Search Results for "protocol stack"

netstack is a userspace TCP/IP networking stack written in Go that implements core IPv4/IPv6 protocols with a focus on correctness, isolation, and testability. By running entirely in user space, it avoids kernel dependencies and can be embedded into sandboxes, virtualized environments, or custom appliances. Its architecture models NICs, link endpoints, route tables, and protocol engines as composable interfaces, enabling precise control over packet flow and easy mocking in tests. ...

...On BSD-derived systems such as OSX, we use tools like ipfw and pfctl to inject failure. On Linux, we use iptables and tc. Comcast is merely a thin wrapper around these controls. Windows support may be possible with wipfw or even the native network stack, but this has not yet been implemented in Comcast and may be at a later date. On Linux, Comcast supports several options: device, latency, target/default bandwidth, packet loss, protocol, and port number.
