Persisting graphics structures across client change in graphics remoting environment

A computer readable medium including instructions that, when executed by a processing system, cause the processing system to perform a method comprising:

• receiving, at a server, one or more hashes from a client, each of the hashes representing a graphics structure maintained by the client;
• generating, at the server, a first hash from a graphics structure according to a hash algorithm, the graphics structure being generated from an application hosted within the server and representing a display output of the application;
• determining, by the server, whether there is an existing hash from the one or more hashes received from the client that matches the first hash;
• and
• transmitting, from the server, the first hash to the client without sending the graphics structure if there is an existing hash matching the first hash, wherein the first hash is used by the client to identify a graphics structure maintained by the client for rendering a display of the client.

A system, comprising:

• a processor;
• and
• a memory coupled to the processor for storing instructions, which when executed by the processor, cause the processor to
• receive, at the system as a server, one or more hashes from a client, each of the hashes representing a graphics structure maintained by the client,
• generating, at the server, a first hash from a graphics structure according to a hash algorithm, the graphics structure being generated from an application hosted within the server and representing a display output of the application,
• determining, by the server, whether there is an existing hash from the one or more hashes received from the client that matches the first hash, and
• transmitting, from the server, the first hash to the client without sending the graphics structure if there is an existing hash matching the first hash, wherein the first hash is used by the client to identify a graphics structure maintained by the client for rendering a display of the client.

A machine-implemented method for persisting graphics structures, the method comprising:

• transmitting one or more hashes from a client to a server, each of the hashes representing a graphics structure maintained locally by the client;
• receiving, by a rendering agent of the client, a hash representing a graphics structure from the server, the graphics structures representing a display output of an application hosted by the server and accessed from the client;
• identifying, by the rendering agent, a graphics structure from one or more graphics structures maintained by the client based on the hash received from the server;
• and
• rendering, by the rendering agent, the identified graphics structure to a display of the client.
