Hur byggs en stad? Har vi allt tillgängligt vetande samlat när vi tar beslut som ändrar förutsättningen för livet i staden? I ett land med växande befolkning och stark urbanisering är byggandet av stad en grundläggande samhällsfråga. Vem bygger? Hur och för vem byggs det? Och med vilken kunskap? Etnolog Joakim Forsemalm och pedagog Magnus Johansson har utarbetat en metod med en syn på evidens som bestående av fyra delar: den organisatoriska evidensen, som handlar om hur kunskap förmedlas inom organisationer; den professionella evidensen som varje yrkesverksam människa bär med sig; den vetenskapliga evidensen som är ett resultat av forskning samt intressentevidensen, medborgaren, den boendes kunskap om sitt område. I bokens sista del finns en manual för hur det går till att använda metoden i det dagliga arbetet med att planera för, bygga och förvalta städer. Alternativet, att fortsätta mer anekdotiskt gynnar inte uppfyllelsen av politiska mål om rättvisa, hållbara, jämlika städer, eftersom utgångspunkten då baseras på personliga erfarenheter, upplevelser och ideal. Istället måste vi utöva en Evidensbaserad stadsutveckling. Joakim Forsemalm är docent i etnologi och verksam vid Radar arkitektur & planering i Göteborg. Magnus Johansson är loso e doktor i pedagogik på Malmö universitet och har i över tjugo år undervisat och forskat på frågor som rör hållbar stadsutveckling, ofta i nära samverkan med praktiker. Paul Göransson är civilekonom och driver sedan 2015 Urbanivation. Boken är formgiven och illustrerad av Martin Ander.

Software Defined Networks: A Comprehensive Approach, Second Edition provides in-depth coverage of the technologies collectively known as Software Defined Networking (SDN). The book shows how to explain to business decision-makers the benefits and risks in shifting parts of a network to the SDN model, when to integrate SDN technologies in a network, and how to develop or acquire SDN applications. In addition, the book emphasizes the parts of the technology that encourage opening up the network, providing treatment for alternative approaches to SDN that expand the definition of SDN as networking vendors adopt traits of SDN to their existing solutions. Since the first edition was published, the SDN market has matured, and is being gradually integrated and morphed into something more compatible with mainstream networking vendors. This book reflects these changes, with coverage of the OpenDaylight controller and its support for multiple southbound protocols, the Inclusion of NETCONF in discussions on controllers and devices, expanded coverage of NFV, and updated coverage of the latest approved version (1.5.1) of the OpenFlow specification.

Software Defined Networks discusses the historical networking environment that gave rise to SDN, as well as the latest advances in SDN technology. The book gives you the state of the art knowledge needed for successful deployment of an SDN, including: How to explain to the non-technical business decision makers in your organization the potential benefits, as well as the risks, in shifting parts of a network to the SDN model How to make intelligent decisions about when to integrate SDN technologies in a network How to decide if your organization should be developing its own SDN applications or looking to acquire these from an outside vendor How to accelerate the ability to develop your own SDN application, be it entirely novel or a more efficient approach to a long-standing problem

Secure Roaming in 802.11 Networks offers a comprehensive treatise on Wi-Fi 802.11 roaming by comparing/contrasting it to cellular roaming theory and techniques. The book explores the fundamental concepts, basic theory, and key principles of 802.11 networks with roaming capabilities. It helps ensure secure and constant connectivity of laptops, PDAs and other emerging mobile devices. Today, we increasingly expect to find public Wide Local Area Network (WLAN) 802.11 access in our airports, public spaces, and hotels, and we want to maintain our connections when we’re mobile and using 802.11 WLANs. However, 802.11 was not originally designed with roaming capabilities and can’t, in its "pure" form, support seamless roaming between different hotspots and other 802.11 access points. This book details the theory behind various 802.11 extensions to permit roaming and describes how these extensions can be successfully implemented in 802.11 WLANs. It reviews coverage of user authentication in 802.11, as well as roaming between 802.11 and other wireless technologies. It also discusses wireless technologies and application programming interfaces. This book will appeal to RF/wireless engineers and designers, computer/data network engineers, and graduate students.
