Patent number: 11949658Abstract: A cloud-based traffic classification engine maintains a catalog of application-based traffic classes which have been developed based on known applications, and a local traffic classification engine maintains a subset of these classes. Network traffic intercepted by the firewall which cannot be classified by the local engine is forwarded to the cloud-based engine for classification. Upon determination of a class of the traffic, the cloud-based engine forwards the determined class and corresponding signature to the local engine. The firewall maintains a cache which is updated with the signatures corresponding to the class communicated by the cloud-based engine. Subsequent network traffic sent from the application can be determined to correspond to the application and classified according locally at the firewall based on the cached signatures. Localization of the cache to the firewall reduces latency of traffic classification operations as the catalog of classification information stored in the cloud scales.Type: GrantFiled: February 27, 2023Date of Patent: April 2, 2024Assignee: Palo Alto Networks, Inc.Inventors: Mengying Jiang, Shengming Xu, Menglan Fang, Ho Yu Lam

Publication number: 20070223644Abstract: Usually an analysis of fuel displacement accident is required before operating a reactor. In the present invention, fuel displacement accident is analyzed by linearly combining calculation results of single displacement layouts and a calculation result of a default placement layout. In this way, a number of displacement combinations to be analyzed can be reduced. And, thus, time for the analysis is saved and safety of the reactor core can be affirmed.Type: ApplicationFiled: July 21, 2006Publication date: September 27, 2007Applicant: ATOMIC ENERGY COUNCIL-INSTITUTE OF NUCLEAR ENERGY RESEARCHInventors: Weng-Sheng Kuo, Jenq-Horng Liang, Chung-Hsing Hu, Chi-Ho Fang, Wu-Hsiung Tung

Patent number: 7135426Abstract: A substrate processing chamber component demonstrates reduced erosion in an energized gas. The component has a ceramic structure composed of aluminum oxide with a surface exposed to the energized gas in the chamber. The erosion of the surface by the energized gas is substantially reduced by erosion resistant properties of the ceramic structure, which arise from a ratio of the total area of the grains GSA to the total area of the grain boundary regions GBSA in the ceramic structure of from about 0.25 to about 2.5. Also, at least about 80% of the grains in the ceramic structure have a grain size in the range of from about 1 micron to about 20 microns. The ceramic structure also has a purity of at least about 99.8% by weight to further reduce erosion of the surface.Type: GrantFiled: May 25, 2004Date of Patent: November 14, 2006Assignee: Applied Materials, Inc.Inventors: Laxman Murugesh, Stan Detmar, Ho Fang
