Luckily, for a DC network, a fabric can be considered as an atomic Luckily, for a DC network, a fabric can be considered as an atomic
structure for management purposes. From this point of view, the structure for management purposes. From this point of view, the
management of the DC network can be decomposed into a set of tasks to management of the DC network can be decomposed into a set of tasks to
manage each fabric separately, as well as the fabric manage each fabric separately, as well as the fabric
interconnections. This way, the overall management task becomes very interconnections. This way, the overall management task becomes very
flexible and makes it easy to expand and adopt to DC networks that flexible and makes it easy to expand and adopt to DC networks that
