  • Method and system for controlling link saturation of synchronous data across packet networks
    Patent number: 8472315
    Abstract: A method for controlling admissions of data packets across a packet network comprising the steps of establishing a communication route along a plurality of interconnected secondary nodes, determining an amount of available network and determining whether to admit the data packets to the communication route based on the determined amount of available network bandwidth. Also disclosed is a system for implementing the method comprising a first provider edge element, a second provider edge element, a plurality of interconnected secondary nodes disposed between the edge elements. Each of the secondary nodes comprises at least one first detection device for determining an amount of available network bandwidth and at least one admission device in communication with the respective first detection device for determining whether to admit the data packets to the communication route based on the determined amount of available network bandwidth.
