Shawn and I presented a proposal for a 100G (CGMII) Extender at the Long Beach meeting. The goal of the 100G (CGMII) Extender was to put the architecture framework in place to support the new 100GBASE-ZR
PHY (and assuming this PHY would need a new and more powerful FEC). http://www.ieee802.org/3/cn/public/19_01/nicholl_3cn_01a_0119.pdf During the discussion following the presentation in Long Beach, several questions were raised around the details of the MDIO register mappings and MMD numbering for the proposal baseline.
A small group of us got together after the Long Beach meeting to review this topic in the context of several potential 100GbE use cases. This exercise identified a serious issue with the proposed 100G (CGMII)
Extender approach for one of the use cases. An alternative solution based on an Inverse RS-FEC sublayer was identified, and presented at several of the recent ad-hoc conference calls. For those interested in the background and wanting more details on what
drove this change in direction, here are the links to the ad-hoc presentations. http://www.ieee802.org/3/cn/public/adhoc/19_0207/nicholl_3cn_01a_190207.pdf http://www.ieee802.org/3/ct/public/adhoc/19_0214/nicholl_3ct_01_190214.pdf Shawn and I will be making a baseline proposal for the new Inverse RS-FEC sublayer at the Vancouver meeting (see attached).
