Abstract: Three-dimensional (3D) visualization of multi-layer networks include receiving data associated with a network, wherein the network includes interconnected network elements that operate at a plurality of levels that include any of network layers and encapsulations; displaying a plurality of three-dimensional icons each represent one of a plurality of network elements of the interconnected network elements; and displaying links between the plurality of three-dimensional icons each link representing one of a network layer connection and an encapsulation connection.

Abstract: A data transfer system comprising a first bus interface, a second bus interface, a first-in-first-out memory, a controller and a message unit. The message unit is operable to queue a plurality of data transfer request messages from the first bus interface and the second bus interface. The controller is operable to process each data transfer request message and transfer data between the first bus interface, the first-in-first-out memory and the second bus interface. The controller is configured to calculate error detection codes (EDCs) and chain EDC values.
