[AFMUG] Ultra low latency PTP

Anybody here up to date on current ultra low latency licensed PTP gear? Like in HFT networks. Trying to round up the current players. -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com

All the licensed gear I know of is full duplex, and should have near wire speed latency. The latency should be proportional to the link distance. bp On 9/1/2020 7:36 AM, Caleb Knauer wrote: Anybody here up to date on current u

There is a whole other class of low-latency wireless gear. FEC is removed. ARQ is nowhere to be found. The radios are optimized so that the data spends as few picoseconds as possible in the radio. - Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Broth
