  • Patent number: 6748447
    Abstract: The present invention provides a system and apparatus for efficient and reliable, control and distribution of data files or portions of files, applications, or other data objects in large-scale distributed networks. A unique content-management front-end provides efficient controls for triggering distribution of digitized data content to selected groups of a large number of remote computer servers. Network distribution messages are dispatched according to a sorted list of servers, based on factors such as nearness, server processor speed, reliability, and CPU Usage. For large numbers of servers, a store-and-forward approach becomes much more efficient. A first selected server receives the message from a content control manager (CCM). The first server requests instructions for the next server listed on an ordered list in the CCM and forwards a copy of that message to the next identified server. Each server reports its completion and requests further instructions from the CCM.

  • Patent number: 6718361
    Abstract: The present invention provides a system and apparatus for efficient and reliable, control and distribution of data files or portions of files, applications, or other data objects in large-scale distributed networks. A unique content-management front-end provides efficient controls for triggering distribution of digitized data content to selected groups of a large number of remote computer servers. Transport-layer protocols interact with distribution controllers to automatically determine an optimized tree-like distribution sequence to group leaders selected by network devices at each remote site. Reliable store-and-forward transfer to clusters is accomplished using a unicast protocol in the ordered tree sequence. Once command messages and content arrive at all participating group leaders, local hybrid multicast protocols efficiently and reliably distribute them to the back-end nodes for interpretation and execution.
