7.1. Datacenter Applications Scenario

Datacenters are one of the leading application spaces for next generation Ethernet.

Consider a typical datacenter topology.

Figure 27. Typical Datacenter Network Topology

The interconnection between the spine switches and the lead switches is a 10G/40G/100G backplane.

25GbE is a proposed standard for Ethernet connectivity in a datacenter application space, and takes advantage of the technology defined for 100GbE as four 25 Gbps lanes running on four fibers or copper pairs.
