Jun 6, 2007
Appl. No.:
11/758990
Inventors:
Santanu Sinha - Cupertino CA, US
Shahriar I. Rahman - Morgan Hill CA, US
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
H04L 12/28
US Classification:
370392, 370389
Abstract:
Embodiments of the present invention include a method, an apparatus, and logic encoded in one or more computer-readable tangible medium to carry out a method. One method includes tagging packets and forwarding packets in a wireless mesh network using stored forwarding information for the tag, wherein the forwarding information is according to a centrally determined routing method and tag distribution method.

Flexible Access Control Policy Enforcement

US Patent:
7945941, May 17, 2011
Filed:
Jun 1, 2007
Appl. No.:
11/757215
Inventors:
Santanu Sinha - Cupertino CA, US
David J. Pignatelli - Saratoga CA, US
Alan Carr - San Jose CA, US
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
G06F 21/20
G06F 15/16
H04L 29/06
US Classification:
726 1, 726 14, 709228
Abstract:
A method and system for applying access-control policies. In particular implementations, a method includes determining one or more policies, and a prioritization order for the determined policies, based on the one or more parameters; accessing an indirection table to create an entry for the client, wherein the entry indicates the prioritization order of the determined policies; and creating one or more entries in one or more policy data structures for the one or more determined policies.

Dual Cryptographic Keying

US Patent:
8131994, Mar 6, 2012
Filed:
Jun 1, 2007
Appl. No.:
11/756783
Inventors:
Santanu Sinha - Cupertino CA, US
Kenneth William Batcher - Hudson OH, US
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
H04L 29/00
US Classification:
713151, 713150, 713152, 713158, 713160, 713168, 726 2, 726 13, 726 14, 380274, 380249, 380270, 380277, 709227, 709228, 709229
Abstract:
A dual cryptographic keying system. In particular implementations, a method includes responsive to an initial session key negotiation, storing security association information for a tunnel in a security association memory; responsive to a session key renegotiation, storing security association information for the tunnel in a cache; decrypting received packets associated with the tunnel conditionally using the security association information in the cache or the security association information in the security association memory; and upon an expiration condition, overwriting the security association information, for the tunnel, in the security association memory with the security association information, for the tunnel, copied from the cache.

Priority-Aware Hierarchical Communication Traffic Scheduling

US Patent:
8339949, Dec 25, 2012
Filed:
Oct 24, 2007
Appl. No.:
11/976459
Inventors:
Santanu Sinha - Cupertino CA, US
Assignee:
Cortina Systems Inc. - Sunnyvale CA
International Classification:
H04L 12/28
US Classification:
3702301, 3703954, 370230
Abstract:
Priority-aware hierarchical communication traffic scheduling methods and apparatus are disclosed. Communication traffic is scheduled by schedulers. Each scheduler supports a multiple priority scheduling function to schedule communication traffic having any of multiple priorities. The communication traffic scheduled by the schedulers is further scheduled based on the priorities of the communication traffic scheduled by each of the schedulers. Traffic shaping may also be integrated into a hierarchical scheduler. The priority-aware further scheduling and the optional shaping may be implemented, for example, using multiple Active lists, one per traffic priority, and a Pending list to which a scheduler can be added if it has communication traffic to schedule but is not allowed to schedule that traffic due to the shaping.

8522007, Aug 27, 2013
Filed:
Mar 6, 2012
Appl. No.:
13/413359
Inventors:

Policy-Based Tunneling Of Multicast Streams

US Patent:
2008018, Aug 7, 2008
Filed:
Feb 1, 2007
Appl. No.:
11/670294
Inventors:
Santanu Sinha - Cupertino CA, US
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
H04L 12/56
US Classification:
370389
Abstract:
A policy-based multicast tunneling system. In particular implementations, a method includes maintaining a plurality of multicast tunnels with one or more remote network elements, each multicast tunnel being operable to carry one or more multicast streams; forwarding one or more packets of a multicast stream using selected multicast tunnels of the plurality of multicast tunnels; and applying one or more policies operative to control subscriptions to one or more of the plurality of multicast tunnels.

Dynamic Power Management In A Communications Device

US Patent:
2012019, Jul 26, 2012
Filed:
Sep 19, 2011
Appl. No.:
13/235927
Inventors:
Mehmet V. TAZEBAY - Irvine CA, US
Bruce Conway - Aliso Vejo CA, US
Santanu Sinha - Cupertino CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
G06F 1/32
US Classification:
713323
Abstract:
A method and system to dynamically manager power in a communication system are provided herein. The method comprises the steps of monitoring a transmit data queue once every first pre-determined period of time and determining whether the transmit data queue is empty for a pre-determined number of times. The method further includes the step of generating a transition state signal to stop de-queuing of data from the transmit queue if the transmit data queue is empty for the pre-determined number of times and selectively operating portions of a Physical Layer (PHY) that are used for functions other than transmitting and receiving an idle signal in a low power mode.
