    Abstract: The present disclosure relates to providing shared resources to virtual devices on a network switch. In one example, a switch comprises a plurality of virtual device contexts (VDCs) and a default virtual device context (DVDC). The DVDC stores configuration data that identifies a network resource. The DVDC transmits a reference to the configuration data to each of the plurality of VDCs. Each of plurality of VDCs receives the reference from the DVDC. When the DVDC receive, from the at least one of the plurality of VDCs, a request to access the configuration data via the reference, the DVDC transmits at least a portion of the configuration data to the at least one of the plurality of VDCs. The at least the portion of the configuration data is operable to initiate a connection between the at least one of the plurality of VDCs and the network resource.

    Abstract translation: 本公开涉及向网络交换机上的虚拟设备提供共享资源。 在一个示例中，交换机包括多个虚拟设备上下文（VDC）和默认虚拟设备上下文（DVDC）。 DVDC存储标识网络资源的配置数据。 DVDC向多个VDC中的每一个发送对配置数据的引用。 多个VDC中的每一个从DVDC接收参考。 当DVDC从多个VDC中的至少一个VDC接收经由参考访问配置数据的请求时，DVDC将配置数据的至少一部分发送到多个VDC中的至少一个。 所述配置数据的至少一部分可操作以发起所述多个VDC中的所述至少一个与所述网络资源之间的连接。

    Abstract: An example method for zero touch configuration and synchronization of a service appliance in a network environment includes receiving, at an appliance port on a service appliance, an indication that a switch port on a switch changed from an inactive status to an active status, the appliance port being connected over a network to the switch port, starting a bootstrap protocol, including by receiving at the service appliance from the switch, a bootstrap message from a service executing in the switch, creating, by the service appliance, an empty port channel at the service appliance, adding, by the service appliance, the appliance port to the port channel, and associating, by the service appliance, the service to the port channel in a cache.

    Abstract: In one embodiment, load balancing criteria and an indication of a plurality of network nodes is received. A plurality of forwarding entries are created based on the load balancing criteria and the indication of the plurality of nodes. A content addressable memory of a network element is programmed with the plurality of forwarding entries. The network element selectively load balances network traffic by applying the plurality of forwarding entries to the network traffic, wherein network traffic meeting the load balancing criteria is load balanced among the plurality of network nodes.

    Abstract: Systems, methods, and computer-readable media for creating service chains for inter-cloud traffic. In some examples, a system receives domain name system (DNS) queries associated with cloud domains and collects DNS information associated the cloud domains. The system spoofs DNS entries defining a subset of IPs for each cloud domain. Based on the spoofed DNS entries, the system creates IP-to-domain mappings associating each cloud domain with a respective IP from the subset of IPs. Based on the IP-to-domain mappings, the system programs different service chains for traffic between a private network and respective cloud domains. The system routes, through the respective service chain, traffic having a source associated with the private network and a destination matching the IP in the respective IP-to-domain mapping.
