In this video from the 2018 OpenFabrics Workshop, Harold Cook from Lightfleet Corporation presents: A New Approach to Switching Network Implementation. "Today’s switched fabrics are inherently inefficient, requiring significant software overhead to route data through the fabric to its intended destination. One of the unintended consequences of this inefficiency and excessive overhead in high load situations is lost packets, which compounds the latency and throughput issues. Other concerns in these software oriented switches are security of the data and “hackability” of the underlying protocols. This presentation provides details of a radically new approach to network technology. By eliminating the switching software altogether, this new approach overcomes the inefficiency and overhead within switched networks. Instead, routing is accomplished in hardware with a highly efficient protocol. An additional feature of this new technology is support …...more

In this video from the 2018 OpenFabrics Workshop, Harold Cook from Lightfleet Corporation presents: A New Approach to Switching Network Implementation. "Today’s switched fabrics are inherently inefficient, requiring significant software overhead to route data through the fabric to its intended destination. One of the unintended consequences of this inefficiency and excessive overhead in high load situations is lost packets, which compounds the latency and throughput issues. Other concerns in these software oriented switches are security of the data and “hackability” of the underlying protocols. This presentation provides details of a radically new approach to network technology. By eliminating the switching software altogether, this new approach overcomes the inefficiency and overhead within switched networks. Instead, routing is accomplished in hardware with a highly efficient protocol. An additional feature of this new technology is support for true multicast that will enable advances in network usage methodologies. Together, these improvements bring lossless packet transfers, higher throughput, lower latency, determinism and greatly improved security to network implementations. As the industry moves to memory centric computing and distributed processing designs, we will show how the technology presented supports the scalability, reliability, throughput and security necessary to drive the next evolutionary steps in our industry."
