Re: Long distance links


I only support one rate, 10,000 Gbps at MAC/Plus, and also support 9.58464 
Gbps at WAN/PHY using rate conversion by HOLD, Buffer, variable IPG... etc.  
This approach will enable both LAN (10, 100, 1000, 10,000 Mbps) and WAN (OC1, 
3, 12, 48, 192) maintain backward computability to provide smooth migration, 
and integration for both camps.  

I assume many of us think HSSG definition ends at WAN/PHY input, which I have 
no objection as a definition. 

However, as a user, I have to keep thinking "What is the most cost-effective 
way to implement it in the whole link -- end-to-end."
