摘要： One embodiment of the present invention provides a system that facilitates traffic isolation (TI) in a network. During operation, the system configures a set of switch ports as members of a TI zone. The switch ports are part of an end-to-end path across one or more switch domains between a source and a destination. The switch ports within the TI zone and outside the TI Zone belong to a common storage area network (SAN) zone which compartmentalizes data for security purposes. The system then determines whether a data flow entering a switch domain belongs to the TI zone. The system subsequently forwards the data flow to the next port within the TI zone if the data flow belongs to the TI zone.

摘要： One embodiment of the present invention provides a system that facilitates end-to-end quality of service (QoS) between a source and a destination in a network. During operation, the system allocates virtual channels on an output port of a switch to a number of quality of service (QoS) levels. The system further assigns a virtual channel to a traffic flow based on a QoS zone, wherein the QoS zone is identified by a host identifier, a target identifier, and a QoS level of the traffic flow. In addition, the system forwards data frames in the traffic flow via the assigned virtual channel.

摘要： An interfabric link between two separate Fibre Channel fabrics so that devices in one fabric can communicate with devices in another fabric without requiring the merger of the two fabrics. The interfabric switch performs a conversion or a translation of device addresses in each fabric so that they are accessible to the other fabric. In a first embodiment the external ports of the interfabric switch are configured as E_ports. A series of internal ports in each interfabric switch are joined together forming a series of virtual or logical switches. In a second embodiment the external ports are configured as NL_ports and the connections between the virtual switches are E_ports. The virtual switches in the interfabric switch match domains with their external counterparts so that the virtual switches effectively form their own fabric.

摘要： An interfabric link between two separate Fibre Channel fabrics so that devices in one fabric can communicate with devices in another fabric without requiring the merger of the two fabrics. The interfabric switch performs a conversion or a translation of device addresses in each fabric so that they are accessible to the other fabric. This translation is preferably done using a private to public loop address translation. In a first embodiment the external ports of the interfabric switch are configured as E_ports. A series of internal ports in each interfabric switch are joined together forming a series of virtual or logical switches. The virtual switches are then interconnected using private loops. The use of the private loop is enabled by the presence of translation logic which converts fabric addresses to loop addresses and back so that loop and fabric devices can communicate. Because each port can do this translation and the private loop addressing does not include domain or area information, the change in addresses between the fabrics is simplified. In a second embodiment the external ports are configured as NL_ports and the connections between the virtual switches are E_ports. Thus the private to public and public to private translations are done at the external ports rather than the internal ports as in the prior embodiment. The virtual switches in the interfabric switch match domains with their external counterparts so that the virtual switches effectively form their own fabric, connected to the other fabrics by the private loops.
摘要翻译：两个单独的光纤通道结构之间的界面链接，使得一个结构中的设备可以与另一个结构中的设备通信，而不需要两个结构的合并。接口交换机执行每个结构中的设备地址的转换或转换，使得它们可被另一个结构访问。该翻译优选地使用专用到公共循环地址转换来完成。在第一实施例中，该互连开关的外部端口被配置为E_端口。每个接口交换机中的一系列内部端口连接在一起形成一系列虚拟或逻辑交换机。然后，虚拟交换机使用专用循环进行互连。通过存在转换逻辑可以实现私有循环的使用，转换逻辑将结构地址转换为循环地址并返回，以便循环和结构设备可以进行通信。因为每个端口都可以进行这种翻译，而私有循环寻址不包括域或区域信息，因此简化了这些结构之间的地址变化。在第二实施例中，外部端口被配置为NL_ports，并且虚拟交换机之间的连接是E_ports。因此，私有的公共和公共的私有转换是在外部端口而不是内部端口完成的，如在先前的实施例中那样。互连交换机中的虚拟交换机与其外部对等体匹配域，使得虚拟交换机有效地形成自己的结构，通过私有环路连接到其他结构。
