    Abstract: A controller may be used to control client switches in a network that includes non-client switches. The controller may form client domains from groups of client switches that are separated by intervening non-client domains formed from non-client switches. The controller may determine a network domain topology from the client domains and non-client domains. The controller may determine a spanning tree that interconnects the nodes of the network domain topology. The controller may control client switches of the client domains to allow only network traffic between the client domains and the non-client domains along the spanning tree. The controller may use the network domain topology to generate inter-domain forwarding maps. The inter-domain forwarding maps may be used to determine network forwarding paths between end hosts in the network.

    Abstract translation: 控制器可用于控制包括非客户端交换机的网络中的客户端交换机。 控制器可以从由非客户端交换机形成的介入的非客户端区隔开的客户端交换机组中形成客户端域。 控制器可以从客户端域和非客户端域确定网络域拓扑。 控制器可以确定互连网络拓扑的节点的生成树。 控制器可以控制客户端域的客户端交换机，以便只允许沿着生成树的客户端域和非客户端域之间的网络流量。 控制器可以使用网络域拓扑来生成域间转发映射。 域间转发映射可以用于确定网络中的终端主机之间的网络转发路径。

    Abstract: In one embodiment, an n-dimensional resource vector for each of a plurality of resources in a computer network is determined, each n-dimensional resource vector having n property values for a corresponding resource of the plurality of resources. Upon receiving a request for one or more resources of the plurality of resources, where the request indicates one or more desired property values, the techniques convert the desired property values of the request into an n-dimensional request vector, determine a distance between each resource vector and the request vector, and provide a response to the request, the response indicating one or more closest match resources for the request based on the distances.

    Abstract: Techniques are provided herein for distributed and hierarchical rendering and provisioning of cloud services. At a device in a cloud computing system comprising a plurality of hierarchical levels, a cloud service request is received for rendering and provisioning of a virtual data center. A determination is made as to which aspects of the cloud service request are to be satisfied by devices in a first hierarchical level and which aspects of the cloud service request are to be satisfied by devices in a second hierarchical level and in subsequent hierarchical levels. Rendering and provisioning commands are provided to one or more devices in the first hierarchical level that are selected to satisfy aspects of the cloud service request in the first hierarchical level. A subset cloud service request for aspects of the cloud service request that are to be satisfied by devices in the second hierarchical level is sent to a device in the second hierarchical level.

    Abstract: Techniques are provided for a switch to assign proxy FCIDs to endpoint device so that the endpoint devices may achieve FCID mobility by retaining their originally assigned FCIDs. At a switch in a network, e.g., a Virtual Storage Area Network (VSAN), a fabric login request is received from a first endpoint device that is associated with a first FC identifier (FCID) that was previously assigned to the first endpoint device by another switch in the VSAN. The fabric login request is responded to with the first FCID. The first endpoint device is assigned a second FCID associated with a domain of the switch where the endpoint device is directly attached to, and the second FCID is used as a proxy FCID within the VSAN for the first endpoint device. A frame is received from the first endpoint device with a source FCID comprising the first FCID and a destination FCID comprising an FCID for a second endpoint device. The source FCID in the frame is overwritten with the second FCID. The frame is forwarded to the second endpoint device.

    Abstract: Methods and apparatus are provided for improving the configuration, management, and distribution of quality of service information in a fibre channel fabric using zoning mechanisms. Configuration of Quality of Service (QoS) information is made easy by using zones as a classifier for flows. QoS information is included in zone objects, thereby using the existing zone distribution mechanism to distribute QoS information. Devices not part of any zones are placed automatically in the default zone with a default QoS priority level. QoS information for a particular packet is available as soon as the zoning information is obtained.
