21 Mar 2010TL;DR: A novel statistical approach is presented for ROADM cascade penalty allocation, which reduces OSNR penalty with negligible impact to the worst case penalty estimate.
Abstract: ROADM elements in DWDM optical networks exhibit variations in pass-band amplitude response due to manufacturing variations and supplier diversity. We present a novel statistical approach for ROADM cascade penalty allocation, which reduces OSNR penalty with negligible impact to the worst case penalty estimate.

01 Mar 1999TL;DR: In this article, the authors propose a system and method for automatically generating a topology of a network having synchronous optical network (SONET) switches. But it requires each switch to pass information about itself to other switches in the network so that every switch can maintain a topological of the network.
Abstract: A system and method for automatically generating a topology of a network having synchronous optical network (SONET) switches. Switches in the network pass information about itself to other switches in the network so that every switch can maintain a topology of the network. Using this knowledge of the network topology, each switch can generate a communication route within the network and automatically allot bandwidth for the route. Each switch may generate a new route in response to a line failure.

29 Jul 2014TL;DR: In this article, a ring protection protocol is proposed to provide redundancy in a network node implementing ring protection, where each of the two ring ports connecting the node to other nodes in a ring supporting the protocol may be maintained by a separate line card.
Abstract: Systems and methods are disclosed for providing redundancy in a network node implementing a ring protection protocol. Each of the two ring ports connecting the node to other nodes in a ring supporting the protocol may be maintained by a separate line card. Should one line card fail, traffic passing through the node may be redirected through the remaining ring port under the control of the surviving state machine. The two state machines may be coordinated over the backplane of the node to maintain a common state, making them transparent to other nodes. Additionally, the backplane link between the state machines may be monitored for failures that may be addressed with messages used to respond to general ring failures and by assigning one state machine to block a ring port upon recovery to prevent a loop within the ring until the ring protection link can be blocked.

14 Jul 2008TL;DR: In this article, the authors provide methods and systems for mitigating polarization changes associated with an optical communication signal caused by mechanical disturbances to an optical fiber dispersion compensation module of an optical communications network.
Abstract: The present invention provides methods and systems for mitigating polarization changes associated with an optical communication signal caused by mechanical disturbances to an optical fiber dispersion compensation module of an optical communication network. The methods include disposing a first damping material between an optical fiber and a housing associated with the optical fiber dispersion compensation module; wherein the first damping material is selected and positioned such that it mitigates relatively fast polarization changes. Optionally, the methods also include disposing a second damping material between the optical fiber and the housing associated with the optical fiber dispersion compensation module; wherein the second damping material is selected and positioned such that it mitigates relatively slow polarization changes. Thus, frequency range specific optical fiber dispersion compensation module mechanical perturbation isolation methods and systems are provided.

05 Jun 2007TL;DR: In this paper, a method and apparatus is described which enables location information associated with a client to easily be obtained by a service provider in a packet-based network, where the location information may be the location of the client itself, or may be location associated with devices in a communication facility established by the client.
Abstract: A method and apparatus is described which enables location information associated with a client to easily be obtained by a service provider in a packet-based network. The location information may be the location of the client itself, or may be location information associated with devices in a communication facility established by the client. Location information associated with the client may be provided to services such as emergency services to facilitate fast dispatch of resources to assist the client. Location information associated with facilities of the client may be used to facilitate lawful interception of client communications. In one embodiment, the location information is obtained using information included in one of a Provider Backbone Bridge (PBB) or Provider Backbone Transport (PBT) packet.
