Abstract: Accountability among Autonomous Systems (ASs) in a network ensures reliable identification of various customers within the ASs and provides defensibility against malicious customers within the ASs. In one implementation, reliable identification is achieved by implementing ingress filtering on data packets originating within individual ASs and defensibility is provided by filtering data packets on request. To facilitate on-request filtering, individual ASs are equipped with a Filter Request Server (FRS) to filter data packets from certain customers identified in a filter request. Thus, when a requesting customer makes a filter request against an offending customer, the FRS within the AS to which the offending customer belongs conducts on-request filtering and installs an on-request filter on a first-hop network infrastructure device for the offending customer. Consequently, the first-hop network infrastructure device filters any data packet sent from the offending customer to the requesting customer.

Abstract: A path progression matching system and method that uses path progression to find a current position of a mobile device in an indoor environment and a path history to find the path of the mobile device to get to the current position. Embodiments of the system and method use path history information, constraints, and optimization measures such as the use of received signal strength indicator (RSSI) weighted correlation coefficients. Embodiments of the system and method include a unified probabilistic model that uses path history and allows multiple constraints to be applied simultaneously. Embodiments of the system and method also include a path progression module having a first-stage progression module, which finds a starting location for the path progression matching, a second-stage module, which begins building a path history, and a third-stage progression module, which uses the path history to find the current position and path.

Abstract: Embodiments calculate an estimated latency between computing devices. A latency service aggregates latency records defining latency measurements and corresponding latency factors from a plurality of computing devices. From the aggregated latency records, the latency service defines relationships between the latency measurements and the corresponding latency factors. Responsive to a request for an estimated latency from a mobile computing device, the latency service applies the defined relationships to estimate the latency based on the latency factors associated with the received request. In some embodiments, the estimated latency includes three portions: a first latency value representing the latency from the mobile computing device to a cell site, a second latency value representing the latency from the cell site to an access point, and a third latency value representing the latency from the access point to a destination computing device.

Abstract: A home device management technique is described that allows a user to manage a network of distributed home devices. Special application modules, driver modules, and service exchange ports are employed. Each application modules implements some functionality in the home, preferably using one or more devices in the home distributed system. Each driver module provides the logic for operating one or multiple distributed home devices and is capable of receiving commands from application modules and sending them to devices, detecting events for an associated type of home device, translating the detected event into a format usable by the application modules and notifying the application modules of the events. Events are communicated between the application modules and the driver modules by using one or more service exchange ports. Access control policies are employed to control access to the home devices.

Abstract: 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.

Abstract: Methods, articles, and systems for determining a probable cause of a component's abnormal behavior are described. To determine the probable cause, a computing device computes, for one or more pairs of components having dependency relationships, a likelihood that behavior of one component of a pair is impacting behavior of the other component of the pair. This computing is based on joint historical behavior of the pair of components. The computing device then determines that one of a plurality of components is a probable cause of the abnormal behavior based on the computed likelihoods.

Abstract: Called parties in an enhanced communication system are provided location information associated with a calling party to help them determine whether they should accept the call. Alternatively, automatic call routing may be performed based on location context information associated with the calling party such as whether the caller is calling from a regular location association with him/her or an extra-ordinary location.

Abstract: Described herein is a system that includes a location determiner component that receives a first geographic location of a personal computing device of a first individual, wherein the first geographic location is indicative of a current geographic location of the first individual. The system also includes an estimator component that receives a second geographic location that is different from the first geographic location. The estimator component determines an estimated time of arrival for the first individual at the second geographic location based at least in part upon the received first geographic location, wherein the estimator component outputs the estimated time of arrival to a second individual.

Abstract: 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.

Abstract: 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. The mechanism may convey the information to the recipient once the delayed electronic mail message is received by the recipient's e-mail system. In this respect, the recipient may make arrangements to receive information in the e-mail message when the recipient expects to be away from his or her e-mail system. Additionally or alternatively, the recipient may choose to initiate out-of-band communication to the sender when the recipient receives an indication of a delayed electronic mail message.
