Description

扩展端口的处理方法、装置及系统 技术领域
本发明涉及通信领域，具体而言，涉及一种扩展端口的处理方法、装置及系统。
背景技术
随着云计算概念的火热，数据中心网络技术迎来了一次剧烈的变革，大量新技术标准在近几年内出现，各家设备厂商也纷纷投入海量资源来迎接这一新的挑战。随着云计算的发展，虚拟机激增，企业的数据中心也不可避免的引发了管理难题，网络必须适应新的虚拟化技术趋势。于是网络侧针对数据中心的虚拟机迁移等新技术趋势和需求调整做出了一些新的802.1标准。802.1BR标准是IEEE为本地和大城市网络指定的标准，目的就是打破物理的限制，通过802LAN技术和交互接口来扩展桥和桥的管理对象，把大量策略以及安全和管理方面的处理方法从网卡上的虚拟机和刀片服务器上卸下来，将其重新交给连接存储和计算资源的物理以太交换机，简化数据中心系统的管理。借助新的以太网标准，数据中心使用数据中心桥接可以支持融合的网络，进行基于优先级的流量控制，增加拥塞控制。
802.1BR标准建立了一个扩展桥系统，包括控制设备(Controlling Bridge，简称为CB)和一个或多个扩展设备(Port Extender，简称为PE)。CB通过PE客户端服务器协议(Client Server Protocol，简称为CSP)，配置和监控PE。其中PE通过PE CSP定义的扩展端口创建消息(Extended Port Create)向CB报告存在的扩展端口，CB收到消息后，创建一个相应的虚端口，以便用户可以将物理桥的端口通过点对点局域网(Local Area Net work，简称为LAN)连接扩展到远端PE。PE通过端口状态参数设置(Status Parameters Set)消息向CB报告扩展端口的端口状态(MAC_Operational)，CB收到消息后，将扩展端口的MAC_Operational状态通过链路状态(MAC_Enabled)参数反馈到相应的虚端口。
CB在最初创建对应虚拟端口无法直接获知PE的状态。目前多数设备厂商采用的方法是，在PE启动后，只将MAC_Operational状态为通(TRUE)的扩展端口通过扩展端口创建消息(Extended Port Create)通报给CB设备，CB收到消息后直接将相应虚端口的MAC_Enabled置为TRUE。该方法的缺点是MAC_Operational状态为断(FALSE)的扩展端口无法快速发现和监控，另外如果扩展端口状态由TRUE变为FALSE，就会出现FALSE状态扩展端口可能有对应虚接口也可能没有对应虚接口的情况。
针对相关技术中，控制设备CB无法快速发现和监控扩展设备PE的扩展端口的状态信息的问题，目前尚未提出有效的解决方案。

在本实施例中，将该端口状态反馈至该虚端口包括：
该CB将该端口状态通过用于指示链路状态的参数值反馈到该虚端口。
在本发明的实施例中，还提供了一种扩展端口的处理系统，包括：控制设备CB和一个或 多个扩展设备PE；
该PE向该CB发送扩展端口创建消息，其中，该扩展端口创建消息携带该PE的扩展端口的端口状态；
该CB根据该扩展端口创建消息创建该扩展端口的虚端口，并将该端口状态反馈至该虚端口。
下面结合优选实施例和实施方式对本发明进行详细说明。
本发明的提供的优选实施例，加快了CB对PE扩展端口的发现和监控，避免CB虚端口与PE扩展端口的不一致，同时减少消息发送次数。
本发明的优选实施例提供了一种CB快速发现和监控PE扩展端口的方法，包括：
PE在Extended Port Create消息中直接增加端口参数(Port Status)TLV，携带扩展端口的MAC_Operational状态；
CB收到Extended Port Create消息后，创建一个与扩展端口相应的虚端口，并根据Port Status TLV中MAC_Operational状态，设置虚端口的状态和MAC_Enabled参数。
图5是根据本发明优选实施例的CB和PE组网示意图，如图5所示，CB和PE建立连接，此时PE的三个扩展口的MAC_Operational都处于FALSE状态。
本发明的优选实施例提出的MAC转发条目跨设备的方法在本实施例中主备设备上的相关工作流程如下：
图6是根据相关技术中的CB快速发现和监控PE工作流程的示意图，如图6所示，根据其他设备厂商工作流程，当PE扩展口2、3的MAC_Operational变为TRUE，创建了两个对应的虚端口，此时无法从CB快速发现和监控PE的扩展口1；当扩展口3MAC_Operational再变为FALSE，CB仍然是两个虚端口，此时扩展端口1和3虽然状态相同，但CB上只有扩展端口3的对应虚端口，没有扩展端口1的虚端口，只可以监控扩展端口3。
图7是根据本发明优选实施例的CB快速发现和监控PE工作流程的示意图，如图7所示，根据本发明优选实施例的工作流程，当CB和PE建立连接后，PE便将扩展端口1、2、3全部用Extended Port Create消息通知给CB，CB根据该消息创建三个对应的虚接口，此时可以从CB设置和监控PE的三个扩展口的参数；当PE扩展口2、3的MAC_Operational变为TRUE，PE发送Status Parameters Set消息，CB能快速对扩展端口进行监控；当扩展口3 MAC_Operational再变为FALSE，PE也发送Status Parameters Set消息，CB的虚端口状态和PE的扩展端口状态仍然对应保持一致。
本优选实施例公开了一种数据中心网络技术中实现CB快速发现和监控PE的方法，该方法包括：建立一个扩展桥系统，包括CB和一个或多个PE；定义PE CSP协议，以此通过CB配置和监控PE；PE通过PE CSP定义的Extended Port Create消息向CB报告存在的扩展端口；在Extended Port Create消息中增加扩展端口的端口状态(MAC_Operational状态)，CB通过该 消息动态发现PE扩展端口，并获得扩展端口的状态信息。采用本发明后，CB可以快速发现PE设备的扩展端口，并能及时获取到扩展端口的状态信息。
另外，在扩展桥系统中，PE通过Extended Port Create消息向CB报告存在的扩展端口的同时，向CB报告对应扩展端口的MAC_Operational状态；
CB收到Extended Port Create消息后，创建一个相应的虚端口，以便用户可以将物理桥的端口通过点对点LAN连接扩展到远端PE，并将扩展端口的MAC_Operational状态通过MAC_Enabled参数反馈到相应的虚端口；
PE收到Extended Port Create应答消息后，扩展端口的MAC_Enabled参数置TRUE。
在原有PE CSP协议基础上，在Extended Port Create消息中增加一个Port Status TLV，携带扩展端口MAC_Operational状态。
本优选实施例提出了一种数据中心网络技术中实现CB快速发现和监控PE的方法，通过在Extended Port Create消息中直接携带扩展端口的MAC_Operational状态，使CB可以快速发现和监控PE的所有扩展端口，同时减少了Status Parameters Set消息的发送，提高了处理效率。
