| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a bandwidth design method considering failures in an IP network. When we design the link bandwidth, we need to consider rerouted traffic’s bandwidth by failures in order to avoid the traffic congestion. If we knew the point-to-point traffic matrix, we could easily obtain the required link bandwidth after failures, but it is generally difficult to measure traffic matrices in a large network. The proposed method does not need traffic matrix measurement; instead, it uses link load measurement before failures which is generally easy to measure. Then, the proposed method calculates the logical least upper bound of the bandwidth variation at each link by failures by using Linear Programming (LP). Simulation results show that the link bandwidth amount designed by the proposed method is close to the actually required amount, which needs traffic matrix measurement. Particularly, compared with the simple method which does not use LP, the proposed method achieves 50 % reduction in wasted bandwidth amount. Moreover, we show that relation of the average node degree and the wasted bandwidth amount: the wasted bandwidth amount decreases as the average node degree decreases. | |
