Data Mapping and Sorting Method in Network Communication

A method of mapping data among intelligent electronic devices (IEDs) in a network communication environment, said IEDs adapted to communicate the data in the form of data frames having time stamped data associated therewith, comprising the steps of:

• transmitting data in the form of a plurality of input data frames to an IED;
• receiving at least one of the input data frames, wherein each of the input data frames includes at least one input data slot associated therewith;
• correlating a measured arrival time of a first received input data frame;
• initiating a time interval from the measured arrival time wherein subsequent input data frames are to be received;
• receiving the input data frames during the time interval;
• sorting the input data frames received within the time interval based on time stamp data;
• determining whether the input data slots are unavailable or missing;
• mapping output data slots to form respective output data frames from the respective sorted input data slots using a mapping table stored in the IED;
• and
• transmitting the respective output data frames to another IED.

A method of mapping data among intelligent electronic devices (IEDs) in a network communication environment, said IEDs adapted to communicate the data in the form of data frames, some of the data frames having time-stamped data associated therewith, comprising the steps of:

• transmitting data in the form of a plurality of input data frames to an IED;
• receiving at least one of the input data frames, wherein each of the input data frames includes at least one input data slot associated therewith;
• correlating a measured arrival time of a first received input data frame;
• initiating a time interval from the measured arrival time wherein subsequent input data frames are to be received;
• using a sorting by time stamp data method upon receipt of the first input data frame with a time stamp before the expiration of the time interval;
• using a sorting by measured arrival time method upon expiration of the time interval without detection of time stamp in the first input data frame;
• determining whether the input data slots are unavailable or missing;
• mapping output data slots to form respective output data frames from respective sorted input data slots using a mapping table stored in the IED;
• and
• transmitting the respective output data frames to another IED.

The method of 15, wherein the sorting by time stamp data method further comprises the steps of:

• correlating a measured arrival time of the first received input data frame;
• initiating a time interval from the measured arrival time wherein subsequent input data frames are to be received;
• receiving input data frames during the time interval;
• and
• sorting the input data frames received within the time interval based on time stamp data.
