Skill-based Matchmaking
Skill-based matchmaking (SBMM), also referred to as matchmaking ranking (MMR), is a form of matchmaking dependent on the relative skill level of the players involved. History A common rating system in chess is the Elo rating system, developed by Arpad Elo. Former International Chess Federation president Florencio Campomanes described it as an "inseparable partner to high-level chess". In 2006, Microsoft researchers proposed a skill-based rating system using Bayesian inference and deployed it on the Xbox Live network, then one of the largest deployments of a Bayesian inference algorithm. The researchers were displeased with the ranking system in the beta of ''Halo 2'' (2004). By the time ''Halo 2'' launched, it was using TrueSkill. The term skill-based matchmaking first appeared in a 2008 interview with game designer John Carmack in which he emphasized its importance in ''Quake Live'' (2010). Upon setting up an account with id Software, the game will ask the player for their skill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matchmaking (video Games)
In multiplayer video games, matchmaking is the process of connecting players together for online play sessions. Playlists Playlists are automatically managed streams of online play sessions that players can join and leave at will. A set of predefined rules is used to determine the configuration of each session without the need for human input. Games will normally offer a choice of themed playlists (e.g. teams or solo, quirky rulesets, etc.) to suit different tastes or moods. Since playlists are handled by servers controlled by the game's developer, it is possible for them to be changed over time. When a player selects a playlist, they join a pool of other people who have made the same choice. The playlist server then either connects them to an existing session or creates a new one. Parties Parties are groups of players who are treated as a single entity by matchmaking systems. A party can skip from session to session without its players becoming separated from each other.

Network Latency
Network delay is a design and performance characteristic of a telecommunications network. It specifies the latency for a bit of data to travel across the network from one communication endpoint to another. It is typically measured in multiples or fractions of a second. Delay may differ slightly, depending on the location of the specific pair of communicating endpoints. Engineers usually report both the maximum and average delay, and they divide the delay into several parts: * Processing delay time it takes a router to process the packet header * Queuing delay time the packet spends in routing queues * Transmission delay time it takes to push the packet's bits onto the link * Propagation delay time for a signal to propagate through the media A certain minimum level of delay is experienced by signals due to the time it takes to transmit a packet serially through a link. This delay is extended by more variable levels of delay due to network congestion. IP network delays can ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ping (video Games)
In computers, lag is delay ( latency) between the action of the user (input) and the reaction of the server supporting the task, which has to be sent back to the client. The player's ability to tolerate lag depends on the type of game being played. For instance, a strategy game or a turn-based game with a slow pace may have a high threshold or even be mostly unaffected by high lag. A game with twitch gameplay such as a first-person shooter or a fighting game with a considerably faster pace may require a significantly lower lag to provide satisfying gameplay. Lag is mostly measured in milliseconds (ms) and may be displayed in-game (sometimes called a lagometer). The most common causes of lag are expressed as ping time (or simply ''ping'') and the frame rate (fps). Generally a lag below 100 ms (10 hz or fps) is considered to be necessary for playability. The lowest ping physically possible for a connection between opposite points on Earth crossing half of the planet is 133 ms. ...
