【摘要】：近年來,隨著VoIP技術(shù)的日益成熟,數(shù)據(jù)網(wǎng)絡(luò)語音通信越來越深的影響著人們生活,網(wǎng)絡(luò)電話用戶也與日俱增。隨著用戶量的快速增長,傳統(tǒng)的VoIP系統(tǒng)局限性日益凸顯,而P2P網(wǎng)絡(luò)的靈活性、自主性等特點很好彌補了上述局限,將SIP與P2P進(jìn)行結(jié)合成為新一代網(wǎng)絡(luò)電話的發(fā)展趨勢。論文首先對VoIP系統(tǒng)的基本原理及其相關(guān)技術(shù)進(jìn)行研究,其中包括對SI P協(xié)議和P2P網(wǎng)絡(luò)的分析,同時對Kademlia算法在網(wǎng)絡(luò)電話中面臨的不足進(jìn)行比較分析,為該算法的改進(jìn)提供了依據(jù)。在這些相關(guān)研究的基礎(chǔ)上,論文提出了P2PSI P融合的事實通信模型,模型重點對Ka deml ia算法進(jìn)行了優(yōu)化、對通信節(jié)點行為進(jìn)行定義、設(shè)定了通話信道建立與維護的策略、解決了NAT/FW穿越問題,為原型系統(tǒng)的具體實現(xiàn)提供了基礎(chǔ)知識。根據(jù)以上研究及設(shè)計思路,論文對P2P-SIP網(wǎng)絡(luò)電話原型系統(tǒng)進(jìn)行了設(shè)計實現(xiàn),并搭建模擬網(wǎng)絡(luò)環(huán)境進(jìn)行測試,測試結(jié)果表明該系統(tǒng)基本達(dá)到了相應(yīng)的技術(shù)指標(biāo),通過縱向?qū)Ρ仍囼?證明了改進(jìn)的Kademlia算法在性能上得到了較大提升。綜上,本論文實現(xiàn)了預(yù)定的設(shè)計目標(biāo),證明了論文所采用方法的有效性。
[Abstract]:In recent years, with the maturation of VoIP technology, the voice communication of data network has more and more influence on people's lives, and the number of network telephone users is also increasing. With the rapid growth of the number of users, the limitations of traditional VoIP systems become increasingly prominent, and the flexibility and autonomy of P2P networks make up for these limitations. Combining SIP with P2P has become the development trend of the new generation of network telephony. In this paper, the basic principles and related technologies of VoIP system are studied, including the analysis of SI P protocol and P2P network, and the comparison and analysis of the shortage of Kademlia algorithm in network phone. It provides the basis for the improvement of the algorithm. On the basis of these related studies, the paper puts forward a P2PSI P fusion model of factual communication. The model focuses on optimizing the Ka deml ia algorithm, defining the behavior of communication nodes, and setting up the strategy of establishing and maintaining the communication channel. The problem of NAT/FW traversal is solved and the basic knowledge is provided for the implementation of the prototype system. According to the above research and design ideas, this paper designs and implements the P2P-SIP network telephone prototype system, and builds an analog network environment for testing. The test results show that the system basically reaches the corresponding technical targets. Through longitudinal contrast experiment, it is proved that the improved Kademlia algorithm has better performance. In summary, this paper achieves the predetermined design goal, and proves the effectiveness of the method used in the paper.
