BCM5706 provides fully integrated Layer Layer solution TCP/IP, RDMA iSCSI 1.0/iSER along with complete 10/100/ 1000BASE-T Gigabit Ethernet, IEEE 802.3 compliant Media Access Control (MAC) Physical Layer Transceiver solution high performance network applications. itself BCM5706 provides complete single-chip Gigabit Ethernet with TCP/IP Offload Engine, RDMA (RNIC), iSCSI 1.0/iSER solution. BCM5706 different from other network controllers because process TCP/IP relevant protocols data directly from application buffers host, therefore relieving host from these time-consuming operations. receive path, BCM5706 processes frame highest layer supported present e.g., BCM5706 processes frame RDMA when frame RDMA frame. With appropriate configuration, BCM5706 simultaneously support following three functions: RDMA Network Interface Controller (RNIC) iSCSI iSER Host Adapter Chimney enabled network accelerator
