A game server switching method, applied to a game server switching system, the game server switching system comprising a load balancer, a network-layer access subsystem, a network-layer proxy subsystem, a game logic subsystem, and a role login management server, a communication connection being established between the load balancer and a game client, the load balancer being connected to the network-layer access subsystem, the network-layer access subsystem being connected to the network-layer proxy subsystem, the network-layer proxy subsystem being connected to the game logic subsystem, the game logic subsystem being connected to the role login management server, and the game logic subsystem comprising a first game server and a second game server, the first game server communicating with the game client by using the network-layer proxy subsystem, the network-layer access subsystem, and the load balancer; and the method comprising the following steps: determining, by the first game server based on a game data obtaining request sent by the game client, that the first game server does not store game data requested by using the game data obtaining request, and sending a route switching request message to the network-layer access subsystem by using the network-layer proxy subsystem; establishing, by the network-layer access subsystem, a communication connection between the network-layer access subsystem and the second game server based on the route switching request message, the second game server storing the game data requested by using the game data obtaining request; sending, by the first game server, a write-back request to the role login management server; sending, by the role login management server in response to receiving the write-back request, user role data to the second game server based on the write-back request; and sending, by the second game server after obtaining the user role data from the role login management server, the game data to the game client by using the network-layer proxy subsystem, the network-layer access subsystem, and the load balancer. a communication connection being established between the load balancer and a game client, the load balancer being connected to the network-layer access subsystem, the network-layer access subsystem being connected to the network-layer proxy subsystem, the network-layer proxy subsystem being connected to the game logic subsystem, the game logic subsystem being connected to the role login management server, and the game logic subsystem comprising a first game server and a second game server, the first game server communicating with the game client by using the network-layer proxy subsystem, the network-layer access subsystem, and the load balancer; and the method comprising the following steps: determining, by the first game server based on a game data obtaining request sent by the game client, that the first game server does not store game data requested by using the game data obtaining request, and sending a route switching request message to the network-layer access subsystem by using the network-layer proxy subsystem; establishing, by the network-layer access subsystem, a communication connection between the network-layer access subsystem and the second game server based on the route switching request message, the second game server storing the game data requested by using the game data obtaining request; sending, by the first game server, a write-back request to the role login management server; sending, by the role login management server in response to receiving the write-back request, user role data to the second game server based on the write-back request; and sending, by the second game server after obtaining the user role data from the role login management server, the game data to the game client by using the network-layer proxy subsystem, the network-layer access subsystem, and the load balancer. determining, by the first game server based on a game data obtaining request sent by the game client, that the first game server does not store game data requested by using the game data obtaining request, and sending a route switching request message to the network-layer access subsystem by using the network-layer proxy subsystem; establishing, by the network-layer access subsystem, a communication connection between the network-layer access subsystem and the second game server based on the route switching request message, the second game server storing the game data requested by using the game data obtaining request; sending, by the first game server, a write-back request to the role login management server; sending, by the role login management server in response to receiving the write-back request, user role data to the second game server based on the write-back request; and sending, by the second game server after obtaining the user role data from the role login management server, the game data to the game client by using the network-layer proxy subsystem, the network-layer access subsystem, and the load balancer.
