In today's reconfigurable optical add / drop multiplexer (ROADM) based optical node, transponders associated with the ROADMs' add / drop ports are dedicated to a given network node interface. Dedicated transponders reduce the flexibility to route around network failures. Example embodiments of the invention includes an optical node and corresponding method for routing optical signals within an optical node. The optical node may include at least two ROADMs to transmit respective wavelength division multiplexed (WDM) signals onto at least two inter-node network paths and at least one add / drop module including add ports to direct add wavelengths received from tributary network paths to each of the ROADMs via intra-node network paths to allow the wavelengths to be available to be added to the inter-node network paths. Advantageously, a transponder may transmit and receive to and from different network node interfaces within the optical node, thereby improving the optical node's ability to route around network failures.

In today's reconfigurable optical add / drop multiplexer (ROADM) based optical node, ROADMs multiplex (and demultiplex) colored optical signals to form wavelength-division multiplexed (WDM) signals. Transponders connected to the ROADMs' add / drop ports convert noncolored optical signals to colored optical signals (and vice versa). Dedicating transponders to given ports degrades the node's ability to route around network failures. Example embodiments of the invention include an optical node and corresponding method for routing optical signals within an optical node that compensate for this inflexibility. The optical node may include two ROADMs to transmit respective WDM signals onto at least two internode network paths and a routing module that can direct channels of the same wavelength along different internode network paths. Advantageously, a transponder may transmit (receive) different signals at the same wavelength to (from) different network node interfaces within the optical node, thereby improving the optical node's ability to route around network failures.

A method for control an access network node which is comprising of central office (CO) and more than one customer premises equipment (CPE), provides a single management interface in the CO to a software defined network management system, that utilizes a software defined network protocol, the interface allows the software defined network management system to configure an user flow in the access network node by assigning a network node interface resides in the CO which interconnects to a core network and an user network node interface resides in the CPE which interconnects to a user terminal and a required user data forwarding function for the flow, the access network node maintains its own forwarding resources and it determines available resources required for the forwarding request, configures the CO and / or the CPE with a protocol translation which adapts the software defined protocol with the legacy protocol when the CO and / or the CPE works with the legacy protocol.

A virtual access node comprising of a Central Office (CO) and more than one Customer Premises Equipment (CPE), that can be a mixture of a SDN native and a SDN non-native device, supports a virtualized access Network Node Interface (NNI) in the CO and a virtualized access User Network Interface (UNI) in the CPE. A Software Defined Network (SDN) Management System using a SDN control message configures an user data flow in the virtual access node by designating a virtualized access NNI, a virtualized access UNI, and flow forwarding configuration parameters without specifying exact flow forwarding resources. The virtual access node allocates and configures a set of required flow forwarding resources which are distributed in the CO and / or the CPE by that device oriented partitioned control messages with translating in the legacy control message when the resource is in a SDN non-native device.

A method and system for improving call routing in a PNNI network using crankback messaging. A destination logical group node (LGN) blocked crankback procedure is used by entry border nodes, in the event of a failed connection attempt, to instruct preceding routing capable nodes to route the connection over another link. If the entry border node is in the lowest level peer group a Succeeding End Blocked (SEB) crankback message is sent to the preceding routing capable node. If the entry border node is not in the lowest level peer group, a destination LGN blocked crankback message is sent to the preceding routing-capable node wherein the message has special information to signal the routing node that the link into the destination LGN is blocked.
