  • Demultiplexing high-order to low-order ODU signals in an optical transport network
    Patent number: 9288006
    Abstract: A method and apparatus are provided for de-multiplexing one or more Low-Order ODUj/ODUflex clients from a High-Order ODUk carrier. The number of TribSlots assigned to an ODUflex may be increased and decreased hitlessly, in accordance to ITU-T G.7044. In the Multiplexing direction, a Space-Time-Space switch is used to interleave bytes from Low-Order ODUk words into High-Order ODUk words. In the De-multiplexing direction, a similar switch is used to extract Low-Order ODUj bytes that are interleaved inside High-Order ODUk words and re-arrange them into Low-Order ODUj words.

  • Multiplexing low-order to high-order ODU signals in an optical transport network
    Patent number: 9025594
    Abstract: A method and apparatus are provided for multiplexing one or more Low-Order (LO) ODUj/ODUflex clients into a High-Order (HO) ODUk in an Optical Transport Network (OTN). LO bytes are multiplexed in accordance with a tributary slot assignment for a selected LO ODUj of the HO ODUk stream using a permutation matrix. In an implementation, each byte on each ingress port of a W-port space-time-space switch is configurably assigned to an associated timeslot of an associated egress port, using time-division multiplexing. The number of TribSlots assigned to an ODUflex may be increased and decreased hitlessly. A Clos-like Space-Time-Space switch is used to interleave bytes from Low-Order ODUk words into High-Order ODUk words.

  • Justification insertion and removal in generic mapping procedure in an optical transport network
    Patent number: 8989222
    Abstract: A method and apparatus are provided for generating Generic Mapping Procedure (GMP) stuff/data decisions, which avoids brute force modulo arithmetic and is efficient for hitless adjustment of ODUFIex (G.7044) in an Optical Transport Network (OTN). Addition operations are used, rather than multiplication operations, to facilitate faster and less computationally expensive calculation of data/stuff decisions, based on calculated residue values. Residue values are logically arranged in rows to facilitate residue calculation, such as based on relationships with previously calculated residue values. This method is also applicable for mapping and de-mapping Constant Bit Rate (CBR) clients into and from an ODUk carrier.

  • Monitoring network traffic
    Publication number: 20050249122
    Abstract: A method for monitoring a wireless network includes, at a device including a communication interface coupling the device to a wireless network, monitoring messages transmitted between the communication interface and the wireless network, and outputting monitoring data associated with the monitored messages from the device.
