UPGRADING A PHYSICAL SECURITY SYSTEM HAVING MULTIPLE SERVER NODES

摘要

A physical security system that includes multiple server nodes may be upgraded by receiving an upgrade installation package from a client and propagating the installation package between at least two of the server nodes. One of the server nodes (“source server”) receives the installation package from the client and another of the server nodes (“requesting server”) requests and receives the installation package from the source server. To transfer the installation package from the source to the requesting server, the source server notifies the requesting server that the installation package is present at the source server, the requesting server then sends the source server a request for the installation package, and the source server then sends the installation package to the requesting server in response to the request. The requesting server may then be upgraded by running the installation package.
