Documentation

Overview

Package mgrp implements interface-honed multicast UDP.

The Linux multicast API lets you join a multicast group on a specific interface, but doesn't disambiguate received traffic based on the receiving interface, leading to unexpected consequences in applications that care about the source of the traffic.
