2008.02.19 NANOG 42 100Gig standards progress notes
Attempting to get my notes sent out before the v4 internet goes away during the v6-only hour. ^_^; Apologies for typos, omissions, gaps, etc. Matt 2008.02.19 NANOG42 10 gig standards track update Ted Seely starts off the meeting at 10:00 on the dot; please fill out your surveys! There is a green jacket that is in the lost and found pool, if you recognize it, come claim it. survey is also online at www.nanog.org IEEE update on the 100G standard first, and then a panel later. One panelist is missing in action. 802.3ba The next generation IEEE P802.3ba customary slide showing he's not representing IEEE formally. Higher Speed Study Group became the P802.3ba task force Major compromises worked out around the July 2007 plenary session. voted to adopt both 40G and 100G It's now an official task force; ba is both 40G and 100G One amendment to the specification, both will be delivered at the same time. You may see 40G a bit before, but the same spec will be delivered for both. Will do everything ethernet does already, basically. Provide appropriate support for OTN 100G won't do 1m backplane 40G MAC won't do 40km SMF not sure about 10km SMF for 40G Rest are checked off on both: 10m copper, 100m OM3 MMF the 10km SMF will definitely be there for 100G; not sure about 40G Architectural issues being debated in IEEE is solution n lanes of multiple lambdas, or multiple PHY option? See green_01_0108.pdf for more details on grouper.ieee.org For OTN, which is vague, the IEEE and ITU will work together to map 40G and 100G to map into the ODU tiers; 40G maps into ODU3 define new ODU4 for 100G For physical spec, defining how it will work on the wire; will use backplane 10GBASE-KR most likely as basic spec for 40G for copper. For fiber, much clearer; either parallel or ribbon for MMF, WDM for SMF most likely. The 10km and 40km for 40G seems to be making it into a WAN connectivity option rather than just the server aggregation as anticipated. What will it look like architecturally?? same for both speeds? What about management? need to define test patterns, parameters, etc. 10G project spanned from 2002 to 2007; this is an even bigger project, so it's no wonder it's stretching out for a while; anticipated 2010/2011 completion date. Ad hoc efforts started in 2005-2006; about halfway through the process now. Standards board should have spec finished by Q2 2010, with hardware out a year after or so. Future meetings for 2008 mapped out; first draft, 1.0 will be written in September. http://grouper.iee.org/groups/802/3/ check URLs from the slide deck, he went way too quickly through them to see.
