Abstract

Systems and Methods for IP and Ethernet switching in an ultra-scalable disaggregated wide area common carrier (WACC) disaggregated networking switching system. The WACC network switching system may include an Ethernet fabric having a set of M Ethernet switches each including a set of N switch ports, and a set of N input/output (IO) devices each including a set of W IO ports, a set of M Ethernet ports, an IO side packet processor (IOSP), and a fabric side packet processor (FSP). Each Ethernet switch may establish switch queues. Each IO device may establish a set of M hierarchical virtual output queues each including a set of N ingress-IOSP queues and ingress-virtual output queues, a set of W egress-IOSP queues, a set of M ingress-FSP queues, and a set of N hierarchical virtual input queues each including a set of N egress-FSP queues and egress-virtual input queues.
