Abstract: When a node has to restart its control component, or a (e.g., label-switched path signaling) part of its control component, if that node can preserve its forwarding information across the restart, the effects of such restarts on label switched path(s) include the restarting node are minimized. A node's ability to preserve forwarding information across a control component (part) restart is advertised. In the event of a restart, stale forwarding information can be used for a limited time before. The restarting node can use its forwarding information, as well as received label-path advertisements, to determine which of its labels should be associated with the path, for advertisement to its peers.

Abstract: Techniques for assessing a resiliency level in an information technology system and architecting the information technology system in accordance with the resiliency level are disclosed. An estimated resiliency level may be estimated from different system characteristics to obtain an estimated resiliency level for the information technology system. The cost and the degree of effort to design for the information technology system may be estimated from the estimated resiliency level. The resiliency level may be further determined from different system factors. Consequently, a specification for a resiliency feature is obtained by accessing a set of resiliency guidelines based on the resiliency level and a technology theme. The resiliency feature may then be applied to the information technology system.

Abstract: Configuration requirements for an Availability Management Framework (AMF) configuration are generated from high level user requirements that specify a subset of properties of an AMF configuration. The user requirements are first mapped into entity prototypes defined in an extended Entity Types File (ETF) model. A computer system identifies additional entity prototypes and dependency thereof that support functionalities of the mapped entity prototypes under a set of grouping conditions. The computer system calculates the required number of component service instances (CSIs) and service instances (SIs) that satisfy the user requirements. The calculation is based on the subset of the properties specified by the user requirements and measurements associated with the entity prototypes in the extended ETF model. The computer system then forms configuration requirements including the required number of CSIs and SIs for generating the AMF configuration that satisfies the user requirements.

Abstract: The storage system of the present invention is able to generate one virtual logical device from different logical devices which exist in each of the different storage control units and remote-copy all or part of the virtual logical device to another logical device. The same virtual identifier is set for a volume of the first storage unit and for a volume of the second storage unit. The path control unit of the host identifies a plurality of volumes which have the same virtual identifier as one virtual volume. A remote copy pair can also be set by a virtual volume and a volume of the third storage unit. The setting of the virtual volume and the setting of the remote copy can be performed by means of an instruction from the management server.

Abstract: A client-side enforcement mechanism may allow application security policies to be specified at a server in a programmatic manner. Servers may specify security policies as JavaScript functions included in a page returned by the server and run before other scripts. At runtime, and during initial loading, the functions are invoked by the client on each page modification to ensure the page conforms to the security policy. As such, before a mutation takes effect, the policy may transform that mutation and the code and data of the page. Replicated code execution may take place at both the client and the server where the server runs its own shadow copy of a client-side application in a trusted execution environment so that the server may check that the method calls coming from the client correspond to a correct execution of the client-side application The redundant execution at the client can be untrusted, but serves to improve the responsiveness and performance of the Web application.

Abstract: A computing core includes a processing module, main memory, and a memory controller. The memory controller receives a request to fetch an instruction from the processing module and determines whether the instruction is currently stored in the main memory. When the instruction is not currently stored in the main memory, the memory controller determines whether the instruction is stored in a distributed storage network (DSN) memory as one or more sets of encoded instruction slices; and, when it is, the memory controller addresses the DSN memory to retrieve the one or more sets of encoded instruction slices. When at least a threshold number of encoded instruction slices are retrieved for each of the one or more sets of encoded instruction slices, the one or more sets of encoded instruction slices are decoded using a dispersed storage error coding function to reconstruct the instruction, which is provided to the processing module.

In the event it is determined to adjust the set of receiver parameters, a new set of values is generated for the set of receiver parameters using a cost function (where the cost function does not assume a noise signal in a receive signal to have a particular statistical distribution) and the set of receiver parameters is changed to have the new set of values.

Abstract: An apparatus and method improves the fault tolerance of a rocket or missile guidance system which includes a resonant sensor. When improper initialization is detected, the resonant sensor is reinitialized, repeatedly if necessary, until normal operation is achieved. Improper initialization is detected by comparing data from the guidance system with pre-specified physical limits to roll, pitch, yaw, and/or other features of the flight scenario. Embodiments can also detect a fault condition due to an error signal from a “Built-in-Test” (BIT) module. The initialization sequence initiated by the invention can be identical to the power-on sequence, or it can be a separate, reinitiating sequence. Subsequent resets are initiated as needed, for example until the burn of the rocket fuel and the associated vibrations have ceased and the resonant sensor has been successfully initialized.

Abstract: The method determines whether a particular node of a high availability cluster is functioning properly or is a failed node. The method dumps node process state information as a dump data for the failed or crashed node in a shared storage area of the high availability cluster. A high availability cluster manager identifies the dump data that corresponds to the failed node as the most recent dump data for that failed node. The high availability cluster manager interrogates the dump data using kernel debugger services to identify a process trace and thereby identify the crash-causing application for the failed node. The method determines if the dump data includes a process match for the failed node process. The high availability cluster manager may initiate a crash-causing application notification to administrators or other entities of the high availability cluster.

Abstract: A method, system, machine-readable storage medium, and apparatus are directed towards upgrading a cluster by bifurcating the cluster into two virtual clusters, an “old” virtual cluster (old active cluster) and a “new” virtual cluster (new standby cluster), and iteratively upgrading members of the old cluster while moving them into the new cluster. While members are added to the new cluster, existing connections and new connections are seamlessly processed by the old cluster.

Once a threshold number of members have been transferred to the new cluster, control and processing may be taken over by the new cluster. Transfer of control from the old cluster to the new cluster may be performed by failing over connectivity from the old cluster to the new cluster.
