Linux Networking

Linux is a powerful operating system and tool. One of the reasons for this is the flexibility of Linux Networking. We will look at what advantages Linux networking has, why Linux Networking has made Linux a powerful platform.

Also we will look at what exciting advances are being made with Linux Networking that will rocket Linux into

the future.


My Experience

Unix user/admin for 16 years

Self-Taught networking

HP OpenView Certified

Veritas NerveCenter Certified


Linux Networking

"Recent changes in the areas of both software and hardware are combining to revolutionize networking."

-- Marcio Saitio,

Director of Technology Cyclades Corporation


Revolution

Linux is positioned to ride the wave of the next revolution in the computer industry


Next Revolution

Further integration of

- Network Devices

- Servers/Services

No longer a clear definition between network and other devices

Added functionality to network devices


Why Linux?

Open Source

Flexibility

Security


Open Source

Open Source is a key to the popularity

of Linux today.


Open Source

Open Source has allowed Linux to grow and expand beyond markets


Open Source

Open Source has allowed Linux to become a fertile growing ground for new ideas


Open Source

Has made Linux a popular "first port" platform for new embedded hardware.


Linux Flexibility

Not locked to one protocol/stack

Uses "common" Unix API's and interfaces


Linux Flexibility

Ability to add and modify where needed/wanted


Linux Security

Allow you to manage your own level of security


Revolution Examples
