We consider the problem of serving dynamic traffic in a spectrum flexible optical network, where the spectrum allocated to an end-to-end connection varies dynamically with time so as to follow the required source transmission rate. In the proposed framework, each connection is assigned a route and is allocated a reference frequency over that route, using an appropriate Routing and Spectrum Allocation (RSA) algorithm, but the spectrum it utilizes around the reference frequency is allowed to… CONTINUE READING
