This page describes what’s planned for INET in the future.
Update the ethernet model to support frame preemption.
Add an interface representing physical clocks enabling a common infrastructure for clock sync protocols.
As for the not-so-near future (potentially in a later major version), we are considering some nontrivial changes:
Factor out the base infrastructure from INET so we would have a subset of components that could be separately supported. Protocol specific code should be avoided in this codebase.
