For this solution to be marketable, it needs to be extremely cheap, as you're
essentially competing against cheapest consumer grade switches to subrate a
These ports would not be revenue generating, but almost invariably MGMT ports
to legacy equipment, issues like QoS are not relevant, price point is. From
switch POV, packets would be lost on-link when rate exceeds, and TCP would
then decrease rate.
So SFP would need to implement rudimentary buffering and packet dropping.
And as always, it's best if there is some way for these to work without any
configuration, as the moment you need to configure 1 thing, you need to
develop provisioning system and potentially also configuration backups, which
may in some organizations make solution prohibitively expensive compared to
using small switch from existing vendor, which is already supported by
