WebRTC のようなリアルタイム通信で求められるのは「一部のノードに問題が起きても利用し続けられる」事だと考えています。 そのため時雨堂では自社製品である WebRTC SFU Sora にクラスター機能を搭載し、一つのノードに障害が起きた場合でも再接続を行えばすぐにまた利用できるような仕組みを実現しています。 2022 年 6 月にリリース予定の次のバージョンでは、クラスター機能を改善し、より障害に強く、さらにクラスターの運用コストを下げる仕組みを入れています。 まとめ 起動したら自動でクラスターを構築し始める スプリットブレインが発生し、クラスターの全ノード数に対して、参加しているノードが半数未満になったサブクラスターはすべての接続を受け入れなくなる 過半数のノードが参加しているクラスターに自動で再参加する スプリットブレインについて こちらがわかりやすいです。 https://docs.oracle.com/cd/E19787-01/820-6910/6ni73qiv8/index.html
