions between elements of the SNMP computing environment are improved. A method can include receiving a SNMP request for data. Then, the SNMP request is parsed and a binary tree constructed from the parsed SNMP request. The binary tree includes a plurality of type-length-value nodes. The length value of each non-leaf node is the summation of the length values of all the child nodes below the non-leaf node; and the length value of each leaf node is the length of the data requested.
