Method and device for performing asynchronous operations in a communication system
Embodiments herein include a method for concurrently performing asynchronous operations over IPv4 and IPv6 in a mobile device. The method includes capturing a DNS query-pattern of a plurality of DNS queries for a plurality of services of an application in the mobile device. Further, the method includes performing a DNS lookup in a DNS cache, to obtain a DNS resolution over the IPv4 and the IPv6 based on the DNS query-pattern of the plurality of DNS queries for the plurality of services of the application. Further, the method includes storing the DNS resolution based on the DNS lookup in the DNS cache. Further, the method includes triggering a TCP connection using a pre-connected connection descriptor based on a domain name resolution. Further, the method includes storing the pre-connected connection descriptor corresponding to the TCP connection in a connection pool cache.

Point value change notification
Methods, devices, and systems for point value change notification are described herein. One system (100) includes a message broker (108) to receive data from a data acquisition (DAQ) system, a first building management system (BMS) instance (104) connected to the message broker (108) to process a first portion of the DAQ data, a second BMS instance (104) connected to the message broker (108) to process a second portion of the DAQ data, and a web application (118) connected to the message broker (108) to generate a notification of a change in point value of a portion of the first portion or the second portion of the DAQ data, where the first BMS instance (104) and the second BMS instance (104) are provisioned with a plurality of computing resources deployed in a computing environment (102, 502) and are ultimately executed on hardware.

NETWORK SWITCHING WITH CO-RESIDENT DATA-PLANE AND NETWORK INTERFACE CONTROLLERS
A system with co-resident data-plane and network interface controllers embodying a method for network switching of a data packet incoming from a network at a packet input processor portion of a network interface resource comprising the packet input processor, a packet output processor, and a network interface controller, implemented as a module or a single chip, to a target entity via either the network interface controller or the packet input processor is disclosed.
Secure online transactions
A user device and a server conduct a secure online transaction. The user device transmits received user login and credentials to the server, as well as one or more properties of the user device, such as a list of applications stored on the user device. The server transmits one or more restrictions back to the user device, such as which ports to close, which applications to close, and what features of applications and the operating system should be limited during the transaction. After implementing the restrictions, the user device and the server conduct the online transaction. A unique ID may be transmitted throughout the transaction and the unique ID may be a hash. After the transaction, the user device purges transaction data, restores normal operation, and notifies the server. The transaction may be conducted in a second tunnel and the other communication via a first tunnel.
Establishing data channels between user devices and remote systems
Techniques for establishing communication channels between user devices experiencing network connectivity issues and remote communication systems are described herein. The techniques include the use of a secondary device to act as a proxy, or a “middle man,” to facilitate the communications with the user device. A user device may detect lack of network connectivity, and begin broadcasting advertisement messages that indicate the lack of connectivity. A secondary device may detect the advertisement message, and send a discovery message to a connectivity system indicating that it detected the advertisement message. The connectivity system can provide this information to a remote communication system, and the remote communication system can establish a connection with the secondary device and instruct the secondary device to establish a connection with the user device. The remote communication system then has a communication channel with the user device, using the secondary device, to troubleshoot the user device.

System and method for recovery of data packets transmitted over an unreliable network
A system and method is provided that enables the recovery of data packets transmitted over an unreliable network. The system and method utilize an algorithm for transmitting the data packets with restoration of lost data during data transfer over UDP Protocol encrypted with DTLS Protocol. Advantageously, the algorithm does not require changes to data for either UDP or DTLS packets, but rather a separate, specifically designed packet is transmitted to the recipient to facilitate and ensure the recovery of any lost data packets over the unreliable network.
