US Patent:

7400578, Jul 15, 2008

Filed:

Dec 16, 2004

Appl. No.:

11/014066

Inventors:

Robert Earl Guthrie - Austin TX, US
Jeffrey Mark Achtermann - Austin TX, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04J 1/16
H04J 3/14

US Classification:

370229, 370232

Abstract:

A method is presented for throttling data transmissions within a data processing system. Information about a data transfer from a server to a client is received within the application layer of a server, which stores the information about the data transfer along with information about a number of recent data transfers from the server to the client to create a sliding window of historical information about data transfers. The data transfer from the application layer of the server is delayed within the application layer of the server for an amount of time that is approximately equal to a computed delay time value in response to a determination that an average data transfer rate over the number of recent data transfers from the server to the client may exceed a data transfer rate threshold parameter.

Assignee:

International Classification:

G06F 15/16

US Classification:

709232, 709231

Abstract:

Systems and methods for the distribution of bulk data using multicast routing are provided. A multicast advertisement is sent to potential receivers of the bulk distribution. The advertisement may include a list of intended receivers and the ‘multicast group that the distribution will be multicast on. In response to the advertisement, intended receivers may listen on the multicast group address for the bulk data. Receivers that are not targets for the distribution do not join the multicast group, and consequently, the delivery of data by routers to subnets that have no target receivers may thus be obviated.
