A computer-implemented system and method for identifying stale configurations of a software-defined network (SDN) component uses a configuration export file of the SDN component to generate configuration dependency strands for configurations of the SDN component. The configuration dependency strands can then be classified as being stale based on at least one of path length, reference count and a custom attribute to elements in a network infrastructure for the configuration dependency strands.

A computer-implemented system and method for generating a correlation directed acyclic graph (CDAG) of configurations of a software-defined network (SDN) component for migration from a source computing environment to a destination computing environment uses a configuration export file of the SDN component to draw the CDAG. Correlation keys defined in the configuration export file are used to draw graph nodes. Contents associated with the correlation keys and template entries are used to draw edges between at least some of the graph nodes. The CDAG with the graph nodes and the edges is then displayed.

System and method for generating correlation directed acyclic graphs for software-defined network components

A system and method for migrating configurations of a software-defined network (SDN) component from a source computing environment to a destination computing environment uses a configuration export file that includes a metadata section and a templates section. The metadata section includes correlation keys for dependencies found in fetched configurations of the SDN component that correspond to dependency keywords in a configurable dictionary. The templates section includes reframed configurations of the dependencies with at least one reference to the correlation keys in the metadata section. At least some correlation-key references within reframed configurations in the templates section of the configuration export file are substituted with correlation-key replacements for the destination computing environment, which are then applied to a target SDN component in the destination computing environment.

System and method for migrating network policies of software-defined network components

A network management server allocates network addresses to a network gateway connected to a public network after receiving an allocation request that specifies a number of network addresses to allocate to the network gateway. The network management server determines a first and second subnets of the public network having, respectively, first and second pools of available network addresses capable of being allocated to devices on the public network, and allocates one or more available network addresses from the first and second pools to the network gateway.

Multi-subnet participation for network gateway in a cloud environment

Multiple tenants within a hybrid cloud computing system may need IP addresses to communicate over a computer network external to the hybrid cloud system (such as the Internet). IP addresses are a scarce resource, and each address can only be assigned to a single tenant. With multiple tenants competing for IP addresses, many request collisions may occur if tenants request IP addresses in a na&#xef;ve manner, such as by requesting the next available IP address numerically. When a collision occurs, a tenant must request a different IP address. Instead, tenants request random IP addresses within a particular subnet in a random manner, thereby reducing the number of collisions that occur and improving the latency associated with requesting an IP address.
