RRPP和STP在企业网中的优势对比及应用设计 摘要 在企业局域网中，广播风暴是经常发生的问题。发生后会大量消耗网络带宽，导致数据包无法正常地在网络中传送，从而导致数据的传送的停滞、数据包的丢失等一系列问题，甚至导致整个局域网的瘫痪。如今使用最为广泛的广播风暴预防措施是进行STP或RRPP的配置。预先破除网络中的环路，从根源上抑制广播风暴的形成。虽然STP与RRPP看似有着相同的破环功能，但是实现原理和实际应用上却有着很大的区别。本课题就是通过在eNSP模拟器上进行一系列的模拟，来对两种协议进行应用和对比，来探讨两种协议各自优势和最适用环境。 关键词：STP；RRPP；广播风暴；二层环路 RRPP and STP advantage contrast and application in enterprise network design ABSTRACT Is often occurred in the enterprise local area network (LAN), the broadcast storm problem.After will consume network bandwidth, which leads to the packets could not normally in the network transmission, which can lead to the stagnation of the data transmission, packet loss, and a series of problems, and even cause the whole local area network paralysis.Now the most widely used broadcast storm STP or RRPP configuration is through preventive measures.Break in the network loop in advance, inhibit the formation of the broadcast storm from the source.Although the STP and RRPP seem to have the same function of broken, but the implementation principle and the practical application has the very big difference.This topic is through a series of experiments on eNSP simulator, application and comparison to two kinds of agreement, their respective advantages to discuss two kinds of agreement and the applicable environment.
