 In today's business world, it is crucial to be able to
manage large, complex networks in an efficient and cost-effective manner. Network
Management, MIBs and MPLS: Principles, Design and Implementation makes such
management possible. Widely-experienced engineer and network management specialist
Stephen Morris discusses how, the skillful use of MIBs (management information
bases) and network management system (NMS) technology, can be used to help solve
some of the management problems associated with running large footprint enterprise
and service provider networks. These problems include issues of wide technology
mix (ATM, FR, Ethernet, IP, MPLS etc.), the increasing need for real time IP
traffic, the need for strong security, scalability (the latter is possibly the
biggest single problem facing network managers).  Peer to Peer Computing: The Evolution of Disruptive Technology
takes a holistic approach to the affects P2P Computing has on a number
a disciplines. Some of those areas covered within this book include
grid computing, web services, bio-informatics, security, finance and
economics, collaboration, and legal issues. Unique in its approach,
Peer to Peer Computing includes current articles from academics as well
as IT practitioners and consultants from around the world. As a result,
the book strikes a balance for many readers. Neither too technical or
too managerial, Peer to Peer Computing appeals to the needs of both
researchers and practitioners who are trying to gain a more thorough
understanding of current P2P technologies and their emerging
ramifications. Squid is the most popular Web caching software in use today, and it
works on a variety of platforms including Linux, FreeBSD, and Windows.
Squid improves network performance by reducing the amount of bandwidth
used when surfing the Web. It makes web pages load faster and can even
reduce the load on your web server. By caching and reusing popular web
content, Squid allows you to get by with smaller network connections.
It also protects the host on your internal network by acting as a
firewall and proxying your internal web traffic. You can use Squid to
collect statistics about the traffic on your network, prevent users
from visiting inappropriate web sites at work or school, ensure that
only authorized users can surf the Internet, and enhance your privacy
by filtering sensitive information from web requests. Companies,
schools, libraries, and organizations that use web-caching proxies can
look forward to a multitude of benefits.
The first part of the book provides you with an overview of VPN
technology. This part introduces you to VPN concepts and covers the various
elements included in the VPN technology.
The second part covers tunneling concepts. This part also
introduces you to the most important tunneling protocols based on the layers at
which they function. PPTP, L2F, and L2TP, which operate at Layer 2, are covered
in one chapter, while a separate chapter is dedicated to IPSec, which functions
at Layer 3 of the OSI model and has emerged as the most important protocol in
VPN technology.
The third part of this book is aimed at building and implementing
VPNs. This part introduces you to the design considerations you must keep in
mind when you plan your VPN setup and provides generic step-by-step instructions
for VPN implementation. This part also covers the implementation of VPNs on two
of the most popular networking platforms—Windows 2000 and Linux.
The fourth part of this book is dedicated to VPN security issues.
Here, you'll learn about the common security threats your VPN might have to
face. This part also discusses the various complementary security technologies
that can strengthen you VPN solution.
