【摘要】：隨著互聯(lián)網(wǎng)的快速發(fā)展和網(wǎng)絡(luò)新業(yè)務(wù)的不斷出現(xiàn),對光傳輸網(wǎng)絡(luò)提出了更多的要求,在這種趨勢下,傳統(tǒng)的網(wǎng)絡(luò)分層架構(gòu)已無法滿足日益增長的需求,對于互聯(lián)網(wǎng)的發(fā)展已經(jīng)成為一個障礙,這類問題被稱為網(wǎng)絡(luò)僵化問題。在此背景下,網(wǎng)絡(luò)虛擬化已經(jīng)越來越多地被看作是互聯(lián)網(wǎng)僵化的一個解決方案。本文介紹了光網(wǎng)絡(luò)的特點,在分析現(xiàn)有技術(shù)的基礎(chǔ)上,提出了基于Web Service的虛擬化光網(wǎng)絡(luò)資源管理技術(shù)。通過對光網(wǎng)絡(luò)虛擬化概念及其研究意義的分析,給出了本文的主要理論背景。分析了本文的涉及的主要技術(shù)架構(gòu),包括Web Service和.NET相關(guān)技術(shù)。其次,研究了光網(wǎng)絡(luò)的虛擬化關(guān)鍵技術(shù)問題,包括光網(wǎng)絡(luò)節(jié)點虛擬化和光網(wǎng)絡(luò)鏈路虛擬化技術(shù),對光網(wǎng)絡(luò)資源進(jìn)行了屬性抽象,為虛擬化光網(wǎng)絡(luò)資源管理做了準(zhǔn)備。并闡述了資源映射的過程,同時對映射算法進(jìn)行了對比分析和研究。在Visual Studio集成開發(fā)環(huán)境下,使用C#編程語言結(jié)合.NET編程平臺重點設(shè)計了基于Web Service的虛擬化光網(wǎng)絡(luò)資源管理模擬系統(tǒng),模擬了普通用戶和管理員用戶對光資源模塊各種管理和操作行為。最后,展示了基于Web Service虛擬化光資源管理運行實例,通過普通用戶和管理員兩種角色對系統(tǒng)進(jìn)行了深度測試,驗證了光網(wǎng)絡(luò)資源管理系統(tǒng)的可行性和有效性。本課題設(shè)計的系統(tǒng)可以有效解決網(wǎng)絡(luò)僵化問題,提高網(wǎng)絡(luò)管理的靈活性和方便性。
[Abstract]:With the rapid development of the Internet and the continuous emergence of new network services, the optical transmission network has put forward more requirements. Under this trend, the traditional network layered architecture can no longer meet the increasing demand. The development of the Internet has become an obstacle, such problems are called network ossification. Network virtualization has been more and more regarded as a solution to Internet fossilization. This paper introduces the characteristics of optical network, based on the analysis of existing technologies, This paper puts forward the resource management technology of virtualized optical network based on Web Service. Through the analysis of the concept of virtualization of optical network and its research significance, the main theoretical background of this paper is given, and the main technical framework involved in this paper is analyzed. Secondly, the key technologies of optical network virtualization, including optical network node virtualization and optical network link virtualization, are studied. This paper makes preparation for resource management of virtualized optical network, and expounds the process of resource mapping. At the same time, it makes a comparative analysis and research on mapping algorithm. Under the environment of Visual Studio integrated development, Using C # programming language and .NET programming platform, the virtual optical network resource management simulation system based on Web Service is designed, which simulates all kinds of management and operation behaviors of optical resource module by ordinary users and administrator users. An example of virtualization of optical resource management based on Web Service is presented, and the system is tested in depth through two roles: ordinary user and administrator. The feasibility and effectiveness of the optical network resource management system are verified. The system designed in this paper can effectively solve the problem of network rigidity and improve the flexibility and convenience of network management.
