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?
