L2TP Protocol Implementation and Configuration - Definitive Reference for Developers and Engineers

Richard Johnson.

Summary

"L2TP Protocol Implementation and Configuration""L2TP Protocol Implementation and Configuration" is the definitive, in-depth guide for networking professionals, engineers, and architects seeking mastery over the Layer 2 Tunneling Protocol (L2TP). Beginning with a rigorous exploration of L2TP’s evolution, core architecture, and operational principles, the book demystifies protocol mechanics, from control and data plane separation to session multiplexing and real-world deployment scenarios. The nuanced discussion addresses the modern relevance of L2TP—spanning ISPs, enterprises, and mobile networks—establishing a comprehensive foundation for understanding both classical and contemporary applications.Delving into the detailed protocol specification, the work meticulously covers initialization, AVP negotiation, reliability mechanisms, error recovery, and interoperability challenges. Readers are guided through software design patterns for robust L2TP engines, including memory management, concurrency, multi-threaded processing, and diagnostics. Security receives thorough attention, with a dedicated section to L2TP over IPsec, threat mitigation, authentication schemes, and best practices for modern enterprise and carrier-grade environments. Readers also benefit from practical configuration guidance for servers, clients, authentication integration, and scalable deployment within IPv6 and dual-stack infrastructures.The book’s advanced chapters provide invaluable insights into large-scale provider deployments, hybrid VPN architectures, NAT traversal, and service chaining within SDN and NFV contexts. Extensive coverage of testing, debugging, and performance engineering methodologies ensures readers are well-equipped to validate and optimize implementations. Looking to the future, the text analyzes emerging standards, protocol extensibility, cloud-native architectures, and the impact of SASE on VPN technologies. Illustrated with real-world case studies, this book is an indispensable technical resource for anyone involved in designing, securing, implementing, or operating L2TP-based network solutions.

Healing Psychedelics -...

Micah Stover

A certified psychedelic therapist explores the deeper healing offered by psychedelics to those working through trauma.   “Micah has created a must-read for anyone curious about the healing power of psychedelics. Healing Psychedelics demystifies the process and emphasizes safety and effectiveness, making it an essential guide for both new explorers and seasoned practitioners.” —Jessika Lagarde, psychedelic-assisted medicine facilitator, integration coach, and cofounder of Women On Psychedelics   Psychedelics are showing great promise as a new way to heal trauma and improve emotional wellness. Studies reveal that they can be effective in reducing PTSD, anxiety, and depression symptoms, even in cases that are resistant to other treatments. Stover offers a comprehensive and informative guide for both professionals and patients who are interested in learning more about psychedelic-assisted therapy.   Each chapter reveals a vignette taken directly from the psychedelic space that shows the medicines (medium and macro-doses of MDMA, psilocybin, ketamine, and cannabis), why they were chosen, and the process used for transformation during the sessions. Stover weaves in wisdom from indigenous and Mexican healers and practitioners with application exercises, writing prompts, and journal entries to deepen the reader’s healing journey. These exercises are applicable to all readers, whether you are working on your own or with a therapist.  Healing Psychedelics shows the complete process, enabling the reader to safely unlock the power of psychedelics to heal trauma and transform their life for a brighter future.

Eyes in the Sky - Space...

Andrew May

Over 50 years ago, astronomers launched the world's first orbiting telescope. This allowed them to gaze further into outer space and examine anything that appears in the sky above our heads, from comets and planets to galaxy clusters and stars. Since then, almost 100 space telescopes have been launched from Earth and are orbiting our planet, with 26 still active and relaying information back to us. 
 
As a result of these space-based instruments, such as NASA's iconic Hubble Space Telescope, we know much more about the universe than we did half a century ago. But why is Hubble, orbiting just 540 kilometres above the Earth, so much more effective than a ground-based telescope? How can a glorified camera tell us not only what distant objects look like, but their detailed chemical composition and three-dimensional structure as well? 
 
In Eyes in the Sky, science writer Andrew May takes us on a journey into space to answer these questions and more. Looking at the development of revolutionary instruments, such as Hubble and the James Webb Space Telescope, May explores how such technology has helped us understand the evolution of the Universe.

Invent Now - The Next Leap in...

PhD Salima Bhimani

Decoding how moonshots are built and who gets to build them 
Moonshots shape the future―self-driving cars, space exploration, AI at planetary scale, and beyond. The ambition has been extraordinary. But what if we haven’t been ambitious enough? 
In Invent Now: The Next Leap in Moonshots, Dr. Salima Bhimani―former Chief Strategist for Alphabet's portfolio of Other Bets―reveals how the most transformative moonshots begin as hidden opportunities inside stalled systems, misaligned markets, and overlooked economic terrains. 
Drawing on her experience with companies such as Waymo, Wing, Google X, and DeepMind, Bhimani introduces the Third Space: a new operating lens for building moonshots capable of reshaping industries, activating new markets, and unlocking cascading value at every scale. 
Through personal stories and lessons the book reveals practices for bold experimentation and unlocking unprecedented solutions to emerging global needs and opportunities. Along the way, listeners are invited to wrestle with how moonshots come into being―and to step into the Moonshot Dojo, a space where practice begins.

Carlos Enrique Montenegro Marín,...

Los polihidroxialcanoatos (PHA) son polímeros biodegradables con propiedades similares a los plásticos convencionales, que ofrecen una alternativa sostenible y valorizan los residuos de lodos de depuradora. Su principal desafío de producción es el alto costo. Esta revisión, basada en la metodología PRISMA, se centra en el uso de cultivos microbianos mixtos y materias primas renovables (principalmente, ácidos grasos volátiles de lodos) para viabilizar la producción de PHA. El libro sintetiza investigaciones sobre sustratos, la estrategia de alimentación dinámica aerobia para enriquecer biomasa, condiciones operativas y rendimientos reportados. También se describe el proceso desde la obtención del sustrato hasta la producción del polímero, y se destaca la necesidad de optimizar condiciones para escalar esta prometedora tecnología de base biológica.
