An edge server of an infrastructure service establishes a transport connection in user space with a client and in accordance with a transport layer network protocol. The edge server receives a packet over the transport connection with the client that comprises a request for an object. If the edge server cannot serve the object, it forwards the request to a cluster server with an intent indicated for the cluster server to reply directly to the client. The cluster server receives the forwarded request and determines whether to accept the intent indicated by the edge server. If so, the edge server conveys instructions to the cluster server for sending at least a portion of the object directly to the client. The cluster server then sends at least the portion of the object to the client in accordance with the instructions.

Direct server reply for infrastructure services

Improper communication using modified software is inhibited without checking game data itself. A system according to one embodiment realizes provision of an online game to a login user with HTTP communication between the server and the client terminal. The HTTP communication includes transmitting, by a terminal device, a HTTP request to which a sequence number of the terminal side is attached; checking, by the server, validity of the HTTP request based on comparison between the sequence number of the login user stored in the server and the sequence number attached to the HTTP request; updating, by the server, the sequence number according to a predetermined update rule; transmitting, by the server, a HTTP response; and updating, by the terminal device, the sequence number in the terminal device according to the predetermined update rule.

System and method for providing user with services

Improper communication using modified software is inhibited without checking game data itself. A system according to one embodiment realizes provision of an online game to a login user with HTTP communication between the server and the client terminal. The HTTP communication includes transmitting, by a terminal device, a HTTP request to which signature information generated based on the HTTP request and terminal-side key information is attached; checking, by the server, validity of the HTTP request based on comparison between the signature information attached to the HTTP request and signature information generated based on the HTTP request and the server-side key information of the login user; updating, by the server, the key information based on the HTTP request and the server-side key information; transmitting, by the server, a HTTP response; and updating, by the terminal device, the key information based on the HTTP request and the terminal-side key information.

A server according to an embodiment provides online games that send game screens more suitably for the throughput of a user terminal. In accordance with one aspect, the server can execute a game program including: a game progress module for progressing a game; a generation module for generating, at first time intervals, frame information containing a plurality of drawing commands to be executed on a terminal device to render one frame of a game screen in accordance with progression of the game; a determination module for determining whether to send the generated frame information to the terminal device; a compression module for compressing the generated frame information; a sending module for sending to the terminal device the compressed frame information to be sent; and a request module for requesting drawing execution time information from the terminal device at second time intervals.

Video game with decoupled render and display rate

One object of the present invention is to reduce the load on a server and reduce the communication traffic produced in providing online games. In accordance with one aspect, the server can execute a game program including: a game progress module for progressing a game; a generation module for generating, at first time intervals, frame information containing a plurality of drawing commands to be executed on a terminal device to render one frame of a game screen; a determination module for determining whether to send the generated frame information to the terminal device; a compression module for compressing the generated frame information; a sending module for sending to the terminal device the compressed frame information to be sent; and a request module for requesting drawing execution time information from the terminal device at second time intervals.
