Appl. No.:

11/243068

Inventors:

Daniel Edwin Burman - Flower Mound TX, US
Kartik Subbanna - Fremont CA, US
Steven McCanne - Berkeley CA, US
David Tze-Si Wu - Fremont CA, US
Mark Stuart Day - Milton MA, US

Assignee:

International Classification:

G06F 15/173
G06F 15/16

US Classification:

709225, 709218

Abstract:

A system of network proxies distributes data to multiple servers. Each network proxy is associated with a server. A network proxy intercepts a client request for data. If the network proxy determines that the request can be served using a copy of data stored on the local server, rather than the data stored on a remote server, it diverts the request to the local server. If the network proxy determines that the request cannot be served using a data from the local server, the network proxy diverts the request to a remote server storing the primary copy of the data. A server map specifies the locations of the primary copies of data. When a primary copy of data is updated on one of the servers, the associated network proxy propagates the updated data to the other servers. The servers can provide data from files, e-mail services, databases, or multimedia services.

International Classification:

B01J 8/22
B01D 3/00

Abstract:

A process and apparatus for recycling LCO and/or HCO to a hydroprocessing zone to saturate aromatics for cracking in an FCC unit is disclosed. The recycle cracked stream may be recycled to a downstream hydroprocessing zone to avoid a first hydroprocessing zone that is primarily for demetallizing (and desulfurizing) feed to the FCC unit.
