For years, we’ve built and maintained networks – complex systems of boxes and protocols ensuring packets flow reliably. But in today's world of distributed applications, multi-cloud deployments, and relentless digital transformation, that’s no longer enough. The network is the platform; it’s the critical path for business

When you type a website address into your browser, a complex series of events unfolds behind the scenes, involving multiple layers of network protocols. This "packet flow" ensures that the website's content reaches your screen. Visiting https://example.com (Secure Connection with TCP/TLS) Visiting a

Have you ever wondered how your email reaches its recipient instantly, or how you can seamlessly stream a movie from across the globe? The unsung hero behind these everyday digital marvels is TCP/IP, the Transmission Control Protocol/Internet Protocol suite. More than just an acronym, TCP/IP is the

You know networks. You build them, optimize them, and troubleshoot them. But have you considered how crucial they are to the AI revolution? The massive scale of modern Machine Learning models isn't possible without distributed training, and that relies on efficient collective communication algorithms. These algorithms orchestrate the

Whether you're setting up a home lab, provisioning virtual machines, or simulating enterprise networks, having your own DHCP server can make things a lot easier. In this guide, I’ll show you how to manually install and configure an ISC DHCP server on Ubuntu, step-by-step. We'll

“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
