International Classification:

G06F 12/08

US Classification:

711137, 726 12

Abstract:

The invention provides a storage and retrieval routine for Web objects. A Web page typically includes several objects such as text, images and hyper-links to other Web pages. Each Web page and its objects are usually stored in separate files. A storage and retrieval routine stores objects that correspond to the same Web page in co-located positions on a disk. Therefore, when the Web page and its embedded and hyper-linked Web objects are retrieved, the seek time is reduced, thereby reducing the object retrieval time as perceived by a computer user and increasing the number of requests per second that a Web content server can deliver.

US Classification:

709233

Abstract:

A computer readable medium comprising computer readable code for data transfer. The computer readable code, when executed, performs a method. The method includes receiving, at a first Axon, an ARP request from a source host directed to a target host. The method also includes obtaining a first route from the first Axon to the second Axon, and generating a target identification corresponding to the target host. The method further includes sending an Axon-ARP request to the second Axon using the first route, and receiving an Axon-ARP reply from the second Axon, where the Axon-ARP reply includes a second route. The method further includes storing the first route in storage space on the first Axon, where the storage space is indexed by the target identification, and sending an ARP reply to the first host where the source host is configured to send a packet to the target host.
