该协议是FC协议的FC1~3层协议,是理解FC的基础协议,必看。FC-0层定义了FC中的物理部分,包括光纤、连接器以及不同传输介质和传输速率所对应的光学和电器特性参数。FC-1层中定义了FC的底层传输协议,包括串行编码、解码和链路状态维护。数据帧及数据包的发送和接收是在FC-2(Protocol)层实现的,FC-2层定义了帧结构、命令集、序列、交换、分类服务等内容。FC-3层中定义了一组服务用于公共的单一节点中的多个端口交叉其中包括组搜寻(Hunt Groups)和分组广播(Multicast)。

draft proposed American National Standard
for Information Technology
Fibre Channel –
Fibre Channel Framing and Signaling - 4 (FC-FS-4)
Secretariat
Information Technology Industry Council
Approved dd mmmmm, 200x
American National Standards Institute, Inc.
Abstract
This standard describes the framing and signaling requirements for Fibre Channel links. The Physical
Interface requirements are described in Fibre Channel-Physical Interfaces (FC-PI-x). The Link Services
requirements are described in Fibre Channel-Link Services (FC-LS-3). This standard is recommended for
new implementations but does not obsolete the existing Fibre Channel standards.

v
American National Standard
Approval of an American National Standard requires review by ANSI that the requirements for due
process, consensus, and other criteria for approval have been met by the standards developer.
Consensus is established when, in the judgement of the ANSI Board of Standards Review, substantial
agreement has been reached by directly and materially affected interests. Substantial agreement means
much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and
objections be considered, and that a concerted effort be made towards their resolution.
The use of American National Standards is completely voluntary; their existence does not in any respect
preclude anyone, whether he has approved the standards or not, from manufacturing, marketing,
purchasing, or using products, processes, or procedures not conforming to the standards.
The American National Standards Institute does not develop standards and will in no circumstances give
an interpretation of any American National Standard. Moreover, no person shall have the right or authority
to issue an interpretation of an American National Standard in the name of the American National
Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose
name appears on the title page of this standard.
CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The
procedures of the American National Standards Institute require that action be taken periodically to
reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive
current information on all standards by calling or writing the American National Standards Institute.
PATENT
STATEMENT
The developers of this standard have requested that holders of patents that may be required for the
implementation of the standard disclose such patents to the publisher. However, neither the developers nor
the publisher have undertaken a patent search in order to identify which, if any, patents may apply to this
standard. As of the date of publication of this standard, following calls for the identification of patents that
may be required for the implementation of the standard, notice of one or more such claims has been
received. By publication of this standard, no position is taken with respect to the validity of this claim or of
any rights in connection therewith. The known patent holder(s) has (have), however, filed a statement of
willingness to grant a license under these rights on reasonable and nondiscriminatory terms and conditions
to applicants desiring to obtain such a license. Details may be obtained from the publisher. No further
patent search is conducted by the developer or publisher in respect to any standard it processes. No
representation is made or implied that this is the only license that may be required to avoid infringement in
the use of this standard.
