Systems and methods of routing IP telephony data packet communications

摘要

Systems and methods for determining quality measures for communication paths that can be used to conduct telephony communications determine and record quality measures for each of a plurality of paths during different times of the day and different days of the week. This information is used to determine and record measures of how the quality of each path varies over predetermined periods of time. When it is necessary to select a path for the setup of a new telephony communication, information regarding the anticipated quality of different potential paths, and information regarding how that quality is expected to vary over the duration of the telephony communication are used to select a path for the telephony communication.

主权项

1. A method of providing one or more preferred paths for transmission of digital data packets bearing the media of an Internet protocol (IP) telephony communication, comprising:
obtaining, with at least one processor, information about the respective quality of each of a plurality of paths that can be used to communicate data packets bearing IP telephony communications, wherein the obtained information includes, for each of the plurality of paths, a first quality measure that is indicative of the average quality provided by the path over a predetermined period of time in the past, and a second quality measure that is indicative of how much the quality of the path varied over that same predetermined period of time; receiving a request for an identification of at least one path that can be used for an IP telephony communication; and identifying, with at least one processor, at least one path for the IP telephony communication based on the obtained information.
