The Cisco Nexus 3550-F Fusion is built around a unique modular architecture that scales with your network. Three-line card bays provide the flexibility to grow and change connectivity options over time, while two internal module bays allow the device to be upgraded with expanded functionality, adding new capabilities and extending the useful life of the product. At the heart of the architecture is a high-density layer 1 matrix switch. This matrix switch provides low latency programable 10GbE connectivity between all modules. Unlike traditional network switches that operate only at the data-link layer (layer 2), the Cisco Nexus 3550-F Fusion can operate at the physical network layer (layer 1). Layer 1 switching brings the benefits of circuit switching to Ethernet devices. Connections through the device are programmed into a matrix switch ahead of time and remain configured indefinitely. Unlike dynamic packet-based switching this has the advantage of providing very low and deterministic latency. Packets can cross a layer 1 matrix switch in under 5ns (port to port). The layer 1 matrix switch has several useful purposes. It allows the device to tap into connections (for near transparent network monitoring), to patch connections between ports (for electronic network reconfiguration) and to fan-out connections from one port to many (for low latency data replication applications).
