We show that optical packet switching (OPS) 5G networks without buffers in their switches are expected to offer applications that require reliable packet delivery [e.g., zero losses via transmission control protocol (TCP)] the following improvements, compared to what is offered by the state-of-the-art in electronic packet switching (EPS) networks: lower flow completion times, and thus higher throughputs...
We show by simulation that the throughput and delay of applications that require zero losses in 5G metropolitan networks are greatly improved by replacing current electronic packet switching (EPS) networks with optical packet switching (OPS) networks with bufferless switches (no RAM, no fiber-delay-lines) that do not implement any kind of circuit-switching. The reason is that the total lack of queueuing...
