【摘要】：隨著移動(dòng)互聯(lián)網(wǎng)的迅速發(fā)展,使用手機(jī)等移動(dòng)終端進(jìn)行移動(dòng)上網(wǎng)的網(wǎng)民越來(lái)越多。與此同時(shí),移動(dòng)網(wǎng)絡(luò)帶寬資源變得日益緊張,而且對(duì)網(wǎng)絡(luò)的優(yōu)化也變得更加困難和復(fù)雜。如何在現(xiàn)有網(wǎng)絡(luò)帶寬的基礎(chǔ)上有效地對(duì)移動(dòng)網(wǎng)絡(luò)進(jìn)行優(yōu)化是移動(dòng)互聯(lián)網(wǎng)發(fā)展的關(guān)鍵問(wèn)題,具有很重要的現(xiàn)實(shí)意義。 目前針對(duì)移動(dòng)網(wǎng)絡(luò)的優(yōu)化和加速問(wèn)題,理論研究的重點(diǎn)主要側(cè)重于對(duì)各種移動(dòng)網(wǎng)絡(luò)加速技術(shù)以及新型的網(wǎng)絡(luò)架構(gòu)的研究,但是移動(dòng)平臺(tái)上相關(guān)的應(yīng)用產(chǎn)品還處于起步階段。本文通過(guò)創(chuàng)新性地融合多種網(wǎng)絡(luò)加速技術(shù)以及合理的網(wǎng)絡(luò)架構(gòu)設(shè)計(jì)進(jìn)而實(shí)現(xiàn)一個(gè)移動(dòng)網(wǎng)絡(luò)加速系統(tǒng)。 首先,在研究和分析了現(xiàn)有的內(nèi)容網(wǎng)絡(luò)架構(gòu)和面向未來(lái)的網(wǎng)絡(luò)架構(gòu)的基礎(chǔ)上,提煉出了一個(gè)具備內(nèi)容感知能力的移動(dòng)網(wǎng)絡(luò)部署架構(gòu)。這個(gè)架構(gòu)通過(guò)在現(xiàn)網(wǎng)基礎(chǔ)上增加用戶層、邊緣代理服務(wù)層和控制中心服務(wù)層,并采用了基于最近訪問(wèn)和有限多徑探測(cè)的資源定位算法,在應(yīng)用層打造一個(gè)基于內(nèi)容的感知層來(lái)對(duì)用戶的網(wǎng)絡(luò)請(qǐng)求進(jìn)行全方位的感知。 其次,在上述內(nèi)容感知網(wǎng)絡(luò)架構(gòu)的基礎(chǔ)上,針對(duì)不同的網(wǎng)絡(luò)請(qǐng)求融合了多種網(wǎng)絡(luò)加速方法。并且針對(duì)這些不同特點(diǎn)和適用情況的加速技術(shù),在用戶層移動(dòng)端本地代理和邊緣代理服務(wù)層上分別設(shè)計(jì)了配套的智能決策流程。這樣達(dá)到對(duì)每一個(gè)網(wǎng)絡(luò)請(qǐng)求靈活地使用相應(yīng)的優(yōu)化方案,提升系統(tǒng)的智能性。 最后,.基于內(nèi)容感知和智能決策的功能,主要在Android移動(dòng)平臺(tái)上設(shè)計(jì)和實(shí)現(xiàn)了高性能且穩(wěn)定的移動(dòng)端本地代理應(yīng)用,和后臺(tái)部署的服務(wù)器一起完成了整體的加速功能。這個(gè)Android應(yīng)用具有靈活配置功能以及良好的用戶交互接口,帶來(lái)了良好的用戶體驗(yàn)。
[Abstract]:With the rapid development of mobile Internet, more and more Internet users use mobile terminals such as mobile phones to access the Internet. At the same time, the bandwidth resources of mobile network become increasingly tight. How to optimize the mobile network effectively on the basis of the existing network bandwidth is a key issue in the development of the mobile Internet, which has a very important practical significance. At present, for the optimization and acceleration of mobile networks, the focus of theoretical research is mainly on the various mobile network acceleration technologies and new network architecture. However, the related application products on mobile platform are still in their infancy. In this paper, a mobile network acceleration system is implemented through the innovative integration of various network acceleration technologies and reasonable network architecture design. First of all, based on the research and analysis of the existing content network architecture and future-oriented network architecture. A content-aware mobile network deployment architecture is developed, which adds user layer, edge agent service layer and control center service layer to the current network. The resource location algorithm based on recent access and finite multipath detection is used to create a content-based awareness layer in the application layer to fully perceive the users' network requests. Secondly, on the basis of the above content aware network architecture, a variety of network acceleration methods are integrated for different network requests, and according to these different characteristics and applicable acceleration technology. The corresponding intelligent decision flow is designed on the mobile local agent and edge agent service layer of the user layer, which can flexibly use the corresponding optimization scheme for each network request and enhance the intelligence of the system. Finally, based on the function of content awareness and intelligent decision, the high performance and stable local agent application of mobile side is designed and implemented on Android mobile platform. The Android application has a flexible configuration function and a good user interaction interface, which brings a good user experience.
