Abstract

A rendering system includes a command server and a plurality of rendering servers. The command server receives a screen transmission request from the client terminal. The command server evaluates, for each of the plurality of rendering servers, at least one of a number of connected terminals, an average transmission rate, a GPU operation rate, a congestion status, and a length of a transfer path to the client terminal. The command server specifies, based on evaluation results, at least one of the plurality of rendering servers to render a screen to be transmitted to the client terminal.

First claim

What is claimed is:

1. A rendering system, comprising:
a command server that, based on information received from a client terminal, outputs a rendering command for a screen; and
a plurality of rendering servers configured to perform rendering of the screen in accordance with the rendering command output from the command server and transmit the screen to the client terminal, wherein
the command server comprises a first memory and a first processor, the first memory storing a first program, the first processor, by reading the first program, configured to cause the command server to perform first operations including:
receiving a screen transmission request from the client terminal;
evaluating, for each of the plurality of rendering servers, at least one of a number of connected terminals, an average transmission rate, a GPU operation rate, a congestion status, and a length of a transfer path to the client terminal; and
specifying, based on evaluation results of the evaluating, at least one of the plurality of rendering servers to render a client screen to be transmitted to the client terminal,

wherein the screen transmission request is received by the command server in a process during which the command server repeatedly performs the first operations in accordance with frame updates of a game screen.

2. The rendering system according to claim 1 ,
wherein each rendering server of the plurality of rendering servers is associated with a region in which the rendering server is arranged, and
wherein rendering servers that are associated with a client region, in which the client terminal is present, are specified as the at least one of the plurality of rendering servers.

3. The rendering system according to claim 1 ,
wherein the first operations further include:
obtaining a load state of rendering resources on each of the at least one of the plurality of rendering servers; and
outputting the rendering command to a rendering server that has loaded at least some of rendering resources necessary when performing rendering of the client screen, out of the at least one of the plurality of rendering servers.

4. The rendering system according to claim 1 , wherein
the at least one of the plurality of rendering servers comprises a second memory and a second processor, the second memory storing a second program, the second processor, by reading the second program, configured to cause the at least one of the plurality of rendering servers to perform second operations including:
receiving the rendering command and transmission destination information that indicates the client terminal;
generating the client screen by performing rendering processing based on the rendering command; and
transmitting the client screen to the client terminal based on the transmission destination information.

5. A command server that, based on information received from a client terminal, outputs a rendering command for a screen to a rendering server out of a plurality of rendering servers, the command server comprising:
a memory and a processor, the memory storing a program, the processor, by reading the program, configured to cause the command server to perform operations including:
receiving a screen transmission request from the client terminal;
evaluating, for each of the plurality of rendering servers, at least one of a number of connected terminals, an average transmission rate, a GPU operation rate, a congestion status, and a length of a transfer path to the client terminal;
specifying, based on evaluation results of the evaluating, at least one of the plurality of rendering servers to render the screen to be transmitted to the client terminal; and
outputting the rendering command to the rendering server out of the at least one of the plurality of rendering servers,

wherein the screen transmission request is received by the command server in a process during which the command server repeatedly performs the operations in accordance with frame updates of a game screen.
