Abstract
Systems and methods of Ethernet path selection in a modular network element including one or more ingress line modules, a plurality of switch modules in a chassis, and one or more egress line modules, wherein the one or more ingress line modules and the one or more egress line modules are located separate from one another and connected to the chassis via cabling. The method includes distributing one or more Ethernet flows from the one or more ingress line modules to the one or more egress line modules via the plurality of switch modules; receiving fabric state information at the one or more ingress line modules from the core chassis out-of-band via the cabling; and, responsive to congestion on a path through the plurality of switch modules, selecting a new path by an ingress line module for an Ethernet flow.
