Optimizing size of protocol communication in a vehicle internal networks

A system for reducing size of a intercepted messages transmitted via at least one wired communication channel of a vehicle, comprising:

• a program store storing a code;
• and
• at least one processor of a vehicular device coupled to the program store for executing the stored code, the code comprising:
• code instructions to receive at least one of a plurality of messages intercepted by at least one device adapted to monitor messages transmitted via at least one wired communication channel of a vehicle, the at least one device is a passive receiver-only device adapted to monitor the messages transmitted while incapable of altering transmission signals of the at least one wired communication channel;
• code instructions to apply at least one trained machine learning model to identify at least one of a plurality of data patterns in the at least one message,
• code instructions to adjust the at least one message by replacing the at least one identified data pattern with a respective predefined lossless representation having a reduced size compared to the at least one identified data pattern, wherein the at least one identified data pattern includes a time stamp indicating a timing of transmission of the at least one message, and wherein the adjusted time stamp is adjusted according to a transmission time of the at least one message;
• and
• code instructions to transmit the at least one adjusted message to a remote system via at least one upload communication channel,
• wherein the at least one machine learning model is trained with a plurality of training messages to identify the at least one data pattern in at least one field of the at least one message, the at least one field is a member of a group consisting of:
• a message identifier, an originating device identifier, a destination device identifier, the time stamp, a payload size indicator, a payload, a metadata and a protocol related field.
