  • Switching fabric topology based on traversing asymmetric routes
    Patent number: 10291551
    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.

  • Multi-mode switch interface board
    Patent number: 10257001
    Abstract: A switch interface board may include a first serializer/deserializer to communicate with a first group of packet processing components of a first chassis via a first port. The first chassis may house the switch interface board and the first group of packet processing components. The switch interface board may include a second serializer/deserializer to communicate with a second switch interface board of the first chassis via a second port. The second switch interface board may be connected to a second group of packet processing components of the first chassis. The second group of packet processing components may be different from the first group of packet processing components. The switch interface board may include a third port to communicate with a third switch interface board of a second chassis or a switching device of a cross-connect chassis.
