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.

摘要： A system and method for accessing a data network telephony account using a wireless personal information device (PID). The user may connect over the wireless cellular infrastructure to a telephony control server via a data network for access to the user's telephony account, which indicates the user's telephone number in a telephone number entry. Once the connection is made, the user issues a command to set the telephone number entry in the user's data network telephony account to a specific telephone number. The user may then invoke a contacts application in the wireless PID and select a person to call from the contacts list. The user selects the entry to send a command to initiate a telephone connection between the party selected and the user at the telephone designated by the user at the telephony control server.

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： 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： Proximity-based registration of a user to a data network appliance on a data network telephony system. A portable information device, such as a PDA (Personal Digital Assistant) or passive proximity-based security badge, is associated with the user. When the portable information device is brought within a proximity range of a data network appliance, one or more messages are wirelessly transmitted between the portable information device and the data network appliance. The data network appliance then transmits a registration request to a registration server to register the user to the data network appliance. As a result, calls for the user will be routed to the data network appliance to which the user is registered.

摘要： A dial plan for a data network telephony system is provided. A variable-length-code scheme is used to assign communication numeral strings to user identifiers and/or device identifiers, such as SIP URIs (Universal Resource Identifier). The dial plan enables a user to enter a user identifier (or device identifier) into a conventional keypad of a data network telephone, such as an Internet telephony phone. Additionally, embodiments of the disclosed dial plan include techniques for dialing from one data network telephone to another data network telephone utilizing the same service provider, dialing from one data network telephone utilizing a first service provider to a second data network telephone utilizing a second service provider, and dialing from a data network telephone to a PSTN phone and vice versa. The flexible dial plan preferably includes formulating a communication number into a domain portion and a subscriber portion, where the domain portion and the subscriber portion each include a quantity indicator to specify a number of digits making up the remainder of the domain portion, the subscriber portion, or the entire communication portion. Upon accepting an entered communication number from a user, the data network telephone parses the entered communication number into the domain portion and the subscriber portion and accesses database to determine a user identifier or device identifier corresponding to the entered communication number. The data network telephone may then set up a call using the determined user identifier.
