What must be implemented globally, by common agreement, is the format of the in/out tag in packets, and the semantics that out packets receive congestion indications first … The scheme can implement a wider range of services than just the expected capacity scheme.
Predictor: Clark, David D.
Prediction, in context:David D. Clark stated the following in a presentation at the MIT workshop on Internet Economics in March 1995: ”A goal for any mechanism that is implemented inside the network is that it be as general as possible, since it will take a substantial amount of time to get community consensus on the enhancement, as well as time to implement and deploy it. The mechanism proposed here, which is the discrimination between packets marked as in and out for congestion pushback at times of overload, has the virtue of being simple to implement and capable of supporting a wide range of policies for allocation of capacity among users. It allows providers to design widely differing service models and pricing models without having to build these models into all the packet switches and routers of the network … What must be implemented globally, by common agreement, is the format of the in/out tag in packets, and the semantics that out packets receive congestion indications first … The scheme can implement a wider range of services than just the expected capacity scheme. It can be used to implement essentially any service that the provider and subscriber agree to, subject to the assumption that the service is implemented by aggregating the traffic from all the users and treating the service assurance as a provisioning problem. We argue that since the Internet works reasonably well today on this basis, an improvement based on the same general approach will be sufficient to meet the next generation of needs.”
