System and method for command tracking

Abstract

Embodiments of the present invention provide a system and method of command tracking that eliminates, or at least substantially reduces, the shortcomings of prior art systems and methods for command tracking. More particularly, embodiments of the present invention provide a system and method in which a command is assigned a unique identification. State information for the command (e.g., has the command been completed, has all the data associated with the command been received and other state information) can be associated with the unique identification and recorded. According to one embodiment, the state information can be stored in various tables that correspond to particular data transport protocols and/or devices. Because the state information for the command is associated with the unique identification in the tables, state information for the same command can be identified, even if the command changes data transport protocols.

         38 . A method of tracking commands between devices on a network comprising:
 providing a system comprising a routing device having a first controller operable to interface with a first data transport medium, a second controller operable to interface with a second data transport medium, a buffer and a processing unit coupled to the first controller, the second controller and the buffer, wherein the routing device further comprises a set of executable instructions, wherein the processing unit is operable to execute the set of instructions to perform the steps of;   receiving a command from a first device on the first data transport medium according to a first data transport protocol, wherein the command is intended for a target device operating according to a second data transport protocol;
 assigning the command a unique identification; and 
 recording state information for the command wherein the state information corresponds to the first data transport protocol and the second data transport protocol and the state information is associated with the unique identification.
