1. A server system, comprising:
a first message controller associated with a first layer two (L2) of a first Radio Access Network (RAN) server; and
memory storing instructions that, when executed by a processor, cause the first message controller to perform operations, comprising:
intercepting, from the first L2 of the first RAN server, a first request directed to a first layer one (PHY) of the first RAN server, wherein the first request includes first information for performing signal processing of one or more first radio unit (RU) signals of a radio unit (RU);
duplicating the first request, wherein duplicating the first request comprises removing the first information to form a first null request;
routing the first request including the first information to the first PHY of the first RAN server, wherein the first PHY is active and performs the signal processing on the one or more first RU signals of the RU based on the first information; and
routing the first null request not including the first information to a second layer one (PHY) of the second RAN server, wherein the second PHY is alive based on receiving the first null request, and wherein the second PHY is inactive based on the first null request not including the first information.
