55results about How to "Improve delivery reliability" patented technology

A communication node of the present invention automatically transmits original and duplicate packets over different paths in a communications network to improve delivery reliability of the packet and to decrease packet delivery time. A packet is typically marked for reliable transmission by the application layer of a source node, while a routing agent module within the node IP layer processes the marked packets. The marked packets are transmitted over redundant (e.g., primary and secondary) network paths from the source node to the destination node. The primary path is usually the shortest path between the source and destination nodes, while the secondary path is selected to avoid overlap with the primary path. The application or transport layer of the destination node filters or removes plural copies of received packets.

Described herein are—among other things—systems, methods, and apparatus for accelerating and increasing the reliability of content delivery by serving objects redundantly over multiple paths from multiple servers. In preferred embodiments, the decision to use such multipath delivery is made on the server side. A content server can modify or generate a given web page so as to invoke multipath, e.g., by injecting markup language directives and / or script instructions that will cause the client device to make multiple requests for a given object on the page. Preferably the multiple requests are made to separate content servers in separate points of presence. The teachings hereof may be advantageously implemented, without limitation, in intermediary servers such as caching proxy servers and / or in origin servers.

The invention relates to a guide roller limiting detection device. The guide roller limiting detection device comprises directional plates which are arranged between two opposite side plates, and a guide roller; the guide roller is located between the two directional plates; a mounting supporting seat located between the two side plates is fixedly connected to the guide roller; the mounting supporting seat is arranged in sliding grooves on inner sides of the directional plates in a sliding manner; one end of the guide roller penetrates through the side plate to be connected with a hand wheel, and a locking sleeve is arranged on the guide roller and located on an outer side of the side plate. According to the guide roller limiting detection device, the hand wheel is turned to adjust a position of the mounting supporting seat on the guide roller, thereby limiting a guiding position of a thin film and preventing shifting of the thin film from a center position, and therefore, the reliability of conveying of the thin film is improved.

The invention provides a door sheet system for a water-tank-type cleaning device, and belongs to the technical field of kitchen appliances. The problem that cleansers are inconveniently put in an existing dishwasher is solved. The door sheet system for the water-tank-type cleaning device comprises a face plate and a cleanser putting device, wherein a door shaft sleeve is installed on the face plate, a fixing shaft and damping assemblies are installed in the door shaft sleeve, the damping assemblies are connected to the face plate, and the face plate rotates around the damping assemblies; the cleanser putting device comprises a storing box, a cover and a driving device, a liquid storing cavity is formed in the storing box, a connecting pin is installed on the storing box, a torsional spring is installed on the connecting pin, the cover is hinged to the connecting pin, the torsional spring abuts against the cover, the driving device is installed in the face plate, a shaft rotating switch is installed on an output shaft of the driving device, the cover is buckled to the storing box in a sealed mode, and the shaft rotating switch rotates to control the cover to be automatically opened. The door sheet system has the advantages that the cleansers are conveniently put, and the door sheet reliably rotates.
