A Novel Management Information Retrieval Algorithm Based on NGI

It is increasingly a difficult problem how to decrease the usage of network resources by network management systems. Otherwise, the performance of network management is affected by the scheme to collect MIB (management information base) information. A novel algorithm - DGP (distributed group- prefetching algorithm) is put forward, which is used for retrieving MIB information from the managed devices in the management of CERNET2 (China Education and Research Network based on IPv6). DGP can adjust many little retrieving objects into one prefetching group to access, decrease the frequency of retrieval, and thus can use fewer network resources and decrease the network overhead without alteration of existing network management protocols.
