Abstract: A system, computer-implemented method, and/or non-transitory computer-readable media may provide a warm start technique for cloud-hosted functions. Included is a non-transitory memory storage comprising instructions, and one or more processors in communication with the memory, wherein the one or more processors execute the instructions to identify a cloud-hosted function configured to be executed within a cloud computing environment. The cloud-hosted function is instantiated within the cloud-hosted computing environment. The one or more processors additionally execute the instructions to determine a hold (preservation) time to maintain the instantiation of the cloud-hosted function within the cloud computing environment, based on a plurality of function execution metrics calculated for the cloud-hosted function. The one or more processors further execute the instructions to maintain the instantiation of the cloud-hosted function within the cloud computing environment for the determined hold time.

Abstract: The disclosure relates to technology for coordinating execution of serverless functions. One or more events are received from one or more event sources. The one or more events are mapped to one or more event states of a function graph according to a mapping rule, the one or more event states including one or more actions, and the one or more actions which satisfied the mapping rule are executed. The received events are sent to a computer system to trigger the computer system initiating one or more computing resource groups for executing one or more serverless functions associated with the one or more actions. One or more responses are received from the serverless functions.

Abstract: Packets of data can be processed by a chain or sequence of service functions which include both virtual and physical service functions. In one approach, the original header and/or payload of a packet is analyzed at a software switch to determine whether the packet should be processed by the chain. If such processing is indicated, a next service function to process the packet is identified. The packet is then forwarded to a virtualized or physical device which implements the next service function. A portion of the header, such as a MAC destination address, may be modified to direct the packet to the next function. Further, in some cases, a service function chain (SFC) header with a chain identifier may be added to, or removed from, the packet.

Abstract: An architecture, method, and/or non-transitory computer-readable media provide a service graph based serverless cloud architecture. The service graphs can orchestrate cloud-hosted functions into a coordinated micro-service application, and thus control the execution of the cloud-hosted functions in a prescribed manner. Additionally, service graphs permit a user to arrange cloud-hosted functions to execute in sequence or concurrently, manage error conditions by re-invoking function calls, handle scaling to accommodate varying event loads, and the like. Service graphs also allow a user to define rendezvous points (i.e., states) to wait for pre-defined events before executing a cloud-hosted function and progressing through the service graph. The advantages of coordinating the execution of cloud-hosted functions with service graphs is that the service graphs provide a consistent framework for managing cloud-hosted functions without the user having to solve the coordination problems on their own.

Abstract: System and method embodiments are disclosed here to resolve Internet Protocol (IP) address overlap of Virtual eXtensible Local Area Network (VXLAN) endpoints in packets forwarded between the VXLAN and an external or public network. An embodiment method includes assigning different port number ranges to different virtual private networks of the VXLAN, mapping private IP addresses for endpoints at the virtual private networks to corresponding public IP addresses known to a public network, and mapping local ports of the endpoints to corresponding port numbers from the port number ranges assigned to the virtual private networks, wherein each of the endpoints at the virtual private networks is assigned to a unique combination of public IP address and port number. The mapping can be done at a VXLAN gateway or at the endpoints on physical servers of the virtual private networks.

Abstract: VXLAN inter-domain communications and packet forwarding are supported between a virtual machine (VM) in a Virtual eXtensible Local Area Network (VXLAN) domain and an external client or another domain via a Layer Two (L2)/Layer Three (L3) switch, router, or network. A VXLAN Tunnel End Point (VTEP) coupled to the VM at a server and to the L2/L3 switch, router, or network and associated with the VXLAN domain is configured to implement a method for enabling the VXLAN inter-domain communications. The method includes receiving a packet at the (VTEP), replacing a source or destination Media Access Control (MAC) address in the packet if the packet is part of communications between a VXLAN domain for the VMs and an external component without encapsulating or decapsulating the packet, and forwarding the packet. Alternatively, the VTEP encapsulates or decapsulates an incoming packet if the packet is part of a VXLAN internal domain communications.

Abstract: Metadata may be embedded in a service chain header (SCH) appended to a packet that is forwarded over a service chain path. The metadata may include information that is used to process the packet at a downstream service function chain (SFC) entity on the service chain path. The metadata TLV field may identify a service action to be performed by a downstream SFC entity. For example, the metadata TLV field may instruct the downstream SFC entity to drop the packet, to redirect the packet (or a traffic flow associated with the packet), to mirror a traffic flow, to terminate a communication connection, to start or stop a packet accounting, and/or to apply a higher grade of service. Alternatively, the metadata TLV field specifies an OAM service action list that identifies service actions that have been performed on the packet.
