TL;DR - 2026 Key Takeaways Spine-leaf remains the default DC fabric in 2026 because it scales predictably with ECMP and repeatable "pods." The biggest performance failures rarely start at the server port-they start in uplink sizing, oversubscription, congestion behavior, and opera...

TL;DR - Key Takeaways 2026 is the "design pivot" year: 400G remains mainstream, but new builds and major expansions increasingly plan around 800G uplinks to avoid near-term bottlenecks. AI changes everything: networking is no longer "plumbing"-it's a performance multiplier. Bandwi...

Introduction If you're planning a new network or upgrading an old one, you will inevitably hit this question: Should I use Layer 2 switches, Layer 3 switches, or both - and where? In 2026, the answer is more nuanced than "L2 is cheap, L3 is advance...

Introduction As industries accelerate toward digital transformation driven by smart manufacturing, energy automation, intelligent transportation, and nationwide smart-city deployments, industrial switches have become indispensable. These devices form the backbone of modern OT (Operatio...

Intro Ethernet switch port types define the performance, scalability, and architecture of modern networks. RJ45 ports serve access-layer copper connections; SFP/SFP+ ports enable flexible 1G/10G uplinks; SFP28 delivers 25G for modern data centers; QSFP+ and QSFP28 support high-density ...

Introduction: Why SMBs Need Reliable SwitchingIn today’s connected business environment, even small and medium-sized companies rely on secure, high-performance networks to keep operations running smoothly. From cloud collaboration to IP telephony and video surveillance, network downtime directly affects productivity...

IntroductionThe Cisco Catalyst 9200-48P and 9300-48P are two of the most widely deployed access-layer switches in enterprise networks. Both offer 48 Gigabit PoE+ ports, but they serve distinct purposes and audiences.The Catalyst 9200 series targets small to mid-size organizations seeking reliable PoE and Layer 2 fun...
