In this lecture, we will look at the current protocol for discovering game servers and how to improve the protocol.  We will also look at ways we can group players with low latency to each other together in the same game session.


The REED server discovery algorithm is discussed in detail in [Armitage12].  [Manweller11] provides a highly detailed description of a study in latency measurement and estimation in mobile networks, with application to player matchmaking in mobile games.  The use of hierarchical clustering and QT clustering to match players are discussed in this context in the section on Grouping Agent.
