Abstract

Systems, apparatuses, and methods are provided for resilience in network communications. An example system includes at least one first network port including a first plurality of subports and at least one second network port including a second plurality of subports. The system also includes an intermediate switch communicably connected to the at least one first network port and the at least one second network port. At least one of the first plurality of subports includes at least one first offline subport that is inoperable in an instance in which each of the remaining first plurality of subports are operable. The intermediate switch is configured to route communication from one of the second plurality of subports to the at least one first offline subport in an instance in which the intermediate switch receives an indication of a malfunction associated with the first plurality of subports.
