Rerouting in Advance Reservation Networks
The advance reservation of network connections is an area of growing interest and a range of service models and algorithms have been proposed to achieve various scheduling objectives, i.e., including optimization-based strategies and heuristic schemes. Now given the time-shifted nature of future requests, rerouting strategies have also been considered to improve resource allocation and carried loads. However, most existing rerouting schemes have focused on minimizing connection disruptions and have not considered further link load information. Along these lines, this paper develops novel rerouting strategies to improve connection scheduling in advance reservation networks.
