1. A radio access network (RAN) system comprises:
capsules that operate in parallel to cooperatively perform RAN stack operations, each capsule utilizing a processor and a memory configured to perform a corresponding component of the RAN stack operations, wherein a first subset of plurality of capsules is implemented by a first module under control of a first liquidity controller, wherein a second subset of capsules is implemented by a second module under control of a second liquidity controller, wherein the first subset of capsules are mutually exclusive of the second subset of capsules, wherein the first liquidity controller and the second liquidity controller cooperate to support a migration of a first capsule from the first subset of capsules to the second subset of capsules, and wherein the RAN stack operations result in:
communicating backhaul communications with a core communication network;
communicating fronthaul communications with a plurality of radio units configured to engage in wireless communications with a plurality of user equipment (UEs) via a radio channel of a radio network;
converting, in accordance with a communication standard, received fronthaul communications from the plurality of radio units into backhaul communications transmitted to the core communication network; and
converting, in accordance with the communication standard, received backhaul communications from the core communication network into fronthaul communications transmitted to the plurality of radio units.
