摘要： A distributed Fiber Channel over Ethernet (FCoE) Forwarder (FCF) and a distributed Fiber Channel Switch are described. The Distributed FCF is realized by instantiating respective connections between at least one Controlling FCF and a plurality of FCoE Data-Plane Forwarder (FDF) devices and between individual FDF devices. The Distributed FC Switch is realized by instantiating respective connections between at least one Controlling Switch and a plurality of FC Data-Plane Forwarder (FCDF) devices and between individual FCDF devices.

摘要： This document discusses, among other things, applying network policy at a network device. In an example embodiment fiber channel hard zoning information may be received that indicates whether a fiber channel frame is permitted to be communicated between two fiber channel ports. Some example embodiments include identifying a media access control addresses associated with the fiber channel ports. An example embodiment may include generating one or more access control entries based on the fiber channel identifications of the fiber channel ports and the zoning information. The access control entries may be distributes to an Ethernet port to be inserted into an existing access control list and used to enforce a zoning policy upon fiber channel over Ethernet frames.

摘要： In one embodiment, a Fibre Channel over Ethernet (FCoE) proxy point (FPP) that is connected to one or more end-point devices is coupled to one or more other FPPs, and to a FCoE control and management plane (F-CMP) server. The FPP provides data plane functionality. The F-CMP server provides control plane functionality. At least some control and management traffic received at the FPP is proxied between the F-CMP server and the one or more end point devices connected to the FPP. FCoE traffic received at the FPP from the one or more end point devices connected to the FPP is transmitted to the one or more other FPPs without the FCoE traffic traversing the F-CMP server. The transmitting is performed by data plane functionality of the FPP operating under directions from the control plane functionality of the F-CMP server.

摘要： The present invention provides methods and devices for implementing a Low Latency Ethernet (“LLE”) solution, also referred to herein as a Data Center Ethernet (“DCE”) solution, which simplifies the connectivity of data centers and provides a high bandwidth, low latency network for carrying Ethernet and storage traffic. Some aspects of the invention involve transforming FC frames into a format suitable for transport on an Ethernet. Some preferred implementations of the invention implement multiple virtual lanes (“VLs”) in a single physical connection of a data center or similar network. Some VLs are “drop” VLs, with Ethernet-like behavior, and others are “no-drop” lanes with FC-like behavior. Some preferred implementations of the invention provide guaranteed bandwidth based on credits and VL. Active buffer management allows for both high reliability and low latency while using small frame buffers. Preferably, the rules for active buffer management are different for drop and no drop VLs.
