A method for sending an ACK from the receiver to the sender is disclosed. The receiver starts an ACK timer with the ACK timeout value being smaller than the RTX timeout value. The ACK timer is stopped or cancelled when an ACK is sent from the receiver to the sender. When the number of the delayed ACK for I-frames is close to the receive widow size of the receiver or the ACK timer is timeout, the receiver sends an ACK to the sender actively. When the receiver receives a Poll frame from the sender due to RTX retransmission timeout, the receiver sends an ACK to the sender passively. The receiver adjusts the ACK timeout value used next time based on the following: timeout value of a current ACK timer, RTX timeout value of the sender, the receive widow size of the receiver and the number of I-frames for which ACKs have not been sent, in order to reduce the S-frames and stops of data transmission, thus improving the data transmission speed and the bandwidth utilization.

The present invention relates to systems and methods for employing a trigger based mechanism to detect changes in a database table, providing a notification when the database table changes and registering to receive the notification. The systems and methods employ a listeners table to store information associated with registered database tables. Alter a database table changes, a trigger mechanism associated with the database change facilitates a search of the listeners table for a parameter associated with the changed database table. If the changed database table is registered, the information from the listeners table is provided to a delivery service which transmits a message indicating the registered database table changed. After receiving the message, a notification runtime service can route a notification to a client(s) registered to receive the notification. The foregoing mitigates performing time intensive queries and utilizing inconsistent query results.

The invention relates to an Internet of Things data acquisition and monitoring control system, and belongs to the Internet of Things field. The invention invents a method for designing and realizing small configuration software by means of SVG vector diagram, combines the configuration software with the traditional SCADA system structure, and realizes a visual new generation SCADA system with bothDT (Desgin Time) and RT (Run Time) states. Aiming at the requirement of real-time data processing by monitoring configuration software, a real-time data receiving and pushing function based on RabbitMQ in Ruby on Rails environment is designed. And an improved LZW algorithm is proposed to deal with the huge amount of historical data generated by SCADA system. The invention is of great significancefor the management and control of equipment and information of road networks, such as high-speed railway and urban railway stations.

The invention relates to a restaurant member order payment management method and system based on a barcode. The method is characterized in that a server lists bookable table numbers so that a user can select an appropriate table autonomously according to a demand; a user terminal directly gets access to the server of a restaurant by scanning a user barcode in order to prevent a step of inputting an account number and a password; the booking information of a member can be located as long as the user shows a member barcode to a service scan terminal when arriving at the restaurant, thereby achieving convenient query; the service terminal can display a menu and generates a total price automatically after selection; the user can choose online payment, and payment can be completed by scanning a generated payment two-dimensional code. The method and system are safe in payment, avoid counterfeit money and, are convenient, and eliminate queuing and change making.

The invention provides a wide and narrow band system interconnection method and device, and the method comprises the steps: respectively monitoring target information in a narrow band system and a wide band system; wherein the target information comprises online and offline states of the interconnection number and a current call group; under the condition that the state of any interconnection number in the narrow-band system and the broadband system is switched from offline to online, registering a mapping number of the interconnection number to a system where the interconnection number is located; under the condition that the calling group to which any interconnection number belongs in the narrowband system and the broadband system changes, updating the calling group to which the mappingnumber of the interconnection number belongs; and when a call is received, responding to the call according to the online and offline states of the interconnection number and the mapping number and the current call group. According to the method and the device, the problems that the next call response time is relatively long in some scenes (for example, the destination end is offline) and resources are wasted in the process of allocating resources to the group call can be solved.

The invention discloses a caching method for reading and writing massive user and post data in a part-time post recommendation system, which is characterized in that multiple types of data exist in a recommendation system link, the storage mode of the data in a memory is reasonably divided, and the data are loaded as required; data is respectively stored in a JVM in-heap memory, a JVM out-heap memory and a large-scale distributed cache according to business characteristics and data magnitude of the data in a recommendation system.
