Remotely change parameters values from the outside (like XCP)

Question

I am developing an application in C on an Embededd Linux platform.

I would like to have a way of setting values of variables (i.e.: parameters) from the outside (calibration protocol)

Example of a parameter would be the initial value of a counter keeping track of the uptime of the system. (Additionally, I would need to periodically save the current uptime value, storing it somewhere (e.g.: into a file) and loading the updated initial value when the application is started again.)

I had a brief experience with Embedded C programming of ECU communicating over CAN bus and there I used CCP protocol (XCP protocol over CAN bus) to update values of parameters.

I would like to have something similar to what I had with CCP, but on a more complex system (not just a bare-metal system, but a Linux OS) and by performing parameters update operations remotely (e.g.: with a UDP or TCP socket).

How can I achieve this? Is there some standard protocol to do this?

Thank you in advance.

Since XCP stands for "Universal Measurement and Calibration Protocol", you can implement on any communication layer (including ethernet with UDP or TCP socket).

Vector offers a great collection of documentation and examples: Vector XCP
