| Resumen: | Network function virtualization achieves the softwareization of network functions through virtualization technology, reducing operational costs but introducing challenges in network orchestration complexity. To deploy service function chains efficiently and cost-effectively in a network function virtualization environment, a latency-guaranteed, optimized mapping method is proposed. Firstly, a model that minimizes the total network deployment cost for service function chains is established, comprehensively considering user latency requirements and network resource constraints. Secondly, a service function chain mapping method based on an improved sparrow search algorithm is introduced. Finally, the simulation results show that the bandwidth resource utilization of the ISSA-SFCM algorithm is improved by 3.8% and 8.5%, respectively, compared to the control DP-COA algorithm and First-Fit algorithm, with a higher service function chain request acceptance rate and lower average network cost. |
