Andreas Bechtolsheim, co-founder and chief architect of Arista Networks, has been speaking about the challenges of scaling network infrastructure for artificial intelligence. In a November 2025 podcast, he stated that Ethernet switches designed for AI are "a whole different breed" that must be "purposely designed to optimize that throughput." He argued that the Transmission Control Protocol (TCP) is "not good for AI" and described the Ultra Ethernet consortium's work on a standardized, hardware-based transfer protocol that guarantees packets are not dropped. Bechtolsheim also noted that while renting graphics processing units (GPUs) by the hour is often cheaper than owning them unless they are used constantly, the problems he described primarily apply to clusters of "hundreds of thousands of GPUs." In March 2025, Bechtolsheim discussed the market for 1.6 terabit pluggable modules, predicting that 600 gigabit pluggable modules would "dominate the market by the second half of next year" due to their lower cost per bit and better reliability. He stated that "AI will use more bits than anything" but that this demand is "highly concentrated with the large cloud people" who require the highest reliability, lowest power, and lowest cost. Bechtolsheim also commented on the state of Moore's Law, stating in a 2022 keynote that it is "back on track" and that TSMC, Samsung, and Intel have published roadmaps to two nanometer and beyond.

OFC INSIGHTS: FIVE MINUTES WITH Andreas “Andy” Bechtolsheim, the Chairman, Chief Development Officer and Co-Founder of Arista Networks. He was also a speaker at this year’s Optica Executive forum in Session 5: Photonic Interconnects in AI Clusters. Since the forum is deliberately a closed session, we caught up with Andy on the OFC Conference & Exhibition floor to ask his opinion on what he’s seen here this week in San Francisco. In this deep-tech chat, we discuss the next steps for 1.6TB pluggable modules. Will it dominate the market by 2Q 2026? Could we expand to 3.2 TB by doubling the numbe…

Andy Bechtolsheim, Founder, Chief Development Officer & Chairman at Arista Networks sits with Stu Miniman @stu and John Furrier @furrier live from VMworld 2018 in Las Vegas, NV. #VMworld #theCUBE https://siliconangle.com/2018/08/31/v... Andy Bechtolsheim: The network may end up deciding who wins in the multicloud era Loads of vendors see the enterprise train chugging toward multicloud in all its mismatched glory. Naturally, they want to sell customers the panacea that fits all those clouds onto a single pane of glass. It’s a lot harder then it sounds. In the end, their efforts may be hope…
Andy Bechtolsheim, Founder, Chief Development Officer and Chairman at Arista, reviews how Arista is preparing for the 400 Gigabit future. While 100G Ethernet is gaining ascendency now, by 2021 he sees the 400G port numbers reaching parity with 100G Ethernet. The optics for this will be powered by 100G per lane, as defined by the 100G Lambda MSA consortium. He further reviews how this standard will allow for more seamless transition to 400G than the standards proposed by the IEEE. Bechtolsheim highlights the rapid growth of 100 Gigabit Ethernet, which is expected to continue its ascendancy un…
