Inventors:

Kevin T. Lewis - Boston MA
David L. Hoey - Wayland MA

Assignee:

InfoLibria, Inc. - Waltham MA

International Classification:

G06F 1730

US Classification:

707 10, 707 1, 707 2

Abstract:

A technique for optimizing delivery of specialized content files such as multimedia files in a computer network. A multimedia file cache is located at a point of presence, such as at an Internet Service Provider (ISP), gateway, or other place close to user connection points into the network. A redirection function intercepts media redirection file requests sent to or from the media server and rewrites such requests so that they point to the local media file cache.

International Classification:

G06F 1516

US Classification:

709202, 709105, 709238, 370401

Abstract:

A technique fulfills service requests in a system of computers that communicate as nodes within a network. The technique involves sending, in response to an initial service request that requests a service provided by a primary server node, a mobile agent from the primary server node to an intermediate node. The mobile agent indicates to the intermediate node that a secondary server node is capable of providing the service. The technique further involves intercepting, at the intermediate node, a subsequent service request sent from a client node to the primary server node, the subsequent service request requesting the service, and sending an instruction from the intermediate node to the secondary server node. The instruction instructs the secondary server node to provide the service. The technique further includes providing, in response to the instruction, the service from the secondary server node to the client node.
