アリスタは最新のスイッチアップデートで証券取引所をターゲットにしています

アリスタネットワークスは本日、高頻度取引などの超低遅延ネットワークの管理と展開を簡素化することを目的とした、7130シリーズスイッチの一連のアップデートを発表しました。Arista Networks today unveiled a series of updates to its 7130-series switches aimed at simplifying the management and deployment of ultra-low latency networks, like high-frequency trading. Today’s update introduces Arista’s Extensible Operating System (EOS) management platform to the 7130-series switches, alongside a new extension called SwitchApp that allows users to achieve latencies as low as 100 nanoseconds when using traditional network topologies. “SwitchApp is a low-latency application for 7130s, and we’ve also adding support for low-latency protocols … and adding support for Arista Cloud Vision for management purposes,” said Martin Hull, VP of cloud and platform product management, at Arista. “We’re democratizing low-latency switching for the masses.” Acquired with the purchase of Metamako in 2018, the Arista 7130 is a layer-1 switch designed to deliver round-trip latency as low as 45 nanoseconds thanks to the use of an FPGA for switch logic. “The traders want to be able to respond to stimulus that’s coming from the market as quickly as possible with as little latency as possible,” said David Snowden, director of engineering at Arista, adding that because of this the lower the latency that they can achieve over their networks, the faster they can respond to the market. However, achieving these latencies often required the use of complex network topologies and a nonstandard control plane, he explained. “It’s hard to set up and hard to administer, but for the people who care about it, it makes a huge difference,” he added said. The introduction of EOS to the switch aims to address some of this complexity by providing a standard control plane across Arista’s entire switching portfolio all while enabling cloud management via Arista’s Cloud Vision platform. However, for customers that want to achieve the lowest possible latencies over a layer 2-3 network, Arista developed SwitchApp. The extension runs on the switch’s FPGA, and allows users to achieve extremely low latencies without relying on complex network topologies. And, because the Arista 7130 is built around an FPGA and not a traditional switch ASIC, Snowden notes that SwitchApp can be tailored to a customer’s specific use case to balance bandwidth and latency requirements. Beyond high-frequency trading, Arista sees several use cases for SwitchApp including multi-layer multi-chassis link aggregation-based leaf-spine networks, and multicast publish and subscribe trading networks. EOS and SwitchApp are available for the Arista 7130 switch platform for testing today with a final release slated for the second quarter of 2021.
