Join Greg Sowell for an in-depth discussion in this video Hardware specification, part of Foundations of Networking: Network Media (WANs).
- [Voiceover] Switch transmission speeds and capabilities…seem to increase exponentially every few years.…But does this mean you need the newest…$10,000 switch?…Often, the answer is no.…One of the first decisions to make when sizing your switch…is to determine the number of ports you need.…This is easiest to do by starting at the start.…Create a network diagram.…I don't care if you write it on the back of a napkin.…Just draw it out.…If you have an overhead diagram of your office,…this works well too.…
Generally, you will have a single hub telecom closet.…This is known as the MDF, or main distribution frame.…Everything will pull back to here…and generally, this is where your…WAN connectivity terminates.…You will often have some remote areas…that are referred to as IDFs,…or intermediate distribution frames.…The IDFs will all pull back to your MDF.…You can start by counting the drops…at each office or cube area…and measuring the cable distances…to where you plan to put your switches.…
Remember that copper ethernet…has a maximum distance limitation of 100 meters.…
He discusses different WAN technologies and features such as speeds, spans, and price points—including inexpensive options such as VPN. He then covers switches (the devices that connect computers in your building) and routers (devices that control the transmission of network data). Along the way, Greg shows how to build private connections, implement free networking over the Internet, build switch networks, and overlay-routed networks. He'll also introduce different routing protocols, such as OPSF link-state routing and distance-vector routing with RIPv2, EIGRP, and BGP.
Note that this course maps to domains 1 and 2 of the Microsoft Technology Associate (MTA) Networking Fundamentals certification exam (98-366).
