Lightfleet’s Multiflo™: The World’s First True On-chip Multicast Interconnect

CAMAS, Wash. — (BUSINESS WIRE) — January 14, 2019 — Lightfleet Corporation ( has both issued and pending patents that will lead to the first implementation of true multicast networking on a multicore processor chip. This solves a fundamental problem that has limited the performance of processor architectures in data-intensive applications. Multicast refers to the ability to send a data packet to multiple destinations simultaneously. This is a capability that is desirable in performance-critical applications where multiple processors need access to the information.

“To make up for the lack of true multicast, Ethernet implementations offer a sequential multicast wherein a packet is replicated in the interconnect and sent out serially to multiple endpoints,” said Dr. Bill Dress, chief architect of the Lightfleet developments. “Such a work-around introduces excessive latency into the transmissions and produces a severe skew in arrival times of the same information at different destinations, while dramatically reducing system throughput.”

Supported by 17 patents issued to date, the Lightfleet developments have enabled a new message-centric networking architecture called Multiflo™, where data flow from source(s) to destination(s) without the need for traditional network switches. “By eliminating the traditional network switch, Multiflo removes the biggest factor limiting the performance of data-centric applications,” said Jay Brandon, Lightfleet Vice President of Sales. “Using our technology will give processor vendors a clear performance advantage over competing products, especially in new markets such as Artificial Intelligence.” The company’s benchmarks show more than a ten-fold performance advantage with multicast over switch-based networks, in addition to significant throughput and latency improvements with unicast.

“Lightfleet’s multicast capability has the potential to fill a big gap in the industry’s Gen-Z next-generation networking specification,” said Dress. “Without true multicast capability, and a switch-free interconnect, the latency problems plaguing today’s network architectures will continue and grow even worse into the future.”
