Spirent Communications introduced its Fibre Channel over Ethernet (FCoE) test solution to help assess the interaction of storage and data centre traffic over a common interface. Test engineers now have the ability to analyze a number of critical occurrences including the encapsulation of a native Fibre Channel frame into an Ethernet frame, the emergence of Converged Enhanced Ethernet (CEE) to help ensure lossless fabric, and the effect of replacing a Fibre Channel link with MAC addresses in CEE environments. Spirent TestCenter FCoE provides support for FCoE Initialization Protocol (FIP), a control plane protocol, and Priority Flow Control (PFC), the advanced quality of service protocol for Ethernet. Ultimately, users of Spirent’s FCoE solution can easily understand latency issues as well as the impact of packets which are dropped and scenarios such as loss of power.

From the Technology Graveyard
You just read about Ethernet. Here is what it replaced:
Token Bus (802.4) served 1982–1990. What ultimately replaced it?
Token Bus (802.4) formed a logical token-passing ring over a physical coax bus, so factory-floor stations got deterministic, collision-free access (favored by GM's MAP initiative). Its job passed to Ethernet — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
