Latency is not a new problem in networking. Application developers have also figured out clever ways of working around network latency problems, but there are limits to what can be done. Over the last few decades network managers have focused on adding bandwidth and reducing the network outages. How latency is measured.

Today, the internet (like most digital infrastructure in general) relies heavily on the security offered by public-key cryptosystems such as RSA, Diffie-Hellman (DH), and elliptic curve cryptography (ECC). But the advent of quantum computers has raised real questions about the long-term privacy of data exchanged over the internet.
