Systems and methods are provided that enable high-performance Internet access on board moving vehicles. In an illustrative implementation, an exemplary wireless data communications environment comprises a PluriBus module, an instruction set comprising at least one instruction set to process data for wireless communication between a cooperating component onboard a moving vehicle and other cooperating wireless components, and one or more multiple wide-area wireless communications links. In an illustrative operation, the PluriBus module can perform one more wireless communications techniques comprising opportunistic erasure coding such that coded packets can be sent in the event that there are openings in the one or more wireless communication links' capacity and transmitting the data packets along the one or more wireless communications links that is estimated (e.g., in real time) to offer efficient delivery of data packets.

A electronic communication system that can detect and adapt to delays in delivery of e-mail messages. The system may adapt to delays by using other mechanisms to convey the information intended for delivery by e-mail. Though, other reactions to delays are possible, including rescheduling events premised on delivery of information by e-mail. The system may use a low-latency notification channel in parallel with a channel used for e-mail delivery to detect actual delays for a specific e-mail message. Additionally, the system may detect potential delays based on historical delay information or other information indicating that a path over which an e-mail is to be sent may be experiencing delivery delays and may adapt to a potential delay before a message likely to experience the delay is sent.
摘要:
A electronic communication system that can detect and adapt to delays in delivery of e-mail messages. The system may adapt to delays by using other mechanisms to convey the information intended for delivery by e-mail. Delays may be detected using a low-latency channel to send notifications of e-mails to recipients. The notifications are likely to be received in advance of a delayed e-mail, allowing an intended e-mail recipient to detect that delivery of an e-mail has been delayed. The recipient may adapt to the delay in delivery, when a notification is received without a corresponding electronic mail message. The notification may be small relative to an e-mail message but may include enough information to allow the recipient to identify the subject matter of the corresponding e-mail message, an importance level of the e-mail message, a preferred mechanism of the sender for out-of-band communications, and/or the location from which the e-mail was sent.

Notifying a user that an email message sent to the user was not received by the user. Users can register to receive notifications. When a sender sends an email message to a recipient, a separate notification also may be sent to a notification server that populates and controls access to an email notification list. Each notification in the list may comprise a hash of the content of the email message that it represents. A recipient module may be configured to check the notification list periodically and/or in response to a recipient's instructions, and compare notifications to the email messages received for the recipient to determine whether any email messages intended for the recipient were not received. If it is determined from the notifications that an email message was not received, a notice may be sent to the sender, which may include a request that the sender re-send the email message.

Methods and systems for dynamically providing application analytic information are provided herein. The method includes inserting instrumentation points into an application file via an application analytic service and dynamically determining desired instrumentation points from which to collect application analytic data. The method also includes receiving, at the application analytic service, the application analytic data corresponding to the desired instrumentation points and analyzing the application analytic data to generate application analytic information. The method further includes sending the application analytic information to a client computing device.

The functionality described herein allows a user device to determine an appropriate juncture at which to initiate processing within a global navigation satellite system (GNSS) dead zone in an energy-efficient manner. In one implementation, the functionality employs a sensor management module for determining when to activate a device movement sensor module provided by a user device. When activated, the user device uses the device movement sensor module to perform any environment-specific processing, such as a dead-reckoning process for determining incremental positions within the venue. Further, in a crowd-sourcing application, the user device may report the incremental positions together with beacon information to remote processing functionality.

In one kind of DoS attack, malicious customers may try to send a large number of filter requests against an innocent customer. In one implementation, a Filter Request Server (FRS) may allow a customer against who a filter request is made to dispute the implicit accusation of the filter request or stop sending malicious traffic. If the customer claims innocence, the FRS may log destination addresses of data packets sent by the customer and identify and ignore false filter requests if these filter requests come from customers who do not correspond to one or more of the destination addresses that have previously been logged by the FRS.

This document relates to a distributed network coordinate system. One implementation provides computer-readable storage media including instructions that may cause a processor to perform certain acts. For example, the acts may include storing an initial network location of a first device in a network. The network may include the first device and a second device. The acts may also include monitoring one or more network performance metrics related to existing application communications with the second device, and determining an updated network location of the first device, based on the initial network location and the network performance metrics. Aspects of network health can be derived from monitoring changes in the network locations of various devices within the coordinate system.

Methods and systems for reducing network usage of a computing device are provided herein. The method includes receiving a network call relating to a network transfer from an application at an application programming interface of the computing device. The method also includes determining whether the network transfer is relevant to a current state of the application and procrastinating the network transfer if it is not relevant to the current state of the application.

The description relates to mobile device location. One example can identify global navigation satellite system (GNSS) satellites expected to be in line-of-sight of a mobile device. This example can detect differences between received GNSS data signals and expected GNSS data signals from the expected GNSS satellites. The example can also determine a direction from the mobile device of an obstruction that is causing at least some of the detected differences.
