20090031394 | METHODS AND SYSTEMS FOR INTER-RESOURCE MANAGEMENT SERVICE TYPE DESCRIPTIONS - 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. | 01-29-2009 |
20100183316 | Methods and Systems for Dynamic Equalization Delay Passive Optical Networks - Systems and methods according to these exemplary embodiments provide for methods and systems improving the protocol efficiency in passive optical networks. Additionally, methods and systems for calculating and transmitting an equalization delay change message are described. | 07-22-2010 |
20100189440 | Methods and Systems for Transmitting Data in Scalable Passive Optical Networks - 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. | 07-29-2010 |
20100208747 | OUTPUT DEMULTIPLEXING FOR DYNAMIC BANDWIDTH ALLOCATION IN PASSIVE OPTICAL NETWORKS - 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. | 08-19-2010 |
20100208752 | Methods and Systems for Frame Generation in Communication Networks - 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. | 08-19-2010 |
20100278533 | BIT MASK TO OBTAIN UNIQUE IDENTIFIER - 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. | 11-04-2010 |
20100302079 | METHOD FOR ALIGNING A SERIAL BIT STREAM WITH A PARALLEL OUTPUT - The invention relates to a method and circuit for aligning a serial bit stream with a parallel output. The method comprises latching Q bits from the serial bit stream into a register, locating a position P of a first bit of a start of frame delimiter (SFD) in the register and discarding P-1 bits from the serial bit stream, before the position of the first bit of the SFD, thereby aligning the serial bit stream with the parallel output. The circuit comprises a latch, a fault tolerant analysis logic (FTAL) for locating a position P of a first bit of a start of frame delimiter (SFD) in the register and a shift register for discarding P-1 bits from the serial bit stream, before the position of the first bit of the SFD, thereby aligning the serial bit stream with the parallel output. | 12-02-2010 |
20140233385 | METHODS AND NETWORK NODES FOR TRAFFIC STEERING BASED ON PER-FLOW POLICIES - A method for redirecting a traffic flow in a communication network, in which a first or default service path has been configured for the traffic flow to go through is disclosed. The method comprises: receiving a notification message from a network node, the notification message including a traffic characteristic information of a packet of the traffic flow; creating a set of rules based on the received traffic characteristic information; and sending the set of rules to a plurality of switches in the communication network, the set of rules configuring a second or alternative service path to be used by subsequent packets of this traffic flow. Also, a network node for carrying out this method is provided. | 08-21-2014 |
20140241356 | METHOD AND SYSTEM FOR FLOW TABLE LOOKUP PARALLELIZATION IN A SOFTWARE DEFINED NETWORKING (SDN) SYSTEM - A method implemented in a Software Defined Networking (SDN) network for flow table lookup parallelization is disclosed. The SDN network contains at least a SDN controller and at least a forwarding element and the SDN network utilizes a plurality of flow tables to perform lookup for forwarding traffic. The method starts with determining dependency of flow tables within the forwarding element using a set of dependency determination rules. A dependency graph is then constructed based on determined dependency of flow tables. A dependency degree count for each flow table within the forwarding element is determined based on the dependency graph. Based on the dependency degree count determination for each flow table, a plurality of parallel lookup groups (PLGs) for the forwarding element is formed, where each parallel lookup group contains one or more flow tables having a same dependency degree count. | 08-28-2014 |
