20100011245 | FAULT TOLERANT ROUTING IN A NON-HOT-STANDBY CONFIGURATION OF A NETWORK ROUTING SYSTEM - Methods and systems for facilitating fault tolerance in a non-hot-standby configuration of a network routing system are provided. According to one embodiment, a method is provided for replacing an active processing engine with a non-hot-standby processing engine. Multiple processing engines within a network routing system are configured. The processing engines include an active processing engine having one or more software contexts, representative of a set of objects implementing a virtual router, for example, and a non-hot-standby processing engine having no pre-created software contexts corresponding to the one or more software contexts. Responsive to determining a fault associated with the active processing engine, the active processing engine is dynamically replaced with the non-hot-standby processing engine by creating replacement software contexts within the non-hot-standby processing engine corresponding to the one or more software contexts. | 01-14-2010 |
20100281296 | FAULT TOLERANT ROUTING IN A NON-HOT-STANDBY CONFIGURATION OF A NETWORK ROUTING SYSTEM - Methods and systems for facilitating fault tolerance in a non-hot-standby configuration of a network routing system are provided. According to one embodiment, a failover method is provided. A fault manager executing on a control blade of multiple server blades of a network routing system actively monitors an active processing engine of multiple processing engines within the network routing system. Responsive to detecting a fault associated with the active processing engine, the active processing engine is dynamically replaced with a non-hot-standby processing engine of the multiple processing engines by (i) determining one or more software contexts that were associated with the active processing engine prior to detection of the fault, and (ii) creating one or more replacement software contexts within the non-hot-standby processing engine corresponding to the one or more software contexts. | 11-04-2010 |
20110185221 | FAULT TOLERANT ROUTING IN A NON-HOT-STANDBY CONFIGURATION OF A NETWORK ROUTING SYSTEM - Methods and systems for facilitating fault tolerance in a non-hot-standby configuration of a network routing system are provided. According to one embodiment, a failover method is provided. One or more processing engines of a network routing system are configured to function as active processing engines, each of which having one or more software contexts. A control blade is configured to monitor the active processing engines. One or more of the processing engines are identified to function as non-hot-standby processing engines, each of which having no pre-created software contexts corresponding to the software contexts of the active processing engines. The control blade monitors the active processing engines. Responsive to detecting a fault associated with an active processing engine the active processing engine is dynamically replaced with a non-hot-standby processing engine by creating one or more replacement software contexts within the non-hot-standby processing engine corresponding to those of the active processing engine. | 07-28-2011 |
20130227340 | FAULT TOLERANT ROUTING IN A NON-HOT-STANDBY CONFIGURATION OF A NETWORK ROUTING SYSTEM - Methods and systems for facilitating fault tolerance in a non-hot-standby configuration of a network muting system are provided. According to one embodiment, a failover method is provided. One or more processing engines of a network routing system are configured to function as active processing engines, each of which having one or more software contexts. A control blade is contoured to monitor the active processing engines. One or more of the processing engines are identified to function as non-hot-standby processing engines, each of which having no pre-created software contexts corresponding, to the software contexts of the active processing engines. The control blade monitors the active processing engines. Responsive to detecting a fault associated with an active processing engine the active processing engine is dynamically replaced with a non-hot-standby processing engine by creating one or more replacement software contexts within the non-hot-standby processing engine corresponding to those of the active processing engine. | 08-29-2013 |

20080222653 | METHOD AND SYSTEM FOR TIME-SLICED AGGREGATION OF DATA - Systems and methods are disclosed herein for aggregating event data in order to reduce the amount of storage space necessary to store event data for later use in statistical analyses of the event data. The raw event data is analyzed and, for each event ID within a time period, a specific set of numbers and sums are calculated. This set is then stored instead of the raw event ID and used for all subsequent analyses of the events. The set of numbers and sums reduce the amount of storage required for each event ID within a time period to a set of five data elements, regardless of the number of underlying events in the raw event data. The set of number and sums include a number of events, a sum of the events, a sum of the squares of the events, a sum of the cubes of the events and a sum of the events raised to the fourth power. | 09-11-2008 |
20090204319 | REAL TIME PARKING SEARCH AND POINT-TO-POINT DIRECTION GENERATOR - Methods, systems, and apparatuses for mapping parking locations and for selecting parking are described. A search for parking resources proximate to a destination geographic location is performed. Parking information is generated based on the results of the search. The parking information may be displayed on a map of the destination geographical location. A map of the destination geographical location may be displayed with the parking information. A user may be enabled to select a parking location indicated on the map. The user may reserve the selected parking location if the selected parking location is determined to be reservable. Travel directions (e.g., for walking) from the selected parking location to the destination geographic location may be generated, and may be indicated on the map. | 08-13-2009 |
20100007525 | REAL TIME DETECTION OF PARKING SPACE AVAILABILITY - Methods, systems, and apparatuses for determining parking availability are described. A sensor system is configured to monitor a plurality of parking spaces. The sensor system includes at least one sensor element that generates a sensor data output signal. A parking availability determiner receives the sensor data output signal and generates parking availability information. The parking availability determiner is configured to determine from the received sensor data output signal at least one parking space of the plurality of parking spaces that is occupied, and to include an indication in the parking availability information that the determined at least one parking space is occupied. If one or more further parking space are included in the plurality of parking spaces other than the determined at least one parking space, an indication is included in the parking availability information that the further parking spaces are available for parking. | 01-14-2010 |
