A communication device includes a first client group in a first region; a second client group in a second region different from the first region; a first data hub configured to generate first burst data and a first control packet based on first client data received from the first client group; a second data hub configured to generate second burst data and a second control packet based on second client data received from the second client group; and a data transfer unit connected to the first data hub and the second data hub via a control protocol, the data transfer unit configured to, store the first burst data in a target memory based on the first control packet, and store the second burst data in the target memory based on the second control packet.

A streaming platform reader includes: a plurality of reader threads configured to retrieve messages from a plurality of partitions of a streaming platform, wherein each message in the plurality of partitions is associated with a unique identifier; a plurality of queues coupled to the plurality of reader threads configured to store messages or an end of partition signal from the reader threads, wherein each queue includes a first position that stores the earliest message stored by a queue; a writer thread controlled by gate control logic that: compares the identifiers of all of the messages in the first positions of the queues of the plurality of queues, and forwards, to a memory, the message associated with the earliest identifier; and wherein the gate control logic blocks the writer thread unless each of the queues contains a message or an end of partition signal.

A method includes transmitting a first write request that includes a first encoded data slice of a first data object encoded under a first encoding scheme, and a first slice identifier corresponding to the first encoded data slice assigned to a first memory location of a distributed storage network (DSN) based on the first slice identifier. A second write request that includes a second encoded data slice of the first data object encoded under a second encoding scheme, and a second slice identifier corresponding to the second encoded data slice, is transmitted, and the second encoded data slice is assigned to a second memory location of the DSN based on the second slice identifier. A request to access the first data object is received. A derived second slice identifier is generated in response to determining that the first data object requested for access is stored under multiple encoding schemes.

A radio receiving apparatus for receiving the variable-length RLC PDU data in an RLC layer includes the buffer memory sectioned into a plurality of areas having a predetermined maximum data length of the RLC PDU data. By referring to a sequence number SN included in each received RLC PDU data, the radio receiving apparatus stores the RLC PDU data having an identical sequence number SN into an identical area, and assembles an RLC SDU data on a basis of the RLC PDU data stored in each area.

A traffic manager is shared amongst two or more egress blocks of a network device, thereby allowing traffic management resources to be shared between the egress blocks. Schedulers within a traffic manager may generate and queue read instructions for reading buffered portions of data units that are ready to be sent to the egress blocks. The traffic manager may be configured to select a read instruction for a given buffer bank from the read instruction queues based on a scoring mechanism or other selection logic. To avoid sending too much data to an egress block during a given time slot, once a data unit portion has been read from the buffer, it may be temporarily stored in a shallow read data cache. Alternatively, a single, non-bank specific controller may determine all of the read instructions and write operations that should be executed in a given time slot.

The present invention provides a method for accessing a system memory, wherein the method includes the steps of: reading a descriptor from the system memory, where the descriptor includes a buffer start address field and a buffer size field, wherein the buffer start address field includes a start address of a buffer in the system memory, and the buffer size field indicates a size of the buffer; receiving multiple packets, and writing the multiple packets in to the buffer; modifying the descriptor according to the multiple packets stored in the buffer to generate a modified descriptor, wherein the modified descriptor only comprises information of part of the multiple packets or does not comprise information of any one of the multiple packets; and writing the modified descriptor into the system memory.

A system for communicating a multi-destination packet through a network switch fabric is described. The system receives the multi-destination packet at an input port of the network switch fabric, wherein the multi-destination packet is directed to multiple output ports, and wherein the network switch fabric has a virtual output queue (VOQ) architecture, wherein each input port maintains a separate VOQ for each output port. The system sends the multi-destination packet by inserting the multi-destination packet into VOQs associated with the multiple output ports. While inserting the multi-destination packet in each VOQ, if the VOQ is empty, the system inserts the multi-destination packet at a head of the VOQ. Otherwise, if the VOQ is not empty and if the VOQ contains an end of a last complete packet received by the VOQ, the system inserts the multi-destination packet into the VOQ at the end of the last complete packet.
