| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The routing and spectrum allocation (RSA) problems need to be solved when we transmit some demands in an elastic optical network. This research deals with static RSA problems for anycast transmission which is one-to-one-of-many transmission in inter-datacenter networks. Two static RSA optimization models are considered. One is minimizing the maximum number of spectrum slots needed to allocate the given demands. The other is maximizing the traffic volume of demands served under the given spectrum slot number. For the both models, several greedy-type algorithms are investigated. We conducted computational experiments to confirm greedy-type algorithmic behaviors by each of selecting route criteria and by each of demand ordering policies. In our experimental results, the path selection criterion was important in the minimax slot number model and we conclude to have to select a shorter path under some slot conditions. In the maximum traffic volume model, there was no dominant of greedy-type algorithms. The best path selection criterion and the best demand ordering policy depended on the network and the traffic congestion level. | |
