Abstract: Disclosed is an integrated radio network that can host a plurality of network operators, each of which may be transmitting and receiving packetized signals over a fronthaul network. Each of the network operators may have one or more prioritized packet streams whereby a given network operator may have a plurality of prioritized packet streams having a different allocated priority, and the plurality of network operators may have a differentiated priority among each other. The integrated radio network has a switch/monitor that (1) identifies one or more network operators exceeding their respective allocations and mitigates the violation; and (2) identifies fronthaul network bottlenecks and takes action to mitigate the bottleneck by reducing or impeding low priority packet streams.

Abstract: The technology disclosed provides a method of testing handling of HTTPS sessions of a plurality of clients with a plurality of servers by a switching, bridging or routing device (i.e., a DUT), where the testing is conducted by a test system coupled to ports on the DUT. The method includes using client state machines running on at least four processor cores, communicating through the DUT with server state machines running on at least four additional processor cores. The method also includes, for each connection between a client represented by a client state machine and a server represented by a server state machine, setting up an HTTPS session by negotiating an encryption protocol and completing an HTTPS handshake. Further, the method includes following the setup of between 100,000 HTTPS sessions and 10,000,000 HTTPS sessions, conducting a stress test including combining payload data and header information without using the negotiated encryption.

Abstract: Systems and methods for facilitating movement of a patient transport apparatus. The patient transport apparatus has a support structure and a patient support surface. Caster assemblies are coupled to the support structure to roll about a roll axis and swivel about a swivel axis. A control system is configured to control brake mechanisms, steer-lock mechanisms, and pre-swivel mechanisms of the caster assemblies based on one or more inputs.

Abstract: A unique method/device for isolating the over-the-air segment within a mobile communications network is provided. A coordinated set of tests is run to isolate problems in an end-to-end network including over-the-air segment, wired, and core network segments. Test results are compared to identify which segment or components within a segment is failing. The testing device executes the same test in two differentiated modes. In one mode, the device acts as a mobile client device identified by subscriber identification data that communicates with the network base station over-the-air using the standard control and data protocols of the mobile network. In another mode, the testing device, identified by the same subscriber identification data, acts like the combination of the same Mobile Client Device(s) and a Network Base Station using a wired interface that is equivalent to the wired interface that connects the network base station to the rest of the wired network.

Abstract: Systems and methods to assist wireless telecom service providers to determine the optimal core network evolution plan in a network planning time period. Total cost of ownership of wireless core networks is generally modeled to include capital expenditure, customer acquisition and retention cost, network operational cost and staffing and engineering cost. The total cost of ownership model is used to determine the optimal core network evolution plan at different layers of the core networks, which are modeled as a number of abstract networks in mathematical terms. A core network evolution optimization algorithm determines the optimal number of core network configurations and when to deploy the configurations in the planning period in order to minimize the total cost of ownership. A multi-level serving area optimization algorithm determines an optimal core network configuration at a given point of time.
