Which one had more overhead a router or a bridge?
a. Routers are more expensive than bridges. b. Routers operate at the first three-layers; bridges operates at the first two layers. Routers are not designed to provide direct filtering the way the bridges do. A router needs to search a routing table which is normally longer and more time consuming than a filtering table. c. A router needs to decapsulate and encapsulate the frame and change physical addresses in the frame because the physical addresses in the arriving frame define the previous node and the current router; they must be changed to the physical addresses of the current router and the next hop. A bridge does not change the physical addresses. Changing addresses, and other fields, in the frame means much unnecessary overhead.
Is there a router that connects both wire and wired devices?
Yes, you can. Many websites can give you specifics on how to do this. I have found a good discussion forum over at verizon.com and in the residential fios internet discussion forum. Since I use Netgear products I have also found good information there also. Example. I've recently bought a 2nd router and only want to use it for the wireless devices in my home office. I want to use the 1st or main router that is connected to the internet as a wired router only since it is closest to all my wired devices. Here is where you need the specifics on how to set up each router and these websites I mentioned will help you with this information. Getting familiar with the terms or options that are used in the router configuration will be most helpful. At least that's what I'm finding out. Now I've got to find the option to turn off the radio wireless section of my 1st router. This is also an option as I may want to leave the wireless turned on with the 1st router but for now I want to experiment with using the newer router with wireless only as it has the latest 'N' or 5ghz frequency used and I plan on using USB N wireless dongles to upgrade my laptops to the faster frequency band. So, now, I've read where I have to set the 2nd router up whereby the wired IP port addresses don't interfere with one another or I could have problems. Once I figure that out then I only need to plug the cat5 or ethernet cable from one lan port of the 1st router and then to a lan port of the 2nd router. In effect, bridging routers. So, now that I've got you confused, go forth and seek out more help and don't be afraid to experiment to see what works. You can always push the default button on your routers and this will reset them back to factory settings as before. Or, maybe you'r a little more advanced and have been logging into your router and found out how you can backup your configuration settings to your pc in a folder somewhere and then just as easily load the configuration file back to the router. This, only if you've made some changes you'd like to keep that you've made in the past and are now your default settings. Good luck, and please, anyone, take the time to add to the discussion area here if you find out more information on any of this for the rest of us. It seems to be a new and challenging subject for the most of us and it's only going to get worse in the future as we add more and more devices to the internet.
