  • BIT MASK TO OBTAIN UNIQUE IDENTIFIER
    Publication number: 20100278533
    Abstract: Methods and communication nodes for assigning unique identifiers to a plurality of nodes. A plurality of data values are maintained in memory, each being associated to one of the nodes. A bit mask value is obtained that, when applied to the plurality of data values, produces a plurality of unique identifiers. The bit mask value is made available to the nodes thereby assigning a unique identifier to each of the nodes.

  • Methods and Systems for Frame Generation in Communication Networks
    Publication number: 20100208752
    Abstract: Exemplary embodiments provide for methods and systems that enable frame generation by fields taken from various queues. Protocol control can also or alternatively be distributed so that one or more header fields can be generated separately from other portions of a frame, e.g., the payload. The one or more header fields can be entered into queues from which they are taken to generate frames.

  • OUTPUT DEMULTIPLEXING FOR DYNAMIC BANDWIDTH ALLOCATION IN PASSIVE OPTICAL NETWORKS
    Publication number: 20100208747
    Abstract: Systems and methods according to these exemplary embodiments provide for mechanisms and methods that allow for improving the efficiency of a passive optical network (PON). Upstream data transmission can occur by allowing an optical network unit (ONU) cycle to overlap more than one GPON transmission convergence (GTC) frame. Additionally, or alternatively, multiple different bandwidth maps can be transmitted per dynamic bandwidth allocation (DBA) cycle to inform ONUs of their respective, upstream bandwidth allocations.

  • Methods and Systems for Transmitting Data in Scalable Passive Optical Networks
    Publication number: 20100189440
    Abstract: Systems and methods according to these exemplary embodiments provide for methods and systems that enable decoupling of medium access control (MAC) functions from other optical transceiver functions to, for example, promote scalability of passive optical networks (PONs). A MAC frame processing unit can communicate MAC frames to optical transceiver modules via an interconnect using an encapsulating frame according to another communications protocol, e.g., XAUI.

  • METHODS AND SYSTEMS FOR INTER-RESOURCE MANAGEMENT SERVICE TYPE DESCRIPTIONS
    Publication number: 20090031394
    Abstract: Communication nodes, systems and methods are described which provide access screening for services based upon service type description information and policy criteria information associated with an access network. If a requested service is, e.g., banned due to regulatory policies in a geographic region associated with a particular access network, then the requested service shall be denied even if the user has a valid subscription to such requested service via another access network.
