Join Greg Sowell for an in-depth discussion in this video Cable and broadband, part of Foundations of Networking: Network Media (WANs).
- [Voiceover] Cable internet access…is a form of broadband, or high-speed internet…that utilizes existing cable company coax…to deliver service.…The LAN connects to a router,…this router then connects to a cable modem.…The modem generally has an Ethernet interface…that will serve a public internet-routable…IP address to the router.…The modem will also have a coax connector…that will tie the connection to the provider's cable plan.…Cable internet providers can traverse much greater distances…than DSL technologies without using extendors,…upwards of 99 miles.…
Many modern providers now employ…fiber and copper hybrid network.…From their main office, they will use…fiber optic cable to connect to remote nodes.…These nodes can service an area with thousands of users.…Data over cable subscriber interface specification,…better known as DOCSIS, is the international…telecom standard for high-bandwidth…data transfer over coax.…Generally, when referring to differing…service provider capabilities,…it all comes down to what DOCSIS version they are running.…
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).
