摘要： A “Key-Value Manager” applies an RDMA-based memory allocator to implement a distributed and lock-free B-Tree based key-value store. In various implementations, the Key-Value Manager is implemented as a standalone library running concurrently on large numbers of networked computing devices. The RDMA-based memory allocator of the Key-Value Manager allocates and accesses the memory of the key-value store via various sequences of RDMA messages (e.g., RDMA reads, RDMA writes, and RDMA atomic compare and swap (CAS) operations). As such, CPUs of computing devices hosting the memory of the key-value store do not need to be notified of or involved in RDMA-based reads and writes to that memory. Consequently, CPU utilization for any computing device that hosts any portion of the key-value store is minimal, thereby enabling the Key-Value Manager to scale to very large numbers of concurrent accesses by very large numbers of computing devices.

摘要： Apparatuses, methods and storage medium associated with buffering data in a switch are provided. In embodiments, the switch may include a plurality of queue buffers, a plurality of queues respectively associated with the plurality of queue buffers, a shared buffer, and a queue point controller coupled with the plurality of queue buffers and the shared buffer. In embodiments the queue point controller may be configured to determine an amount of available space in a selected queue buffer of the plurality of queue buffers. The queue point controller may be further configured to allocate at least a portion of the shared buffer to a selected queue that is associated with the selected queue buffer. In embodiments, this allocation may be based on the amount of available space determined in the selected queue buffer. Other embodiments may be described and/or claimed.

摘要： A shared memory is described having a plurality of receive ports and a plurality of transmit ports characterized by a first data rate. A memory includes a plurality of memory banks organized in rows and columns. Operation of the memory array is characterized by a second data rate. Non-blocking receive crossbar circuitry is operable to connect any of the receive ports with any of the memory banks. Non-blocking transmit crossbar circuitry is operable to connect any of the memory banks with any of the transmit ports. Buffering is operable to decouple operation of the receive and transmit ports at the first data rate from operation of the memory array at the second data rate. Scheduling circuitry is operable to control interaction of the ports, crossbar circuitry, and memory array to effect storage and retrieval of the data segments in the shared memory. The scheduling circuitry is further operable to facilitate striping of each data segment of a frame across the memory banks in one of the rows, and to facilitate striping of successive data segments of the frame across successive rows in the array.

摘要： In particular embodiments of the present invention, a method for switching is provided. In particular embodiments, the method includes receiving a packet at an input port of a switch, the packet associated with a virtual local area network identifier (VLAN ID) and a Media Access Control (MAC) address, the switch comprising a forwarding database and a plurality of output ports. The method also includes masking the VLAN ID to create a masked VLAN ID comprising fewer bits than the VLAN ID associated with the packet. The method further includes applying a function to the MAC address and the masked VLAN ID to generate an index, and, at the forwarding database, using the index to identify an output port of the switch. The method also includes transmitting the packet from the identified output port.

摘要： A router (20) for switching a data packet between a source (10) and destination (30) in a network including a plurality of input ports each including a data handler. The data handler divides a data packet into one or more fixed length cells. The router (20) includes a plurality of output ports at least one of which is for routing the data packet to the destination (30) and a memory divided into a plurality of memory banks. An input switch receives fixed length cells from the input ports and writes a single output switch routes cells received from the memory to an appropriate output port.

摘要： In asynchronous optical packet switches, scheduling packets from a buffer randomly will cause less efficient utilisation of the buffer. Additionally, reordering of packets may cause problems for service quality demanding applications. According to the present invention a new electronic buffer scheduling algorithm is proposed and a switch utilizing this algorithm is disclosed. The algorithm is designed for utilizing the buffer resources efficiently, still avoiding serious packet reordering.
