Service function chain mapping method and system, electronic equipment and storage medium

The invention relates to the field of virtual networks, and discloses a service function chain mapping method and system, an electronic device and a storage medium, a fitness value is calculated through a sparrow algorithm, and the lower the total network cost for deploying a current service function chain is, the higher the fitness value is, so that a low-network-cost optimal mapping scheme for deploying the service function chain is obtained. Therefore, the mapping of the service function chain is more flexible and efficient, and the deployment with resource balance and optimal cost can be realized in a complex network environment. In addition, the method has universality for different network topology structures and service function chain requests, and is suitable for various virtualized network scenes. 本发明涉及虚拟网络领域，公开了一种服务功能链映射方法、系统、电子设备和存储介质，通过麻雀算法计算适应度值，且部署当前服务功能链的总网络成本越低，适应度值越高，从而得到部署服务功能链的低网络成本的最优映射方案，使得服务功能链映射更加灵活、高效，并能在复杂网络环境下实现资源均衡和成本最优的部署。此外，该方法对于不同网络拓扑结构和服务功能链请求具有通用性，适用于各种虚拟化网络场景。
