A first switching device in a switching system that includes a plurality of switching devices arranged in a partial mesh receives a packet directed to a second switching device in the switching system. The first switching device accesses a forwarding table to select a link via which to transmit the packet. The link is selected from among i) at least one destination link coupled to the first switching device, the destination link configured to only carry traffic, egressing the first switching device, that terminates at a next switching device directly coupled to the first switching device, and ii) at least one source link coupled to the first switching device, the source link configured to only carry traffic, egressing the first switching device, that is sourced, in the switching system, by the first switching device. The first switching device transmits the packet, via the selected link, towards the second switching device.

One embodiment is directed to an uplink signal combiner that is configured to receive, via the data network, data packets from the remote antenna units. Each of the data packets includes respective control data and respective user data. The respective control data include data for managing a communication link between a baseband unit and a respective remote antenna unit. The respective user data represents a respective uplink signal received by each of the remote antenna units from one or more mobile stations. The uplink signal combiner is configured to generate additional user data representing a first combined uplink signal by combining the user data extracted from the data packets. The uplink signal combiner is configured to transmit an additional data packet to the baseband unit. The additional data packet includes the additional user data and additional control data derived from the control data from the received data packets.

The application provides a data forwarding and scheduling method and device. The method comprises: obtaining control information to be forwarded and a target output port; when the target output port is not congested and there is no control information sent to the target output port on an LL path, copying the control information to be forwarded to obtain shadow control information; sending the control information to be forwarded to the target output port through the LL path and sending the shadow control information to the target output port through a store-and-forward SAF path; when the last scheduled and output control information is from a SAF path cache queue, scheduling the first control information in the queue head from the SAF path cache queue; when the first control information is the shadow control information, scheduling and outputting the control information in the queue head from an LL path cache queue; and when the first control information is not the shadow control information, outputting the first control information. The application can more accurately adapt to traffic congestion and ensure that the control information is output in a correct order.

The present invention relates to a system (100) and method for sensing and monitoring marine environment. The system (100) comprises the primary components of a buoy (102), at least one gateway (104), at least one data concentrator (106), and a private cloud computing unit (108). Plurality of sensors (110-1,110-2... 110-n) are embedded with the buoy (102) for the acquisition of various physical, chemical and biological data of marine environmental conditions. The invention also relates to method of organizing such buoys (102) and directed towards providing a command, control and communicating through the gateway (104), and cloud computing unit (108) which is coupled with IoTs establishing an effective functioning between plurality of buoys working in conjunction with each other. The invention also relates to providing a method of measuring various parameters in the marine environment relating to seaweed cultivation through the buoy (102).

Techniques are provided for diminishing latency in a DAS fronthaul network configured to convey time-domain transport data, e.g., time-domain digital transport data or time-domain digital data. Other techniques are provided for obtaining higher DAS fronthaul efficiency.

Embodiments of this specification provide a communication method and apparatus based on a relay cluster. The relay cluster includes a load balancing server and at least two relay servers. The communication method includes: receiving a relay request packet sent by a client, where the relay request packet includes a transaction identifier, and the transaction identifier includes a mode field and a routing information field; acquiring routing information of a first relay server of the at least two relay servers based on a value of the mode field and a value of the routing information field in the relay request packet; and sending a relay allocation packet carrying the routing information of the first relay server to the client, so that the client establishes a relay channel based on the routing information of the first relay server.

Processor device comprising: physical layer logic that can be executed to initialize a link, wherein initializing the link includes signaling a variety of link training states, including a reset state, a detection state, a query state, and a configuration state, wherein the physical layer logic is to send a detection supersequence to another device in association with the detection state, wherein the detection supersequence includes a pattern, and the pattern includes an electrical inactive ordered exit set (EIEOS) and a set of six instances of a training sequence for displaying the detection state, wherein the training sequence includes a defined data sequence to be used in the detection state, and each of the six instances of a training sequence includes a respective head.

A home appliance according to an embodiment of the present invention may comprise: a communication interface that communicates with a user terminal and a server; and a processor that receives a network change request including network change information from the user terminal, registers the network change information on the basis of the network change request, transmits a device search list for neighboring home appliances to the user terminal, receives, from the server, a network change command for at least one neighboring device included in the device search list, and transmits a network change request including the network change information to the at least one neighboring home appliance according to the received network change command.
