The invention is directed to monitoring execution of software threads, particularly by detecting a lockup or stall in execution of a software thread and initiating a remedial action in response. Advantageously, some embodiments of the invention automatically detect a lockup or stall in execution of a software thread by periodically sampling information corresponding to the thread, and, in accordance with a determination made using the information, initiate an attempt to recover from such a condition in execution without the need for manual intervention.

Various exemplary embodiments relate to a method and related node for outputting packets from a playout buffer in a node in a packet-switched network including one or more of the following: configuring a Time-Division Multiplexing (TDM) pseudowire terminating at the node; receiving a plurality of fixed-length packets transmitted over the TDM pseudowire; adding the plurality of fixed-length packets to the playout buffer such that the playout buffer reaches a current fill level; inserting at least one dummy packet into the playout buffer, wherein a total length of the at least one dummy packet is equal to a target fill level of the playout buffer minus the current fill level and the target fill level represents a minimum fill level required before output of packets from the playout buffer; and outputting the plurality of fixed-length packets and the at least one dummy packet from the playout buffer.

Various exemplary embodiments relate to a method and related network node including one or more of the following: maintaining a line card activity number at each line card in the node; receiving a first packet belonging to a flow; storing, at each line card, a flow record in a line card context identifier storage, wherein the flow record contains a flow activity number being initially set equal to a current value of the line card activity number; detecting, by the second line card, a change in designation to active and changing the value of the line card activity number maintained by the second line card; receiving a second packet belonging to the flow; and transmitting, to the decompressor node, an update packet including the flow context identifier and the flow identifying information, upon determining that the flow activity number is not equal to the updated line card activity number.

A method for identifying faulty modules within telecommunication devices, such as ATM switches, involves generating and attaching verification codes, such as CRC or checksum codes, to data packets, such as ATM cells, at an upstream location, determining the integrity of the verification codes at each of multiple downstream location within a telecommunication device; and signaling an error condition where a corrupted data packet has been detected. A verification code may be written to a filed of a data packet which is not used while the ATM cell is in transit through the telecommunication device, thereby identifying a faulty module device without adversely affecting throughput.

A method and system for responding to a trigger condition detected during the handling of a call connection in an intelligent network (IN). Upon receipt of an IN trigger, a service interaction manager in a service control point queries a home location register for a subscriber involved in the call connection requesting subscriber subscription information. The service interaction manager also queries a service library associated with the service control point to determine which of an implicated set of services are currently available in the service library and what the properties of those services are. Depending upon which services are available, which services are in the subscriber's subscription list, and the service priority information received from the home location register and the service library, including the properties data from the service library, the service interaction manager reduces the list of implicated services to an applicable set of services and generates a customized execution sequence for the applicable services. Thereafter, at least one of the applicable services is executed in accordance with the customized execution sequence.

Various exemplary embodiments relate to a method and related network node having a playout buffer including one or more of the following: receiving, at the network device, a first packet belonging to a first flow, the first packet including a first sequence number (SN); receiving, at the network device, a second packet belonging to the first flow, the second packet including a second SN; determining that the second SN is not in sequence with the first SN; waiting to receive, at the network device, a third packet belonging to the first flow, the third packet including a third SN; and determining that a jump in SNs has occurred for the first flow between the first packet and the second packet based on determining that the third SN is in sequence with the second SN.

Various exemplary embodiments relate to a method and related network node having a playout buffer including one or more of the following: receiving a first packet, a second packet, a first set of at least one subsequent packet, wherein each packet includes a sequence number (SN); determining that the second packet is not in sequence with the first packet by determining that the SN of the second packet is not equal to the SN of the first packet plus an expected increment value; determining whether the second packet represents a jump in SNs by determining whether the SN of a first subsequent packet is equal to the SN of the second packet plus the expected increment value; and when the second packet represents a jump in SNs, gradually normalizing the playout buffer upon receipt of each subsequent packet.
摘要:
The present invention provides method and system for identifying a faulty component in a group of components, the group comprising in a connected configuration at least a first component connected to a second component, and further connected to at least a third component. In an embodiment, the method comprises: (i) monitoring for at least one fault at a component connection interface; and (ii) upon detection of a fault, identifying the faulty component utilising information from the fault and at least one rule for identifying the faulty component. The rules are defined from at least one characteristic of the fault, such as location and frequency, and at least one characteristic of the configuration.
摘要:
Techniques and apparatus for aggregating social network service (SNS) data are disclosed. In an example method for operating a computerized SNS aggregator having a plurality of account holders, identifiers for one or more external network-accessible SNS accounts associated with each of several account holders are collected and stored. An access token for each of the associated external network-accessible SNS accounts is collected and stored. Data-sharing relationships between pairs of account holders having linked accounts within the SNS aggregator service are identified. Subsequently, one or more account holders having a data-sharing relationship with a first account holder are identified. One or more external network-accessible SNS accounts for each of the other account holders are accessed, using the corresponding stored access tokens. Finally, a data feed for the first account holder is assembled, using data items retrieved from the external network-accessible SNS accounts for the other account holders.
