Multi-channel, multi-speed Ethernet universal media access control (MAC) and physical coding sublayer IP (UMAC) CoMira’s multi-channel, multi-speed Ethernet universal media access control (MAC) and physical coding sublayer IP (UMAC) is fully configurable and programmable to support “any rate on any channel” (400G/200G/100G/50G/25G/10G/1G). It uses a novel time-sliced architecture that affords maximum density for high port count applications while maintaining industry-leading latencies that are optimized for data center applications. In addition to being compliant with the IEEE 802.3bs, IEEE 802.3-2012, 25G/50G Ethernet Consortium, IEEE 802.3by, and OIF Flex-E Standards, CoMira also offers non-standard and application-driven protocols and modes of operation that allow us to tailor each IP configuration to a customer’s specific needs. This, in turn, lets them better differentiate their own end products.
