Is your AI fabric blind? Static ECMP can’t handle Elephant Flows. Learn how BGP NNHN & Global Load Balancing provide the "X-ray vision" needed to stop congestion and maximize your GPU investment.

“If you don't know what's running in your cloud, your wallet does.” When working in AWS, it's easy to spin up infrastructure and forget about it. Between EC2 instances, Lambda functions, NAT Gateways, and S3 buckets, dormant resources can accumulate quickly—and so can

Abstract This blog post presents a standards-based framework for designing data center networks that support artificial intelligence (AI) and machine learning (ML) workloads using Ethernet VPN (EVPN) and Virtual Extensible LAN (VXLAN) technologies. We outline the key network requirements of AI/ML clusters – including high throughput, low latency, and scalability

Abstract Remote Direct Memory Access over Converged Ethernet version 2 (RoCEv2) is a high-performance networking protocol that brings the low-latency, high-throughput benefits of RDMA to standard Ethernet networks. RoCEv2 extends RDMA’s capabilities over routable Layer 3 (IP) networks, enabling scalable deployments across data center fabrics. This paper provides a
