Arista Networks Unveils Sub 100ns Ultra-low Latency Switch for Financial Services

SwitchApp for Arista 7130, a new ultra-low latency switch that would cut latency to less than a third of existing Arista solutions.

SwitchApp for Arista 7130, a new ultra-low latency switch from Arista Networks (NYSE:ANET), was revealed yesterday. SwitchApp for Arista 7130 is a new ultra-low latency switch from Arista Networks that would reduce latency to less than a third of existing Arista solutions.

SwitchApp is built on the new programmable FPGA technology. It would integrate seamlessly with Arista EOS (Extensible Operating System). Customers can access financial markets at breakneck speeds thanks to the combination of these technologies, which combine the versatility of a full-featured Layer 2/3 switch with the low latency of a finely tuned solution.

Trading and financial services firms depend on their networks’ versatility and performance to adapt to changing market conditions. Arista SwitchApp is a Layer 2/3 switching framework with complete functionality that runs on Arista’s 7130 line of programmable FPGA switches. Layer 2 switching provides ultra-low latency of under 100ns. FPGAs are highly versatile off-the-shelf systems with the added advantage of gate-level app configurability.

“ASX has been an Arista client for many years using successive generations of low latency switches, 7130 hardware, FPGA applications, EOS and the CloudVision software,” said David Glavin, GM Technology Infrastructure at ASX (Australian Stock Exchange). “We’re excited about this latest innovation, which brings all of the technologies together, allowing us to unify our network management and monitoring. This adds up to greater efficiency for us and a better outcome for our customers.”

Ultra-Low Latency and Programmability

Arista Networks has taken full advantage of reprogrammability to enable customers to fine-tune their systems to meet changing needs. Arista engineers may bring revolutionary features usually reserved for hardware upgrades to the heart of the switching pipeline through software updates or configuration options for financial services and low latency applications that demand the highest levels of performance, thanks to the FPGA programmability.

“This is a significant step for switch technology,” said Martin Hull, VP Systems Engineering and Platforms at Arista Networks. “SwitchApp is not only Arista’s lowest latency L2/3 switch but offers clients the feature-richness of EOS’s routing stack and operational model. We’ve brought ultra-low latency and programmable FPGAs to EOS, allowing clients to benefit from the simplicity of a single operating system running across their entire estate.”

Network-Wide Model for Provisioning

Clients of Arista can now use EOS to control their entire network, including their ultra-low latency FPGA-based devices, on the same operating system that manages the network core. The Arista 7130 Series is also compatible with Arista’s CloudVision software, which acts as a central control point for third-party overlay controllers, orchestration systems, and security platforms, providing a network-wide model for provisioning, orchestration, and telemetry.

Customers would gain major operational advantages from monitoring to configuration management by using EOS to control their ultra-low latency and FPGA systems, while retaining continuity and a familiar configuration experience and feature set. Since the same EOS program is used in Arista’s entire product line, those with certification criteria just have to certify one software update.

7130 SwitchApp – Application Use Cases

SwitchApp’s ultra-low latency L2/3 features, support multiple deployment scenarios:

  • Exchange-facing with multiple exchange connections, L1 tapping, routing and redundancy
  • Multi-layer MLAG-based leaf-spine including redundant connections
  • Multicast publish and subscribe trading networks

By enabling 7130 Series capabilities in EOS, L1 technology can be used for network tap and monitoring, media conversion, and remote cable management, among other things. Layer 1, 2, and 3 in the same system would allow a hyper-converged high-performance infrastructure with minimal cabling overhead and maximum data center flexibility.

Arista SwitchApp is available for customers testing today, with a generally available release somewhere during the second quarter of 2021.
