The promise of 40 and 100 gigabit Ethernet in the near future shows that the processing needed for a network protocol is scaling at least as quickly as communication speed. To keep up with this rapid increase in speed, the end nodes have to increase the amount of the packet processing to avoid the bottleneck in the network. Large Sending Offload LSO is a defacto standard, which is offloaded to network interface for sending packets up to 10 Gbps. In this paper, we have provided an appropriate approach that can scale the LSO to high-speed communication line beyond the 10 Gbps. A specialized cost-effective RISC core with low rate power has been designed to execute the new scheme for the LSO to support communication rate up to 100 Gbps. Other devices are; also implemented to support the RISC like the DMA. The processing cycles that the RSIC needed for TCP/IP and UDP/IP has been measured. The RISC’s performance is also presented. A moderate rate with 423 MHz RISC core can support the sending-side processing for up to 100 Gbps transmission speed for the TCP/IP and UDP/IP protocols. A DMA with 2115 MHz is applied in order to reduce the idle cycles of the RISC core. |
