It seems like the bulk of the responses are assuming a point-to-point service. What about aggregation of smaller services? I don't necessarily mean aggregation of hundreds of sub 1 gig circuits, but when you need more than 10 gig, your next step is needing a hundred, even if it's far away. You can only fit so many SLAed multi-gig services on a 10 gig port. This becomes a big deal when cross connects are as expensive as they are -----Mike HammettIntelligent Computing SolutionsMidwest Internet ExchangeThe Brothers WISP ----- Original Message ----- From: Mike Hammett <nanog@ics-il.net> To: NANOG <nanog@nanog.org> Sent: Thu, 26 Dec 2024 20:34:50 -0600 (CST) Subject: MPLS and Carrier Ethernet, Oh My! A few years back, every Tom, Dick, and Harry was touting MPLS or Carrier Ethernet NNIs with 10G ports everywhere. They still are. However, I rarely have seen that graduate to 100G ports and I don't think I've seen anyone talk about 400G ports. Is the hardware not there, or is it more a case of the technology hasn't been deployed widely, so it'll only be seen at a limited number of locations? I'm assuming it's more of the latter as the bigger hardware I've been looking at touts those features and port sizes, but maybe there's some other unadvertised limitation. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP
