Abstract

The protocol scheme of a destination or receiving station is identified by a source or sending station in order to permit automatic reformatting of the source data into a compatible format and protocol scheme before transmission is initiated. The destination protocol is logged in the source system so that the protocol can thereafter be determined by destination address. The scheme is also capable of determining the protocol and format of the sending station, selecting the appropriate protocol and converting the data to a compatible format.

Claims

1. A method for transmitting source data generated at a source system formatted with a source data format and protocol to a remote destination system which may require a different, incompatible protocol, the method comprising the steps of:

a. determining at the transmitting source the destination protocol;

b. checking the compatibility of the source data and the requirements for the destination data;

c. converting at the transmitting source the source data to a compatible data for the remote destination system if the source data and the requirements for the destination data are not compatible; and

d. initiating transmission of the converted source data in the compatible protocol requirements.

2. The method of claim 1, including the step of logging the destination protocol in the source system once the destination protocol is determined.

3. The method of claim 2, further including the step of using the log to select data format and transmission.

4. The method of claim 3, further including the step of updating the log automatically if the use of the logged information does not permit transmission.

5. The method of claim 3, further including the step of automatically determining the data format and protocol of the destination station when no compatible entry is present in the log.

6. The method of claim 3, wherein the logging steps includes creating a data base at the source system wherein the data base identifies the destination protocol by the destination address.

7. The method of claim 6, wherein the data base includes the electronic address for the destination system, and the protocol, format and parameters for the destination system.

8. The method of claim 7, wherein the data base includes a password for the destination system.

9. The method of claim 1, further including the step of initiating a send signal to the destination system between steps "a" and "b", and further including the step of interrupting transmission between steps "b" and "c" only if either or both of the following conditions are present:

a. the source and the destination protocol are incompatible; and

/or

b. the source data and the destination data are incompatible.

10. The method of claim 1, further including a protocol library and the method including the step of making a protocol decision for the destination system based on the protocol library.
