  • Patent number: 8094559
    Abstract: This document describes tools that enable data network equipment to use its permitted data rate or physical maximum rate even if one of its links fail or it transmits more data on some links than others. To do so, the tools may track how much of a permitted data rate is used by a group of physical links. If the group is using more than the permitted data rate, the tools may limit the group to that rate. If some of the physical links in the group fail, the tools enable the group to use either its permitted data rate or the physical maximum rate of the group. In addition, the tools allow unique permitted data rates in two directions by a group of physical links. The tools may be used at ingress or egress modules within equipment depending upon the application and implementation.

  • Patent number: 8095008
    Abstract: The present invention provides systems and methods to convert a reconfigurable optical node multiple-input multiple-output (MIMO) system to a single-input single-output (SISO) system suitable for a proportional-integral-differential (PID) control process. Advantageously, the present invention allows PID control to apply to a MIMO optical node by modeling the node as two SISO systems. The present invention optimizes the division of gain and loss between components in the reconfigurable optical node. This provides means to control the net gain and loss of a series of components when the component chain being controlled includes those components that have a single action affecting multiple channels and components that affect only one channel. The present invention utilizes control of a single quantity of amplifier gain minus attenuation for each channel, and the coupling together of all channels in the amplifier which makes the channels inter-dependent.

  • Patent number: 8095342
    Abstract: The present invention provides systems and methods for highly efficient bit error rate (BER) modeling in quasi-linear communication networks. In the present invention, nonlinear noise is treated within a linearization approach along with the amplified spontaneous emission (ASE) noise, and the nonlinear noise is considered as another source of noise in addition to the ASE noise. This enables a quasi-analytical approach to the BER calculation. First, a covariance matrix is analytically computed. An equation is derived for a noise component of a signal and an implicit analytical solution is found depending on the signal and system parameters. Second, probability distribution functions (pdfs) are computed for the signal. An analytical calculation is performed of the characteristic function for the noise statistics. Next, a numerical computation of the Fourier transform of the characteristic function is performed to yield the pdf, and numerical integration is performed on the pdfs to yield the BER.

  • Patent number: 8059685
    Abstract: The present invention reserves special Ethernet timing packets to mark timing within Ethernet and OTN, and secondarily creates frames within the Ethernet stream through the timing marker packets. The result is standard Ethernet with timing capability that can be transported over standard Ethernet links and/or within OTN. This timing capability can be utilized to carry synchronization over asynchronous Ethernet and OTN streams. Advantageously, enabling Ethernet and OTN to carry synchronous information will de-risk switching from SONET/SDH to Ethernet and/or OTN for service providers. The present invention also includes frame decomposition of the Ethernet stream. Ethernet packets are broken into fixed bandwidth and excess bandwidth. The fixed bandwidth is subdivided into fixed (negotiated) flits, with each flit corresponding to a specific user or combination of users like a private tunnel.
