Abstract
In order to fulfill the multicast task with a service function chain (SFC) requirement and effectively utilize network bandwidth and resources, a low-cost NFV multicast optimization strategy based on Dijkstra’s algorithm is proposed for the real-time requirements of wireless network data transmission scenarios. Taking network resource consumption and link bandwidth consumption as evaluation indicators, on the premise of meeting the Service Function Tree (SFT) delay requirements, the Virtual Network Function (VNF) is placed reasonably to realize the embedding of the Service Function Chain (SFC). It creatively proposes the merge rule of VNF in the SFC chain, which reduces the consumption of node resources and link bandwidth while ensuring the connectivity of the network. Experimental results show that the algorithm can effectively reduce the consumption of node resources and link bandwidth under the condition of ensuring low delay, and ensure the real-time and reliability of data transmission.
