Patent number: 8619549Abstract: A method, apparatus and computer program product for performing location based load balancing of wireless access points and wireless switches is presented. A wireless controller (WC) receives an associate message from an Access Point (AP)/wireless switch (WS) at the WC. The WC then determines whether a preferred WC for the AP/WS is available. When the preferred WC is not available, then the WC determines if an alternate WC for the AP is available. When the alternate WC is not available, an administrator configured policy may be used that maps the AP to a specific WC. When the policy does exist then the AP is coupled to the WC according to the policy and when the policy does not exist then the WC parses the AP/WS location information for the AP/WS to determine an available geographically closest WC for the AP/WS and sends a message to the AP/WS relating to the available WC. The WC will also assign an available geographically closest WS to AP.Type: GrantFiled: May 4, 2010Date of Patent: December 31, 2013Assignee: Avaya Inc.Inventors: M S Badari Narayana, Kumara Das Karunakaran, Seemant Choudary, Veniamin Bourakov

Publication number: 20130345454Abstract: The present invention relates to a synthetic method for the preparation of phytosteryl ferulate using ferulic acid and phytosterols (isolated from soybean oil deodorizer distillate) comprising of (a) acetylation of ferulic acid to ferulic acid acetate; (b) esterification of ferulic acid acetate with phytosterols to obtain phytosteryl ferulate acetate; (c) deprotection of phytosteryl ferulate acetate to phytosteryl ferulate. The phytosteryl ferulate was evaluated for hypocholesteremic activity in hamsters in comparison with that of natural oryzanol isolated from rice bran oil soap stock. This study confirmed that the phytosteryl ferulate significantly lowers the elevated cholesterol levels and also interferes with the absorption of cholesterol and the effect is comparable with that of natural oryzanol and is useful as nutraceutical/food supplement. Hence phytosteryl ferulate is a potential substitute for natural oryzanol for several applications.Type: ApplicationFiled: February 25, 2010Publication date: December 26, 2013Applicant: COUNCIL OF SCIENTIFIC & INDUSTRIAL RESEARCHInventors: Bethala Lakshmi Anu Prabhavathi DEVI, Bhongiri YADAGIRI, Sanjit KANJILAL, Sistla RAMAKRISHNA, Kuncha MADHUSUDHANA, Prakash Vamanrao DlWAN, Rachapudi Badari Narayana PRASAD

Patent number: 8477613Abstract: A switch architecture and method provides scaling through multi-level load balancing of flows across data and application processing planes. An input/output module receives a communication session flow (forward) from a client device and selects one of a plurality of data processors to process the flow. The selected data processor determines the level of processing for the forward flow and selects an application processor from a plurality of such application processors. The application processor generates a session structure identifying actions to be performed on the forward flow and transfers the session structure to the selected data processor to perform the actions on the forward flow. The application processor also predictively generates and offloads a session structure for the associated reverse flow. If the reverse session structure is offloaded to a different data processor, either the forward or reverse flow redirects packets, or is redirected, to the data processor hosting the other flow.Type: GrantFiled: October 6, 2011Date of Patent: July 2, 2013Assignee: Rockstar Consortium US LPInventors: Kumara Das Karunakaran, M S Badari Narayana
