Coordination without a center.

Delivering a response incrementally as it is produced rather than all at once when complete.
Networks & Distribution·17 connections
A guarantee that replicas converge given no further updates, without guaranteeing when.
Networks & Distribution·16 connections
An encrypted tunnel that presents a remote network as local, and the narrow set of things a commercial one actually hides.
Cryptographic attestation of an originating telephone number, and why spoofed calls survive it.
Networks & Distribution·14 connections
The browser standard for direct peer connections carrying audio, video, and arbitrary data.
Networks & Distribution·12 connections
An architecture where participants communicate directly rather than through a central server.
Networks & Distribution·11 connections
A CDN answers requests from servers near the requester, trading a single origin for many cached edges.
Networks & Distribution·10 connections
A SIM soldered into the device and provisioned over the air, with profiles downloaded rather than cards swapped.
IPv6 exists mainly to end address scarcity, with a large enough space that per-device NAT becomes optional.
Networks & Distribution·8 connections
A load balancer spreads requests across many backend instances, turning "one server" into "one address."
TCP guarantees ordered, reliable delivery at the cost of latency; UDP delivers packets fast with no such promise.
A data structure whose replicas can be edited independently and always converge without coordination.
Networks & Distribution·7 connections
The small coordination service peers use to find each other before connecting directly.
A webhook is an HTTP callback a service pushes to you when an event happens, inverting who initiates the request.
Anycast announces the same IP address from many locations and lets normal routing send each client to the nearest one.
Networks & Distribution·6 connections
An API gateway is the single front door to a set of backend services, handling cross-cutting policy once instead of per-service.
Latency is how long a packet takes; jitter is how much that time varies — and the second often matters more.
Zero trust authenticates and authorizes every request individually, treating network location as no proof of anything.
Backpressure is a slow receiver telling a fast sender to hold up, so a queue grows on purpose instead of by accident.
Networks & Distribution·5 connections
A circuit breaker stops calling a failing dependency, converting slow repeated failures into a fast, cheap one.
NAT traversal is the set of tricks two devices behind separate routers use to open a direct connection anyway.
QUIC rebuilds reliable, multiplexed transport on top of UDP so one lost packet stops blocking unrelated streams.
DNS over HTTPS wraps DNS lookups in encrypted HTTPS requests, hiding query contents from anyone but the resolver.
Networks & Distribution·4 connections
Rate limiting caps how often a client can act, protecting shared capacity by rejecting or delaying the excess.
Multicast sends one stream to a group of subscribed receivers at once, letting the network fan it out instead of the sender.
