提出一种新的根据SNMP的拓扑主动发现算法,该算法可以完成以太网内部的交流机、主机互联的拓扑主动发现,从而降低根据以太网交流技能的园区网的网络办理难度。以太网是当时园区网所运用的首要网络技能,运用以太网交流机区分网段并完成网内互联。以太网通讯运用交流技能,数据交流双方依据MAC地址识别。在一个以太网内,每一台交流机都存储着网络内一切活动主机的MAC地址。运用SNMP协议可以获取交流机中MAC地址表数据,运用笔者所述算法处理这些数据可以完成以太网内部交流机、主机拓扑构造的主动发现。因为SNMP和MIB被各厂商所接受,因而笔者提出的算法具有通用性。关键字:SNMP;MIB;拓扑主动发现

(A new topology automatic discovery algorithm based on SNMP is proposed, which can realize the automatic topology discovery of the interconnection of switches and hosts within the Ethernet, thereby reducing the network management difficulty of the campus network based on the Ethernet communication technology. Ethernet is the primary network technology used in campus networks at the time, using Ethernet switches to distinguish network segments and complete intra-network interconnection. Ethernet communication uses communication technology, and both sides of data exchange are identified by MAC address. In an Ethernet, each switch stores the MAC addresses of all active hosts in the network. The MAC address table data in the switch can be obtained by using the SNMP protocol, and the active discovery of the topology structure of the switch and the host within the Ethernet can be accomplished by using the algorithm described by the author to process these data. Because SNMP and MIB are accepted by various manufacturers, the algorithm proposed by the author is universal. Keywords: SNMP; MIB; active topology discovery)
