Paper Abstract

How to reduce the interdomain routing instability in multidomain optical networks is a burning issue of the day. An approach called active choke of interdomain routing (ACIR) is proposed to decrease the instability caused by temporary node overload. In this approach, when the network load increases to a certain value, the traffic requests without a minimum number of spanned domains are rejected directly or with a fixed or floating probability, while the rest are accepted. With the wavelength continuity constraint, numerical results on two network topologies demonstrate that the ACIR approach provides better blocking performance during heavy traffic and lower load at both nodes and domain controllers.
