RouterOS v7

400G used to mean expensive, complex, and out of reach.

The CRS812 DDQ changes that!

With a modern Marvell switch chip and powerful ARM CPU, it delivers advanced routing, switching, and traffic management features trusted in millions of RouterOS deployments – now with ports up to 400 Gbps!

Where does it fit?

Top-of-rack / leaf switch with 400G uplinks to the spine

Campus core bridging 10G legacy with modern 50G interfaces

Service provider aggregation node

Labs, AI clusters, media workflows where fast “east-west” traffic is critical

All tests are done with Xena Networks specialized test equipment (XenaBay),and done according to RFC2544 (Xena2544)
Max throughput is determined with 30+ second attempts with 0,1% packet loss tolerance in 64, 512, 1518 byte packet sizes
Test results show device maximum performance, and are reached using mentioned hardware and software configuration, different configurations most likely will result in lower results
