摘要： A system for adjusting or establishing transmission fees based on delay and/or jitter. A network element may evaluate transmission delay and/or jitter over a given transmission system, which may be or is in effect for a particular real-time media transmission. A determination may then be made whether the delay and/or jitter exceeds a predetermined threshold, which may suggest that the transmission quality would be lower than desired. If so, then the fees that a billing entity would charge for the transmission may be decreased in view to account for the lesser quality of service. Conversely, where the delay and/or jitter is lower than a predetermined threshold, then the billing entity may increase its fees accordingly. Other fee schedules based on delay may be established as well.

摘要： A mechanism for forward error correction (FEC) coding, suitable for use where multiple payload streams are simultaneously transmitted from end-to-end. Instead of deriving parity information based on payload information carried within a given stream, the invention involves FEC encoding across multiple parallel streams and thereby deriving parallel parity information. The parallel parity information may then be transmitted to the receiving end in parallel with the underlying payload information. Beneficially, the invention can substantially reduce the time it takes for the transmitting end to derive parity information or for the receiving end to receive the information necessary to recover from data loss. The invention is especially suitable for use in IP telephony and particularly for implementation in an IP telephony gateway.
摘要翻译：用于前向纠错（FEC）编码的机制，适用于从端到端同时发送多个有效负载流的情况。本发明不是基于给定流中携带的有效载荷信息导出奇偶校验信息，而是涉及跨多个并行流的FEC编码，从而导出并行奇偶校验信息。然后可以将平行奇偶校验信息与底层有效载荷信息并行发送到接收端。有利地，本发明可以显着地减少发送端导出奇偶校验信息所需的时间，或者为了接收端接收从数据丢失恢复所必需的信息。本发明特别适用于IP电话，特别适用于IP电话网关中的实现。

摘要： A method and apparatus for measurement-based conformance testing of service level agreements in networks. The method includes first collecting quality of service information from network traffic over a plurality of network nodes. Then, the collected quality of service information is compared to a plurality of specified quality of service levels. A plurality of possible virtual quality of service pathways through a plurality of network nodes is provided, based on the compared quality of service information. One embodiment of the method includes the additional step of creating a virtual connection using the compared quality of service information. In another embodiment of the method, the step of collecting quality of service information from network traffic over a plurality of network nodes includes first transmitting test traffic from a source to a destination over a plurality of network nodes. The transmitted test traffic is then received at the destination, and quality of service information is identified by comparing characteristics of the test traffic transmitted by the source to characteristics of the test traffic received by the destination.

摘要： A toll saving method and apparatus for a remote access system is provided. A first communication device receives a connection request from a second communication device. The first communication device then decodes caller identification information from the connection request to determine a user identity, without completing the connection request. The first communication device determines whether an event associated with the user identity has occurred. If the event associated with the user identity has not occurred, the connection request is not completed. In a preferred embodiment, the toll saving method and apparatus allows an email user to call an ISP to determine whether unaccessed email is present in the user's account. If no email is present in the user's account, the call is never answered and no toll charges are incurred.

摘要： A system for dynamically jitter buffering a sequence of packets based on substantially synchronized time signals maintained at the transmitting and receiving ends of a communication system. The time signals may be synchronized, for instance, by equipping both the transmitting and receiving ends with global positioning system receivers. The transmitting end may mark each outgoing packet with a sender-time based on the time signal at the transmitting end. Dynamic jitter buffering may then be provided by scheduling delayed play-out of each packet. For instance, the jitter buffer at the receiving end may be configured to delay play-out of each packet until the time signal at the receiving end indicates a time that is substantially a predetermined end-to-end delay period after the sender-time for the packet.

摘要： A method for improving perception of electronic content from a computer network such as the Internet or an intranet. Network latencies and the type of electronic content such as text, graphical images, animation, voice, video and other electronic content interact to influence user perception of the quality of information provided. As network latency increases and becomes more variable, users typically become less satisfied. The method dynamically adjusts the amount of electronic content presented to user based on a determined network latency. The amount of electronic content is also adjusted progressively and underlying transport protocol such as Transmission Control Protocol (“TCP”) and User Datagram Protocol (“UDP”) are adaptively adjusted based on the type of electronic content requested (e.g., TCP for text, UDP for graphical images, etc.). The method may improve user perception of requested original electronic content by dynamically sending an amount of original electronic content based on a determined network latency. Improved user perception of original electronic content may help attract and retain, students, customers, contributors, etc. to an organization's electronic content site on a computer network (e.g., a home page on the Internet or an intranet).

摘要： Gateway routers for real-time networks have the ability to collect delay, loss, and jitter statistics on a per-connection basis. It is possible to use this information not only to monitor the quality of individual voice calls and other real-time connections, but also to evaluate the overall performance of the underlying network. This paper describes a method for monitoring and managing the performance of a real-time data network that supports voice, video and other real-time services. In the described embodiments, the RTCP mechanisms of RTP for sender and receiver reporting be used to relay performance information to one or more network monitoring sites for analysis and interpretation. In addition, gateway routers are organized and managed within a hierarchy that allows the monitoring function to localize it view of network conditions within the hierarchy; and the monitoring of network performance can occur on various time scales.

摘要： A system and method for providing telephone service to a user of a telecommunications device using a data network service provider. The data network service provider has a local service host that is accessible by a local access identifier. A caller uses a telecommunications device to dial the local access identifier to connect to the local service host. In response to a prompt, the caller dials a telephone extension that identifies the callee's telecommunications device. The local service host receives the telephone extension and verifies that the callee is a subscriber. The local service host then retrieves the gateway nearest the callee telecommunications device and opens a voice-over-data channel between the callee and caller gateways. The telephone conversation then proceeds between the callee and caller telecommunications devices over a public switched telephone network connection to the caller gateway, the voice-over-data channel and the PSTN connection to the callee telecommunications device.

The location identifier may provide address information, latitude and longitude configuration, directions, or other information. In one embodiment of the present invention, the location information is communicated in a data communications channel between the caller and the callee. In another embodiment of the present invention, the location information is communicated to the caller during call setup. The embodiments of the present invention are useful in providing emergency dispatch services, such as 911 in a data network telephony system.
