被動式冗余主要由服務(wù)的請求者實(shí)現(xiàn)，基于失敗重試原理，在可用的服務(wù)提供者之間重試，直到找到一個可用的提供者。被動式冗余是簡單的，但也有很大的局限性，它要求冗余節(jié)點(diǎn)只是作為信息的處理者，完全作為C/S架構(gòu)中的S，而不可能作為信息的發(fā)起者。這類冗余在事務(wù)處理系統(tǒng)（MIS）中比較常見，因?yàn)檫@類系統(tǒng)總是響應(yīng)用戶的操作，而很少會有自動收集信息并處理的業(yè)務(wù)。
在控制系統(tǒng)中的冗余架構(gòu)，基本都是主動式冗余架構(gòu)。它要求冗余節(jié)點(diǎn)能夠自動檢查主備節(jié)點(diǎn)的運(yùn)行狀態(tài)，并且在主節(jié)點(diǎn)失敗時自動切換到備節(jié)點(diǎn)。
主動冗余架構(gòu)也有兩種實(shí)現(xiàn)方式，一是主備節(jié)點(diǎn)間設(shè)有交換運(yùn)行狀態(tài)的通訊通道，由他們自行協(xié)商何時進(jìn)行主備切換，可以稱為自控方式。另一種是基于一個中心的冗余控制器，冗余控制器分別與主備節(jié)點(diǎn)通訊，并決定何時進(jìn)行主備切換，可以稱為集控方式。
在筆者參與的地鐵控制系統(tǒng)中，兩個與硬件直接通訊的主備RTU(REMOTE TERMINAL UNIT)之間就采用自控方式。當(dāng)兩個RTU之間不能通訊時，或者當(dāng)前系統(tǒng)中僅有一個RTU時，它們會將自己設(shè)定為主節(jié)點(diǎn)，提供所有服務(wù)。當(dāng)兩個RTU建立了通訊連接后，它們會就誰是主節(jié)點(diǎn)進(jìn)行協(xié)商，主節(jié)點(diǎn)條件包括，是否連接有更多的外圍設(shè)備，是否正在對外圍系統(tǒng)提供服務(wù)等等。當(dāng)確定誰是主節(jié)點(diǎn)后，兩個RTU就會自覺把自己設(shè)定為相應(yīng)的工作狀態(tài)。自動方式中的主備節(jié)點(diǎn)，要求它們在系統(tǒng)中具有不同的邏輯地址，以讓它們的客戶端能夠分別找到它們，并且確定它們的工作狀態(tài)，并對它們提供的信息進(jìn)行不同的處理。
在集控方式的實(shí)現(xiàn)中，主備節(jié)點(diǎn)在運(yùn)行時都向冗余控制器注冊，由冗余控制器確定他們的運(yùn)行方式，另外冗余控制器還擔(dān)任監(jiān)視主備節(jié)點(diǎn)運(yùn)行狀態(tài)的責(zé)任。當(dāng)主節(jié)點(diǎn)在設(shè)定的時間內(nèi)沒有響應(yīng)時，冗余控制器則重新設(shè)定主備節(jié)點(diǎn)的運(yùn)行方式，備節(jié)點(diǎn)代替主節(jié)點(diǎn)處理內(nèi)部信息、響應(yīng)請求。在這種情況下，主備節(jié)點(diǎn)具有使用相同的邏輯地址，它們的運(yùn)行狀態(tài)對客戶程序是透明的，所有的客戶請求都通過冗余控制器轉(zhuǎn)發(fā)給主節(jié)點(diǎn)。
在基于構(gòu)件的軟件架構(gòu)中，比如J2EE, CORBA, .NET, WEBSERVISE等，任一軟件構(gòu)件都具有唯一的構(gòu)件標(biāo)識，使構(gòu)件的客戶端可以準(zhǔn)確地定位構(gòu)件的位置，并請求服務(wù)。這就跟構(gòu)件冗余系統(tǒng)產(chǎn)生沖突，冗余系統(tǒng)要求所有構(gòu)件都要有主備節(jié)點(diǎn)，并且要求其主備模式對構(gòu)件的客戶端是透明的。這樣，支持主備構(gòu)件的尋址服務(wù)就成為系統(tǒng)不可缺少的基礎(chǔ)服務(wù)，它可以解析客戶的尋址請求，并把服務(wù)請求轉(zhuǎn)發(fā)給主節(jié)點(diǎn)構(gòu)件。
支持冗余的構(gòu)件本身，為了滿足苛刻的系統(tǒng)切換性能要求，必須針對具體情況特別設(shè)計。但有一點(diǎn)是共同的，就是主備構(gòu)件的數(shù)據(jù)同步。在任何情況下，當(dāng)主節(jié)點(diǎn)故障，備節(jié)點(diǎn)接管后，要能夠保持與主節(jié)點(diǎn)故障前同樣的內(nèi)部狀態(tài)信息。一種情況是主備節(jié)點(diǎn)中，同時只有一個節(jié)點(diǎn)從外部獲得信息并對外提供服務(wù)，這樣主備節(jié)點(diǎn)之間的數(shù)據(jù)同步，就需要同步所有的動態(tài)數(shù)據(jù)，而且只能通過主備節(jié)點(diǎn)間的通訊實(shí)現(xiàn)。由于主備節(jié)點(diǎn)通常不在相同的物理位置上，其間的通訊只能通過網(wǎng)絡(luò)實(shí)現(xiàn)，這樣就必須保證主備節(jié)點(diǎn)間數(shù)據(jù)同步的高效，不能占用大量的網(wǎng)絡(luò)帶寬。另一種情況是主備節(jié)點(diǎn)可以同時從外部獲得信息，但同時只有一個節(jié)點(diǎn)對外提供服務(wù)，這樣主備節(jié)點(diǎn)間的數(shù)據(jù)同步就會減少，只需要同步少量運(yùn)行狀態(tài)信息，但同樣會有缺點(diǎn)，它要求信息提供者可以支持同時給主備節(jié)點(diǎn)提供相同的信息。
