Query: Demand Engineering: IP Network Optimisation Through Intelligent Demand
  Placement   Traffic engineering has been used in IP and MPLS networks for a number of
years as a tool for making more efficient use of capacity by explicitly routing
traffic demands where there is available network capacity that would otherwise
be unused. Deployment of traffic engineering imposes an additional layer of
complexity to network design and operations, however, which has constrained its
adoption for capacity optimisation. The rise of Software Defined Networks has
renewed interest in the use of traffic engineering approaches leveraging
centralised network controllers for capacity optimisation. We argue that future
networks can realise the network optimisation benefits of traffic engineering
without incurring additional network complexity through closer coupling between
the network and the applications and services using the network. This can be
achieved through leveraging a network- and traffic-aware controller to directly
influence where applications and services site or locate service instances,
i.e. which implicitly impacts the paths that the applications or services
traffic demands take through the network. We call this technique Demand
Engineering. Demand Engineering has the additional benefit of providing an
admission control capability, i.e. which can provide an assurance that network
SLAs can be met. In this paper we describe the concept of Demand Engineering,
give examples of its use and present simulation results indicating its
potential benefits. We also compare demand engineering to traffic engineering.
