　　【解析】SNMP(簡單網(wǎng)絡管理協(xié)議)的關鍵是其簡單的特性，它有一個很小的功能集，利用它來從任何網(wǎng)絡設備收集信息。在SNMP環(huán)境下，幾乎所有的工作都是由網(wǎng)絡管理系統(tǒng)來處理的。那些被管理的設備并沒有因為處理花費而增加負擔，而這些花費可能影響到它們的性能。

　　【解析】簡單網(wǎng)絡管理協(xié)議(SNMP)是一種傳輸層的協(xié)議，利用它可以在不同的網(wǎng)絡設備之間交換管理信息。它是TCP/IP協(xié)議簇的一部分。SNMP使網(wǎng)絡管理員能夠管理網(wǎng)絡的性能，發(fā)現(xiàn)和解決網(wǎng)絡中的問題并為網(wǎng)絡網(wǎng)絡擴張作規(guī)劃。一個SNMP管理網(wǎng)絡包括三個主要組件：管理設備，代理和網(wǎng)絡管理系統(tǒng)。
