List range operation dispersed storage network frame

摘要

A method begins by generating list range requests. A list range request includes a payload section and a protocol header section. The payload section includes a start slice name field regarding a start slice name of a slice name range; an end slice name field regarding an end slice name of the slice name range; and a maximum response count field regarding a maximum slice name response count. The protocol header includes a payload length field that represents a length of the payload section and an operation code field to indicate the list range request operation. The list range request includes a request to provide a list of slices names corresponding to stored encoded data slices associated with slice names within the slice name range. The method continues by sending the range requests to storage units of the DSN.

1. 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 plurality of list range requests, wherein a list range request of the plurality of list range requests includes:
a payload section that includes:
a start slice name field of the payload section to include a start slice name of a slice name range;an end slice name field of the payload section to include an end slice name of the slice name range; anda maximum response count field of the payload section to include a maximum slice name response count; anda protocol header that includes:
a payload length field of the protocol header to include a payload length that represents a length of the payload section;an operation code field to indicate the list range request operation, wherein the list range request includes a request to provide a list of slices names corresponding to a plurality of stored encoded data slices associated with slice names within the slice name range; and sending, by the processing module, the plurality of list range requests to storage units of a dispersed storage network (DSN).
