An antenna control system in a base station system, and a configuration method of the antenna control system are disclosed. A method of controlling antennas in a multi-ALD (Antenna Line Device) system including ALDs and ports linked with multiple base stations is provided including receiving configuration command by one of ALDs from one of base stations, transferring configuration command by the ALD that received configuration command to each of remaining ALDs, and setting an antenna for controlling or port for linking by each ALD according to the configuration command. In accordance with some embodiments, a multi-ALD system for controlling a plurality of antennas includes ports for linking with multiple base stations, respectively, and ALDs for controlling the antennas, wherein the ALDs are linked for intercommunications with each other, to set an antenna to control or a port to link according to configuration command received from one of the base stations.

A digital data communications network that supports efficient, scalable routing of data and use of network resources by combining a recursive division of the network into hierarchical sub-networks with repeating parameterized general purpose link communication protocols and an addressing methodology that reflects the physical structure of the underlying network hardware. The sub-division of the network enhances security by reducing the amount of the network visible to an attack and by insulating the network hardware itself from attack. The fixed bandwidth range at each sub-network level allows quality of service to be assured and controlled. The routing of data is aided by a topological addressing scheme that allows data packets to be forwarded towards their destination based on only local knowledge of the network structure, with automatic support for mobility and multicasting. The repeating structures in the network greatly simplify network management and reduce the effort to engineer new network capabilities.

Datalink frames or networking packets contain protocol information in the header and optionally in the trailer of a frame or a packet. We are proposing a method in which part of or all of the protocol information corresponding to a frame or a packet is transmitted separately in another datalink frame. The “Separately Transmitted Protocol Information” is referred to as STPI. The STPI contains enough protocol information to identify the next hop node or port. STPI can be used avoid network congestion and improve link efficiency. Preferably, there will be one datalink frame or network packet corresponding to each STPI, containing the data and the rest of the protocol information and this frame/packet is referred to as DFoNP. The creation of STPI and DFoNP is done by the originator of the frame or packet such as an operating system.

A data processing system arranged for receiving over a network, according to a data transfer protocol, data directed to any of a plurality of destination identities, the data processing system comprising: data storage for storing data received over the network; and a first processing arrangement for performing processing in accordance with the data transfer protocol on received data in the data storage, for making the received data available to respective destination identities; and a response former arranged for: receiving a message requesting a response indicating the availability of received data to each of a group of destination identities; and forming such a response; wherein the system is arranged to, in dependence on receiving the said message.

A front adapter for connecting to a control device, has a connection device connected to a predetermined system cable for connecting at least one field component, at least one wireless communication interface for wirelessly transmitting and receiving signals to or from at least one wireless one transmitting and/or receiving device which can be connected to a first field unit, and/or at least one bus-capable communication interface for transmitting and receiving signals via a signal bus to or from at least one bus-capable transmitting and/or receiving device which can be connected to a second field device, and a control and/or evaluation device which is adapted to control the transmitting of signals between the control device and the at least one wireless transmitting and/or receiving device and/or the at least one bus-capable transmitting and/or receiving device.

A user-mode protocol stack-based network isolation method includes: at a bottom-layer network card interface of a user-mode protocol stack, for each network card, adding an isolation space pointer for binding to a network isolation space; when a service application is initialized, configuring a plurality of user-mode protocol stack network isolation spaces with independent protocol stack private tables based on the user-mode protocol stack; for each network card, designating a corresponding user-mode protocol stack network isolation space through the isolation space pointer of each network card; and for service data received from each network card, performing data processing on the service data through protocol stack private tables in a user-mode protocol stack network isolation space corresponding to the network card.

In some embodiments, a method receives a packet for a flow associated with a workload. Based on an indicator for the flow, the method determines whether the flow corresponds to one of an elephant flow or a mice flow. Only when the flow is determined to correspond to an elephant flow, the method enables a hardware acceleration operation on the packet. The hardware acceleration operation may include hardware operation offload, receive side scaling, and workload migration.

A first fabric abstraction layer couples to a data link layer and a physical layer of a network fabric device. The network fabric device is connected to other network elements within a network via at least one network connection, such as a fiber optic connection. A second fabric abstraction layer couples to the data link layer and an application of the network device. The second fabric abstraction layer provides an application programming interface (API) to the application. The API allows the application to generate configuration instructions for configuring the at least one network connection. Upon receiving the configuration instructions generated by the application, the second abstraction layer sends the configuration instructions to the first abstraction layer via the data link layer. The first abstraction layer then configures the at least one network connection to transmit data according to the configuration instructions.
