SDI (Software Defined Infrastructure) 環境において通信需要とサービス需要の変動に対し仮想ネットワークに物理的な資源割り当てを行うVNE (仮想網埋め込み) 問題がある。本稿では、大規模複雑かつ不確実なSDI環境のために少ない情報量で動作するVNE手法として、制御目標の汎用性を備え、かつ、多重スライス構成に対応可能なVNE手法として、ゆらぎ原理にもとづくVNE手法を提案する。計算機シミュレーションによる評価により、提案手法における仮想網の移行回数が、既存の発見的手法と比較して、約45%削減されることを示す。 |

SDI (Software Defined Infrastructure) provides virtualized infrastructures to customers by slicing computing resources and network resources. One of the important problems for deploying SDI framework is to control the assignment of physical resources to a virtual network against changes of traffic demand and service demand. For this problem, VNE (Virtual Network Embedding) problem that maps a virtual network to physical resources has been addressed, but a centralized calculation was assumed. It is difficult to adopt the centralized approaches as a size of infrastructure increases and a number of VN requests increases. This is because the identification of current situation becomes more complicated. In this paper, we present a VNE method that works with a little information for the large, complicated, and uncertain SDI frameworks.
To achieve this, the proposed method applies biological ``Yuragi'' principle.
Yuragi, which is a Japanese word, represents a small perturbation to the system. Yuragi is a mechanism of adaptability of organisms and is often expressed as attractor selection model. This paper develops Yuragi-based VNE method that deals with node attribute and has a generality of a performance objective and runs in multi-slice environments. Simulation results show that the Yuragi-based method decreases VN migrations by about 45% than a heuristic method to adapt the fluctuations in resource requirements. |
