  • Patent number: 9870303
    Abstract: A dynamic monitoring process begins with configuring a start and end method to be monitored. The dynamic monitoring process may intercept both the start and end methods as and when the loader is initiated or at runtime to dynamically attach and detach the instrumentation. A loader may then be modified to call a library method upon detection of the start method. The library method may serve as a notification to the start of the method and causes a reflector to retrieve information from the incoming request. The incoming information may include data from which a business transaction name may be determined. The business transaction name is then associated with the monitoring of the particular request. When an exit call is detected, a call may be made to the library for a method which invokes a decorator. The decorator may insert business transaction name and other data into the outgoing call.

  • Patent number: 9869643
    Abstract: Masks that selectively attenuate radiation for inspections of printed circuit boards (PCB) are disclosed. A PCB may be inspected for defects by exposing the PCB with radiation and analyzing the radiation transmitted through the PCB. By employing a radiation mask having first and second segments between the PCB and a radiation source, the radiation may be selectively attenuated to attenuate a first portion of the radiation with a first attenuation level to prevent performance degradation to sensitive semiconductor devices as part of a first sectional area of the PCB, and yet provide substantially non-attenuation or attenuation at a second attenuation level for a second portion of the radiation incident upon a second sectional area of the PCB which is free from sensitive semiconductor devices. In this manner, the selective attenuation enables inspection of the first and second sectional areas of the PCB without damage to the sensitive semiconductor devices.

  • Patent number: 9870219
    Abstract: Mechanisms for switch upgrades using remote containers. An example system can export, to a server, a state of software processes associated with a first software container at the system. The system can generate a lightweight software container configured to forward traffic associated with the first software container to a second software container at the server, generated based on the state. The system can perform a switchover between the first software container and lightweight software container. The switchover can enable the lightweight software container to forward, to the second container, traffic associated with the first software container. The system can generate a fourth software container based on a snapshot of the second software container, and perform another switchover between the lightweight software container and fourth software container.

  • Patent number: 9871864
    Abstract: Techniques are provided for the creation of a peer zone definition for use in a Fibre Channel (FC) Fabric. The peer zone definition defines a peer zone in which two or more initiator host devices are each permitted to communicate with a target device, but the two or more initiator host devices are prevented from communicating with each other. In accordance with one example, a target device and of two or more initiator host devices connected to the FC Fabric are received. A peer zone definition is created, and the peer zone definition is transmitted to the switches composing the FC Fabric for enforcement.

  • Patent number: 9871653
    Abstract: A technique for key sharing among multiple key servers connected to one another over a communication network is provided herein. Each key sever of the multiple key servers stores respective cryptographic keys, and provides the keys to a local device group connected with the key server, to enable the device group to encrypt messages with the keys. Each key server acts as a proxy for the other key servers in order to receive other keys from the other key servers over the network, and provide the other keys to the device group for use to decrypt messages received from other local device groups respectively connected with the other key servers that were encrypted with the other keys and to check message integrity. The multiple key servers may share keys with each other directly, or alternatively, indirectly through a central key server, as needed to support secure communications between their respective device groups.

  • Publication number: 20180013661
    Abstract: One embodiment provides a system that facilitates routing updates outside of a routing protocol. During operation, the system receives, by an intermediate node, a first interest that indicates an originator name which is a routable name prefix for a sender of the first interest and is used by a content producing device in a subsequent interest. In response to not obtaining a matching entry in a forwarding information base (FIB) based on the originator name, the system adds a first entry to the FIB, wherein the first entry includes the originator name as a name for the first entry and further includes an arrival interface of the first interest as an outgoing interface for the first entry. In response to receiving the subsequent interest which has a name that includes the originator name, the system forwards the subsequent interest to the outgoing interface for the first entry.

  • Publication number: 20180013666
    Abstract: One embodiment provides a system for facilitating efficient communication of a collection of interests. During operation, the system receives, by an intermediate node, a first packet which has a name and a first nonce, wherein the first packet indicates a set of member interests, wherein a member interest has a name. In response to not obtaining a matching entry in a pending interest table based on the name for the first packet, the system creates a new entry in the pending interest table, wherein an entry includes a second nonce, a reference count, and a set of arrival nonces and corresponding arrival interfaces. The system sets the new entry's second nonce to a new nonce, and sets the new entry's reference count to a number of member interests indicated in the first packet. The system forwards the first packet, wherein the first nonce is replaced with the new nonce.
