Yes, they both operate at the link layer and perform the same core function, ie. forward datagrams from port to port (I've never heard of a single port bridge). No, because a brige shares the links between all ports, forwards the datagrams to all ports. A switch selects the right port(s) only, segmenting your network dynamically for the time of transmission; eg. on Ethernet, you get full 10 Mbps on every link, instead of having a shared 10 Mbps for all links. Basically a switch is a better bridge. It should probably be called a switching bridge, but usage, you know... At least that's my understanding. If somebody knows better, I'd love to be corrected. This is really not a FreeBSD question, but I guess you knew that. --Renaud > -----Original Message----- > From: Peter Brezny [SMTP:peter@cyber1.net] > Sent: Wednesday, March 24, 1999 11:03 AM > To: freebsd-isp@freebsd.org > Subject: switch vs bridge > > is a switch the same thing as a multi port bridge? > > thanks. > > Peter Brezny > cyber1.net > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-isp" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
