1. A system, comprising: a controller comprising: one or more first memory units configured to store one or more first instructions; and one or more first processors coupled to the first memory units and configured, upon executing the one or more first instructions, to: determine an instruction to be performed by a remote device; determine a token associated with the instruction; and transmit the token to the remote device; and a remote device comprising: one or more second memory units configured to store one or more second instructions, a plurality of preloaded instructions, and a plurality of preloaded tokens associated with the plurality of preloaded instructions; and one or more second processors coupled to the second memory units and configured, upon executing the one or more second instructions, to: receive the token; match the token to a preloaded token of the plurality of preloaded tokens, wherein the preloaded token is associated with a preloaded instruction of the plurality of preloaded instructions that matches the instruction; determine, based on the match, the preloaded instruction; and perform the preloaded instruction, wherein the token is devoid of the instruction and the preloaded instruction; wherein the one or more first processors of the controller are further configured to: following transmission of the token, generate a new token for association with the instruction, wherein generation of the new token causes the token to be obsolete; determine the instruction to be performed again by the remote device; determine the new token associated with the instruction; and transmit the new token to the remote device, wherein the one or more second processors of the remote device are further configured to: following receipt of the token, generate a new preloaded token for association with the preloaded instruction, wherein generation of the new preloaded token causes the preloaded token to be obsolete; receive the new token; match the new token to the new preloaded token; determine, based on the match, the preloaded instruction again; and perform the preloaded instruction again.
