Implementation of an OBS access node supporting multiple services

Network operators want to deliver multiple services to the end customers. This leads to the need of efficient transport of data using optical network technologies. OBS is a promising technology for metro networks, where the operator can locate their servers to provide services such as video, backup or PC virtualization. These services are competing for shared network bandwidth when running in parallel. This work develops an FPGA-based access edge node, which operates with multiple QoS applications. This paper describes the architecture of the design as well as the behaviour of the implemented solution.
