Collect Algorithm and Optimization for SNMP-Based Data Collect Engine
SNMP数据采集引擎的采集算法及其优化

SNMP.based data collecting is fundamental for IP network management. This paper presents a SNMP. based Data Collect Algorithm for common use. According to requirement of data collecting, the algorithm disassembles collect tasks into metadata, and then reconstructs the protocol packet. Also takes full advantage of GetBulk operation, and brings out a combination algorithm for discrete variables of a MIB table so that the operation is optimized. A collect engine is implemented using the algorithm, which supports dynamic collection of multiple MIB variables, supports arithmetic computing and logical computing, supports threshold judgment and sends out abnormal events notifications. Tests are given to prove that the algorithm reduces the traffic for network management and improves the efficiency.
