Mind the MAC GAP (Between 1GE and 100GE)

• We need a 40G MAC/Ethernet to reach a larger market that is
underserved by expensive 10GE products and overserved by 100GE
products.
– Factors of 10 jumps do not fit as many applications as incremental changes
• One Size Fits All – fits very few well
• Interoperability concerns for matching 40GE and 100GE are
unfounded. Ethernet is frame based and resolving lane mismatch has
been accomplished by many vendors.
• For mission critical applications, links usually have to be redundant
– Companies that need redundant 100G links will have to pay at least twice
as much as companies that want redundant 40G links
