With it kind of boiling down to the fact that Destiny uses a wide range of networking technologies (including many a server) and that Destiny 2 will see an improvement in a number of areas over the original. Engineering Lead on Destiny 2 Matt Segur, answered a wide range of questions ranging from 'So why no dedicated servers?' through to 'With Destiny 2 coming out on PC, does peer-to-peer networking put players at risk of being cheated?'.
Bear in mind that you'll probably need to be a network engineer to fully grasp the system that will be in place, but it's a fascinating read none the less.
So why no dedicated servers?
Matt: Every activity in Destiny 2 is hosted by one of our servers. That means you will never again suffer a host migration during your Raid attempt or Trials match. This differs from Destiny 1, where these hosting duties were performed by player consoles and only script and mission logic ran in the data center. To understand the foundation on which we’re building, check out this Destiny 1 presentation from GDC. Using the terms from this talk, in Destiny 2, both the Mission Host and Physics Host will run in our data centers.
Wait, so we do have dedicated servers?
Matt: We don't use that term, because in the gaming community, “dedicated servers” refers to pure client-server networking models. Destiny 2 uses a hybrid of client-server and peer-to-peer technology, just like Destiny 1. The server is authoritative over how the game progresses, and each player is authoritative over their own movement and abilities. This allows us to give players the feeling of immediacy in all their moving and shooting – no matter where they live and no matter whom they choose to play with.
Why peer-to-peer? Are we trying to save money?
Matt: Nope! We've invested heavily in new server infrastructure for Destiny 2, including using cloud servers for gameplay for the first time. We really believe this is the best model for all of Destiny 2's varied cooperative and competitive experiences. Engineering will always involve tradeoffs and cost-benefit analysis, but as a team we’ve got no regrets about the unique technology we’ve built for Destiny 2.
With Destiny 2 coming out on PC, does peer-to-peer networking put players at risk of being cheated?
Matt: The PC platform poses unique security challenges for Destiny 2, but our security Ninjas have spent several years building a plan for how to engage with this new and vibrant community. We have a variety of top-secret strategies to ensure that the life of a cheater in Destiny 2 PC will be nasty, brutish, and short. And, regardless of what platform you play on, all changes to your persistent character are communicated directly to our secure data center with no peer-to-peer interference.
