3）ICMP協(xié)議。
ICMP是Internet控制報(bào)文協(xié)議，是IP的一個(gè)附件，用于幫助網(wǎng)絡(luò)上所有節(jié)點(diǎn)實(shí)現(xiàn)簡(jiǎn)單的診斷并返回錯(cuò)誤消 息。它傳遞差錯(cuò)報(bào)文以及其他需要注意的信息。ICMP報(bào)文通常被P層或更高層協(xié)議（TCP或UDP）使用。
Ping程序是對(duì)兩個(gè)TCP/IP系統(tǒng)連通性進(jìn)行測(cè)試的工具。它只利用ICMP回顯請(qǐng)求和應(yīng)答報(bào)文。構(gòu)造回顯應(yīng)答 報(bào)文比較簡(jiǎn)單，代碼字段總是0，標(biāo)識(shí)符和序號(hào)字段設(shè)置成請(qǐng)求的發(fā)送方，回答中也不作修改。源系統(tǒng)可以 用這些字段匹配請(qǐng)求和回答。
在本模塊中，從RTL8019AS中，將ICMP首部數(shù)據(jù)發(fā)送，檢查其是否為echo要求（Ping要求）。如果是echo 要求的話，將echo應(yīng)答首部和接收的數(shù)據(jù)發(fā)送至源端。
（4）tCPi辦議。 ˇ
rap提供了一種可靠的、面向連接的字節(jié)流運(yùn)輸層服務(wù)。面向連接意味著兩個(gè)使用rap的應(yīng)用（通常是一個(gè) 客戶和一個(gè)服務(wù)器）在彼此交換數(shù)據(jù)之前必須先建立一個(gè)rap連接。
在一個(gè)TCP連接中，僅有兩方進(jìn)行彼此通信。TCP通過(guò)下列方式來(lái)提供可靠性。
· 應(yīng)用數(shù)據(jù)被分割成rap認(rèn)為發(fā)送的數(shù)據(jù)塊，由TOP傳遞給IP的信息單位稱為報(bào)文段（Segment）。
· 當(dāng)rap發(fā)出一個(gè)段后，它啟動(dòng)一個(gè)定時(shí)器，等待目的端確認(rèn)收到這個(gè)報(bào)文段。如果不能及時(shí)收到一個(gè)確 認(rèn)，將重發(fā)這個(gè)報(bào)文段。
· 當(dāng)rap收到發(fā)自TOP連接的另一端的數(shù)據(jù)，它將發(fā)送一個(gè)確認(rèn)。這個(gè)確認(rèn)不是立即發(fā)送，通常將推遲幾 分之一秒。
· rap將保持它首部和數(shù)據(jù)的檢驗(yàn)和。這是一個(gè)端到端的檢驗(yàn)和，目的是檢測(cè)數(shù)據(jù)在傳輸過(guò)程中的變化。 如果收到段的檢驗(yàn)和有差錯(cuò)，rap將丟棄這個(gè)報(bào)文段并不確認(rèn)收到此報(bào)文段。
· 既然rap報(bào)文段作為IP數(shù)據(jù)報(bào)傳送，而IP數(shù)據(jù)報(bào)的到達(dá)可能會(huì)失序，因此TCP報(bào)文段的到達(dá)也可能會(huì)失 序。如果必要，TCP將對(duì)收到的數(shù)據(jù)進(jìn)行重新排序，將收到的數(shù)據(jù)以正確的順序交給應(yīng)用層。
· IP數(shù)據(jù)報(bào)會(huì)發(fā)生重復(fù)，TOP的接收端必須丟棄重復(fù)的數(shù)據(jù)。
· rap還能提供流量控制。rap連接的每一方都有固定大小的緩沖空間。TOP的接收端只允許另一端發(fā)送接 收端緩沖區(qū)所能接納的數(shù)據(jù)，這將防止較快主機(jī)至使較慢主機(jī)的緩沖區(qū)溢出。
· TCP協(xié)議的接收應(yīng)答機(jī)制、亂序到達(dá)數(shù)據(jù)的順序化及接收受損報(bào)文的重傳機(jī)制確保了TCP協(xié)議的可靠性 。
本模塊在技術(shù)數(shù)據(jù)上，并不要求其自身建立TCP/IP連接，所以采用只存在Web服務(wù)器的TCP狀態(tài)遷移圖。
