Abstract
The present disclosure relates to packet-aware fault tolerance methods of virtual machines applied to cloud services. One such method includes using a primary input processing unit to receive an uploaded packet and replicating the uploaded packet to a backup input processing unit. The method can further include utilizing a primary execution unit to operate the uploaded packet to generate an output packet, which is then transmitted to a processing unit. A backup execution unit can be used to operate the uploaded packet to generate a backup output packet. The backup output packet can be transmitted to a backup processing unit. A fault-tolerance control component can receive the primary output packet from the primary output processing unit. The primary fault-tolerance control component can be used to compare a primary packet checksum of the primary output packet is consistent with a backup packet checksum.
