Rendez-Vous lives on at Ubisoft, as their Montreal studio has continued to add features to it. Ubisoft later acquired Quazal Technologies in 2010. NEX actually began its life as Quazal Technologies Inc.’s Rendez-Vous, which started development all the way back in 2003. (NEX actually has its own peer-to-peer networking library independent of pia called VSocket, but I don’t think any game uses it?) Pia has built-in support for NEX’s matchmaking and NAT traversal features, making it easier for developers who are already using pia to implement online play. NEX handles matchmaking for peer-to-peer sessions, NAT traversal (helping people behind firewalls and/or routers with getting connected to others), rankings, and data storage. NEX is a two-part system comprising of a game server and a library containing APIs which game developers use to communicate with the server. Each Switch has its own line of communication to every other console in the session.īut how do other people find each other’s sessions? The Return of NEX This group of systems connected together using pia is called a “session”. This means that instead of one server having a “one-on-one conversation” with every Nintendo Switch console to exchange information, all of the consoles communicate directly with each other. It implements network features based on a “peer-to-peer” architecture, unlike the traditional “client-server” model. Pia is a library developed by Nintendo which makes creating networking features for games easier. You may want to keep it open to cross-reference some concepts that I will mention. You don’t need to know every single thing, but knowing the basics goes a long way. I will not be explaining everything here otherwise this post would be a million words long. Please have a look over PCGamer’s excellent netcode overview if you aren’t familiar with netcode concepts and terms. Let’s go over some concepts and terminology you will need to know to understand what I am talking about. It might be good to skim the next few sections for a refresher, however. If you are already familiar with those articles, you may skip to “Synchronization”. Note: The next few sections consist of content from my previous articles about the Splatoon 2 netcode and how Splatoon 2’s ranking system works with some edits.
