System for providing software application updates to multiple clients on a network

摘要

System for providing software application updates to multiple clients on a network including a server component and a client component. The version of the software application on the client component is compared with the version of the application stored on the server component to determine whether the client's version is outdated. If an update is necessary, a first data transmission channel is established between the client and server components and the client recursively works through each file of the software application and sends a cyclical redundancy check (CRC) to the server for each file. The server recursively compares each CRC from the client with the equivalent file on the server to determine which files need to be updated or deleted. A second data transmission channel is established to transmit any updates to the client component.
