Disclosed herein are methods and systems for routing traffic. One exemplary system includes a muxponder module deployed in an optical network, the muxponder having an optical receiver, a first and second electrical port, a demultiplexer having a built-in digital cross-connect, and a processor accessing a first calculated carrier frequency to assign traffic streams associated with a first service identification code to a first and second host lane of the first electrical port, and a second calculated carrier frequency to assign traffic streams associated with a second service identification code to a third and fourth host lane of the second electrical port, and having logic to control the digital cross-connect to route a first and a second traffic stream to the first electrical port based on the first service identification code, and a third and a fourth traffic stream to the second electrical port based on the second service identification code.

Systems and methods for enabling point-to-multi-point applications in common management interface specification

A method and system is described. A signal indicative of a failure of a first channel within a plurality of channels of a transmission signal traversing a signal working path in a network is received. The signal working path has a headend node, a tail-end node and an intermediate node. The first channel has a frequency band and a power level prior to failing. The signal working path is associated with a protection path. The protection path includes the intermediate node, optical cross-connects, and a transmitter supplying (ASE) light. The transmitter is activated to supply the ASE light within a frequency band and having a power level corresponding to the frequency band and power level associated with the first channel. The ASE light is supplied to a cross-connect, such that the cross-connect provides a transmission signal including the ASE light.

Framework for handling signal integrity using ASE in optical networks

An example system includes a transceiver and a microcontroller. The microcontroller is configured to receive, from first and second network interfaces of the transceiver, a plurality of messages from a hub node and the leaf nodes. Each of the messages corresponds to a respective one of the ingress or egress data flows. The microcontroller is also configured generate a resource assignment map based on the messages. The resource assignment map includes pairings between a respective one of the ingress data flows and a respective one of the egress data flows, and, for each of the pairings, an indication of a respective network resource assigned to exchange the egress data flow of that pairing with a respective one of the leaf nodes. The microcontroller is also configured to generate a command to cause the transceiver to transmit the egress data flows in accordance with the resource assignment map.

Correcting traffic misconnections in optical communications networks

Systems, devices, and techniques relating to optical communications are described. A described hub optical module includes an optical transceiver configured to communicate with edge optical modules of respective edge devices via an optical communication network, the edge optical modules comprising edge interfaces; and a controller coupled with the optical transceiver. The controller can be configured to provide, to a hub device, hub interfaces which are configurable to respectively correspond to different optical subcarriers transmitted from and received by the optical transceiver. The controller can advertise, to the hub device, an application select code to enable the hub device to configure an operational mode and to selectively enable each of the hub interfaces in the operational mode, store one or more associations among the hub interfaces and the edge interfaces, and configure one or more cross-connections among the hub interfaces and the optical subcarriers based on the one or more associations.

Optical modules with virtual transport functions

An example system includes a transceiver and a microcontroller. The microcontroller is configured to receive first messages from a hub node via first network interfaces of the transceiver, and determine first logical identifiers associated with ingress data flows. Further, the microcontroller is configured to receive second messages from leaf nodes via second network interfaces of the transceiver, and determine second logical identifies associated with egress data flows. Further, the microcontroller is configured to generate a resource assignment map based on the first and logical identifiers, and to generate a command to cause the transceiver to transmit the egress data flows in accordance with the resource assignment map. The resource map indicates pairings between the ingress data flows and the egress data flows, and, for each of the pairings, a respective network resource assigned to transmit the egress data flow of the pairing to a respective one of the leaf nodes.

A centralized network administrator may automatically provision an Ethernet circuit between network elements by storing and managing circuit data (managed objects) in one of the network elements (master node) and synchronizing the circuit data among the network nodes in the Ethernet circuit path. In addition, multiple network administrators may provision multiple Ethernet circuits using the overlapping network elements by managing access to the circuit data in the Master node.
