Appl. No.:

13/589817

Inventors:

Hariharan Ananthakrishnan - Sunnyvale CA, US
Srinivasan Santhanam - Fremont CA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G06F 12/08

US Classification:

711118, 711E12017

Abstract:

A system operable to: receive a request for an application unit from a first device; generating a key for the application unit; look up segment cache indices corresponding to the application unit, according to the key; and determine whether the segment cache indices are available. Where the segment cache indices are available, the system may retrieve a segment cache using the segment cache indices; and then retrieve the application unit using the retrieved segment cache. Otherwise, where the segment cache indices are not available, the system may communicate the request to a second device to receive a response from the second device including the segment indices. Further, the system may receive the response from the second device; store a segment index sequence for the application unit in an application optimizer cache based on the response; and retrieve the application unit via the segment index sequence.
