1.一種在IPV4網(wǎng)絡(luò)中透傳IPV6數(shù)據(jù)包的方法,其特征在于,包括以下步驟:
步驟S101,IPV6數(shù)據(jù)包發(fā)送終端向IPV6數(shù)據(jù)包接收終端發(fā)送IPV6數(shù)據(jù)包,該數(shù)據(jù)包為標(biāo)準(zhǔn)IPV6格式;
步驟S102,數(shù)據(jù)包到達(dá)發(fā)送方轉(zhuǎn)換路由,發(fā)送方轉(zhuǎn)換路由判斷下一跳路由是否IPV6網(wǎng)絡(luò),如果下一跳是IPV6網(wǎng)絡(luò),進(jìn)入步驟S103,否則進(jìn)入步驟S104;
步驟S103,發(fā)送方轉(zhuǎn)換路由直接轉(zhuǎn)發(fā)IPV6數(shù)據(jù)到下一跳路由;
步驟S104,發(fā)送方轉(zhuǎn)換路由將IPV6數(shù)據(jù)包拆分,并添加IPV4數(shù)據(jù)包頭,組裝為IPV4數(shù)據(jù)包,此處的IPV4數(shù)據(jù)包為符合互聯(lián)網(wǎng)協(xié)議的標(biāo)準(zhǔn)IPV4數(shù)據(jù)包,進(jìn)入步驟S105;
步驟S105,發(fā)送方轉(zhuǎn)換路將組裝后的IPV4數(shù)據(jù)包轉(zhuǎn)發(fā)進(jìn)IPV4網(wǎng)絡(luò),進(jìn)入步驟S106;
步驟S106,IPV4網(wǎng)絡(luò)將組裝的IPV4數(shù)據(jù)包轉(zhuǎn)發(fā)至接收方轉(zhuǎn)換路由,進(jìn)入步驟S107;
步驟S107,接收方轉(zhuǎn)換路由判斷下一跳是否為IPV6網(wǎng)絡(luò),如果下一跳不是IPV6網(wǎng)絡(luò),進(jìn)入步驟S108,否則進(jìn)入步驟S109;
步驟S108,發(fā)送方轉(zhuǎn)換路由直接轉(zhuǎn)發(fā)IPV6數(shù)據(jù)到下一跳路由;
步驟S109,接收方轉(zhuǎn)換路由將IPV4數(shù)據(jù)包中的數(shù)據(jù)提取出來,重組為IPV6數(shù)據(jù)包,此處IPV6數(shù)據(jù)包為符合IPV6協(xié)議的標(biāo)準(zhǔn)IPV6數(shù)據(jù)包,進(jìn)入步驟S110;
步驟S110,接收方轉(zhuǎn)換路由將重組的IPV6數(shù)據(jù)包發(fā)送給IPV6數(shù)據(jù)包接收終端,進(jìn)入步驟S111;
步驟S111,IPV6數(shù)據(jù)包接收終端收到IPV6數(shù)據(jù)包。
