摘要
该文研究网络虚拟化环境下的跨域虚拟网络映射问题,提出一种集中式管理、分布式控制的分层分域虚拟网络资源管理架构。在此基础上,构建了一种有效的虚拟网络跨域映射框架,在此框架下将涉及到跨域的虚拟网络请求进行划分,并以最小化虚拟网络映射开销为目标,基于优化的人工蜂群算法进行最优划分方案的求解。仿真结果表明该方法在平均划分时间、虚拟网络请求接受率和平均额外映射等方面相比传统方法具有更好的性能。
Virtual network embedding is researched across multiple domains under network virtualization environment. A hierarchical virtual resource provisioning architecture with centralized management and distributed control is proposed. On this basis, an effective virtual network embedding across multiple domains framework is built, and virtual network request is divided, which aims to minimize the embedding cost. An Optimal Artificial Bee Colony（OABC） algorithm is proposed to address this problem. Simulation results show that the performances of the proposed method are better than some other methods on average divide time, acceptance of virtual network request, and average extra embedding cost.
