  • 摘要:

    針對虛擬環(huán)境下底層網(wǎng)絡(luò)中光纖的概率性故障，傳統(tǒng)的100%保護(hù)至少需要配置一條保護(hù)路徑，造成資源冗余度高和虛擬網(wǎng)絡(luò)請求接受率低的問題，該文提出一種基于安全性感知的差異化虛擬光網(wǎng)絡(luò)的映射(SA-DVNM)策略，在鏈路發(fā)生故障時為差異化虛擬網(wǎng)絡(luò)請求提供安全保證。在SA-DVNM策略中，設(shè)計了一個綜合考慮物理節(jié)點(diǎn)對之間跳數(shù)和相鄰帶寬大小的節(jié)點(diǎn)權(quán)重式避免鏈路映射過長，并提出路徑頻譜資源使用均衡的鏈路映射機(jī)制，最小化瓶頸鏈路的數(shù)量。當(dāng)單路徑傳輸失敗時，SA-DVNM策略設(shè)計允許路徑分割的資源分配機(jī)制，為保障時延敏感業(yè)務(wù)的安全性，SA-DVNM策略在路由選擇中設(shè)計了基于時延差優(yōu)化的多路徑路由頻譜分配方法。仿真結(jié)果表明該文所提策略在概率故障環(huán)境中能夠降低帶寬阻塞率，提高頻譜資源利用率和虛擬光網(wǎng)絡(luò)接受率。

    Abstract:

    Due to the probabilistic failure of the optical fiber of the underlying network in the virtual environment, traditional full protection configures one protection path at least which leads to high resource redundancy and low acceptance rate of the virtual network. In this paper, a Security Awareness-based Diverse Virtual Network Mapping (SA-DVNM) strategy is proposed to provide security guarantee in the event of failures. In SA-DVNM, the physical node weight formula is designed by considering the hops between nodes and the bandwidth of adjacent links, besides, a path-balanced link mapping mechanism is proposed to minimize the overloaded link. For improving the acceptability of virtual network, SA-DVNM strategy designs a resource allocation mechanism that allows path cut when a single path is unavailable for low security. Considering the difference of time delay to ensure the security of delay-sensitive services, a multipath routing spectrum allocation method based on delay difference is designed to optimize the routing and spectrum allocation for SA-DVNM strategy. The simulation results show that the proposed SA-DVNM strategy can improve the spectrum utilization and virtual optical network acceptance rate in the probabilistic fault environment, and reduce the bandwidth blocking probability.
