In a packed headquarters ballroom, Cisco Systems Inc.’s then-chief executive officer John Chambers offered a fond farewell to a star executive and friend, Jayshree Ullal. He celebrated her ability to make complicated things simple and wished her success in her next role. He didn’t expect that much success. Within months of the 2008 party, Ms. Ullal became CEO of Arista Networks Inc., a small startup that has since snagged Cisco customers including Microsoft Corp. and Facebook Inc., and is eating into the share of the networking giant’s most important business. Mr. Chambers couldn’t stand to lose sales, especially to someone he considered family and the rivalry has become personal, according to people close to both executives. Defeating Arista has become a priority for Cisco, a company more than 40 times bigger by annual revenue. In 2013, Ms. Ullal’s image appeared in an internal Cisco presentation pasted onto a bull’s-eye pierced with arrows. “Arm the field, stop the bleeding and fire back,” according to the presentation. Now, the fighting is unfolding in court, where Cisco, once the world’s most valuable company, has accused Arista of stealing its technology. Arista has denied the allegations, saying the Silicon Valley giant sued only because it lacked smart ideas to regain business. Each side has notched incremental wins over the past two and half years with no sign of a resolution.

Comprised of a series of short-lived bursts occurring in clockwork-like succession, pulse wave assaults accounted for some of the most ferocious DDoS attacks we mitigated in the second quarter of 2017. In the most extreme cases, they lasted for days at a time and scaled as high as 350 gigabits per second.
