Scaling datapath pods of a RIC in a ran

Some embodiments of the invention provide a method for increasing system capacity of a RIC in a RAN, the RIC including a first datapath pod for forwarding communications between a first set of RAN applications connected to the RIC and a first set of base station components connected to the RIC. The method uses the first datapath pod to forward communications between the first set of RAN applications and the first set of base station components. The method determines that the first datapath pod has insufficient resources for forwarding traffic between the first set of base station components and the first set of RAN applications. Based on said determination, the method configures a second datapath pod on the RIC for forwarding traffic between the first set of base station components and the first set of RAN applications. The method assigns a first subset of the first set base station components to the first datapath pod and a second subset of the first set of base station components to the second datapath pod.
