20120250492 | SYSTEMS AND METHODS FOR MOVING DSL LAUNCH POINTS - A system for scaling vectored DSLAM deployments has a DSLAM interfaced with a cross-connect apparatus. The DSLAM receives POTS signals from at least one bridge connection assembly. When a DSLAM is added at the cross-connect facility, at least one connector of the bridge connection assembly is disconnected from an existing DSLAM and is interfaced with the newly-added DSLAM. By moving the connector to the newly-added DSLAM, a batch of downstream distribution pairs (which are preferably bound by a single distribution cable) are effectively moved from the existing DSLAM to the new DSLAM without having to reconfigure the jumpers of the cross-connect apparatus. Accordingly, it is possible to scale the cross-connect facility to any number of vectored DSLAMs while limiting vector group sizes, thereby reducing the complexity of vectoring operations, without having to perform complex reconfigurations of the cross-connect apparatus. | 2012-10-04 |

Ranking mechanism facilitates in determining the “quality” of wireless channels, and the Acknowledgement mechanism facilitates in coordination of the transmissions in the system. The nodes exchange information on the queues status, and decision is made by a scheduling controller on the priority of transmission. | 2012-10-04 |
20120250495 | METHOD OF REDUCING RETRANSMISSION OF DATA FRAME AND RECEIVING NODE THEREFOR - A method of reducing a retransmission of a data frame and a receiving node therefor continuously receiving N data frames generated by encoding K source data packets by erasure coding. Errors in the received N data frames are checked, and an ACK message transmitted informing that the source data packets are capable of being restored, when the number (R) of data frames not containing errors is equal to or greater than the number (K) of source data packets. An ACK message including the number (X) of data frames for which retransmission is to be requested is transmitted when the number (R) of data frames not containing errors is less than the number (K) of source data packets, as a result of checking for errors in the received N data frames. Despite errors in some of the data frames, data may be restored without requesting the retransmission of data frames. | 2012-10-04 |

20120250519 | UNADDRESSED DEVICE COMMUNICATION FROM WITHIN AN MPLS NETWORK - An unaddressed device installed inline in a path of an MPLS network can communicate a packet from within the MPLS network to an upstream device without knowledge of the necessary MPLS labeling by sending the packet intentionally in the wrong direction: downstream. To communicate to an upstream device, the unaddressed device sends a packet downstream into the MPLS network on the opposite side and through the opposite outgoing port from that which would be used for a packet sent to the same device in a non-MPLS network. This behavior forces the MPLS network, when it next inspects the packet, to re-label it with the correct labeling to route the packet on a path back upstream to the recipient device. In this manner, the MPLS architecture is used to redirect or loop back packets from an unaddressed inline device to the upstream device. | 2012-10-04 |

Finding the hubs is performed in the preprocessing stage, and finding the intersecting hubs (i.e., the common hubs they share) is performed in the query stage. During preprocessing, a forward label and a reverse label are defined for each vertex. The labels are generated using contraction hierarchies that may be guided by shortest path covers, and may be pruned. A query is processed using the labels to determine the shortest path. | 2012-10-04 |
