Distinction btw bridges and repeaters q

I'm thinking it would be instructive to expand on the differences between bridges and repeaters. Can repeaters translate one protocol to another, for instance, say, ATM to ethernet or visa versa? It might help to highlight that if that's a distinguishing feature of a bridge.TeeTylerToe (talk) 04:35, 19 April 2016 (UTC)

I've added some examples to the lead, hope that clarifies a bit. ATM and Ethernet are too dissimilar and can't be bridged and even less repeated – you'd need a router. --Zac67 (talk) 17:30, 19 April 2016 (UTC)

I'm pretty sure that's actually the difference, that a bridge is designed to translate one protocol to another. A wwan to ethernet bridge, or wifi to ethernet, or some form of directional wireless, like laser to ethernet. Take, for instance http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=4806687 A bridge bridges the wire protocol, layer 1, but also the layer 2 frame protocol/bus encapsulation or whatever. It's a repeater that's a layer 1 device that can't translate layer 2 protocols like PPP, or WWan, or wimax, or laser or microwave wireless point to point.TeeTylerToe (talk) 13:13, 20 April 2016 (UTC)

References for simple bridging section

I googled "simple bridging" and I couldn't find any good references for it. Can anyone provide a good reference for it?TeeTylerToe (talk) 21:41, 20 July 2016 (UTC)

That url discusses a computing topic. It is data transfer but it is not solidly networking. ~Kvng (talk) 16:50, 13 March 2021 (UTC)

Non-Transparent Bridge (NTB)

It doesn't look like there's a wiki page for Non-Transparent bridging. I think a section should be added on this page. https://lwn.net/Articles/506761/ Thoughts? 143.116.188.1 (talk) 23:39, 26 October 2016 (UTC)

I suppose a non-transparent bridge would be one where the forwarding table is provided manually by an administrator rather than being learned by observing traffic on each side of the bridge. ~Kvng (talk) 16:53, 13 March 2021 (UTC)

Non-transparent bridging is a (somewhat general) term for bridging that changes the frames – either the frame format, the addressing scheme or the address domain (as in your linked example). --Zac67 (talk) 17:45, 13 March 2021 (UTC)

Zac67, so is IP routing an example of non-transparent bridging? ~Kvng (talk) 13:15, 16 March 2021 (UTC)

No, because it is no bridging. Bridging implies forwarding based on link-layer information (usually the destination MAC address). Forwarding based on network-layer information (ie. IP address) is routing. For instance, bridging between Ethernet and ARCNET within a single broadcast domain would require non-transparent bridging (because frame format and addressing are different) with some kind of address translation scheme. --Zac67 (talk) 13:21, 16 March 2021 (UTC)

Filter bridge

I have reverted addition of filter bridge coverage by FT2. The references are WP:PRIMARY and somewhat dated. There is no other mention of the term in Wikipedia. Packet filter, to which this content refers is a firewall technology. Access control list is the technology used these days for filtering on switches. ~Kvng (talk) 14:34, 21 January 2019 (UTC)

Client Bridge

Many routers offer a Client Bridge mode. The router uses wifi to communicate to the internet modem/router and provides a wired connection out of the router. This is used in place of extending the wiring. The two physical wired portions are thus joined/bridged into a single network.

I use a client bridge to provide wifi connectivity to my ATA VOIP phone which requires a wired connection. Please discuss client bridge. — Preceding unsigned comment added by 2001:1970:5164:3D00:223:4EFF:FE84:EF6F (talk) 15:58, 3 February 2024 (UTC)
