Paperback. Condition: new. Paperback. Distance changes everything.A drone may perform perfectly near the launch point, yet become difficult to supervise when terrain blocks the radio path, interference increases, or the aircraft moves outside the reach of a conventional control link. Once an operation depends on cellular communication, the challenge is no longer simply installing a modem and inserting a SIM card.You must understand coverage, latency, handovers, packet loss, routing, security, redundancy, power use, and what the aircraft should do when communication becomes unreliable.Networked Aerial Systems gives you a practical framework for adding cellular communication to unmanned aircraft without treating the connection as something that will always be available.This guide explains how airborne equipment, mobile carriers, ground services, autopilots, operator applications, and remote infrastructure work together. You'll learn how to design the communication path as part of the complete aircraft rather than as an accessory added at the end.Inside, you'll discover how to: - Understand how cellular communication differs from traditional radio control- Choose suitable modems, antennas, SIM options, routers, and onboard processors- Estimate bandwidth requirements for commands, telemetry, payload information, and live media- Measure delay, jitter, packet loss, and signal quality- Position antennas while considering airframe materials and interference sources- Manage tower handovers as the aircraft moves between coverage areas- Route information securely between the aircraft and operator- Use private tunnels, authentication, encryption, and access controls- Reduce unnecessary traffic and prioritize essential messages- Separate flight-critical functions from optional payload services- Design redundant communication paths and automatic failover behaviour- Prepare sensible responses to degraded or completely lost communication- Record performance information for post-flight investigation- Test coverage on the ground before committing equipment to the air- Use simulation, bench checks, and staged flight trials to verify the complete setup- Plan for carrier outages, congestion, roaming restrictions, and unexpected network changesThe explanations are practical and conversational. You won't simply be told that cellular technology provides greater range. You'll learn where it performs well, where it can fail, and how those limitations affect operational decisions.The book also makes an important distinction: a communication link does not replace the flight controller's responsibility for keeping the aircraft stable. Essential actions such as position holding, returning, landing, or following a predefined contingency plan should not depend entirely on a distant server responding at the right moment.You'll also explore why legal authorization, airspace requirements, operational risk, crew responsibilities, and emergency procedures must be considered alongside the technical design. A connection may make a distant mission technically possible, but responsible operation still requires planning, supervision, and clearly defined limits.Whether you're developing inspection platforms, mapping aircraft, research vehicles, delivery prototypes, emergency-response tools, or experimental long-range projects, this book will help you create a more dependable communication architecture.It is suitable for drone developers, robotics engineers, remote pilots, university students, researchers, integration teams, and organizations exploring cellular-supported flight operations.Stop treating mobile communication as an unlimited replacement for conventional radio. Understand the complete path, pre Shipping may be from our UK warehouse or from our Australian or US warehouses, depending on stock availability.…

Taschenbuch. Condition: Neu. Neuware - Your encryption can be strong and your system can still be vulnerable.A database may be encrypted. A master secret may live inside an HSM. Automatic replacement may be enabled. Access may be logged. But none of those controls answers the questions that ultimately determine whether sensitive data remains secure: Who can actually decrypt it What happens when credentials are compromised Can old data survive a replacement What happens when a cloud provider is unavailable Can an organization prove where its most important cryptographic assets are used Cryptographic Key Management in Practice is a practical guide to building the systems behind trustworthy encryption, signing, identity, cloud security, and modern digital infrastructure.Rather than focusing on mathematical derivations, this book shows developers, security engineers, cloud professionals, DevOps and SRE teams, architects, and technical leaders how cryptographic controls work throughout real production environments.You'll learn how to: - Build secure hierarchies using DEKs, KEKs, envelope encryption, KMS platforms, and HSMs- Choose appropriate boundaries for software, hardware-backed, cloud-hosted, and externally controlled assets- Separate possession from permission and enforce least privilege around sensitive operations- Replace active material without breaking applications or losing access to historical data- Prepare for compromise, emergency response, recovery, destruction, and cryptographic erasure- Use workload identities, separation of duties, policy automation, and audit evidence- Architect cloud-native environments across Kubernetes, CI/CD systems, multiple regions, and multiple providers- Evaluate BYOK, HYOK, external control, sovereignty, and vendor-exit requirements- Build inventories and governance systems that remain useful as infrastructure changes- Prepare applications for crypto agility and the transition toward post-quantum standardsRealistic case studies show how apparently secure systems fail through overprivileged identities, version pinning, untested recovery, weak signing workflows, excessive centralization, and incomplete dependency maps.The book concludes with a professional review playbook and a practical learning path that turns the concepts into repeatable architecture, migration, incident-response, and assurance workflows.…

Taschenbuch. Condition: Neu. Neuware - When DNS or DHCP fails, the first complaint rarely says 'DNS' or 'DHCP.' It says the application is down, the network is broken, users cannot connect, or a service suddenly disappeared.DNS and DHCP Operations gives network administrators, infrastructure engineers, system professionals, and technical architects a practical framework for designing, diagnosing, securing, and maintaining the naming and address-assignment services modern networks depend on.Rather than treating DNS as a simple hostname-to-address table or DHCP as a basic lease server, Rion Frost shows how these protocols function as critical infrastructure control planes. You will learn how authority, caching, delegation, leases, relays, client state, security policy, automation, and failure domains interact-and how to identify the real source of a problem instead of troubleshooting by guesswork.Inside, you will discover how to work confidently with authoritative and recursive DNS, resource records, TTLs, zone transfers, DNSSEC, TSIG, split DNS, DNS over TLS, DNS over HTTPS, DNS over QUIC, DHCP scopes and leases, relay agents, DHCPv6, SLAAC, Router Advertisements, prefix delegation, dynamic DNS, IPAM, and high-availability architectures.You will also learn how to troubleshoot real operational failures by tracing state from the client outward, distinguish DNSSEC failures from ordinary resolution problems, diagnose address-pool exhaustion and rogue DHCP services, design resilient multi-site infrastructure, and use logs, packet captures, metrics, synthetic monitoring, and configuration history as evidence.The book also explores infrastructure as code, GitOps, cloud DNS, Kubernetes service discovery, IPv6-first environments, SVCB and HTTPS records, privacy-aware resolver architecture, and responsible AI-assisted operations.With realistic scenarios, diagnostic frameworks, practical commands, architecture diagrams, security guidance, and a structured further-learning path, DNS and DHCP Operations helps you move from basic administration to disciplined operational control.Build naming and addressing infrastructure that remains observable, secure, explainable, and dependable when the network changes-and when something goes wrong.…

Taschenbuch. Condition: Neu. Neuware - Your network should not have to fail before you know it needs more capacity.Modern infrastructure rarely becomes constrained in a clean, predictable way. A WAN link may look healthy on average while busy-hour traffic approaches saturation. A redundant design may have plenty of capacity until one component fails. A cloud migration can move the bottleneck rather than eliminate it. Wi-Fi may offer impressive PHY rates while airtime becomes the real constraint.Capacity Planning for Growing Networks gives network engineers, architects, infrastructure professionals, and technical leaders a practical framework for identifying these problems before performance deteriorates.Rather than treating capacity as a simple bandwidth number, Rion Frost shows how to connect demand, architecture, service objectives, resilience, uncertainty, cost, and delivery time. The book develops capacity planning as a continuous engineering discipline built around trustworthy evidence and timely decisions.Inside, you will learn how to: - interpret utilization, peaks, percentiles, busy-hour behavior, latency, loss, and queueing;- combine counters, flow records, active measurements, topology, and streaming telemetry;- forecast future demand using growth models, scenarios, known projects, and uncertainty;- calculate headroom under normal, maintenance, and failure conditions;- analyze oversubscription, ECMP behavior, shared infrastructure, and traffic matrices;- plan capacity for campus, data center, WAN, internet edge, SD-WAN, cloud, Wi-Fi 6E/7, and Kubernetes environments;- connect infrastructure forecasts to procurement lead times, budgets, decision gates, and upgrade roadmaps;- automate repetitive capacity analysis without replacing engineering judgment.The book moves beyond monitoring to show how to build a defensible capacity story: what is happening now, what is driving it, what is likely to happen next, which resource will constrain first, when a decision must be made, and which response best balances performance, resilience, cost, and flexibility.Practical case studies, expert perspectives, formulas, troubleshooting workflows, planning scenarios, anti-patterns, review templates, and a field toolkit turn the principles into a repeatable operating model for real infrastructure teams.If you want to stop reacting to congestion and start planning infrastructure before the risk becomes an incident, this book provides the framework.…

Taschenbuch. Condition: Neu. Neuware - Enabling IPv6 is easy. Operating it reliably across real production networks is where the difficult work begins.An interface can have an IPv6 address, a router can advertise a prefix, and DNS can publish an AAAA record while users still experience broken paths, hidden fallback, MTU failures, routing asymmetry, first-hop security problems, or dependencies that remain trapped on IPv4.IPv6 Operations for Modern Networks gives network engineers, administrators, architects, cloud professionals, DevOps teams, and technical leaders a practical framework for turning IPv6 from an isolated deployment project into an operational capability.Rion Frost moves from architecture to day-to-day operations, showing how to build scalable prefix hierarchies, plan route aggregation, use IPAM effectively, and make informed choices among SLAAC, DHCPv6, Router Advertisements, static addressing, and DNS configuration.You will learn how Neighbor Discovery changes first-hop behavior, why ICMPv6 is essential, how OSPFv3, IS-IS, BGP, RPKI, multihoming, and route summarization fit into modern designs, and why IPv4 and IPv6 should never be assumed to follow identical paths.Dedicated chapters examine dual-stack transition, IPv6-only networks, NAT64, DNS64, 464XLAT, Happy Eyeballs, application readiness, security policy, RA Guard, temporary-address correlation, extension headers, cloud networking, Kubernetes, automation, infrastructure as code, and governance.Troubleshooting is treated as a proof process rather than a collection of random commands. You will learn how to verify host state, Router Advertisements, neighbor resolution, DNS, source-address selection, routes, firewalls, Path MTU, transport listeners, applications, and translation boundaries in a logical sequence.The book also includes operational case studies, readiness gates, monitoring strategies, change-review questions, a field guide, recommended RFCs, and a practical learning path for developing real IPv6 operating skill.Move beyond simply supporting IPv6. Build a network that can explain it, measure it, secure it, automate it, and repair it with confidence. …

Taschenbuch. Condition: Neu. Neuware - Two routers. Two circuits. Two cloud regions. And still-one outage.Redundancy looks reassuring on an architecture diagram. Production failure is different. A backup circuit may share the same conduit as the primary. Two firewalls may receive the same faulty configuration. Multiple cloud regions may depend on one global identity or policy service. A failover path may work perfectly-until it receives more traffic than it can carry.Resilient Network Architecture shows network engineers, architects, cloud professionals, infrastructure teams, SREs, security practitioners, and technical leaders how to design connectivity that continues delivering useful service when real-world assumptions break.Rather than treating resilience as a shopping list of redundant hardware, Rion Frost builds an end-to-end framework around failure domains, shared fate, blast radius, critical flows, graceful degradation, surviving capacity, recovery dependencies, and testable evidence.Learn how to evaluate active-active and active-passive architectures, N+1 capacity, path diversity, first-hop redundancy, multi-chassis designs, routed access, BFD, OSPF, IS-IS, BGP, RPKI, ECMP, fast reroute, anycast, SD-WAN, DNS traffic management, leaf-spine fabrics, VXLAN/EVPN, and multi-region cloud connectivity.The book goes beyond Layer 3. You will see how load balancers, health checks, timeouts, retries, circuit breakers, queues, session state, identity systems, PKI, security policy, observability, automation, and application behavior can determine whether a network failure remains minor-or becomes a cascading incident.Dedicated chapters examine hybrid and multi-cloud design, security without availability fragility, network observability, disaster readiness, RTO and RPO, infrastructure as code, chaos engineering, game days, digital twins, intent-based networking, and guarded automation.Real incident analysis and practical scenarios show why apparently distributed systems can still contain hidden global dependencies-and why recovery capability must be proven rather than assumed.An extensive Resilience Architecture Review Toolkit helps you map critical flows, identify shared failure domains, define degraded-service contracts, calculate capacity after failure, control change blast radius, demand recovery evidence, design game days, and build measurable improvement cycles.Stop designing networks that merely have backups. Build systems that remain understandable, survivable, and recoverable when the diagram is no longer green.…

Taschenbuch. Condition: Neu. Neuware - What happens when your distributed application leaves the safety of a well-connected cloud region and must keep working across stores, factories, vehicles, remote sites, wireless links, and unreliable WAN connections At the edge, the network is no longer invisible infrastructure. It becomes part of the application's performance, security, availability, and failure model.Edge Networking for Distributed Systems gives developers, network engineers, cloud and platform professionals, architects, and technology leaders a practical framework for designing systems that remain responsive and dependable when distance, congestion, disconnection, mobility, and limited bandwidth become everyday operating conditions.Rion Frost begins with the architectural decisions that matter most: where workloads should run, which dependencies must remain local, how much latency a workflow can tolerate, what should happen when a path degrades, and how systems should recover after connectivity returns.You will learn how to reason about latency budgets, jitter, loss, retries, backpressure, offline queues, state synchronization, correlated failure domains, IPv4 and IPv6, DNS, MTU problems, tunnels, SD-WAN, traffic priority, path diversity, and resilient routing.The book then examines modern application communication through TCP, QUIC, HTTP/3, gRPC, MQTT, WebSockets, datagrams, service discovery, API gateways, load balancing, and Kubernetes service networking. Security is treated as an architectural concern through zero trust, workload identity, mutual TLS, segmentation, SASE, secure enrollment, secrets management, and resilient policy enforcement.Dedicated chapters cover cloud-native edge platforms, GitOps under intermittent connectivity, fleet management, OpenTelemetry, distributed tracing, packet analysis, synthetic testing, and hypothesis-driven troubleshooting. Realistic industry patterns span retail, manufacturing, logistics, healthcare, energy, telecommunications, media, smart infrastructure, and edge AI.A practical field playbook, architecture review checklists, site-acceptance tests, capacity-planning tools, rollout gates, incident-triage guidance, and five reference architecture patterns help turn the concepts into repeatable engineering practice.Design the network as part of the system-not as a dependency you hope will always work.…

Taschenbuch. Condition: Neu. Neuware - Why can a wireless network show strong signal, healthy access points, and impressive speed-test results-yet still deliver a frustrating user experience Reliable enterprise Wi-Fi requires far more than placing access points and maximizing coverage. Client behavior, RF conditions, airtime contention, authentication, roaming, switching, power, DHCP, DNS, security policy, applications, and operational change all contribute to whether the network actually works when users need it.Enterprise Wireless LAN Design and Troubleshooting gives network engineers, administrators, architects, IT professionals, and technically minded practitioners a practical framework for designing, validating, operating, and diagnosing modern business wireless networks.Rion Frost begins by showing how to translate business requirements into measurable wireless outcomes. You will learn how to reason about RSSI, SNR, channel width, interference, airtime, antenna behavior, client asymmetry, capacity, mobility, and RF margins without treating any single metric as universal truth.The book then turns those requirements into real engineering practice through predictive design, site surveys, validation testing, client capability matrices, access-point placement, spectrum strategy, and capacity planning. Learn why wider channels are not always better, why adding APs can sometimes reduce performance, and why the weakest critical client may matter more than the newest device.Dedicated chapters explore 2.4, 5, and 6 GHz operation, Wi-Fi 7 capabilities, Multi-Link Operation, roaming with 802.11k/v/r, WPA3-Enterprise, EAP-TLS, RADIUS, certificate infrastructure, segmentation, guest access, IoT constraints, QoS, real-time voice and video, multicast, and wired-network dependencies.Troubleshooting receives equal attention. Rather than changing settings by instinct, you will learn how to define failures precisely, build hypothesis trees, analyze packet captures and spectrum data, correlate authentication and IP-service evidence, establish baselines, use client cohorts, and distinguish RF problems from identity, switching, WAN, application, or software issues.The book also covers high-density spaces, warehouses, healthcare, industrial environments, outdoor deployments, automation, change control, telemetry, lifecycle management, and future developments in reliability, positioning, sensing, privacy, and intelligent wireless operations.Stop designing for signal alone. Build wireless networks around measurable user experience, reliable mobility, controlled change, and evidence you can defend.That positioning closely matches the manuscript's stated goal of connecting fragmented RF, configuration, authentication, survey, and troubleshooting knowledge into one complete WLAN design model.…

Taschenbuch. Condition: Neu. Neuware - When the route table looks right but traffic still fails, where do you look next Modern network outages are rarely caused by one obvious broken router. A neighbor can remain established while useful routes disappear. A backup link can activate while applications remain unreachable. BGP can make the technically correct decision while traffic takes the wrong business path. And a network can reconverge quickly while users still experience seconds of disruption.Routing and Convergence Troubleshooting gives network professionals a practical framework for diagnosing these problems systematically-without relying on random commands, premature session resets, or guesswork.Instead of treating routing protocols as isolated topics, this book follows the complete decision chain from protocol state to route selection, forwarding installation, packet behavior, and service recovery.Inside, you will learn how to: - Diagnose unexpected traffic shifts and determine exactly why a different route became active- Trace routes through protocol databases, policy, next-hop resolution, the RIB, the FIB, and actual forwarding- Troubleshoot OSPF, BGP, IS-IS, and EIGRP using their underlying state and decision processes- Identify adjacency and session failures before changing configuration- Understand BFD, ECMP, route reflection, redistribution, graceful restart, and route-policy behavior- Detect black holes, recursive next-hop problems, transient micro-loops, route leaks, and control-plane churn- Separate failure detection, propagation, computation, installation, and service validation when recovery is slow- Engineer fast reroute and predictable failover without creating unnecessary instability- Analyze asymmetric traffic, return-path failures, and hidden forwarding-plane problems- Use telemetry, route history, synchronized timelines, and automation to preserve evidence during incidents- Build repeatable troubleshooting workflows that scale from enterprise networks to service-provider and cloud environments- Design routed networks whose behavior remains explainable even under failureThe book's central method is practical: observe what the packet is doing, identify where the decision diverged, then trace that decision backward to the state that produced it. The manuscript explicitly develops this approach across path changes, adjacency failures, protocol-specific diagnosis, loops, black holes, churn, fast recovery, and production incident handling.Whether you are a network engineer, NOC engineer, infrastructure specialist, network administrator, architect, or experienced technician preparing for more advanced operational responsibilities, this book will help you move from checking whether a protocol is 'up' to explaining why the network made the decision it made.Stop troubleshooting devices in isolation. Start troubleshooting the decision chain.…

You will define metrics, validate source data, analyze sales and customers, build funnel and retention analysis, compare results with targets, investigate major variances, reconcile the final numbers, and turn the evidence into useful business conclusions.Whether you are an aspiring business analyst, spreadsheet user moving into databases, student, career switcher, working analyst, or SQL user who wants stronger business context, this playbook gives you a structured path from basic queries to analysis that other people can understand, verify, reuse, and trust.…
