    Abstract: According to one aspect, a method includes an Intercloud Fabric Switch (ICS) included in a public cloud and an ICS cluster obtaining a packet, and determining if the packet is obtained from a site-to-site link that links the ICS to an enterprise datacenter. If the packet is obtained from the site-to-site link, it is determined whether the packet is an unknown unicast packet. If the packet is an unknown unicast packet, the packet is dropped, and if not, the packet is provided to an access link that links the ICS to a virtual machine. If the packet is not obtained from the site-to-site link, it is determined whether the packet is obtained from an inter-ICS link that allows the ICS to communicate with the ICS cluster. If the packet is obtained from the inter-ICS link, the packet is dropped if it is an unknown unicast packet.

    Abstract: An example method for a programmable infrastructure gateway for enabling hybrid cloud services in a network environment is provided and includes receiving an instruction from a hybrid cloud application executing in a private cloud, interpreting the instruction according to a hybrid cloud application programming interface, and executing the interpreted instruction in a public cloud using a cloud adapter. The method is generally executed in the infrastructure gateway including a programmable integration framework allowing generation of various cloud adapters using a cloud adapter software development kit, the cloud adapter being generated and programmed to be compatible with a specific public cloud platform of the public cloud. In specific embodiments, identical copies of the infrastructure gateway can be provided to different cloud service providers who manage disparate public cloud platforms; each copy of the infrastructure gateway can be programmed differently to generate corresponding cloud adapters compatible with the respective public cloud platforms.

    Abstract: A method is provided in one example embodiment and includes receiving at a network element a packet including a Network Services Header (“NSH”), in which the NSH includes an Infrastructure (“I”) flag and a service path header comprising a Service Index (“SI”), and a Service Path ID (“SPI”) and determining whether the I flag is set to a first value. The method further includes, if the I flag is set to the first value, setting the I flag to a second value and forwarding the packet to the service function that corresponds to the SI for processing. The method still further includes, if the I flag is not set to the first value, decrementing the SI and making a forwarding decision based on a new value of the SI and the SPI.

    Abstract: Aspects of the instant disclosure relate to methods for facilitating intercloud resource migration. In some embodiments, a method of the subject technology can include steps for instantiating a first intercloud fabric provider platform (ICFPP) at a first cloud datacenter, instantiating a second ICFPP at a second cloud datacenter, and receiving a migration request at the first ICFPP, the migration request including a request to migrate a virtual machine (VM) workload from the first cloud datacenter to the second cloud datacenter. In some aspects, the method may further include steps for initiating, by the first ICFPP, a migration of the VM workload via the second ICFPP in response to the migration request. Systems and machine readable media are also provided.

    Abstract: An example method for distributed service chaining is provided and includes receiving a packet belonging to a service chain in a distributed virtual switch (DVS) network environment, the packet includes a network service header (NSH) indicating a service path identifier identifying the service chain. The packet is provided to a virtual Ethernet module (VEM) connected to an agentless service node (SN) providing an edge service such as a server load balancer (SLB). The VEM associates a service path identifier corresponding to the service chain with a local identifier such as a virtual local area network (VLAN). The agentless SN returns the packet to the VEM for forwarding on the VLAN. Because the VLAN corresponds exactly to the service path and service chain, the packet is forwarded directly to the next node in the service chain. This can enable agentless SNs to efficiently provide a service chain for network traffic.

    Abstract: A method is provided in one embodiment and includes receiving at a network element a flow offload decision for a first service node that includes a portion of a service chain for processing a flow; recording the flow offload decision against the first service node at the network element; and propagating the flow offload decision backward on a service path to which the flow belongs if the first service node is hosted at the network element. Embodiments may also include propagating the flow offload decision backward on a service path to which the flow belongs if the flow offload decision is a propagated flow offload decision and the network element hosts a second service node that immediately precedes the service node on behalf of which the propagated flow offload decision was received and a flow offload decision has already been received by the network element from the second service node.

    Abstract: Techniques are provided for implementing a zone-based firewall policy. At a virtual network device, information is defined and stored that represents a security management zone for a virtual firewall policy comprising one or more common attributes of applications associated with the security zone. Information representing a firewall rule for the security zone is defined and comprises first conditions for matching common attributes of applications associated with the security zone and an action to be performed on application traffic. Parameters associated with the application traffic are received that are associated with properly provisioned virtual machines. A determination is made whether the application traffic parameters satisfy the conditions of the firewall rule and in response to determining that the conditions are satisfied, the action is performed.

    Abstract: Many hybrid cloud topologies require virtual machines in a public cloud to use a router in a private cloud, even when the virtual machine is transmitting to another virtual machine in the public cloud. Routing data through an enterprise router on the private cloud via the internet is generally inefficient. This problem can be overcome by placing a router within the public cloud that mirrors much of the routing functionality of the enterprise router. A switch configured to intercept address resolution protocol (ARP) request for the enterprise router's address and fabricate a response using the MAC address of the router in the public cloud.
