Abstract: A system may include a set of 4N packet processors and a switching fabric to interconnect the set of 4N packet processors. The switching fabric may include the following switching elements having a size of at least 3N×3N: a first switching element, a second switching element, a third switching element, and a fourth switching element. The first switching element may be directly connected to the second switching element and the third switching element, and may be indirectly connected to the fourth switching element. The second switching element may be directly connected to the fourth switching element, and may be indirectly connected to the third switching element. The third switching element may be directly connected to the fourth switching element.

Abstract: A system may comprise a first group of switches, each switch including a first group of inputs and outputs, and a first group of controllers, each controller being independent from one another and corresponding to a switch of the first group of switches, to selectively control the switch to connect the switch's inputs with outputs. The first group of switches and controllers may be installed in a chassis. The system may comprise a second group of switches, each switch including a second group of inputs and outputs, and a second group of controllers, each controller corresponding to a switch of the second group of switches, to selectively control the switch to connect the switch's inputs with outputs. The second group of controllers may control and connect, via a group of control links, to the first group of controllers.

Abstract: A disclosed computing device capable of instantly switching over between routing engines may include (1) a packet forwarding board configured to (A) forward control traffic via a first link to a traffic replication device and (B) forward data traffic via a second link to a first routing engine, (2) the traffic replication device configured to (A) replicate the control traffic received from the packet forwarding board and (B) select control signals received from the first routing engine, (3) the first routing engine configured to receive control traffic from the traffic replication device, and (4) a second routing engine configured to receive control traffic from the traffic replication device. Various other apparatuses, systems, and methods are also disclosed.
