Taking Halo 2 to Xbox Live

An anonymous reader writes "In this new interview, Bungie Studios engineering lead Chris Butcher explains how his team took Halo 2 multiplayer battles to Xbox Live, with minimal glitches. Turns out there are a lot of clever tricks involved." From the article: "It's actually the same network model we used in Marathon back in the day, although Marathon had some bugs in it. The thing with this networking model is if there's a bug in the computer code where two machines could provide the same inputs but get different outputs, there can be problems. There are lots of different ways that could happen."
