628results about How to "Reduce network traffic" patented technology

The present disclosure provides for implementing transaction services patterns. Logical requests are batched for reducing network traffic. A batched request is allowed to indicate that it depends on the response to another request. A single message is sent to all objects in a logical unit of work. Requests that are being unbatched from a batched message are sorted. Independent copies of business data are assigned to concurrent logical units of work for helping prevent the logical units of work from interfering with each other.

A method and system for security monitoring in a computer network has a packet sink with filtering and data analysis capabilities. The packet sink is a default destination for data packets having an address unrecognized by the network routers. At the packet sink, the packets are filtered and statistical summaries about the data traffic are created. The packet sink then forwards the data to a monitor, the information content depending on the level of traffic in the network.

A system, apparatus, and method for providing a distributed location based service system to a mobile user. Information related to a particular geographic location may be electronically transferred to a mobile electronic device, without a request from the user, and interpreted locally on the device in the form of a virtual map of location based resources. The mobile device is capable of determining its location using a GPS (Global Positioning System) or a process of measurement and prediction based on calculation. The mobile device can then use the location information and compare it to available location based resources within the device.

Cached information that includes multiple network addresses is delivered in a manner that changes the order of the network addresses each time the cached information is delivered to a client, thereby achieving load balancing in a manner that reduces network traffic and improves system performance. In the preferred embodiments, the user defines a minimum time to live (TTL) and one or more order change criteria. When a query is made to a DNS, the DNS returns an answer that includes a time to live (TTL). This answer may be stored in a cache, and may include multiple network addresses. If the TTL for the answer received from a DNS is less that the minimum TTL, the TTL for the answer is set to the minimum TTL before storing the answer in the cache. When a query may be satisfied by a cached answer that includes multiple network addresses, a cache mechanism delivers the multiple cached network addresses in an order determined by the one or more order change criteria if the TTL for the cached results is a positive number. In this manner load balancing can be achieved while still benefitting from the performance enhancements of caching DNS query results.

Systems and methods are described for interactively and graphically interfacing with a user on an HVAC system controlled by a thermostat. The user interface is implemented on a touch screen display on a remote wirelessly connected device such as smartphone or a tablet PC. The interface displays a screen that mimics the display on the thermostat including allowing one or more input methods that are analogous to input methods used on the thermostat. Touch screen gestures such as touch and drag, touch and hold and tapping are used in an intuitive way. The user experience is enhanced by allowing large-scale changes while reducing the risk of sudden unintended changes. The control signals are judiciously tailored to protect the HVAC equipment from unwarranted over-controlling, reduce unnecessary network traffic, and prevent the waste of energy.

In one embodiment web page response time is improved by requesting multiple resources in a batch request, receiving said resources in a batch response, and disjoining the resources and corresponding HTTP headers before caching on the client. The resources are retrieved by web browser from the cache separately without loss of cache granularity. Client parses base page to determine the embedded resources and includes in the batch requests only web addresses those resources that are uncached or may be expired. To reduce required bandwidth, server validates caching information of every resource before sending the batch response. In another embodiment web application performance for mobile users is improved by combining individually requested resources into the batch response on a network node positioned on a link between cellular network and the Internet.

Disclosed is a system for queuing elements, such as print jobs. A processing unit receives an element that is associated with a first factor and a second factor, such as data type and a priority within the data type, that indicates a priority of the element. For each first factor and second factor pair, an entry point addresses a point in the queue associated with the first factor and second factor. The processing unit locates an entry point addressing a point in the queue associated with a first factor and second factor that matches the first factor and second factor associated with the received element. The processing unit then inserts the received element in the queue at the entry point.

A seamless solution transparently addresses the characteristics of nomadic systems, and enables existing network applications to run reliably in mobile environments. The solution extends the enterprise network, letting network managers provide mobile users with easy access to the same applications as stationary users without sacrificing reliability or centralized management. The solution combines advantages of existing wire-line network standards with emerging mobile standards to create a solution that works with existing network applications. A Mobility Management Server coupled to the mobile network maintains the state of each of any number of Mobile End Systems and handles the complex session management required to maintain persistent connections to the network and to other peer processes. If a Mobile End System becomes unreachable, suspends, or changes network address (e.g., due to roaming from one network interconnect to another), the Mobility Management Server maintains the connection to the associated peer task—allowing the Mobile End System to maintain a continuous connection even though it may temporarily lose contact with its network medium. In one example, Mobility Management Server communicates with Mobile End Systems using Remote Procedure Call and Internet Mobility Protocols.

A method and apparatus for providing distributed control of a home automation system is provided. Each device participating in a home automation system is equipped with control logic for providing distributed control. Through the control logic, each device maintains scene definitions describing the state of the device for each scene in which it participates. When any device in the system receives a request to launch a scene, such as a button press on one of the devices, the device broadcasts a scene state change message to all devices within the home automation system. The scene state change message identifies to each device a particular scene that should be launched. Each device in the system receives the message and determines whether the device is a participant in the scene. If the device is a participant in the scene, the device adjusts its state according to a scene definition stored in the device associated with the scene. The device may adjust a controlled electrical load, such as a light, according to the scene definition by turning the load on, off, or setting the load to some intermediate value.
