Feature demand drives per port costs that are not very competitively achieved on 1Gb/s switches. On the plus side the per-port cost of the 10Gb/s and mixed 10/100Gb/s switches with usefully rich features continues to slide. Some use of L2 devices for port demux for bigger iron has been done in the past, I imagine it still works for a number of use cases (cisco sells fabric extenders under a similar rational). > > > > ----- > Mike Hammett > Intelligent Computing Solutions > http://www.ics-il.com > > Midwest-IX > http://www.midwest-ix.com > > ----- Original Message ----- > > From: "Fredrik Korsbäck" <hu...@nordu.net> > To: nanog@nanog.org > Sent: Sunday, November 19, 2017 1:46:53 AM > Subject: Re: Commodity routers/switches > > On 2017-11-19 02:55, mike.l...@gmail.com wrote: >> Howdy! >> >> Looking to replace some edge routers for my small ISP.
