摘要： A diagnostic tool for identifying a configuration of a private network that may disrupt operations involving communication between two devices on the network. The tool, when run on a device in the network, can identify a “double NAT” configuration in which the device may be separated from other devices on the private network by a NAT device. The tool, when run on a computing device, identifies a NAT device, such as a router, to which the device is connected. The tool then identifies a list containing one or more other devices that may be connected to the NAT device. The tool tests whether these other devices also perform NAT functions and are on the private network. Both the NAT device and the devices that may be connected to the NAT device are identified and a determination is made of whether those devices are on the private network by sending requests using one or more protocols that devices on a private network conventionally use but are not conventionally used by devices on other networks.

摘要： To trace an activity through multiple components or applications that may be involved in the performance of the activity, an activity identifier can be generated and utilized by the various components or applications. Each can generate its own activity identifier to minimize changes to existing interfaces. When logging of events has been activated, each application or component can provide, to an event store, an indication of the activity identifier it is using for a given activity. If a preceding or subsequent component utilizes a different activity identifier for aspects of the same activity, a link between the two activity identifiers can be communicated to the event store. Subsequently, examination of the event store can filter out irrelevant entries based on the activity identifiers. A graph linking the various related activity identifiers can be created and only those events associated with activity identifiers not in the graph can be filtered out.

摘要： A network diagnostics system allows determining a root cause for a network problem caused by a local or a remote component of the network, wherein the network diagnostic system may receive the symptoms of such a problem from an application. The network diagnostic system uses a plurality of helper classes, each of the plurality of helper classes providing diagnostic information about an object or a class of objects on the network. Moreover, the network diagnostic system may also use one or more extensible helper classes that are designed to receive information from third party helper classes.

摘要： Systems, methods and computer program products for facilitating the recovery of lost real-time media packets within a computer network real-time application implementing Forward Error Control (FEC), such that server performance is not affected from a CPU and memory perspective, are disclosed. In an embodiment, a conference server that is part of a communication network compliant with the Real Time Transport Protocol (RTP) is able to avoid regenerating FEC packets by not performing any FEC coding operation on the packets unless it is flagged to indicate regeneration via an FEC (e.g., Reed-Solomon) coding is necessary. Absent the flag, the conference server updates the received FEC packet as per the RTP and transmits the packet to its ultimate destination. Such disclosed systems, methods and computer program products are independent of the nature of the media being protected and flexible enough to support a wide variety of FEC techniques.

摘要： It can be determined whether relative one way delay for data packets in a data stream exceeds a delay threshold. If so, then a delay congestion signal indicating that the relative one way delay exceeds the delay threshold can be generated. The delay congestion signal can be used in calculating an adaptive bandwidth estimate for the data stream. A packet loss rate congestion signal may also be used in calculating the bandwidth estimate. It can be determined whether a data stream of data packets is in a contention state. If the data stream is in the contention state, then an adaptive bandwidth estimate can be calculated for the data stream using a first bandwidth estimation technique. If the data stream is not in the contention state, then the bandwidth estimate for the data stream can be calculated using a second bandwidth estimation technique.
