Hi Sam,
'context' is an object of neutron.context.Context which inherits
oslo_context.RequestContext.
When you see 'context' as a method signature like
router_added_to_agent(self, context, payload),
'context' is Context object.
oslo_messaging serializes the context object and sends to RPC consumer(s).
The serialization conveys the object content to a receiver.
In neutron case, the 'context' object is usually created from keystone
context [1]
or get_admin_context(_without_session) [2].
Does this answer to your question?
