深信服AD設(shè)備緩存功能可降低用戶訪問對后臺服務(wù)器的負(fù)載壓力，在減少了后臺服務(wù)器投資成本的同時，提高了系統(tǒng)的處理能力和用戶的訪問體驗。 </p> <p> <br /> </p> <p>

無論是面向多數(shù)據(jù)中心的全局訪問調(diào)度，還是針對多鏈路和服務(wù)器群的負(fù)載均衡，深信服AD設(shè)備都扮演著一個關(guān)鍵的控制節(jié)點角色，其設(shè)備的穩(wěn)定性和安全性則直接影響到業(yè)務(wù)交付網(wǎng)絡(luò)的可用性。為了避**點故障的問題，采用雙機熱備是保證業(yè)務(wù)連續(xù)性的一種有效解決方案，能夠在很大程度上避免了網(wǎng)絡(luò)業(yè)務(wù)的中斷。 </p> <p> <br /> </p> <p> 兩臺深信服AD設(shè)備部署在網(wǎng)絡(luò)中，在此種模式下通常把正在執(zhí)行負(fù)載均衡調(diào)度的AD設(shè)備稱為主機，而另一臺處于待命狀態(tài)的AD設(shè)備則稱為備機。主機在處理業(yè)務(wù)的同時，會將業(yè)務(wù)產(chǎn)生的會話信息同步到備機，從而確保雙機切換后，新發(fā)起的業(yè)務(wù)訪問能繼續(xù)得到響應(yīng)處理，當(dāng)前正在進行的業(yè)務(wù)訪問也不會因此而中斷。此種模式適合于大多數(shù)網(wǎng)絡(luò)環(huán)境中避**點故障的部署需求。北京深信服負(fù)載均衡是什么各條鏈路的帶寬存在差異，并且不同用戶發(fā)起的連接保存時長差異較大。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="北京硬盤負(fù)載均衡品牌,負(fù)載均衡"

通過深信服AD設(shè)備的會話保持技術(shù)，可以為訪問用戶選擇曾連接上的特定服務(wù)器，實現(xiàn)無縫地處理用戶請求；另一方面可以減少新建連接的數(shù)量，有助于減小負(fù)載均衡設(shè)備的系統(tǒng)開銷。基于Source IP的會話保持機制－也被稱為基于簡單會話保持，是指深信服AD設(shè)備在作負(fù)載均衡時是根據(jù)訪問請求的源地址作為判斷關(guān)聯(lián)會話的依據(jù)，對來自同一IP地址的所有訪問請求在做負(fù)載均時都會被保持到一臺服務(wù)器上去。另外一個很重要的參數(shù)就是連接超時值，AD設(shè)備會為每一個進行會話保持的會話設(shè)定一個時間值，從一個會話上一次完成到這個會話下次再來之前的間隔如果小于這個超時值，AD設(shè)備會將新的連接進行會話保持，但如果這個間隔大于該超時值，AD會將新來的連接認(rèn)為是新的會話然后進行負(fù)載均衡調(diào)度， </p><p> <br /> </p> <p> <br /> </p> <p> 傳統(tǒng)TCP協(xié)議是基于局域網(wǎng)設(shè)計，一旦運用到互聯(lián)網(wǎng)這種不穩(wěn)定環(huán)境中的時候，就會使得數(shù)據(jù)的傳輸效率降低，特別在延時比較大、有丟包的時候尤為明顯。單邊加速技術(shù)通過對擁塞算法做優(yōu)化處理，解決一些TCP協(xié)議本身的缺點，以實現(xiàn)加速的效果；其**部分是對擁塞算法做優(yōu)化，如慢啟動，擁塞避免，快速重傳，快速恢復(fù)等。 </p> <p> ? 擁塞避免－能夠快速的準(zhǔn)確的預(yù)估出網(wǎng)絡(luò)中可用帶寬，并根據(jù)估計值確定擁塞避免窗口，從而比較大限度的利用網(wǎng)絡(luò)帶寬。 </p> <p> ? 快速重傳－允許接收端通過使用 SACK TCP 選項指示**多四個接收數(shù)據(jù)的非鄰接塊。RFC 2883 定義用于確認(rèn)重復(fù)的數(shù)據(jù)包的 SACK TCP 選項中的字段的額外使用。發(fā)送端可以通過此操作確定何時重傳了不必要的段并調(diào)整其行為，以防今后不必要的重傳。發(fā)送的重傳越少，整體吞吐量越合理。在多鏈路負(fù)載均衡的場景中，深信服AD設(shè)備通過訪問端的地理位置，鏈路隸屬的運營商。</p><div
