In terms of the growth rate, network capacity is slower than network traffic. To solve the mismatch between them, utilization
of available capacity can be maximized to provide “best-fit” service for emerging applications (e.g., eBanking, Peer-to-Peer
(P2P) file exchanges, etc.). To satisfy such a requirement, we propose a three-dimensional label scheduling algorithm (TD-LSA),
which is a distributed scheduling approach powered by central databases. In the proposal, all connections are provisioned
in three dimensions (i.e., space, time and wavelength) in a distributed way and uniquely identified by three-dimensional labels.
And in this way a three-dimensional connection is more robust than a single-dimensional connection because the three-dimensional
approach can avoid potential scheduling conflicts as much as possible by using central databases in a network. Thus, the central
databases can reduce bandwidth consumption and offer “best-fit” service for three-dimensional connections. Furthermore, in
order to further reduce bandwidth consumption and to match with a priority of traffic, K-least hop first path (K-LHPF) and a rescheduling mechanism are applied to our proposal. Simulation experiments demonstrate that our proposal achieves
the expected performance gain against existing alternates. |
