Abstract:
|
This work addresses the offline problem of efficiently
planning network substrates joining geographically distributed
IT resource locations over high-capacity optical resources. Given
an already known set of virtual infrastructure demands to be
embedded over the network substrate, we present an iterative
optimization heuristic that appropriately embeds all virtual
infrastructure demands in order to minimize both the physical
substrate IT and optical resources needed to allocate them. For
this purpose, the heuristic arranges the demands in descending
order, based on the amount of resources they require. Then, it
processes all demands, one after another, optimally embedding
each one of them on the network substrate using Integer Linear
Programming (ILP) techniques. The performance of the
proposed heuristic is highlighted through illustrative results. |
