【摘要】：數(shù)據(jù)中心是現(xiàn)在網(wǎng)絡(luò)系統(tǒng)中的重要一環(huán),隨著網(wǎng)絡(luò)用戶需求的不斷變化,數(shù)據(jù)中心的規(guī)模和復(fù)雜度隨之增加,這使得傳統(tǒng)的數(shù)據(jù)中心光網(wǎng)絡(luò)資源的管理方法不能很好的適應(yīng)新的業(yè)務(wù)需求,希望有更為智能的方法來管理光網(wǎng)絡(luò),能根據(jù)業(yè)務(wù)需求和特點來實現(xiàn)個性化的光網(wǎng)絡(luò)資源分配策略。 對于數(shù)據(jù)中心光網(wǎng)絡(luò)管理的新需求,本文引入了軟件定義網(wǎng)絡(luò)技術(shù),并把數(shù)據(jù)中心的服務(wù)遷移場景作為案例進(jìn)行討論。軟件定義網(wǎng)絡(luò)把全網(wǎng)的控制功能集中在控制器,各個節(jié)點僅需完成簡單的轉(zhuǎn)發(fā)功能。本文在數(shù)據(jù)中心的服務(wù)遷移中,把控制部分集總在控制器,設(shè)計了整體流程方案。 本文設(shè)計實現(xiàn)了采用軟件定義網(wǎng)絡(luò)的數(shù)據(jù)中心光網(wǎng)絡(luò)的網(wǎng)絡(luò)管理系統(tǒng)。與ASON的網(wǎng)管相比,兩者的異同如下： 1)兩者在網(wǎng)絡(luò)信息展示方面相似,都需要可視化顯示網(wǎng)絡(luò)拓?fù)洹⑹占y(tǒng)計網(wǎng)絡(luò)信息、實時反映網(wǎng)絡(luò)故障報警消息等； 2)兩者的不同在于網(wǎng)管與控制平面的通信協(xié)議及部分分工不同,在使用軟件定義網(wǎng)絡(luò)技術(shù)時,需要對協(xié)議進(jìn)行擴(kuò)展,以適應(yīng)光網(wǎng)絡(luò)。 因此,在設(shè)計實現(xiàn)使用軟件定義網(wǎng)絡(luò)的數(shù)據(jù)中心光網(wǎng)絡(luò)網(wǎng)管系統(tǒng)時,完成了如下3個部分： 1)實現(xiàn)常規(guī)的網(wǎng)管系統(tǒng)的信息顯示功能； 2)把部分控制功能交給控制器,并通過接口獲得計算結(jié)果,將結(jié)果展示給用戶�，F(xiàn)在軟件定義網(wǎng)絡(luò)使用最廣泛的協(xié)議是openflow協(xié)議,但openflow協(xié)議沒有明確定義控制器和光網(wǎng)管之間的北向接口。所以在實現(xiàn)光網(wǎng)絡(luò)管理系統(tǒng)時,本文根據(jù)openflow協(xié)議中控制器與交換機(jī)之間的南向接口,進(jìn)行了控制器與網(wǎng)管之間北向接口的擴(kuò)展,以完成網(wǎng)管與控制器的通信功能； 3)實現(xiàn)節(jié)點設(shè)備配置等人工配置功能,用于網(wǎng)絡(luò)管理者手動設(shè)置網(wǎng)絡(luò)節(jié)點。
[Abstract]:Data center is an important part of network system nowadays. With the continuous change of network user's demand, the scale and complexity of data center increase with it. This makes the traditional data center optical network resource management method can not adapt to the new business requirements, hope to have a more intelligent way to manage the optical network, The resource allocation strategy of individual optical network can be realized according to the service requirement and characteristics. For the new requirement of data center optical network management, this paper introduces software definition network technology, and discusses the service migration scenario of data center as a case study. The software defines the network to concentrate the whole network control function in the controller, each node only needs to complete the simple forwarding function. In the data center service migration, the control part is integrated in the controller, and the overall flow scheme is designed. This paper designs and implements the network management system of data center optical network which is defined by software. Compared with Ason network management, the similarities and differences between them are as follows: 1) both of them are similar in network information display, need to visualize network topology, collect network information, and reflect network fault alarm information in real time. 2) the difference between them lies in the difference of communication protocol and partial division of labor between network management and control plane. When using software to define network technology, it is necessary to extend the protocol to adapt to optical network. Therefore, in the design and implementation of the data center optical network management system using software to define the network, the following three parts are completed: 1) realizing the information display function of the conventional network management system; 2) give part of the control function to the controller, get the calculation result through the interface, and show the result to the user. The most widely used protocol for software-defined networks is the openflow protocol, but the openflow protocol does not clearly define the northward interface between the controller and the optical network management. So in the realization of optical network management system, according to the southern interface between controller and switch in openflow protocol, this paper extends the north interface between controller and network management, in order to complete the communication function between network management and controller. 3) realize manual configuration function such as node equipment configuration, which is used for network manager to set network node manually.
