Download Ebook Linux in a Windows World

It began simply enough. A young Finnish student at the University of Helsinki named Linus Torvalds decided to develop his own computer operating system merely as a hobby. More than a decade later, this same operating system has caused nothing short of a revolution in the world of computers.

Now known as Linux, Torvalds’ creation was largely dismissed in the 1990s by tech pundits who claimed that it was unsuitable for the general public’s computing needs. If they only knew how wrong they were! After a series of tweaks from excited developers around the world, Linux’s unparalleled functionality and adaptability have now made it the main alternative to Unix and Microsoft Windows operating systems. And with good reason. System administrators realize that this robust alternative can greatly improve their operating system’s reliabilityand save them money, too. Linux systems are even less vulnerable to attacks by computer viruses and worms. Not surprisingly, businesses, government agencies, schools, and a wealth of other institutions are all looking to Linux to replace the Windows desktop for these same benefits.

Linux in a Windows World takes an in-depth look at exactly how Linux can be brought into an organization that’s currently based on Microsoft Windows systems. Featuring a litany of insider tips and techniques, Linux in a Windows World dispenses all the practical advice you need to migrate to this revolutionary open source software.

Author Roderick W. Smith, himself a renowned system administrator and Linux convert, understands that the skills required to install, deploy, and maintain Linux are not easy to find. That’s why he has tapped the absolute best source of information available: the Linux server experts who have made it their life’s work to build and manage the Linux system.

The latest in O’Reilly’s line of bestselling Linux titles, Linux in a Windows World is an invaluable companion for any system administrator interested in integrating Linux into their Windows environment.

Download Rapidshare Book IMS Multimedia Telephony over Cellular Systems

IMS Multimedia Telephony service has been standardized in 3GPP as the replacement of the circuit switched telephony service in cellular networks. The multimedia telephony service consists of several service components such as voice, video and text. ‘IMS Multimedia Telephony over Cellular Systems’ provides a comprehensive overview of the service that will enable enriched telephony for mobile users. Enriched telephony fulfils the user’s desire to communicate in new ways, for example by sharing pictures and video clips.

In addition to an overview of the Multimedia Telephony service, the book focuses on the modern media processing methods, which allows the quality of the packet switched voice and video telephony not only to match but also possibly exceed the quality of circuit switched telephony. Such key components as adaptive jitter buffering and adaptation of conversational media are explained in detail.

Key features:
Detailed description of how Multimedia Telephony sessions are set-up and controlled
Analysis showing the capacity and quality of VoIP and Multimedia Telephony in cellular networks
Coverage of other IMS services such as PoC specified by 3GPP and OMA
Description of suitable QoS and radio bearers for Multimedia Telephony
Explanation of the modern radio interface, especially High Speed Packet Access, which is based on concepts such as link adaptation and fast hybrid ARQ

The possibilities for the current and future standards covered in this book make it an indispensable resource for engineers, designers and researchers in VoIP, telecommunication companies and universities teaching and conducting research in telecommunications. It will also be of interest to managers needing an in-depth knowledge of the engineering and key issues of this complex technology, and students aspiring to develop a career in this area.
