System, method and computer readable medium for communication of encoded messages
A message encoding specification and implementation where a receiver of an encoded message determines if the message can be decoded. If the receiver can decode the message, it does so and continues processing the message. If the receiver cannot decode the message, it returns a distinguished failure message to the sender, expecting the sender to resend the message using a different encoding scheme. When a sender receives the distinguished failure message that the receiver cannot decode the message, the sender encodes the message using an alternate encoding scheme, if one is available, and resends the message. The process continues until the sender has tried all available encoding schemes. If a sender exhausts the collection of available encoding schemes without finding one the receiver can successfully decode, the sender treats the failure as an error.
1. A method, comprising:
transmitting a message encoded using an initial encoding scheme to a receiver;
encoding the message, without reference to an application origination the message, using an alternative encoding scheme in response to receiving a failure notification from the receiver indicating a failure to decode the message encoded using the initial encoding scheme; and
transmitting the message encoded using the alternative encoding scheme to the receiver;
wherein failure notification is configured to identify the alternative encoding scheme.
2. The method according to claim 1 , wherein a header of the message encoded using the initial encoding scheme comprises an indication of the initial encoding scheme.
3. The method according to claim 1 , wherein the message encoded using the alternative encoding scheme comprises a header encoded using an encoding scheme common to a sender and the receiver.
4. The method according to claim 1 , comprising transmitting the message encoded by successive alternative encoding schemes to the receiver until the receiver successfully decodes the message.
5. The method according to claim 1 ,
wherein the failure notification is configured to indicate at least one preferred encoding scheme; and
wherein encoding the message using the alternative encoding scheme comprises determining the at least one preferred encoding scheme from the failure notification and encoding the message using the at least one preferred encoding scheme.
6. The method according to claim 1 , comprising defining a common encoding scheme that is common to a sender and the receiver.
7. The method according to claim 6 , comprising decoding the common encoding scheme from the failure notification.
8. The method according to claim 6 , comprising encoding a header of the message using the common encoding scheme.
9. The method according to claim 1 , wherein the failure notification comprises a description of the failure, a list of encoding schemes supported by the receiver, or a combination thereof.
10. A system, comprising:
a memory device configured to store instructions; and
a processing device configured to execute the instructions stored in the memory device to:
encode a message from an application using an initial encoding scheme;
transmit the message encoded using the initial encoding scheme to at least one receiver computer;
receive a failure notification from the at least one receiver computer indicating a failure of the at least one receiver computer to decode the message encoded using the initial encoding scheme;
encode the message using an alternative encoding scheme without reference to the application; and
transmit the message encoded using the alternative encoding scheme to the at least one receiver computer.
11. The system according to claim 10 , wherein the failure notification is configured to indicative that the initial encoding scheme is not implemented in the at least one receiver computer.
12. The system according to claim 10 , wherein the failure notification identifies the alternative encoding scheme.
13. The system according to claim 10 , wherein the failure notification is configured to identify at least one encoding schemes implemented on the at least one receiver computer.
14. The system according to claim 10 , wherein the failure notification comprises a description of the failure, a list of encoding schemes supported by the receiver, or a combination thereof.
15. A non-transitory computer-readable medium comprising computer-executable instructions stored thereon that, when executed by a processing device, cause the processing device to:
receive a message from an application;
encode the message using an initial encoding scheme;
transmit the message encoded using the initial encoding scheme to a receiver;
receive a failure notification from the receiver in response to the message encoded using the initial encoding scheme;
re-encode the message using an encoding scheme indicated in the failure notification without sending the failure notification to the application; and
retransmit the message to the receiver.
16. The non-transitory computer-readable medium of claim 15 , wherein the failure notification comprises a description of the failure, a list of encoding schemes supported by the receiver, or a combination thereof.
