Patent ID: 8625636

Claim:
A method for a processing module of a computing device to execute a checked write request operation, the method comprises: generating a payload of a dispersed storage network (DSN) frame regarding the checked write request operation by: generating a transaction number field of the payload to include a transaction number corresponding to the checked write request operation; and generating one or more slice payload sections, wherein a slice payload section of the one or more slice payload sections includes: generating a slice name field to include a slice name of one or more slice names corresponding to an encoded data slice of one or more encoded data slices; generating a last known slice revision numbering field to include a last known revision number of the slice name; generating a new slice revision numbering field to include a new revision number of the slice name corresponding to the checked write request operation; generating a slice length field to include a length of the encoded data slice; and generating a slice payload field to include the encoded data slice; and generating a protocol header of the DSN frame by: generating a payload length field of the protocol header to include a payload length that represents length of the transaction number field and length of the one or more slice payload sections; and generating remaining fields of the protocol header.
