基于MNSS的医院VTP倒灌防范方案研究及仿真

Research and Simulation on the Prevention Scheme of VTP Inversion in Hospital Based on MNSS

在大型的医院网络管理中,为节约开支,常使用VTP技术使多台交换机的配置信息保持同步,但由此带来的VTP倒灌会破坏医院网络的稳定性,带来不可估计的经济损失。针对这一问题,本文对VTP的工作原理、VTP的运行模式以及VTP倒灌现象进行深入研究,提出医院VTP倒灌防范方案,并且通过使用MNSS(Medical Network System simulator,医学网络系统虚拟仿真软件)对VTP倒灌及其抑制方案进行仿真实验研究。结果证明该方案能够有效避免VTP倒灌现象的产生,保持医院网络的稳定性。

In large hospital network management,in order to save money,VTP technology is often used to keep the configuration information of multiple switches in sync,but the resulting VTP backwater will destroy the stability of the hospital network and bring about the economic loss that can not be estimated.To solve this problem,in this paper,the working principle of VTP,the running mode of VTP and VTP intrusion phenomenon in-depth study,put forward the hospital VTP intrusion prevention programs,and through the use of MNSS（Medical Network System simulator,medical network system simulation software） and its suppression scheme pour irrigation on VTP simulation study.The results show that the scheme can effectively avoid the emergence of VTP inversion,and maintain the stability of the hospital network.
