摘要
根据数据灾备中心特定网络环境的工作特点——网络必须具有高可靠性,并能及时发现设备故障,因此对拓扑算法就有高准确性和高效率的要求,针对现有拓扑算法在发现完整性和发现效率上的不足,提出了结合ARP与SNMP各自的优点,并采用多线程并行技术提高拓扑效率,给出了算法的设计与实现。实践证明,该算法在拓扑效率上提高了近一倍。
According to the features of a specific network environment of the disaster recovery data centerthe network must have high reliability and detect failure in time,for the lack of the existing topology discovery algorithm on efficiency and integrality,this paper combines the advantages of ARP and SNMP and adopt the multi-threaded parallel technology to improve the efficiency of topology,then design and implement the algorithm.The result shows that the efficiency of topology algorithm has almost doubled.
