🌐 Networking: Packets, Queues and TCP Congestion (2D)

Interactive 2D map of a packet-switched network: pick sender and receiver hosts, cut or restore links, drag nodes, and watch TCP Reno (or a fixed window) share links with UDP cross traffic while queues, drops, RTT and routing respond in real time.

ControlsFive preset topologies, TCP Reno or fixed-window sender, UDP cross traffic rate, selected-link bandwidth, delay, buffer size and random loss, routing metric (latency or hop count), playback speed, pause/step/skip; click hosts to set sender and receiver, click a link to select it (again to cut or restore), drag nodes.
