Join Greg Sowell for an in-depth discussion in this video Transmission and speed considerations, part of Foundations of Networking: Network Media (WANs).
- Routers act as intersections for networks.…They allow host on one network to reach those on another.…Routers are often sized based on intended use.…A router's performance depends on many factors,…but mainly how much traffic you plan to route through it.…You can have the largest and fastest router,…but if you only have 10 megabits…of internet connectivity route, what's the point?…Routers will also have higher throughput…with larger packets than smaller packets.…So, knowing your traffic profile can be helpful.…
Often high throughput services like Sand,…or database access on servers,…happen on the same layer two segment,…which means it never traverses a router.…So, even if you are moving 10 gigabits between your servers,…your router may not need to be capable…of moving anywhere near that amount of traffic.…Throughput isn't the only determining factor.…Often multiple services will be run on a router…which can affect its capacity.…If a router is managing a firewall, address translation,…or tunnel termination, the overall throughput…
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).
