Abstract
A photonic label switching router (PLSR) of which the photonic label
processing is based upon optical code correlation, is investigated. To resolve
the electronic router's bottleneck in current Internet protocol (IP) over
wavelength division multiplexing (WDM) networks, we will envision IP over
photonic networks in which the PLSRs totally replace the electronic routers.
The architectures of PLSR including the photonic label processing,the photonic
label swapping, and the optical switching and their optical implementations
are studied. Results of proof-of-concept experiments for the photonic label
processing and photonic label swapping will confirm the feasibility to attain
the target performance: the throughput of 100 Tb/s at least, the processing
speed around 10 Gpacket/s, and the number of label entries up to 10
k.
