Abstract: Communication apparatus includes a host interface for connection, via a host bus, to a host processor and a host memory, which is mapped to an address space of the host bus, and a network interface, configured to transmit and receive packets over a network. A local memory is configured to hold data in a memory space that is not mapped to the address space of the host bus. Packet processing circuitry, which is connected between the host interface and the network interface and is connected to the local memory, is configured to receive from the network interface a packet carrying a remote direct memory access (RDMA) request that is directed to an address in the local memory, and to service the RDMA request by accessing the data in the local memory.

Abstract translation: 通信装置包括主机接口，用于经由主机总线连接到被映射到主机总线的地址空间的主机处理器和主机存储器，以及被配置为经由网络发送和接收分组的网络接口。 本地存储器被配置为将数据保存在未映射到主机总线的地址空间的存储器空间中。 连接在主机接口和网络接口之间并连接到本地存储器的分组处理电路被配置为从网络接口接收携带指向地址的远程直接存储器访问（RDMA）请求的分组 本地内存，并通过访问本地内存中的数据来服务RDMA请求。
