| 摘 要： | 通过跨域映射能够为虚拟网提供更多的底层资源，但跨域映射策略也需要对网络运营商的自私性进行考虑。为此，提出一种面向收益最大化的虚拟网跨域映射策略，该策略通过引入域节点的概念来建立虚拟网拓扑分割和本地映射方案的同步求解模型，然后设计了一种基于遗传进化思想的本地映射算法对模型进行求解。仿真实验表明，该策略不但能提高运营商的收益，而且能够有效降低映射所需的开销。

| Abstract: | Inter-domain embedding is able to offer more substrate resources for virtual networks, and it is also necessary for inter-domain embedding policy to consider the selfishness of network providers. Therefore, an inter-domain virtual network embedding policy for revenue maximization is presented in this paper. This policy introduces the concept of domain node to build the synchronous solving model of virtual network topology division and local embedding, then designs a local embedding algorithm based on genetic evolution to solve this model. Evaluations show that this policy not only increases the revenue of network providers, but also reduces the embedding cost. |

| Keywords: | virtual network inter-domain embedding domain node revenue embedding cost |
