Bungie explained in detail how Destiny 2’s networking will work compared to the first Destiny.
Many fans were concerned about Destiny 2 not using dedicated servers and sticking to the original networking setup from Destiny 1. However, Destiny 2 lead engineer, Matt Segur, explained how Destiny 2’s networking differs.
“Many are concerned by our announcement last week that Destiny 2 doesn’t have dedicated servers,” Segur explained. “While that’s useful shorthand, the full answer is more complex because Destiny has a unique networking model.”
“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.”
Segur concluded with why the developer chooses not to use the term “dedicated servers.”
” …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.”
