Designing Large Scale LANs
This unique book offers a vendor-neutral approach for
designing large local area networks according to business
or organizational needs, rather than from a product
perspective. Author and independent network design
consultant Kevin Dooley outlines "top-down network design"
for building a technological infrastructure
to fit your
organization's requirements, a process far more effective
and cost-efficient than fitting the organization to the
parameters of a shrink-wrapped proprietary solution.
Dooley argues that the design of a network is largely
independent of the products used. Whether you use a Cisco
or Juniper router, the same security issues and protocols
apply. The questions he addresses in this book are
need-specific: Do I use a router or a switch? Should I route
between switched areas or switch between routed areas?
Designing Large-Scale LANs covers everything from security,
bandwidth and scalability to network reliability, which
includes backup, redundancy, and points of failure.
Specific technologies are analyzed in detail: network
topologies, routing and switching strategies, wireless,
virtual LANs, firewalls and gateways, security, Internet
protocols, bandwidth, and multicast services. The book also
discusses proprietary technologies that are ubiquitous,
such as Cisco's IOS and Novell's IPX.
This complete guide to top-down network design will help you
choose the right network solutions. If you're designing
large scale networks and need expert advice and guidance,
look no further than Designing Large-Scale LANs.
