Abstract: A technology is provided for reducing latency in a messaging system. Unprocessed messages in a message queue are consumed via a messaging overflow service launched in response to an alarm triggered by a monitoring service that indicates the message queue has reached a predetermined threshold. The unprocessed messages are processed via the messaging overflow service to generate a processed data store values. The processed data store values are stored in a cache associated with the messaging overflow service.

Abstract: A method implemented by a switch in a Software Defined Networking (SDN) network to trace packets in the SDN network, where the switch includes a packet processing pipeline. The method includes receiving a first packet, determining, at a first flow table of the packet processing pipeline, whether the first packet is to be traced, punting a copy of the first packet to an SDN controller and directing the first packet to a second flow table of the packet processing pipeline in response to a determination at the first flow table that the first packet is to be traced.

Abstract: A method for service function chaining within an end-to-end path of a network connection between a source and destination node includes: executing, for a defined service function chain including an ordered sequence of network service functions, an address resolution process that translates names of the network service functions of the defined service function chain into their corresponding IP addresses. The address resolution process is performed at a name server of the destination node by a sequence of name server queries sent in succession to respective name servers of each of the selected network service functions of the defined service function chain in accordance with their order. Each of the name server queries is answered by a response from a name server of the respective network service function that includes IP addresses of selected instances of a respective network service function chosen by the respective name server according to predefined criteria.

Abstract: The described technology relates to a logging framework wherein identifiers are associated with various elements within a web application, such as pages within the application and portions of pages within the application. Additional identifiers may be associated with sessions within the application, instances of page visits within the application, and other facets of the application and user interactions with the application. The identifiers can be used to generate a log that indicates, among other information, a history of interactions performed by a user navigating the application.

Abstract: Systems and methods for maintaining session identifiers across multiple webpages for content selection are described herein. A server can generate a session identifier corresponding to the client device for use in selecting content to be served across the information resources of a content publisher. The server can then receive, from the client device, a request for instructions to insert into a header of an information resource for selecting a content provider. The server can determine that the request includes the session identifier that matches the one generated for a previous request. The server can obtain a parameter value for each content provider with the session identifier. The server can select a content provider using the parameter values. The server can provide a script to the client device for the header. The script can be configured to cause the client device to obtain a content item from the selected content provider to insert into the information resource.

Abstract: A scheme for modulating an adaptive bitrate (ABR) streaming client engaged in a current ABR streaming session.

Abstract: A method for operating a server device in a system is disclosed. The server device determines a current process value of at least one process parameter of a process controlled by the system and transmits the determined current process values to a plurality of client devices in the system for each process parameter or a subset thereof via a data network. According to the invention, the server device forms a variable group for at least one process parameter which is to be transmitted to more than one of the client devices. The server device then combines in each case the current process values of the at least one process parameter in the variable group at the different transmission times to form a single multi-target message and at the different transmission times to form a single multi-target message and transmits the multi-target message to a group address in the data network.

Abstract: Certain aspects of the disclosure are directed to providing aggregated context information in a data communications network. According to a specific example, a data communications server can operate to provide user-data communications sessions each involving a client-specific endpoint device and another participating endpoint device, where the client-specific endpoint device is associated with a client-entity among a plurality of remotely-situated client entities. User-data communications between the client-specific endpoint device and the other participating endpoint device can be retrieved from a plurality of disparate interconnected data communications systems, where the data communications systems each provide at least one data communications service to the client entity on a subscription basis.

Abstract: Disclosed are methods, systems and apparatus for resuming a transmission link. The method may comprise: if a connection between a first server and a third server that are adjacent to each other in a transmission link is interrupted, a second server serving as a next node of the third server sends a breakpoint resuming request to the first server; on the condition that the first server and the second server mutually determine that the resuming condition between the two is satisfied, the first server establishes a compensation connection egress port of the first server to an ingress port of the second server; and resumption is performed through the compensation connection. The abnormal connection in the transmission link can be compensated and resumed through a node in a private network, so that the idle processing capacity of each node can be utilized, and the utilization rate of processing resources can be improved.
