A method for configuring an adaptable circuit breaker chain in a microservices architecture includes transmitting a request from an upstream service to a target one of the services and receiving in a circuit breaker of the upstream service a response from a circuit breaker of the target indicating an inability to provide a response to the transmitted request and including meta-data describing an attempt by the circuit breaker of the target to receive a response from the downstream service to an underlying request of the target necessary to provide a response to the request transmitted by the upstream service. Finally, on condition that the meta-data indicates a delay by the circuit breaker of the target incurred in receiving a response to the underlying request, the method includes changing a pattern of delay imposed by the circuit breaker of the upstream service from a default pattern of delay.

An exemplary golf club head having an increased amount of discretionary mass may be realized by utilizing improved drop angles, an improved average crown height, and/or articulation points. The discretionary mass may be placed low and deep in the club head to improve the location of the center of gravity as well as the inertial properties. A preferred break length may also be utilized to further improve the depth of the center of gravity. In one example, the center of gravity may be positioned to substantially align the sweet spot with the face center of the club head.

A computing system may include a server configured to provide Software as a Service (SaaS) application sessions and at least one client computing device cooperating with the server to run a first one of the SaaS application sessions having a form including an input data field, and generate an application program interface (API) based upon the input data field from the form. The at least one client computing device may further link an output of an Internet of Things (IoT) sensor corresponding to the input data field to the API, and collect data output from the IoT sensor and populate the input data field in the form via the API.

A service request for communication services for communication clients is received. In response, a communication service network is set up to support the communication services. Routing metadata is generated for each of the communication clients. The routing metadata is to be used by each of the communication clients for sharing service quality information with a respective peer communication client over a light-weight peer-to-peer (P2P) network. The routing metadata is downloaded to each of the communication clients. A communication client may exchange service signaling packets or service data packets over the communication service network. When the communication client determines that there is a problematic region in a bitstream received from the communication server, the communication client can request a peer communication client for a service quality information portion related to the problematic region.

A system for processing messages of a high rate data stream and an apparatus including: a message processor including a plurality of processor sub-modules and configured to read an input data stream, process the input data stream, and to output an output data stream; at least one payload memory storing data related to the input data stream and accessible to the message processor; at least one instruction memory accessible to the message processor and storing computer program instructions configuring the message processor to process the input data stream; and an application processor configured to rewrite the at least one instruction memory.

Provided are a transmitting apparatus, a receiving apparatus and controlling methods thereof. The transmitting apparatus includes: at least one processor configured to implement a packet generator which generates a packet including a header and a payload based on a plurality of input packets; and a signal processor which signal-processes the generated packet, and a transmitter configured to transmit the signal-processed packet. A base field included in the header includes a first field set to a first value representing that the base field is a first length or a second value representing that the base field is a second length.

A computer-implemented method and distributed system for maintaining consistency of client applications on a plurality of server nodes may comprise providing a first and second versions of a distributed coordination engine (DConE). The first version of the DConE may receive proposals, reach agreements thereon and generate a first ordering of agreements that specifies an order in which the client applications are to execute the agreed-upon proposals and correspondingly update their respective states. A ChangeVersion proposal may then be processed by the first version of the DConE, whereupon the first version of the DConE may stop reaching any further agreements. A second version of the DConE may then take over reaching agreements on the proposals and generate a second ordering of agreements, beginning with the agreed-upon ChangeVersion proposal. Any agreed-upon proposal, received from the first version of the DConE after the agreed-upon ChangeVersion proposal, may be sent back to the second version of the DConE to enable the second version of the DConE to reach agreement thereon.

A Raman spectroscopic device and a communication method thereof are disclosed. In one aspect, an example Raman spectroscopic device comprises a communication unit configured to communicate with at least one of a server and a management terminal through one or more types of communication interfaces for one or more respective purposes. One or more communication interfaces are established based on a User Datagram Protocol (UDP).

Provided are a transmitting apparatus, a receiving apparatus and controlling methods thereof. The transmitting apparatus includes: at least one processor configured to implement a packet generator which generates a packet including a header and a payload based on a plurality of input packets; and a signal processor which signal-processes the generated packet, and a transmitter configured to transmit the signal-processed packet. A base field included in the header includes a first field set to a first value representing that the base field is a first length or a second value representing that the base field is a second length.
