20160072607 | METHOD AND APPARATUS FOR RECONFIGURING WAVELENGTH OF OPTICAL NETWORK UNIT - The invention provides a method and apparatus for reconfiguring wavelength of the ONU. To be specific, the OLT sends a Deactivate_ONU-ID message to the ONU, the Deactivate_ONU-ID message including a reconfiguration flag, a new receive wavelength assigned for the ONU and a new transmit wavelength assigned for the ONU. After receiving the Deactivate_ONU-ID message from the OLT, the ONU discards the TC layer parameters related to the current wavelength channel, and determines whether the reconfiguration flag included in the Deactivate_ONU-ID message indicates the receive wavelength and the transmit wavelength of the ONU are required to be reconfigured. If so, then the ONU replaces its original receive wavelength and original transmit wavelength with its new receive wavelength and the new transmit wavelength included in the Deactivate_ONU-ID message, and enters initial state; and if not, then the ONU enters initial state directly. | 2016-03-10 |

For example, a flow allocation has, for each of a plurality of different types of physical resources of the datacenter used by the flow, an amount of the physical resource that the flow can use. A flow is a path between endpoints of the datacenter along which messages are sent to implement a service. In examples, the flow allocations are sent to enforcers in the datacenter, which use the flow allocations to control the rate of traffic in the flows. | 2016-03-10 |
20160072705 | METHOD AND DEVICE FOR PROCESSING ADDRESS RESOLUTION PROTOCOL IN SOFTWARE-DEFINED NETWORKING ENVIRONMENT - A method and device for processing an address resolution protocol (ARP) in a software-defined networking (SDN) environment is disclosed. The method includes receiving, by a first network device, an ARP request packet from a first terminal so that the first terminal communicates with a second terminal and transmitting, by the first network device, an ARP response message including MAC address information of the second terminal to the first terminal as a response to the ARP request packet. Accordingly, a load of the controller can be reduced by sharing and processing an ARP proxy function with the network device in the SDN environment. | 2016-03-10 |
20160072706 | Adaptive Private Network with Dynamic Conduit Process - Systems and techniques, including special messages and state machines, are described that configures an intermediate site to dynamically trigger creation of and removal of a dynamic conduit between two sites based on usage that is tracked at the sites. The intermediate site providing WAN-to-WAN forwarding between the two sites, monitors throughput statistics on each local WAN link (LWL) associated with the two sites. If traffic between the two sites passes a configured first threshold or if LWL usage passes a configured second threshold, the intermediate site sends a message to the two sites to set up a dynamic conduit directly coupling the two sites. Busy lists are used to keep track of eligible site pairs. Once a dynamic conduit is set up between two sites, a grow technique tests the dynamic conduit increasing communication flows between the two sites each configured sampling period before putting the conduit in normal use. | 2016-03-10 |
20160072707 | METHOD FOR TRANSMITTING INFORMATION AND DEVICE FOR CARRYING OUT THE METHOD - An electric motor and a motor control unit exchange information using at least one transfer signal, the information including motion state information of the electric motor and additional information transmitted via a transmission channel, where the motion state information is in the form of at least one base signal and the additional information is transmitted with the aid of the base signal. | 2016-03-10 |
