f5 load balancing methods

Excerpt from: Multiplayer Online game server architecture Http://wenku.baidu.com/view/aac987eae009581b6bd9eb8a.html MMORPG load Balancing mechanism 1. Static distribution of players to the server The average player is assigned to each server so that each server has the same number of players. The advantage of this approach is that the algorithm is simple, but the player moves on the map, so over tim

describes how to deal with nginx:3) ip_hashIp_hash technology in nginx can direct requests from an ip address to the same backend, so that a client and a backend under this ip address can establish a stable session, ip_hash is defined in upstream configuration:Upstream backend {Server 127.0.0.1: 8001;Server 127.0.0.1: 8002;Ip_hash;}Ip_hash is easy to understand. However, ip_hash is flawed because it can only be used to allocate backend ip addresses. in some cases, ip_hash cannot be used:1/nginx
