The current incremental approach to lower latency and increase capacity will soon reach the end of the road. The reason for this has been known for some time and is stated in RFC 1925 clause 2:
“(2) No matter how hard you push and no matter what the priority, you can’t increase the speed of light.”
Our research has finally been able to circumvent this boundary by the development of zero-latency network paths. – RFC5984 Introduction
New and exciting moves are a foot to minimise latency in networks, reducing transmission delay, and finally making it possible for connections on the other side of the world to truly feel like they are participating on the LAN.
