Optical Interconnection Bidirectional Data Vortex Network: Architecture and Performance Analysis

Hardware implementation of contention aware optical switching node for data center networks

“…Multistage bidirectional optical network is a suitable candidate to sustain the huge internet traffic. The multistage network includes more than 10 000 port counts in which every source and destination node may have multiple paths . The data are transferred from source node to destination node by crossing multiple node and paths.…”

“…The data are transferred from source node to destination node by crossing multiple node and paths. It is obvious that the same node is accessed multiple times in the same time slot . Therefore, the contention should be resolved so that only one packet is processed in a time slot at any node.…”

Hardware implementation of optical switching node for data center networks

“…In the optical environment along with other bidirectional devices, such as Semiconductor Optical Amplifier (SOA), Erbium Doped Fiber Amplifier (EDFA), coupler, cross connects; optical bi-directional switch can also be connected in a network so as to have high throughput and capacity. 4 Owing to the optical bandwidth capacity and bidirectional capability, the number of port counts can be increased in both the directions. The wavelength routing is used in all optical passive networks to direct the packet to its desired destination.…”
