Disaggregated integrated synchronous optical network and optical transport network switching system
10469168 · 2019-11-05 · ·

Methods and systems of a disaggregated integrated synchronous optical network (SONET) and optical transport network (OTN) switching system that includes using plug-in universal (PIU) modules for OTN to Ethernet transceiving, SONET PIU modules for Ethernet to SONET transceiving, and an Ethernet fabric as a switching core are disclosed. An OTN over Ethernet module in each of the PIU modules and an Ethernet over SONET module in each of the SONET PIU modules may enable various SONET and OTN functionality to be realized using the Ethernet fabric which may include multiple Ethernet switches.

Disaggregated hybrid optical transport network, internet protocol, and Ethernet switching system
10461873 · 2019-10-29 · ·

Systems and Methods for switching optical data units (ODUs) and Internet Protocol (IP) packets as Ethernet packets in an optical transport network (OTN), IP, and Ethernet switching system. The OTN, IP, and Ethernet 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.
