Which standard provides FCoE with a lossless Ethernet network?

Data Center Bridging (DCB) is a set of IEEE standards that provide a lossless Ethernet network for Fibre Channel over Ethernet (FCoE). DCB enhances Ethernet networks to support the lossless delivery of storage traffic and other high-priority data by incorporating features like Priority-based Flow Control (PFC) and Enhanced Transmission Selection (ETS). These features ensure that storage traffic, such as FCoE, can be transmitted reliably over Ethernet without packet loss.References:= Dell Information Storage and Management V5 course materials
