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. 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.

摘要： A computer network has links for carrying data among computers, including one or more client computers. Packet loss rates are determined for the client computers and, a system of equations is set up expressing the relationship between the loss rates at the client computers and the loss rates at the links. The system of equations is then solved using one or more linear programming techniques, and optimized by making an effort to find the most parsimonious solution.

摘要： An intelligent lookup service for a network is provided for clients of a network requesting services of the network that intelligently determines, based on a service requirement of the requested service, optimal service endpoint(s) for providing the requested service. The intelligent lookup service can incorporate predetermined mapping policy and traffic measurements into the determination. In addition, a feedback loop is provided from clients and/or service endpoints to the lookup service concerning measurements about prior connections in the network. The lookup service can include a set of beacons distributed in the network and against which measurements about the network are recorded. A client receives, from the lookup service in response to a request for a network address, a set of candidate service endpoints that pertain to the requested network address and the client connects to one of the candidate service endpoints based on policy or context.

摘要： An “RFID-Based Inference Platform” provides various techniques for using RFID tags in combination with other enterprise sensors to track users and objects, infer their interactions, and provide these inferences for enabling further applications. Specifically, observations are collected from combinations of RFID tag reads and other enterprise sensors including electronic calendars, user presence identifiers, cardkey access logs, computer logins, etc. Given sufficient observations, the RFID-Based Inference Platform automatically differentiates between tags associated with or affixed to people and tags affixed to objects. The RFID-Based Inference Platform then infers additional information including identities of people, ownership of specific objects, the nature of different “zones” in a workspace (e.g., private office versus conference room). These inferences are then used to enable various applications including object tracking, automated object ownership determinations, automated object cataloging, automated misplaced object alerts, video annotations, automated conference room scheduling, semi-automated object image catalogs, object interaction query systems, etc.

摘要： A client-based collaborative approach called WebProfiler is used for diagnosing Web transaction failures. The WebProfiler leverages end-host cooperation to pool together observations on the success or failure of Web transactions from multiple vantage points. These observations are utilized by a collaborative blame attribution algorithm to identify a suspect network entity that caused the Web transaction failure.

摘要： A computer in a network runs a verification procedure in which it sends data packets to another computer in the network. Some or all of the data packets contain, either individually or collectively, a secret piece of information, such as a secret code. The computer then makes a determination regarding the network links between it and the other computer. If, for example, the other computer is able to respond by providing the secret piece of information back, then the computer sending the data packets concludes that the devices along the network links en route to the other computer are properly forwarding data packets.

摘要： Communication software to aid portable computers monitor, and correct problems accessing a network through a wireless access point. The software controls the exchange of information with other portable computers in the vicinity of the wireless access point. The information exchanged may be used to diagnose problems at the wireless layer, the network layer, the transport layer or the application layer. The information exchanged may provide information about the configuration of computers that successfully or unsuccessfully communicate through the wireless access point. A portable computer receiving this configuration information may compare it to similar information about its own configuration to diagnose problems. Such software may be of particular benefit for portable computers experiencing difficulty connecting to a network at a wireless hot spot.

摘要： Disclosed is a general model and method for computing performance bounds in multi-hop wireless networks. Rather than focusing on computing asymptotic performance bounds under assumptions of homogeneity or randomness in the network topology and/or workload, the present invention accommodates any given network, technology, interference model, routing paradigm, and workload. Using a conflict graph to formally characterize the impact of wireless interference on the performance of multi-hop wireless networks, methods for computing upper and lower bounds on the capacity of a given wireless network are detailed. Besides computing network capacity, the model and method disclosed can also enable or benefit other applications including maximizing fairness and minimizing maximum link utilization.
