Abstract: A method of synchronously executing input/output operations (IOs) for a plurality of applications using a storage device with a file system includes the steps of: receiving a first write IO including an instruction to write first data at a first address of the file system; determining that, within a first range of the file system comprising the first address, there are no pending unmap IOs for deallocating storage space of the storage device from files of the plurality of applications; after determining that there are no pending unmap IOs within the first range, locking the first range to prevent incoming unmap IOs from deallocating storage space within the first range from the files of the plurality of applications; after locking the first range, writing the first data to the storage device at the first address; and after writing the first data, unlocking the first range.

Abstract: Techniques are described for vetting unwanted calls. At an inbound customer call handling apparatus, a SIP INVITE is received from a destination carrier servicing the inbound customer intended for a destination user agent (UA) device of the inbound customer. The SIP INVITE includes a current origination identifier (ORIG ID) comprised of a fixed length character string. The call handling apparatus accesses a database of stored ORIG ID character strings, each stored ORIG ID character string in the database having been included with a previous SIP INVITE that has been previously associated with an unwanted inbound call. The call handling apparatus analyzes the current ORIG ID character string to determine if it matches any stored ORIG ID character strings in the database. When there is a match to a stored ORIG ID character string, the SIP INVITE is not forwarded to the destination UA device. Otherwise, it is forwarded to the destination UA device.

Abstract: An allergen detection device that includes a sensor comprising a circuit board, an electropolymerized molecularly imprinted polymer film (MIP) that includes receptor sites imprinted in a first surface of the polymer, the receptor sites configured to accept a trace molecule of an allergen, and an electropolymerized non-imprinted polymer film. The sensor is configured to detect the presence of the trace molecule upon binding to one or more of the receptor sites on the MIP.

Abstract: An electronic flight bag for an aircraft includes a display device and a processing system. The display device is operable to render various images. The processing system is in operable communication with the display. The processing system is configured to receive various types of data from various aircraft systems and is operable, upon receipt of the data, to supply display commands to the display device that cause the display device to automatically render various images. These images may include, among other things, flight manual pages, checklists, approach charts, maintenance data, and various navigation displays. The electronic flight bag may also implement the functions of various other aircraft systems and devices.

Abstract: A BGP capable packet network device is located at the boundary of an autonomous network and in communication with a peer BGP capable packet network device in a neighboring autonomous network. The BGP capable packet network device is comprised of one or more line cards for receiving and, processing and sending packets of information, and for receiving and forwarding routing update information to a route processor comprising the packet network device. The route processor runs a border gateway protocol which is configured with one or more policies that operate to filter the routing update information received from the line card. The routing update information filter is comprised of at least one variable length path attribute and the filter operates such that it only applies the variable length path attribute one time to the routing update information.

Abstract: A packet network device includes a route processor that operates to maintain one or more forwarding tables and it includes one or more line cards that operate to process information received by the packet network device from the network and to forward the information to its correct destination. The route processor also operates to identify which incoming prefixes can be used to update the forwarding tables or to identify prefixes stored in the packet network device that can be redistributed from one network protocol to another network protocol running on the route processor. A table management function running on the route processor operates to identify the best match between an incoming prefix and information included in policy statement associated with both an ordered prefix-list and a radix tree structure.

Abstract: A distributed-forwarding router platform contains a master and a standby route processing manager (RPM). The master RPM uses dynamic internal routing codes to facilitate the replication of multicast packets within the router. As internal routing codes are assigned, the assignments are shared with the standby RPM. Should the standby RPM have to take over as the master RPM, the new master consults the internal routing codes assigned by the previous master as the new master builds multicast state, insuring that the internal routing codes the new master assigns are consistent with those used by the prior master. This allows the multicast forwarding plane to remain available during RPM failover, without a shutdown or unstable period while the new master RPM propagates internal routing codes. Other embodiments are also described and claimed.

Abstract: During initial formation of an adjacency, two neighboring PIM speakers exchange, in their hello messages, information as to whether each supports a non-stop forwarding (NSF) capability. When one of the PIM speakers restarts, the PIM neighbor senses this event, and responds by immediately forwarding its entire relevant Tree Information Base (TIB) to the restarting PIM speaker, followed by an End Of TIB (EOTIB) marker. Once the restarting PIM speaker has received TIB contents and EOTIB markers from each of its PIM neighbors, it can immediately finalize its multicast routes. In a group of routers participating in this non-stop forwarding capability, it may be possible to significantly reduce the configuration delay time currently required before purging stale multicast entries from the line card forwarding tables. Other embodiments are also described and claimed.
