1. A system for providing continuous service in a wireless communication network, wherein the system comprises:
a communication management controller comprising a plurality of ports;
a first distributed unit (DU) of a plurality of DUs connected to the communication management controller for communicating with a centralized unit (CU), wherein traffic associated with the first DU is provided as input to an active port of the communication management controller and the first DU is configured to set an alarm signal to a control port of the communication management controller indicating an active status of the first DU;
at least one second DU of the plurality of DUs connected to the first DU; and
wherein the communication management controller is configured to:
determine the alarm signal to the control port of the communication management controller is not set,
determine a failure of the first DU based on the alarm signal to the control port of the communication management controller is not set,
automatically switch the input from the active port to a default port of the communication management controller, wherein the default port is connected to the at least one second DU, and
provide continuous service in the wireless communication network by redirecting traffic associated with the first DU towards the at least one second DU.
