Research on Virtual Network Embedding Across Multiple Domains
Jia Wei, Jingbo Xia · 2016
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.
