Improved Model of SNMPv3 Supporting Multicast
Sui Zong-jian · 2012
With the development of triple play,the type of business increases and the number of devices increases dramatically.Some problems,such as the data repeat sending,large broadband overhead and low efficiency,are more serious in typical SNMP network management system based on unicast mode.An improved SNMPv3 model supporting multicast was proposed and the concepts of multicast group and the entity of group proxy were introduced.In the improved SNMPv3 model,the definition of MIB was extended and the SNMP engine was improved to identify and process the multicast messages.The improved model and main modules on management stations and proxies were given respectively.Then the implementation flows of group management and data collection based on improved model were described.The test results for the prototype system show that the data collection based on multicast polling can save the resource of senders,reduce network traffic and improve the data query and data collection efficiency greatly.
