Barefoot Tofino powered STORDIS switch

Barefoot Tofino powered STORDIS switch

Thomas Edwards from FOX Networks is explaining his P4 program that was first shown at the the European Broadcasting Union (EBU) Network Technology Seminar (NTS) 2018, June 19-20, 2018. 

In a testament to the agility of P4-programmable forwarding planes, the live demonstration builds upon what was shown last year showcasing FOX Networks’ use of a Barefoot Tofino-powered switch from STORDIS. Specifically, this year’s demo will highlight how P4 and Tofino enable the forwarding plane to perform packet processing functions to parse SMPTE ST 2110-20 headers and dynamically compose video from output that is switched using Real-time Transport Protocol (RTP) timestamp and video row number. The open-source P4 program implementing this forwarding plane logic is developed by FOX Networks, and the STORDIS BF6064X is a 64-port 100GB bare-metal switch powered by a 6.5Tb/s capacity Tofino ASIC.
