Explanation

A business chain is a technology that provides orderly services to the application layer. By defining the service chain path, you can make the matching traffic pass through the specified VAS devices (such as firewall, load balancer, in-depth inspection, intrusion prevention, etc.) in turn, so as to obtain the corresponding value-added services in turn. The use of service chains helps to use the same network to provide differentiated value-added services for different services, and the orchestration of service chains through the controller can quickly set the traffic path when customer services are delivered to meet the network function requirements of customer services.
