A system comprises a plurality of port cards arranged along a first orientation, the port cards operable to receive data from one or more nodes on a network. The system also comprises a plurality of switch-fabric cards arranged along a second orientation orthogonal to the first orientation, the switch-fabric cards operable to route data between the one or more port cards based on one or more rules. The system further comprises a plurality of bridge cards coupling the one or more port cards to the one or more switch-fabric cards, the bridge cards arranged physically between the port cards and switch-fabric cards.

System and method for high connectivity platform

A method includes buffering an initial amount of data of a data set transmitted from a MAC. When an amount of time for data associated with the data set to fill a PHY buffer approaches an amount of time for a far-end PHY to transition from a second far-end PHY power mode to a first far-end PHY power state, a remaining amount of data of the data set transmitted from the MAC is buffered and the data is transmitted to the far-end PHY after it transitions to the first far-end PHY power state. When the amount of time for data associated with the data set to fill the buffer exceeds the amount of time for the far-end PHY to transition to the first far-end PHY power state, a data delay indicator is transmitted to the MAC to preempt the MAC from transmitting the remaining amount of data.
