20140133844 | SEQUENCE-BASED LINK FAULT LOCALIZATION - Methods and apparatus for a network element or server end station to determine an estimated physical location of a fault in a communications link utilized by two network elements. In an embodiment, the first and second network elements generate link failure indications including time values representing when the respective network element detected the fault. In other embodiments, the link failure indications include time values transmitted over the communications link between the first and second network elements. A time distance between these time values is calculated, which is used to calculate the estimated physical location of the fault. In some embodiments, the link failure indications include sequence numbers transmitted or about to be transmitted over the communications link between the network elements. Sequence distances are calculated between the sequence numbers, and are used to calculate the estimated physical location of the fault. | 05-15-2014 |

20140186037 | OPTICAL PORT DISCOVERY IN A WDM OPTICAL NETWORK - A hub node in a wavelength division multiplexed optical network automatically discovers at least one of new client-side optical ports and new edge-side optical ports. The hub node comprises a wavelength switch network, port discovery equipment, and a controller. The wavelength switch network routes any wavelength channel that does not support a matching pair of client-side and edge-side ports to port discovery equipment at the hub node. The port discovery equipment searches for new ports, and, responsive to finding a new port, automatically discovers a predefined set of one or more attributes of the new port. The controller determines that a client-side port and an edge-side port are a matching pair of ports if discovered sets of attributes of those ports match according to one or more predefined rules. The controller then controls the wavelength switch network to re-route the wavelength channel supporting that matching pair between those ports. | 07-03-2014 |
20140348074 | METHOD AND APPARATUS FOR CONTROLLING A SIGNAL PATH OF A RADIO COMMUNICATION - A method and a remote digital unit in a central office of a core network, for handling a radio communication for a mobile terminal being connected to an access point at a local site. The remote digital unit determines that the mobile terminal can be served locally by a local digital unit connected to a local signal switching unit at the local site, and instructs the local digital unit to locally process signals to or from the mobile terminal in the communication. The remote digital unit further schedules the signals over a radio interface between the mobile terminal and the access point, and sends updated scheduling information to the local digital unit to indicate the scheduling, thereby enabling the local digital unit to handle the radio communication according to the updated scheduling information. In this way, the functionality of a base station is divided into a relatively simple digital unit and switching function at the local site and a more advanced digital unit with scheduling function at the central office, such that the costs for implementing radio access at a local site are low and tromboning of communicated signals over the core network can be avoided. | 11-27-2014 |
20140376920 | NETWORK NODE AND A METHOD THEREIN ENABLING A FIRST UNIT TO CONNECT OR TO BE CONNECTED AD-HOC TO A SECOND UNIT - Embodiments herein relate to a method in a network node configured in an optical network for enabling a first unit to connect ad-hoc to a second unit in a system configured for remote radio units and main units. The network node receives a connection request from the first unit over the optical network. The network node establishes a connection, to the first unit, for retrieving control data. The network node stores control data regarding the first unit. The control data is retrieved from the first unit over the established connection and wherein the control data enables the first unit to connect/be connected ad-hoc to the second unit for transferring user data over a physical path through the optical network. | 12-25-2014 |
