Microsegmentation

From Wikipedia, the free encyclopedia

Microsegmentation in computer networking is a term used to describe the segmentation of a collision domain into as many segments as there are circuits, minus one (#segments = #circuits - 1). This microsegmentation performed by the switch cuts the collision domain down so that only two nodes coexist within each collision domain. This way, collisions are decreased and only the two NICs which are directly connected via a point-to-point link are contending for the medium.
