【摘要】：隨著信息技術(shù)的不斷發(fā)展，嵌入式系統(tǒng)聯(lián)網(wǎng)應(yīng)用變得十分普及。目前，IP網(wǎng)絡(luò)及其應(yīng)用正處于IPv4向IPv6過渡時(shí)期，由于IPv6不是向下兼容的，因此IPv4網(wǎng)絡(luò)應(yīng)用不能直接過渡到IPv6環(huán)境中。另外，由于IPv6網(wǎng)絡(luò)和嵌入式系統(tǒng)的移動(dòng)性、分布性和大規(guī)模部署，導(dǎo)致網(wǎng)絡(luò)配置工作變得十分復(fù)雜。 本文研究了嵌入式系統(tǒng)自主IP聯(lián)網(wǎng)若干關(guān)鍵技術(shù)。為了解決IPv4應(yīng)用程序不能直接過渡到IPv6環(huán)境下的問題，本文以視頻傳送應(yīng)用為背景，設(shè)計(jì)和實(shí)現(xiàn)了一種基于IPv6的流媒體傳送方案。首先，分析IPv4與IPv6套接字編程接口差異；其次，以開源流媒體框架Live555為基礎(chǔ)，，分別從底層通信模塊和上層協(xié)議模塊進(jìn)行網(wǎng)絡(luò)協(xié)議的轉(zhuǎn)換；設(shè)計(jì)流媒體播放器用于對上述方案測試；最后，總結(jié)IPv4向IPv6網(wǎng)絡(luò)應(yīng)用過渡一般方法。為了解決IPv6環(huán)境嵌入式系統(tǒng)聯(lián)網(wǎng)復(fù)雜性問題，通過對比DHCP與DHCPv6之間的異同點(diǎn)，設(shè)計(jì)和實(shí)現(xiàn)一種用于嵌入式環(huán)境下的DHCPv6客戶端軟件，并在此基礎(chǔ)上實(shí)現(xiàn)DHCP和DHCPv6的自主適配。 本文對上述方案進(jìn)行功能性測試。測試結(jié)果表明，視頻傳送方案在IPv6環(huán)境下運(yùn)行正常，實(shí)現(xiàn)了IPv4向IPv6網(wǎng)絡(luò)應(yīng)用的順利過渡。DHCPv6客戶端能夠完成主機(jī)IPv6地址的自動(dòng)配置和租約更新等基本功能，與服務(wù)器報(bào)文交互過程符合協(xié)議規(guī)范，保持與DHCPv6協(xié)議的一致性，DHCPv6與DHCP自主適配過程符合系統(tǒng)需求。
[Abstract]:With the continuous development of information technology, embedded system networking applications become very popular. At present, IP network and its applications are in the transition period from IPv4 to IPv6, because IPv6 is not downward compatible. Therefore, IPv4 network applications can not be directly transferred to IPv6 environment. In addition, because of the mobility, distribution and large-scale deployment of IPv6 networks and embedded systems, network configuration becomes very complex. In order to solve the problem that IPv4 application can not directly transition to IPv6 environment, this paper takes video transmission application as the background, in order to solve the problem of embedded system autonomous IP networking, in order to solve the problem that IPv4 application can not be directly transferred to IPv6 environment. A streaming media transmission scheme based on IPv6 is designed and implemented. Firstly, the differences between IPv4 and IPv6 socket programming interface are analyzed. Secondly, the open source streaming media framework Live555 is used as the foundation. Respectively from the bottom communication module and the upper layer protocol module network protocol conversion; designed streaming media player to test the above scheme; finally, In order to solve the complexity of embedded system networking in IPv6 environment, a kind of DHCPv6 client software for embedded environment is designed and implemented by comparing the similarities and differences between DHCP and DHCPv6. On this basis, the DHCP and DHCPv6 self-adaptation is realized. The test results show that the video transmission scheme works well in IPv6 environment. It realizes the smooth transition from IPv4 to IPv6 network application. DHCPv6 client can automatically configure the host IPv6 address and renew the lease, and the process of exchanging messages with the server conforms to the protocol specification. Maintain consistency with DHCPv6 protocol. DHCPv6 and DHCP autonomic adaptation process meet system requirements.
