US 2004/0165610 A1 · System and method for efficient replication and distribution of data objects

Abstract

A main execution thread retrieves a data object from a comparatively slow, mass storage device as a series of data blocks and stores each data block within an addressable element of a global counted list stored in memory. The main execution thread initiates a communication thread for each recipient device. Each communication thread is initialized with the network address of a corresponding recipient device and a list of addresses for the counted list elements containing the data blocks of the data object to be distributed. The communication threads operate independently and in parallel to retrieve the data object blocks from the global list for transmission to their respective recipient devices. Distribution status of each data block is maintained using a counter, associated with each addressable element, that is initiated to the total number of recipient devices and decremented each time the data block within the addressable element is transmitted.

Dependent claims

A method of replicating and distributing a data object from a data source to a plurality of receiving devices comprising:

(a) retrieving said data object from said data source;
(b) storing said data object as a plurality of data blocks within a storage unit, wherein each of said plurality of data blocks is stored in a corresponding individually addressable storage unit element;
(c) retrieving and transmitting to each receiving device concurrently each data block within said corresponding individually addressable storage unit elements;
and
(d) monitoring distribution of said data object to said receiving devices.

A program product apparatus including a computer readable medium with computer program logic recorded thereon for replicating and distributing a data object from a data source to a plurality of receiving devices, said program product apparatus comprising:

a distribution control module to retrieve said data object from said data source and store said data object as a plurality of data blocks within a storage unit, wherein each of said plurality of data blocks is stored in a corresponding individually addressable storage unit element;
and
a plurality of distribution modules to concurrently distribute said data blocks of said data object to each receiving device and to monitor said distribution of said data object to said receiving devices, wherein each distribution module is associated with a corresponding receiving device to retrieve and transmit to that receiving device each data block within said corresponding individually addressable storage unit elements.

A system for replicating and distributing a data object from a data source to a plurality of receiving devices comprising:

a processor to replicate and distribute said data object to said receiving devices, said processor including:
a distribution control module to retrieve said data object from said data source and store said data object as a plurality of data blocks within a storage unit, wherein each of said plurality of data blocks is stored in a corresponding individually addressable storage unit element;
and
a plurality of distribution modules to concurrently distribute said data blocks of said data object to each receiving device and to monitor said distribution of said data object to said receiving devices, wherein each distribution module is associated with a corresponding receiving device to retrieve and transmit to that receiving device each data block within said corresponding individually addressable storage unit elements.
