Networking

Design, build, and operate a Cisco SD-Access campus fabric — greenfield and brownfield — through one realistic, end-to-end project.

Anyone can turn on SD-WAN. Far fewer can design it, migrate a live network onto it without an outage, steer voice and cloud traffic intelligently, prove it's secure to an auditor, and still sleep at night. SD-WAN Fundamentals follows one company through the whole journey — design, build, migrate, secure, operate — so you learn SD-WAN the way you'll actually use it: as a project, end to end.

Aprenda redes na prática, sem perder tempo com teoria demais. O essencial para programadores web que querem entender o que acontece “por trás da tela”.

This expanded chapter, from Phaser Game Starter Kit Collection, leads you through "White Labeled" Role-Playing "Content-as-a-Service" - an innovative approach in "Headless HTML5 Game Design". It provides both front- & back-end encoding. These advanced topics of "full-stack" development is for anyone interested in RPG "trade-secrets" development.

When a 2,048-GPU training cluster running a 400-billion-parameter model sees its iteration time double without triggering a single alert, firing a CPU panic, or dropping a single packet, you don't have a machine health problem : you have a coordination failure. Beyond Uptime is the definitive field guide for Site Reliability Engineers, platform leads, and cloud architects tasked with keeping frontier AI compute running at peak efficiency. Moving beyond deceptive "GPU Utilization" charts, this book uncovers the hidden mechanics of barrier synchronization, lossless network congestion cascades (PFC/ECN), silent PCIe downtraining, and Silent Data Corruption (SDC). Packed with eBPF tracing methods, streaming gNMI telemetry rules, statistical tail analytics (MAD/CUSUM), and dynamic circuit-breaker strategies, Beyond Uptime gives you the battle-tested framework needed to isolate stragglers in minutes rather than days. Stop paying the silent tax on your AI infrastructure!

Learn to build, send, capture and analyze network packets with Scapy, one of Python’s most versatile networking tools. Through practical examples and runnable code, you’ll explore protocols, traffic analysis, PCAP files, custom packet creation and security testing. Whether you’re troubleshooting networks or sharpening your security skills, this book gives you the tools to get hands-on.

Prepare for the CompTIA Security+® SY0-801 V8 exam with a guide that explains the why, not just the what. It has 27 chapters mapped to every exam objective, 135 explained practice questions, performance-based labs, real-incident case studies and full coverage of the new AI topics.

You can build software with an AI coding agent. A shop owner saw your app and asked: "Can you make one for me? I will pay." You said yes — and then the quiet worry arrived. What if the scope grows? What if the code breaks? What if the client asks something you cannot answer? This book is the answer to that worry: a professional, repeatable way to deliver AI-built software to paying clients. Not hype about getting rich. Not a prototype tutorial. The real work — finding suitable jobs honestly, scoping them clearly, building in small checked steps, verifying quality and security, handing over cleanly, and supporting the result for years.

Build your TCP/IP foundation through clear diagrams of layers, addressing, routing, transport, and end-to-end network communication.

Build a practical gRPC foundation through visual explanations of service contracts, remote calls, streaming, reliability, security, and operations.

Understand DNS through clear visual explanations of name resolution, zones, records, caching, security, and practical operations.

A hands-on guide to mitmproxy 12: trust the CA, filter, modify and replay traffic, write Python addons, choose the right proxy mode, intercept mobile apps past certificate pinning, and automate API security tests. Every output shown is a real run against a lab API.

This book is not just a Python course with a networking flavour or a networking course with a few scripts attached. You already know how routing converges, why VLANs leak, and what a half-open TCP session looks like on the wire. What this book adds is the ability to transform that knowledge into code that runs across hundreds of devices, reports accurately on its findings and never makes changes that cannot be undone.

Ingress-NGINX is retired and about half of all clusters still run it. This is the step-by-step playbook for moving production traffic to Kubernetes Gateway API: a verified annotation-by-annotation map (including every no-equivalent case and its workaround), a decision matrix for nine implementations, inventory scripts, zero-downtime cutover and rollback runbooks, and twelve before/after manifests validated against the real CRD schemas.

A capture that's too big, a complaint that's too vague: this book teaches you to get from there to the packets that explain it. Twenty chapters and 80 exercises on real captures take you from your first capture to TLS decryption, scan detection and your own Lua dissector, with the output of commands run in the lab cited on the page so you can check it yourself.
