A New Traffic Engineering Algorithm to Simplify Network in Optical Switching Network

Abstract

With the explosive growth of optical network dimensioning [1] and the call of traffic, the network traffic is becoming more and more imbalanced. When some links are busy and have congestion, some others are idle for long time. This paper proposes a theory which simplifies a complex optical network into an equivalent easy one using the bandwidth of the optical link. and we call this theory TDBB. For the large capacity optical switching network node 1000×1000,divided in two level :the ms level 32×32 optical switching and ns level 32×32 using time division multiplexing in subcarrier wave. Every subcarrier [2] has 10G bandwidth. So we have 10T in single wave ,200T in single fiber. 10P capacity of total 50 ports. which is to say this theory can work for TE project in optical switching network which has more than 10pbs large capacity.
