To improve the resource utilization rate of cloud network data centers and save communication costs,a cloud network security service chain automatic orchestration method is designed based on SRv6(Segment Route IPv6)technology.The method assists and guides network data packets to pass through the cloud network along the specified path,determines the specific for-warding path of the message,and reduces dependence on service nodes;establishes an objective function to minimize the total bandwidth,combines with various constraints to meet the security requirements of automatic orchestration;defines local behav-ior message,constructs automatic arrangement framework of security service chain,establishes security service policy,solves policy conflict and flow network scheduling problem,and achieves security arrangement of service chain.Experimental results show that the proposed method can effectively implement the automatic scheduling of cloud service chain,reduce the average to-tal bandwidth consumption of CPU,improve the success rate of user requests,reduce the load of edge device in the cloud,and save communication costs.
