Such additions provide carriers with routing choices, which usually increase risks but reduce costs.
Especially, techniques to help the application to do the right routing choices are much needed.
Especially during rush hour travel times and therefore routing choices might be different than during other times.
To this purpose, they propose that a central SDN controller gathers information from distributed gateways to optimally schedule inter-datacenter transfers based on per-chunk routing choices.
While the prospect of all these routing decisions taking place at once is daunting, it's important to remember that very few routing choices are made in real time.
Many recent green vehicle routing papers have presented mathematical models designed to minimize fuel consumption and the environmentally damaging carbon emissions in the routing decisions related to route choice, the load on the vehicle, and the speed.
Approximate traffic equilibrium conditions can be integrated within the parsimonious traffic models to develop regional routing strategies, while detailed route choice strategies can be incorporated at a later stage in a hierarchical framework.
The technical details for each cluster cover all of the key parameters relating to size, location, routing, technology choices, engineering and operation.
In this paper, we propose a new peer-to-peer DHT overlay design, HyPeer, that uses the "flexible-choice routing" principle to support multiple routing strategies, each driven by a different objective: fault tolerance, load balance, low latency.
