Oh yes, that's NIC teaming. But I think NIC teaming could be more better than fiber in certain cases in which some remote servers offers only limited connection speed with only a single ip connection for user. User in this case can't connect for more than one session. Fiber won't solve this issue, but teaming does.
Hopelessly my though couldn't come true for this moment. Do wish some special software could overcome this issue & create teaming as my mentioned scenario.
