【摘要】：目前,軟件定義網(wǎng)絡(luò)(Software Defined Network),簡稱SDN,已經(jīng)在工業(yè)界和學(xué)術(shù)界引起了較大地反響與關(guān)注。它第一次創(chuàng)新性地實現(xiàn)了控制平面與數(shù)據(jù)平面的分離。然而,目前許多的SDN解決方案(例如：OpenFlow)僅僅可以讓用戶針對具體的,數(shù)據(jù)平面可支持的協(xié)議來配置這個協(xié)議內(nèi)的對數(shù)據(jù)流的操作方式。控制平面無法往數(shù)據(jù)平面下發(fā)一個全新的協(xié)議來讓數(shù)據(jù)平面可以識別這個協(xié)議,甚至去處理具備這個協(xié)議的數(shù)據(jù)流。而在現(xiàn)今的全球網(wǎng)絡(luò)中,傳統(tǒng)的IP交換已經(jīng)無法滿足日益復(fù)雜的網(wǎng)絡(luò)架構(gòu)以及多種多樣的網(wǎng)絡(luò)使用者對于網(wǎng)絡(luò)的不同需求。新的協(xié)議及其數(shù)據(jù)流處理模式不斷地被提出以使得網(wǎng)絡(luò)的性能與效率得到不斷地提升。在這種情形下,使用目前的SDN解決方案(例如：OpenFlow)無法使SDN網(wǎng)絡(luò)靈活地支持新的網(wǎng)絡(luò)協(xié)議,從而給第三方網(wǎng)絡(luò)開發(fā)者帶來了相當(dāng)大的困難。 本文以實現(xiàn)可由第三方網(wǎng)絡(luò)開發(fā)者通過軟件定義的手段配置自定義的協(xié)議到數(shù)據(jù)平面為目的,結(jié)合SDN的網(wǎng)絡(luò)控制平面與數(shù)據(jù)平面相分離的網(wǎng)絡(luò)架構(gòu),對SDN架構(gòu)進(jìn)行了擴(kuò)展,設(shè)計并實現(xiàn)了“支持多協(xié)議的SDN交換機(jī)”。支持多協(xié)議的SDN交換機(jī)采用了與協(xié)議無關(guān)的數(shù)據(jù)平面處理策略,使得協(xié)議的支持與數(shù)據(jù)平面的處理分隔開(松耦合),由第三方網(wǎng)絡(luò)開發(fā)者通過控制平面來配置自己需要的協(xié)議到某個(或某些)數(shù)據(jù)平面中使數(shù)據(jù)平面支持具有其協(xié)議的數(shù)據(jù)流的處理。 本文首先介紹了SDN網(wǎng)絡(luò)的基本架構(gòu),再詳細(xì)介紹了其較成熟的解決方案：OpenFlow的理念與架構(gòu)。然后,論文對現(xiàn)有的支持多協(xié)議的一些設(shè)計方案的優(yōu)缺點進(jìn)行了分析,并由此引出對“支持多協(xié)議的SDN交換機(jī)”的全面分析與設(shè)計,其中包括需求分析、總體設(shè)計和詳細(xì)設(shè)計。最后,本文對系統(tǒng)功能的實現(xiàn)進(jìn)行了單元測試和系統(tǒng)測試,同時提出了該系統(tǒng)需進(jìn)一步完善及改進(jìn)之處。
[Abstract]:At present, Software Defined Network, or SDN, has attracted much attention in industry and academia. It is the first time to realize the separation of control plane and data plane. Many of the current SDN solutions (such as: open flow) only allow users to be specific, The control plane cannot issue a new protocol below the data plane to enable the data plane to recognize the protocol. Even to process data streams with this protocol. And in today's global networks, The traditional IP switch has been unable to meet the increasing complexity of the network architecture and a variety of network users for the different needs of the network. New protocols and their data flow processing mode has been proposed to make the network performance. And increased efficiency. In this case, Using current SDN solutions, such as: open flow, does not enable SDN networks to flexibly support new network protocols, which creates considerable difficulties for third-party web developers. In this paper, the SDN architecture is extended to realize the configuration of self-defined protocols to the data plane by means of software definition by third-party network developers, combined with the network architecture in which the network control plane of SDN is separated from the data plane. This paper designs and implements the "SDN switch supporting multi-protocol". The multi-protocol SDN switch adopts a protocol independent data plane processing strategy. Enables protocol support to be separated from data plane processing (loosely coupled), where third-party network developers configure their desired protocols to a data plane (or data plane) by using the control plane so that the data plane support has a. Its protocol data stream processing. This paper first introduces the basic architecture of SDN network, then introduces the concept and architecture of its mature solution:: OpenFlow in detail. Then, the paper analyzes the advantages and disadvantages of some existing design schemes that support multi-protocol. From this, the overall analysis and design of "SDN switch supporting multi-protocol" are introduced, including requirement analysis, overall design and detailed design. Finally, the realization of system function is tested by unit test and system test. At the same time, the system needs to be further improved and improved.
