Abstract: A device receives Internet protocol (IP) addresses and metrics associated with network nodes of a network, and stores the IP addresses and the metrics in a route table. The device receives, from a user equipment, a request to connect to the network, and determines a particular network node, of the network nodes, to which to forward a communication session of the user equipment, based on the request and based on the metrics stored in the route table. The device forwards the communication session of the user equipment to the particular network node, and the particular network node enables the user equipment to connect to the network.

Abstract: An example component polishing method includes polishing a component protecting portions of the component during the polishing using a barrier spaced from the component. The barrier is configured to move together with the component during the polishing.

Abstract: A system and method for generating an authentication token which is used by an issuer associated with a integrated circuit card to authenticate a transaction. A personal card reader receives data, including an authentication cryptogram, from the integrated circuit card. The personal card reader uses the data received from the integrated circuit card to select one of at least two default bitmaps stored in a memory portion of the personal card reader. The personal card reader uses the selected default bitmap and the authentication cryptogram to build the authentication token.

Abstract: A communications system provides a dynamic setting of optimal buffer sizes in IP networks. A method for dynamically adjusting buffer capacities of a router may include steps of monitoring a number of incoming packets to the router, determining a packet arrival rate, and determining the buffer capacities based at least partially on the packet arrival rate. Router buffers are controlled to exhibit the determined buffer capacities, e.g. during writing packets into and reading packets from each of the buffers as part of a packet routing performed by the router. In the disclosed examples, buffer size may be based on the mean arrival rate and one or more of mean packet size and mean waiting time.

Abstract: A device receives Long Term Evolution (LTE) architecture information, Internet protocol (IP) network architecture information, and transport network information, and determines traffic patterns of a LTE network based on the LTE architecture information. The device also generates proposed LTE metropolitan optical transport networks (OTNs) based on the determined traffic patterns and one or more of the LTE architecture information, the IP network architecture information, and the transport network information. The device further determines transit switching for the proposed LTE metropolitan OTNs, and selects, from the proposed LTE metropolitan OTNs, a metropolitan OTN optimized for the LTE network.

Abstract: A network device may handle packet congestion in a network. In one implementation, the network device may receive a packet associated with a quality of service priority class and with a connection to a user device. The network device may include an output queue associated with the priority class of the packet. The output queue may be congested. The network device may determine whether the connection associated with the packet is a guaranteed bit rate connection. The network device may queue the packet according to a first action policy function when the connection associated with the packet is a guaranteed bit rate connection and may queue the packet according to a second action policy function when the connection associated with the packet is not a guaranteed bit rate connection.

Abstract: A network device establishes first and second Ethernet link aggregation groups (LAGs) at a first access site of an optical transport network (OTN), and creates a first optical channel (OCh) LAG subpath from the first Ethernet LAG, via a second access site of the OTN, to an Ethernet LAG at a third access site of the OTN. The network device also creates a second OCh LAG subpath from the first Ethernet LAG, via a distribution site of the OTN, to the Ethernet LAG at the third access site, and creates a first optical data unit (ODUk) LAG subpath from the second Ethernet LAG to an Ethernet LAG at the second access site. The network device further creates a second ODUk LAG subpath from the second Ethernet LAG, via the distribution site and the third access site, to the Ethernet LAG at the second access site.

Abstract: A communications system provides a dynamic setting of optimal buffer sizes in IP networks. A method for dynamically adjusting buffer capacities of a router may include steps of monitoring a number of incoming packets to the router, determining a packet arrival rate, and determining the buffer capacities based at least partially on the packet arrival rate. Router buffers are controlled to exhibit the determined buffer capacities, e.g. during writing packets into and reading packets from each of the buffers as part of a packet routing performed by the router. In the disclosed examples, buffer size may be based on the mean arrival rate and one or more of mean packet size and mean waiting time.

Abstract: A temperature and humidity controlled building houses sensitive telecommunications equipment in operation. A secure outdoor shelter within a closed perimeter abutting the building utilizes the exterior of one wall of the building as a portion of its perimeter. The outdoor shelter contains outdoor-hardened telecommunications equipment, also in operation, which dissipates large quantities of heat to the atmosphere. There are coax cable and waveguide operative interconnections between the sensitive telecommunications equipment and the outdoor-hardened telecommunications equipment, the interconnection being made through the one wall without affecting control of the temperature and humidity in the building. There is a further coax cable and waveguide connection from the outdoor equipment to a cell tower where wireless transmission takes place. The outdoor shelter can be expanded modularly.

Abstract: An approach is provided for facilitating supply chain management based on point-of-sales or device usage data regarding a user device. A supply chain management platform receives an activation signal indicating activation of a device. The supply chain management platform then determines device information relating to the device based on the activation signal. Device information is then stored and subsequently analyzed to generate supply chain management information relating to production of the device.
