It enables the linking of networks using signaling, Internet Protocol (IP) or Asynchronous Transfer Mode (ATM) networks. A network-to-network interface is also known as a network node interface (NNI).

Methods and apparatus for performing directionless wavelength addition and subtraction within a ROADM based optical node

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.

Methods and apparatus for performing directionless and contentionless wavelength addition and subtraction

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.

Linear protection switching method applicable to large-capacity PTN (packet transport network) device

The invention relates to a linear protection switching method applicable to a large-capacity PTN (packet transport network) device. At a communication source end node, output ports are configured by a crossed unit into three service forwarding instances, namely a main NNI (network node interface) port, a standby NNI port, and a main-standby NNI port; keywords matched to generate target MAC (media access control) addresses, namely MACn1, MACn2, and MACn3; at a communication destination end node, the interface units of the main and standby NNI interfaces are respectively configured with service processing instances; and the keyword to be matched is a Tunnel label; however, only the main service instance is in activated state; during switching, corresponding switching operations are implemented according to protection modes (1-plus-1 protection and 1-to-1 protection). The most fundamental thought of the linear protection switching method applicable to the large-capacity PTN (packet transport network) device is to convert centralized switching into distributed switching; the crossed unit only implements high speed packet forwarding, and does not participate in switching motions; therefore, the switching motions are carried out by a plurality of service processing units; moreover, the service processing units process the switching motions concurrently, so the switching speed is improved by times.
