Abstract: An approach is disclosed for steering network traffic away from congestion hot-spots to achieve better throughput and latency. In one embodiment, multiple Foo-over-UDP (FOU) tunnels, each having a distinct source port, are created between two endpoints. As a result of the distinct source ports, routers that compute hashes of packet fields in order to distribute traffic flows across network paths will compute distinct hash values for the FOU tunnels that may be associated with different paths. Probes are scheduled to measure network metrics, such as latency and liveliness, of each of the FOU tunnels. In turn, the network metrics are used to select particular FOU tunnel(s) to send traffic over so as to avoid congestion and high-latency hotspots in the network.

Abstract: Techniques for stateful connection optimization over stretched networks are disclosed. In one embodiment, hypervisor filtering modules in a cloud computing system are configured to modify packets sent by virtual computing instances (e.g., virtual machines (VMs)) in the cloud to local destinations in the cloud such that those packets have the destination Media Access Control (MAC) address of a local router that is also in the cloud. Doing so prevents tromboning traffic flows in which packets sent by virtual computing instances in the cloud to location destinations are routed to a stretched network's default gateway that is not in the cloud.

Abstract: Techniques disclosed herein permit logical topologies of datacenters to be automatically learned and re-created in the cloud. In one embodiment, a datacenter landscape is determined based on numbers of hops from nodes in a datacenter to a wide area network (WAN)-facing node. Such a datacenter landscape may then be re-created in the cloud. In another embodiment, virtual appliances are deployed using templates with user-tunable parameters. What would have been set up manually in a physical datacenter, such as connecting a new router to other devices, is then simplified to adjusting parameters of the template to specify, e.g., that the router is a routed hop rather than a bump in the wire, with the router then being automatically deployed in the specified manner.

Abstract: Techniques for creating layer 2 (L2) extension networks are disclosed. One embodiment permits an L2 extension network to be created by deploying, configuring, and connecting a pair of virtual appliances in the data center and the cloud so that the appliances communicate via secure tunnels and bridge networks in the data center and the cloud. A pair of virtual appliances are first deployed in the data center and the cloud, and secure tunnels are then created between the virtual appliances. Thereafter, a stretched network is created by connecting a network interface in each of the virtual appliances to a respective local network, configuring virtual switch ports to which the virtual appliances are connected as sink ports that receive traffic with non-local destinations, and configuring each of the virtual appliances to bridge the network interface therein that is connected to the local network and tunnels between the pair of virtual appliances.

Abstract: A hybrid computing system includes an on-premise data center and a cloud computing system. To connect between an organization's multiple data centers, a gateway may instead utilize the connections between the private data center and the cloud computing system rather than a direct connection to the other of the organizations' data centers.

Abstract: Connectivity between data centers in a hybrid cloud system having a first data center managed by a first organization and a second data center managed by a second organization, the first organization being a tenant in the second data center, is optimized. According to the described technique, a path-optimized connection is established through a wide area network (WAN) between a first gateway of a first data center and a second gateway of a second data center for an application executing in the first data center based on performance of paths across a set of Internet Protocol (IP) flows. Application packets received from the application at the first gateway are forwarded to a WAN optimization appliance in the first data center. WAN optimized application packets received from the WAN optimization appliance at the first gateway are then sent to the second gateway over the path-optimized connection.

Abstract: Techniques disclosed herein manage and resolve incidents in hybridity manager applications, without the back-and-forth manual steps of the traditional software support lifecycle. In one embodiment, a virtual network operations center (NOC) with a centralized view of distributed, cross-cloud hybridity manager installations is responsible for tracking incident reports relating to hybridity managers and associated bugs, and the virtual NOC automatically publishes notifications of upgrade builds that fix the tracked bugs to the appropriate hybridity managers. When the same bug is encountered again with another hybridity manager instance, the virtual NOC may also publish an upgrade notification to the other hybridity manager instance, without requiring a support ticket to be filed, etc.
