Abstract:
A method for distributed file transfers with high performance and reliability includes creating, on a first Trivial File Transfer Protocol (TFTP) server, a global cache, where the global cache is used to store up to a first portion of a data file. The method further includes storing, on the first TFTP server, in the global cache, one or more continuous data blocks that have exceeded a defined first request rate threshold, where the one or more continuous data blocks make up a subset of the data blocks of the first portion of the data file. The method further includes predicting, on the first TFTP server, a next data block in the data file to be stored in the global cache and in response to predicting the next data block, storing, on the first TFTP server, the next data block in the global cache.

Claim (Index 1):
A computer system comprising:\n one or more computer processors; one or more computer readable storage media; program instructions stored on the computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising: program instructions to create, on a first Trivial File Transfer Protocol (TFTP) server, a global cache, wherein the global cache stores up to a first portion of a data file, wherein the data file is divided into a plurality of portions, including the first portion, and wherein the plurality of portions are stored among a plurality of TFTP servers, including a second portion of the data file that is stored on a second TFTP server; program instructions to store, on the first TFTP server, in the global cache, one or more continuous data blocks that have exceeded a defined first request rate threshold, wherein the one or more continuous data blocks make up a subset of the data blocks of the first portion of the data file, and wherein the program instructions to store, in the global cache, the one or more continuous data blocks that have exceeded the defined first request rate threshold comprise:\n program instructions to monitor, on the first TFTP server, a request rate for a particular data block, \n program instructions to determine, on the first TFTP server, if the request rate for the particular data block exceeds the defined first request rate threshold, wherein the defined first request rate threshold is a configurable limit that defines when data blocks are to be added to the global cache, and wherein the defined first request rate is adapted to optimize a transfer rate and reduce reads from one or more hard drives, and \n program instructions to add, on the first TFTP server, the particular data block to the global cache based on the determining; \n program instructions to predict, on the first TFTP server, a next data block in the data file to be stored in the global cache, wherein the program instructions to predict the next data block comprise:\n program instructions to, upon adding a particular data block to the global cache, monitor, on the first TFTP server, the request rate of the next data block, wherein the next data block is the next logical block of the data blocks of the first portion of the data file following the one or more continuous data blocks stored in the global cache, and \n program instructions to, upon monitoring the request rate of the next data block, predict, on the first TFTP server, when requests for the next data block will be likely to exceed the defined first request rate threshold; \n program instructions to, in response to predicting the next data block, store, on the first TFTP server, the next data block in the global cache; program instructions to store, on the first TFTP server, multiple copies of the data blocks of the first portion of the data file on a plurality of TFTP servers to enable a high availability for reading one or more blocks in the global cache; program instructions to monitor, on the first TFTP server, the one or more continuous data blocks in the global cache to determine if the request rate for an end data block of the one or more continuous data blocks has fallen below a defined second request rate threshold, wherein the defined second request rate threshold is a configurable limit that defines when the one or more continuous data blocks in the global cache can be removed from the global cache; and program instructions to, in response to determining that the end data block of the one or more continuous data blocks has fallen below the defined second request rate threshold, remove, on the first TFTP server, the end data block from the one or more continuous data blocks stored in the global cache.
