Systems and methods of disconnecting a network service provided over a network service path include using a computing device that obtains a service identifier assigned to network service and identifies a port of a network device included in a network service path associated with the service. The computing device transmits a request to the network device for port configuration data of the network device and based on the received port configuration data, determines whether the port is assigned to the network service. If so, the computing devices executes a remediation operation which includes transmitting a reconfiguration command to the network device that is adapted to cause the network device to update the port configuration data to free the port.

A method and a classification configuration module for managing a classification configuration for traffic, related to a service, in a software defined network are disclosed. The classification configuration module receives the classification configuration from a service related module. The classification configuration includes a first indication indicating a traffic treatment for the traffic, and a second indication identifying the traffic to be treated according to the first indication for traffic treatment. The classification configuration module determines, based on the classification configuration, a set of traffic filters for use by a software defined network controlling module to determine a list of service functions implementing the traffic treatment for the traffic. The classification configuration module transmits information relating to the set of traffic filters to the software defined network controlling module.

In general, techniques are described for automatic intent provisioning and management in computer networks. A device comprising a processor, a memory, and an interface may perform the techniques. The processor may obtain a policy that includes high-level configuration data defining a service to be deployed within a network, the high-level configuration data including resource selector criteria that identifies one or more criteria for selecting a resource to support the service from a plurality of potential resources. The processor may also determine, based on the resource selector criteria, the resource to support the service from the plurality of potential resources, and translate the high-level configuration data to low-level configuration data specific to the determined resource. The memory may store the low-level configuration data specific to the determined resource. The interface may enable configuration, when provisioning the service, the determined resource using the low-level configuration data specific to the determined resource.

An example method of provisioning a network service in a cloud computing system includes: defining, at an orchestrator, the network service to include a plurality of network functions; defining, at the orchestrator, network connectivity among the plurality of network functions; identifying a plurality of vendor device managers (VDMs) configured to provision virtual network functions that implement the plurality of network functions; and instructing, by the orchestrator, the VDMs to deploy the virtual network functions having the defined network connectivity.

Systems, computer-readable media, and methods are disclosed for parallel data processing for service function chains with network functions spanning multiple servers. An example system includes a first server hosting a first network function of a service function chain, a second server hosting a second network function of the service function chain, a mirror function deployed in a first switch to replicate a plurality of packets received by the system and to send respective copies of the plurality of packets to the first network function and to at least one of the second network function and a third network function of the service function chain, and a merge function deployed in a second switch to merge respective outputs of the first network function and the at least one of the second network function and the third network function.

Examples herein relate to developing an orchestration plan. Examples disclose the development of a representation of a set of services wherein each service relates to other services via different types of relationships. The examples apply a set of dependency rules for each type of relationship at each service within the set of services such that the application of the set of dependency rules creates inter-service dependencies between state transitions of the set of services. Based on the creation of the inter-service dependencies, the orchestration plan is developed which includes a sequenced order of the state transitions for the set of services.
