Abstract:
A method for transporting private line traffic, comprising the steps of:multiplexing a first plurality of Time Division Multiplexing (TDM) private line circuits into a first real time variable bit rate (rt-VBR) virtual circuit such that the bandwidth of the first rt-VBR virtual circuit is not limited and such that a TDM frame without data is not transported over the first rt-VBR virtual circuit; multiplexing a second plurality of TDM private line circuits into a second rt-VBR virtual circuit such that the bandwidth of the second rt-VBR virtual circuit is not limited and such that a TDM frame without data is not transported over the second rt-VBR virtual circuit; combining the first and second rt-VBR virtual circuits for transport over a packet network; monitoring the utilization of the packet network link; and invoking an overload algorithm when the packet network link utilization exceeds a threshold value.
