OSPF: A Network Routing Protocol
by Phani Raj TadimetyLearn how routers network using the OSPF (Open Shortest Path First) protocol and unpick Dijkstra's Network Algorithm to see how OSPF performs the calculations to determine the shortest or most appropriate path between two routers. OSPF: A Network Routing Protocol dives deep into the OSPF protocol without sacrificing simplicity in language. All of this is done with running examples and illustrations to clarify concepts and enhance the enjoyment of networking. OSPF: A Network Routing Protocol is an absorbing, comprehensible account of OSPF, including the algorithm which is used for calculating its routes. While OSPF has traditionally been an organizational networking protocol, in these exciting times of Software Defined Networking (SDN), it has assumed an important role in the consolidated data center too. Now that the traditional distinctions between server and network roles are getting blurred, everyone in the data center needs to become familiar with networking and networking protocols. What you'll learn How routers accurately perform dynamic routing (packet forwarding) towards the final destination (despite being blind) What are the fundamentals of the OSI model What is the OSPF protocol What is Dijkstra's Network Algorithm Who this book is for This book is for every computer networking professional, whether a relatively new network initiate, or an experienced veteran.

OSPF and IS-IS: From Link State Routing Principles to Technologies
by Rui ValadasThis book describes and compares both the IPv4 and IPv6 versions of OSPF and IS-IS. It explains OSPF and IS-IS by grounding the analysis on the principles of Link State Routing (LSR). It deliberately separates principles from technologies. Understanding the principles behind the technologies makes the learning process easier and more solid. Moreover, it helps uncovering the dissimilarities and commonalities of OSPF and IS-IS and exposing their stronger and weaker features. The chapters on principles explain the features of LSR protocols and discuss the alternative design options, independently of technologies. The chapters on technologies provide a comprehensive description of OSPF and IS-IS with enough detail for professionals that need to work with these technologies. The final part of the book describes and discusses a large set of experiments with Cisco routers designed to illustrate the various features of OSPF and IS-IS. In particular, the experiments related to the synchronization mechanisms are not usually found in the literature.

OPC Unified Architecture
by Stefan-Helmut Leitner Wolfgang Mahnke Matthias DammThe OPC Foundation defines standards for online data exchange between automation systems. They address access to current data (OPC DA), alarms and events (OPC A&E) and historical data (OPC HDA). Those standards are successfully applied in industrial automation. The new OPC Unified Architecture (OPC UA) unifies the existing standards and brings them to state-of-the-art technology using service-oriented architecture (SOA). Main advantages of the new standard are: Platform-independent technology allows the deployment of OPC UA beyond current OPC applications only running on Windows-based PC systems. OPC UA can also run on embedded systems as well as Linux / UNIX based enterprise systems. The provided information can be generically modeled and therefore arbitrary information models can be provided using OPC UA. This book gives an easy to understand introduction into OPC UA and explains the concepts of the standard and other relevant topics that are not directly addressed by the standard.
OK, Boomer: Using a Landline, Going to the Post Office, and Other Outdated Things You Don't Need Anymore
by Tiller PressA book of classic, hilarious &“OK, Boomer&”-isms, a perfect gift for the Baby Boomers we all know and love. Going to the bank. Leaving voicemails. Making Jell-O molds. Using encyclopedias. Wallpapering bathrooms. There are dozens of ridiculously antiquated items, activities, and phrases that Baby Boomers love—and don&’t realize have been outdated for more than a decade. And for some reason, no matter how hard Millennials and Gen Zers try to bring Boomers into the 21st century, they still don&’t seem to get it. They just can&’t let go of eating meatloaf, going on cruises, or buying fuzzy toilet seat covers. So rather than try to explain something to the Baby Boomers in your life, it might be time to just say, &“OK, Boomer.&” Containing more than fifty of the most common, cliched, and cringe-worthy Boomer-isms, OK, Boomer is a perfect gift for any exasperated Millennial or any Boomer willing to poke fun at themselves.
