NQA實(shí)驗(yàn)實(shí)例演示

NQA(Network?Quality?Analysis),即網(wǎng)絡(luò)質(zhì)量分析系統(tǒng),是一種實(shí)時(shí)的網(wǎng)絡(luò)性能探測和統(tǒng)計(jì)技術(shù)。利用NQA可實(shí)現(xiàn)對網(wǎng)絡(luò)運(yùn)行狀況的準(zhǔn)確測試,輸出統(tǒng)計(jì)信息,監(jiān)測網(wǎng)絡(luò)上運(yùn)行的多種協(xié)議的性能,等等?,F(xiàn)在聯(lián)華世紀(jì)將為大家進(jìn)行NQA實(shí)驗(yàn)的實(shí)例演示:

測試

?
?
斷開R1至LSW1的線路,測試NQA

?
斷開時(shí),PC1到R3中斷,再PING時(shí)已經(jīng)切換好路由。

?
恢復(fù)線路后,測試

?
路由還未切回主線。

?
再次等待15s左右,路由切換回主線。
