networking 101

LinuxPlanet: "Last week in our classic Networking 101 series we learned about Border Gateway Protocol, the networking protocol that powers the Internet.

This week Charlie Schluting leads the dive into iBGP-- Internal Border Gateway Protocol-- to learn how to connect all those BGP routers together, and how to route between thousands of computers without going nuts."

LinuxPlanet: "What exactly is the Internet? This article will explain the concepts required to understand BGP, our next Networking 101 topic.

Shipping packets around the Internet requires the cooperation of separate organizations, so it isn't as straightforward as learning about an IGP routing mechanism."

Service providers are all excited about "the cloud" and want us to buy into this vague, mysterious "new" service.

But real geeks want details, not hand-waving. In this installment of the excellent classic Networking 101 series, Charlie Schluting tells us how competing service providers all have to cooperate for the Internet to work at all.

Linux Planet: "In today's installment of the classic Networking 101 series, Charlie Schluting guides us through the vital innards of OSPF, the Open Shortest Path First routing protocol: LSAs (Link-State Advertisements), packet types, and area types.

Knowing these things ensures you will always understand your routing infrastructure, and never make daft mistakes."

LinuxPlanet: "In this installment of the classic Networking 101 series, Charlie Schluting walks us through the whys and wherefores of the OSPF, the popular and robust interior gateway protocol."

People use OSPF when they discover that RIP just isn’t going to work for their larger network, or when they need very fast convergence.

This installment of Networking 101 will provide a conceptual overview of OSPF, and the second part of our OSPF coverage will delve a bit deeper into the protocol itself, as well as OSPF area configurations.

As we continue the classic Networking 101 series, Charlie Schluting gives us a clear, understandable introduction to routing, which is quite possibly the most important part of computer networking.

LinuxPlanet: "To understand something in the networking world, you have to understand the problem it's trying to solve.

Memorizing the configuration options for a certain routing protocol won’t help you until you understand what it’s really doing.

This installment of Networking 101 is designed to be a gentle introduction into the world of routing issues and concepts, arguably the most interesting and important part of networking..."

LinuxPlanet: "ICANN, IANA, IETF, ISOC, IAB, IRTF, SRS, NSI, RIR, NSO-- who or what are these, and what do they have to with what you can do with the Internet?

Charlie Schluting explains the roles of the many organizations and governing bodies that operate behind the scenes."

Linux Planet: "Last week's introduction to TCP promised that this article would enlighten, entertain and obviate all other documentation.

Well the last one isn't quite possible in this much space, but let's go ahead and take a look at TCP operational issues, now that we know a little about what TCP actually is."
