Abstract: A method is disclosed for determining a location of a client session in a telecommunications network by comparing attributes of the client session connection to location definition information stored in a configuration file. A method of handling requests from proxy and non-proxy client connections in a telecommunications network by redirecting requests from unauthenticated proxy clients to a transparent proxy port on a captive portal such that the captive portal proxies the requests is also disclosed. The request may be directed to a service, such as a destination IP address and optional port number. A method for a proxy server to identify an edge session through an out-of-band request containing proxy metadata to a web portal for secure (HTTPS) requests is also disclosed. The edge session is identified for the web portal through a hostkey determined by the proxy server.

Abstract: Techniques are provided for efficiently processing SOAP requests at a Web service application (WSA) of a multi-functional device (MFP). In one technique, a WSA includes at least three threads. An external request processing thread processes SOAP requests from different client applications. A request processing thread processes a SOAP request according to the business logic of the WSA. A internal communications thread communicates with other components of the MFP that are distinct from the WSA. In another technique, a WSA processes different SOAP request differently, depending on the size of the SOAP and the resources required to process the SOAP request so that fast requests may be processed immediately while slow requests are pending. In another technique, a WS-Eventing specification is implemented within a WSA to simplify the event subscription and notification process.

Abstract: Techniques are provided for searching within a collection of XML documents. A relational table stores an entry for each node of a set of nodes in a collection of XML documents. Each entry of the relational table stores an order key and a path identifier along with the atomized value of the node. Instead of storing the atomized value in a full-text index, a virtual column can be created to represent, for each node, the atomized value of the node. Alternately, each entry of the relational table stores an order key and a path identifier along with, for simple nodes, the atomized value, and for complex nodes, a null value. For a complex node with a descendant text node, a separate entry is stored for the descendant text node in the relational table.

Abstract: According to one embodiment of the invention, an approach is provided for determining alternative printing device arrangements. In general, the geographic locations, usage and costs of an existing set of printing devices are analyzed. A determination is made, based upon this analysis, whether one or more of the existing printing devices can be replaced by one or more replacement printing devices to provide an alternative printing device arrangement that has lower costs. The lower costs may reflect lower operational costs, lower energy costs, lower acquisition costs, or any combination of lower operational costs, lower energy costs and lower acquisition costs.

Abstract: An approach for managing the consumption of resources uses adaptive random sampling to decrease the collection of flow statistical data as the consumption of resources increases. When a packet is received from a network, a determination is made whether the packet belongs to an existing flow, for which flow statistical data is being collected, or to a new flow. If the packet belongs to an existing flow, then the flow statistical data for the existing flow is updated to reflect the packet. If the packet belongs to the new flow, then a sampling probability is used to determine whether the new flow is to be sampled. The sampling probability is determined, at least in part, upon a current usage of resources.

Abstract: Techniques are described herein for expanding the range of data targeted in I/O requests made by clients, so that the expanded range results in aligned I/O operations within the file system. Data that is included in the expanded range, but was not actually requested by the client, is trimmed off the data chunk returned by the file system, so that the client receives only the data required by the client. The blocks that contain the partially-read data are cached, so that they can be provided to the clients in response to subsequent I/O requests, without having to retrieve the blocks again from the file system. The I/O requests of multiple clients are handled by a read scheduler that uses a single global queue for all such requests. When appropriate, the read scheduler creates companionship relationships between the requests, and services the “companion” requests based on the data returned for the requests with which the companion requests are associated.

Abstract: A method is disclosed for cryptographic peer discovery, authentication, and authorization. According to one embodiment, a data packet, which is addressed to a destination device other than an intermediary network device, is intercepted at the intermediary network device. The data packet contains a request and a group identifier. A shared secret cryptographic key, which is mapped to the group identifier, is selected. A challenge is sent toward an upstream device from whence the data packet came. A response is received. A verification value is generated based on the cryptographic key and the challenge. It is determined whether the response matches the verification value. If the response matches the verification value, then it is determined whether the request is allowed by an authorization set that is mapped to the group identifier. If the request is allowed, then a policy of the intermediary network device is configured based on the request.

Abstract: Database server instances in a database server cluster broadcast, to other instances in the cluster, information concerning certain problem events. Because each server instance is aware of problems that other server instances are experiencing, each server instance is enabled to make more intelligent decisions regarding the actions that it should perform in response to the problems that the server instance is experiencing. Instead of terminating itself, a server instance might opt to wait for a longer amount of time for an operation to complete. The server instance may do so due to the server instance having received information that indicates that other server instances are experiencing similar problems. Whenever the information received from other server instances makes it appear that a problem is unlikely to be solved in the cluster as a whole by terminating a server instance, that server instance may continue to wait instead of terminating itself.

Abstract: A system and method are disclosed for providing interaction with mail data on a server. Providing interaction with mail data on a server comprises receiving mail information from the server; updating data structures in a client using the mail information received; operating on the mail information at the client and displaying operation results on the client; sending operation information to the server so that the same operation may be executed on the server.

Abstract: Storing audio data encoded in any of a plurality of different audio encoding formats is enabled by parametrically defining the underlying format in which the audio data is encoded, in audio format and packet table chunks. A flag can be used to manage storage of the size of the audio data portion of the file, such that premature termination of an audio recording session does not result in an unreadable corrupted file. This capability can be enabled by initially setting the flag to a value that does not correspond to a valid audio data size and that indicates that the last chunk in the file contains the audio data. State information for the audio data, to effectively denote a version of the file, and a dependency indicator for dependent metadata, may be maintained, where the dependency indicator indicates the state of the audio data on which the metadata is dependent.

Abstract: An approach is provided for implementing locked printing on a printing device with unlock via a keypad attached to the printing device via an interface. A user may specify for printing print jobs stored at a printing device using a keypad device to enter a job ID associated with a particular print job or a general ID associated with users to release all print jobs associated with a particular user, all print jobs not yet printed, or all print jobs. Print jobs may alternatively be identified by date. The approach may also include a user viewing a list of available locked print jobs on a user interface of the printing device, along with the associated job IDs. The approach may further include the use of a Web server on the printing device to generate and provide a Web page that lists stored print jobs and their associated job IDs.

Abstract: Imaging apparatus includes a mosaic image sensor (24), which is configured to generate a stream of input pixel values belonging to a plurality of input sub-images, each sub-image responsive to light of a different, respective color that is incident on the mosaic image sensor. An image restoration circuit (26) is coupled to receive and digitally filter the input pixel values in each of the input sub-images so as to generate a corresponding plurality of enhanced output sub-images. An image signal processor (ISP) (28) is coupled to receive and combine the plurality of the output sub-images in order to generate a color video output image.

Abstract: An approach is provided for securely printing policy-enabled electronic documents. According to the approach, a determination is made at a client device whether policy-enabled printing has been specified for a particular electronic document. If policy-enabled printing has been specified for the particular electronic document, then a determination is made whether a print driver, installed on the client device for supporting printing for a particular printing device, is configured to support policy-enabled printing. Also, a determination is made whether the particular printing device is currently configured to support policy-enabled printing. The particular electronic document is allowed to be processed at the client device for printing only if both the print driver is configured to support policy-enabled printing and the particular printing device is currently configured to support policy-enabled printing.

Abstract: A search results page contains images that are organized based on the visual features of those images; images that have common visual features are grouped together using either a folding or a reciprocal election technique. Images that pertain to a particular meaning of a query term are less likely to be scattered across the page. A group of images that have common visual features is represented on the page by a single representative image from that group. Consequently, space for more representative images becomes available on the image search results page. Thus, search results page contains visually diverse representative images; space on the results page is not wasted by repeatedly showing the same image. The initial image search results page also therefore is more likely to contain representative images that otherwise would have occurred too far down a relevance-ranked list to be included within the initial search results page.

Abstract: A technique is provided for providing an aggregate tag view of a website that comprises a plurality of webpages that each has a corresponding URL. A tag is a set of one or more words that have been associated with a URL and is typically created by a user to describe content of the webpage corresponding to the URL. Initially, a request is received to display information pertaining to a website. In response to the request, a plurality of tags associated with the website is displayed. A first subset of the plurality of tags is associated with a particular URL. A second subset of the plurality of tags is associated with one or more URLs that are not the particular URL. Alternatively, or in addition to an aggregate tag view tag-related information for each URL of the website is provided, in response to the initial request.

Abstract: A multimedia visual progress indication system that provides a cache bar that is overlaid onto the program material or displayed on a dedicated display. A cache bar indicates the length of a recording session or the length of stored program material and expands to the right when material is being recorded. Index and/or bookmark indicators are displayed next to the cache bar. A position indicator moves within the cache bar and tells the user visually where his current position is within the program material. Numeric time or counter mark of the current position is displayed in the vicinity of the cache bar. The trick play bar and its associated components are displayed for a predetermined time period.

Abstract: An apparatus and method are described for discovering a configured tunnel between nodes on a path in a data communications network. In an embodiment, an apparatus is arranged to remotely access at least one node on the path, identify whether a tunnel is configured on the access node and, if so, identify whether the identified tunnel has a fault.

Abstract: Example systems and methods associated with router synchronization are described. One example method includes reducing a likelihood that a first network device will be favored over a peer device as a router. This likelihood may be increased after the first network device has received a threshold amount of routing information from the peer device. This may allow the first network device to begin performing non-routing related tasks after it starts up without causing interruption of data streams for which the first network device does not have current routing information.

Abstract: Techniques are provided for desktop streaming over wide area networks. In one embodiment, a computing device comprises logic that is configured to intercept file open requests for files stored in a file system, where at least some of the files in the file system may have not yet been fully downloaded. In response to a request to open a file, the logic is configured to modify a first sharing mode specified therein and to open the file in a read-write sharing mode that allows other processes to open the file. While one or more blocks of the file are being downloaded or written into the file, the logic is configured to check whether a second sharing mode received in a subsequent request to open the file is compatible with the first sharing mode. If the second sharing mode is not compatible with the first sharing mode, the logic is configured to deny the subsequent request even though in the file system the file is opened in the read-write sharing mode.
