Patent ID: 8761167

Claim:
A method for a processing module of a computing device to execute a list range request operation, the method comprises: generating, by the processing module, a payload section of a dispersed storage network (DSN) frame regarding the list range request operation by: generating a start slice name field of the payload section to include a start slice name of a slice name range; generating an end slice name field of the payload section to include an end slice name of the slice name range; and generating a maximum response count field of the payload section to include a maximum slice name response count; and generating, by the processing module, a protocol header of the DSN frame by: generating a payload length field of the protocol header to include a payload length that represents a length of the payload section; generating an operation code field to indicate the list range request operation, wherein the list range request operation requests a list of slices names corresponding to a plurality of stored encoded data slices associated with slice names within the slice name range; generating remaining fields of the protocol header; and sending, by the computing device, the DSN frame to a storage unit of the DSN, where the DSN frame is requesting that the storage unit respond with a list of slice names that correspond to encoded data slices that are stored by storage unit and that have a slice name between the start slice name and the end slice name.
