A service partitions a service function chain (SFC) into multiple virtualized network functions (VNFs). The services deploys the VNFs to a smart contract operating in a distributed ledger. The smart contract initiates a bid to service the SFC. Multiple infrastructure providers (InPs) are identified and included in a graph structure. The graph is organized to reflect the order by which the VNFs are to be serviced by the different InPs. The graph also lists the costs the InPs require to service the various different VNFs. The InPs included in a specific graph traversal having the smallest cost are selected, but the cost that is used is the cost for the graph traversal having the penultimate smallest cost. The service outputs the selected InPs as well as the penultimate smallest cost.

Techniques are provided for logical network resource allocation and creation. One method comprises obtaining a representation of virtualized resources to allocate for a logical network within a physical network, wherein the physical network comprises physical nodes and physical links, wherein the virtualized resources comprise virtual nodes and virtual links, and wherein the physical nodes host one or more virtual nodes and one or more of the physical links host a given virtual link; obtaining a first ordered list of the plurality of virtual nodes; obtaining a second ordered list of the plurality of physical nodes; for a virtual node in the first ordered list: selecting and allocating a physical node from the second ordered list as a host for the virtual node; and allocating a physical path for the virtual links associated with the virtual node. The logical network can be created using the allocated physical nodes and physical links.

Logical network resource allocation and creation

Placing virtual network functions (VNFs) in nodes of an infrastructure are disclosed. A request for services may identify a series of VNFs. Requests may be grouped by time windows such that all requests in a time window are placed together. Placing the requests includes identifying which nodes host which VNFs. Some of the VNFs may already exist in the infrastructure. Placing the requests may include generating a placement plan that accounts, for example, for available resources, links in the infrastructure, node restrictions, service level agreements, quality of service requirements, and user priorities. Once generated, the plan is executed. Chains of VNFs can be replaced when service degrades or based on user location.

Dynamic virtual network function placement in edge computing environments

A method for scaling a virtual network function (VNF) by analyzing VNF metrics data, the method that includes obtaining, by a computing device, a VNF metrics data, identifying a queue in the VNF metrics data, calculating a constraint violation probability based on the queue, making a first determination that the constraint violation probability is greater than an upper threshold, and based on the first determination, scaling up the VNF.

Systems and methods for predictive scaling of edge entities

A method for managing a service function chain (SFC) includes obtaining, by a SFC orchestrator of a first domain, a SFC creation request for a SFC, in response to the SFC creation request: generating a domain participation list of a set of potential domains that may service the SFC creation request, sending a bid request to each of the set of potential domains, receiving bid responses from the set of potential domains, ranking the set of potential domains, sending a SFC placement request to a second domain of the set of potential domains based on the ranking, and obtaining a SFC placement response from the second domain, wherein the SFC placement response specifies success of SFC placement in the second domain.
