Abstract
To utilize network resources effectively and guarantee the system reliability in Internet exchanges (IXs) in
the future, the use of photonic IXs that employ optical cross connects and generalized multiprotocol label switching
is considered. This paper presents a theoretical and experimental study of link-capacity adjustment for a photonic
IX employing a statistical-decision method for traffic monitoring. We present parameter estimation of the
statistical-decision method in detail considering the traffic characteristics in IXs. Then, experiments on the
link-capacity adjustment are presented. The first experiment shows the link-capacity adjustment of an optical path
to evaluate path addition from one path to two and path deletion from two optical paths to one. The second
experiment shows the link-capacity adjustment using multiple paths. We confirmed that there is no packet/frame loss
in either experiment during the transmission of demo traffic, which simulates daily traffic changes.
