And what better way to celebrate than by exploring the network metaphors of the mice flows and the elephant flows, with associated conundrum beats, that are the locusts of the Ultra-Ethernet vs Infiniband plague, and struggle!

Indeed, mice flows alone can be readily handled by the jungle of cables and switches that forms a nurturing networking environment and ecosystem, but the appearance of elephants commonly leads to wanton trampling of their light-duty nesting abilities. In the Congolese fable then, the mice flows retort by congesting elephant trunks until the large beasts slow to a creepy crawl, starve, and pass away … an approach that unfortunately satisfies only the mice. The Indian fable is more of a win-win though, with elephants agreeing to spray their herd packets around mice flow nests (rather than crush ’em), and mice flows eventually helping to decongest elephant flows, by cutting the large nets in which malicious hunters of computational performance parables had cunningly trapped them.

The beautiful moral of this allegoric rendering of the philosophical underpinnings of Ultra-Ethernet couldn’t be any clearer: A network friend in need, is a network friend indeed. Might this fundamental principle guide the adoption of 800 Gb/sec interconnects! 8^p
