Enterprises are under pressure to meet and exceed the challenges of rapidly increasing bandwidth requirements, including AR/VR (augmented reality/virtual reality) applications, streaming multimedia, IoT proliferation, video applications and high density deployments ..read more

As we all recover from NVIDIA’s exhilarating GTC 2024 in San Jose last week, AI state-of-the-art news seems fast and furious. Nvidia’s latest Blackwell GPU announcement and Meta’s blog validating Ethernet for their pair of clusters with 24,000 GPUs to train on their Llama 3 large language model (LLM) made the headlines. Networking has come a long way, accelerating pervasive compute, storage, and AI workloads for the next era of AI. Our large customers across every market segment, as well as the cloud and AI titans, recognize the rapid improvements in productivity and unprecedented insights an ..read more

Welcome to the digital age, where the marvels of self-driving cars and sophisticated AI like ChatGPT grace our everyday lives. Yet, amidst these advancements, a battleground often goes unnoticed, hidden within the layers of our network infrastructures. It's a world where network teams are the unsung heroes, tirelessly working behind the scenes to keep our digital lifelines seamless and uninterrupted. Today, I want to take you on a journey through Network Observability, a beacon of hope in the relentless quest to avoid outages, understand the impact of change, and quickly and accurately root c ..read more

AWS Cloud WAN Tunnel-less Connect and Arista CloudEOS integrate to accelerate cloud onramp As cloud and multicloud adoption continue to evolve, public cloud providers like AWS continue to introduce more and more tools for enterprise IT to choose from. For example, customers can deploy a virtual router in a Transit VPC and BGP peer with AWS Cloud WAN to interconnect on-premises networks and AWS VPCs. However, GRE or IPsec tunnels are often required for the BGP peering, adding up the network complexity and increasing operational costs ..read more

Back in the early 2000s, store and forward networking was used by both market data providers, exchanges and customers executing electronic trading applications where the lowest latency execution can make the difference in a strategy from a profit to a loss. Moving closer to the exchange to reduce link latency, eliminating any unnecessary network hops, placing all feed handler and trading execution servers on the same switch to minimize transit time, and leveraging high-performance 10Gb NICs with embedded FPGAs all contributed to the ongoing effort to squeeze out every last microsecond to exec ..read more

Recently I attended the 50th golden anniversary of Ethernet at the Computer History Museum. It was a reminder of how familiar and widely deployed Ethernet is and how it has evolved by orders of magnitude. Since the 1970s, it has progressed from a shared collision network at 2.95 megabits in the file/print/share era to the promise of Terabit Ethernet switching in the AI/ML era. Legacy Ethernot* alternatives such as Token Ring, FDDI, and ATM generally get subsumed by Ethernet. I believe history is going to repeat itself for AI networks ..read more

Whether it is something as simple as what kind of coffee to order for your commute to the office, which route to take to avoid traffic, or in my case, whether to support the USA or England in the 2022 world cup group stage game, we all make a myriad of choices every day ..read more

In 2022 we are witnessing many forms of cloud networking pioneered a decade ago by Arista. Cloud models continue to take precedence through the new network as organizations address the scale of machines and network traffic ..read more

There is a continued push to go even “faster.” Lowering port to port latency while maintaining features and increasing link speeds and system density is a significant technology challenge for designers and the laws of physics. Since the first release of Arista’s 7100 and 7150 switch families, the company has been a partner in building best-in-class low latency trading networks that are today deployed in global financial institutions and trading locations. Cutting edge customers took the approach of disaggregating network functions into pools of functionality – extremely fast Layer 1 switching ..read more

As we enter 2022, there is much discussion on the “post-pandemic” world of campus and how it’s changing. Undoubtedly, the legacy 2000 era campus was mired in complexity, with proprietary features, siloed designs, and fragile software ripe for change. This oversubscribed campus is riddled with challenges, including critical outages causing risk-adverse behaviors and labor-intensive roll-outs hampering improvements. The future of the campus has changed as the lines between corporate headquarters, home, remote and transit workers are blurring and creating distributed workspaces. Before the pande ..read more
