【摘要】:隨著互聯(lián)網(wǎng)的廣泛普及,傳統(tǒng)的Client/Server網(wǎng)絡(luò)傳輸模式中服務(wù)器的性能瓶頸越來越難以滿足新分布式應(yīng)用的需求。Peer-to-Peer(P2P)網(wǎng)絡(luò)傳輸模式在大規(guī)模并行計(jì)算,分布式信息共享,協(xié)同工作等方面顯示出獨(dú)特優(yōu)勢。但是傳統(tǒng)基于業(yè)務(wù)的P2P信道建立模式對信息傳輸與業(yè)務(wù)邏輯同時進(jìn)行管理,浪費(fèi)了資源并且管理難度較大。 INSTLINK2即時通信系統(tǒng)中間件采用了以P2P模型為基礎(chǔ)的流媒體邏輯信道來進(jìn)行視頻,語音等即時或大數(shù)據(jù)流量業(yè)務(wù)信息的傳輸。本文旨在實(shí)現(xiàn)INSTLINK2中間件中采用的基于P2P技術(shù)建立的可復(fù)用流媒體邏輯信道架構(gòu),將信道對媒體流的傳輸與具體業(yè)務(wù)邏輯完全透明化。本文首先介紹了利用P2P模型進(jìn)行流媒體傳輸?shù)难芯勘尘耙约鞍l(fā)展現(xiàn)狀,強(qiáng)調(diào)了P2P信道在INSTLINK2中間件中的不可或缺性與中間件對信道可復(fù)用管理設(shè)計(jì)的創(chuàng)新性。接著研究了信道建立所應(yīng)用到的協(xié)議與標(biāo)準(zhǔn),主要是NAT規(guī)范,SIP協(xié)議與ICE標(biāo)準(zhǔn)。最后研究了INSTLINK2中間件底層設(shè)計(jì),并基于該設(shè)計(jì)與所使用協(xié)議實(shí)現(xiàn)了channel模塊的實(shí)現(xiàn)邏輯。 本文所研究完成的P2P邏輯流傳輸信道已經(jīng)經(jīng)過模塊測試并開始進(jìn)行INSTLINK2通信系統(tǒng)的系統(tǒng)測試。
[Abstract]:With the popularization of Internet, the bottleneck of server performance in traditional Client/Server network transmission mode is more and more difficult to meet the demand of new distributed application. Peer-to-PeerP2P) network transmission mode is widely used in parallel computing and distributed information sharing. But the traditional P2P channel building mode based on services manages the information transmission and business logic at the same time, which wastes resources and is difficult to manage. The middleware of INSTLINK2 instant communication system adopts streaming media logic channel based on P2P model to carry out video. The purpose of this paper is to implement a reusable streaming media logical channel architecture based on P2P technology in INSTLINK2 middleware. This paper firstly introduces the research background and development status of streaming media transmission using P2P model. The essentiality of P2P channel in INSTLINK2 middleware and the innovation of middleware in channel reusable management design are emphasized. Then the protocols and standards used in channel establishment are studied. Finally, the bottom layer design of INSTLINK2 middleware is studied, and the realization logic of channel module is realized based on the design and the protocol used. The P2P logical stream transmission channel studied in this paper has been tested by module and the system of INSTLINK2 communication system has been tested.
