【FC-FS-2 INCITS 470-2010】标准是关于光纤通道（Fibre Channel）帧格式和信号传输的规范，由美国国家标准协会（ANSI）下属的国际信息技术标准委员会（INCITS）发布。这个标准定义了在光纤通道通信中的数据帧结构和信号传输方式，确保了不同设备间高效、可靠的数据传输。 光纤通道（Fibre Channel）是一种广泛应用于存储区域网络（SAN）、数据中心和高性能计算环境的高速通信协议。FC-FS标准系列，如FC-FS-2和FC-FS-3，旨在规范光纤通道网络的物理层和数据链路层，确保网络的稳定性和兼容性。 FC-FS-2标准详细规定了以下关键点： 1. **帧结构**：包括帧头（Header）、帧数据（Data）和帧尾（Trailer）部分，每个部分都有特定的字段和编码，用于错误检测、流量控制和地址识别。 2. **信号传输**：定义了光纤通道的电气或光信号传输规格，包括信号速率（如1Gbps、2Gbps、4Gbps、8Gbps等）和编码方式。 3. **错误检测与纠正**：采用校验码如循环冗余校验（CRC）来检测传输错误，并可能包含错误恢复机制。 4. **连接协议**：定义了如何建立、维护和断开光纤通道连接，以及如何处理连接故障。 5. **服务质量（QoS）**：提供了优先级标记和资源管理策略，以确保不同类型的流量得到适当的服务。 FC-FS-3是FC-FS-2的后续版本，可能包含了进一步的改进和扩展，例如更高的数据速率支持、增强的错误处理机制或者新的功能特性，以适应技术的快速发展。 在标准制定过程中，INCITS遵循公开评论的程序，允许公众在指定时间内对草案提出意见和建议。这种做法有助于确保标准的公正性和全面性。在2010年8月24日发布的FC-FS-3草案中，公众可以在2010年9月3日至10月18日期间提供反馈，以便在最终确定标准时考虑这些意见。 标准的制定和修订是一个持续的过程，随着技术的进步，如FC-FS-3这样的标准会不断更新以满足新的需求和挑战。用户和开发者在使用这些标准时，必须注意其版本和适用范围，以确保系统设计和实现的合规性。 FC-FS-2 INCITS 470-2010及其后续版本如FC-FS-3，是光纤通道通信的核心标准，它们规定了帧格式、信号传输规范和其他关键功能，对于构建和维护高性能的光纤通道网络至关重要。这些标准的制定和更新反映了信息技术行业的动态发展和对更高效、可靠网络基础设施的持续追求。
