Wavelength add-drop switching using tilting micromirrors
TL;DR: In this paper, a single-mode optical fiber switch which routes individual signals into and out of a wavelength multiplexed data stream without interrupting the remaining channels is described, and the total fiber-to-fiber insertion loss for the packaged switch is 5 dB for passed signals and 8 dB for added and dropped signals, with 0.2 dB polarization dependence.

Tiny Tera: a packet switch core
TL;DR: Tiny Tera as mentioned in this paper is an input-buffered switch, which makes it the highest bandwidth switch possible given a particular CMOS and memory technology. But it does not support multicasting.

Low-cost scalable switching solutions for broadband networking: the ATLANTA architecture and chipset
TL;DR: The ATLANTA/sup TM/ switching architecture as discussed by the authors uses an innovative structure with ingress and egress buffers, where selective backpressure is applied from the fabric to the ingress cards, achieving "sharing" of the distributed buffers and buffer utilization comparable with a centralized shared memory switch.
