【摘要】：傳統(tǒng)的互聯(lián)網(wǎng)構(gòu)架模型已難以滿足消費(fèi)者層出不窮的新興應(yīng)用要求,網(wǎng)絡(luò)虛擬化作為解決當(dāng)前互聯(lián)網(wǎng)僵化問題的技術(shù)手段,近年來受到了國內(nèi)外新一代網(wǎng)絡(luò)研究領(lǐng)域的廣泛關(guān)注。如何在異構(gòu)的物理環(huán)境下設(shè)計(jì)出既能滿足虛擬網(wǎng)用戶資源需求,又能最大化利用物理網(wǎng)絡(luò)資源的資源分配算法,是網(wǎng)絡(luò)虛擬化技術(shù)亟待解決的問題。本文根據(jù)博弈論的思想,將合作博弈與非合作博弈相結(jié)合,提出了基于混合博弈的競爭模型,并根據(jù)業(yè)務(wù)類型把虛擬網(wǎng)劃分為不同的服務(wù)類型,提出虛擬網(wǎng)絡(luò)資源動(dòng)態(tài)分配方法。仿真結(jié)果表明,本文提出的基于混合博弈的虛擬網(wǎng)絡(luò)動(dòng)態(tài)資源分配方案相對(duì)于傳統(tǒng)資源分配方案而言,充分利用了基礎(chǔ)設(shè)施提供商提供的物理資源,同時(shí)有效預(yù)防鏈路擁塞,增加了用戶滿意度。
[Abstract]:The traditional Internet architecture model has been difficult to meet the emerging application requirements of consumers. As a technical means to solve the problem of current Internet fossilization, network virtualization has been widely concerned in the field of new generation of network research both at home and abroad in recent years. How to design the virtual network users in the heterogeneous physical environment can satisfy the virtual network users. Resource allocation algorithm, which can maximize the utilization of physical network resources, is an urgent problem for network virtualization technology. Based on the idea of game theory, this paper combines the cooperative game with the non cooperative game, and puts forward a competition model based on the mixed game, and divides the virtual network into different service classes according to the business type. The simulation results show that the proposed hybrid game based virtual network dynamic resource allocation scheme, compared with the traditional resource allocation scheme, makes full use of the physical resources provided by infrastructure providers, at the same time it can effectively prevent link congestion and increase user satisfaction.
