Abstract
Systems or methods that may be used to assist in distributed flow whereby each network element obtains information from a server so a first network element has information to determine what network element to connect with to create virtual private network tunnels associated with a virtual private network service.
Claims13
A device comprising:
- a processor;
- and
- a memory coupled with the processor, the memory comprising executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
- receiving first information from a plurality of network elements, wherein the first information comprises bandwidth of interfaces, central processing unit (CPU) utilization, and utilization of interfaces, wherein the first information is obtained with use of a hard-coded uniform resource locator (URL) stored by the device;
- obtaining, from a first network element, a request for a virtual private network service along a path associated with one or more network elements of the plurality of network elements, wherein the first network element is a network function;
- responsive to the request, analyzing the first information associated with the plurality of network elements to determine whether the one or more network elements meet each of a plurality of thresholds within the request for the virtual private network service along the path associated with the one or more network elements of the plurality of network elements,
- wherein the plurality of thresholds comprise a maximum central processing unit (CPU) utilization and utilization of an interface;
- and
- wherein the plurality of network elements comprise a provider edge or a virtual private network gateway;
- in response to the analyzing, selecting a second network element of the plurality of network elements that meets the plurality of thresholds;
- and
- providing instructions to at least the first network element,
- wherein the instructions cause the creation of a virtual private network tunnel between the first network element and the second network element.

A method performed by a device, the method comprising:
- receiving first information from a plurality of network elements, wherein the first information comprises bandwidth of interfaces, central processing unit (CPU) utilization, and utilization of interfaces, wherein the first information is obtained with use of a hard-coded uniform resource locator (URL) stored by the device;
- obtaining from a first network element, a request for a new virtual private network service along a path associated with one or more network elements of the plurality of network elements, wherein the first network element is a network function;
- responsive to the request, analyzing the first information associated with the plurality of network elements to determine whether the one or more network elements meet each of a plurality of thresholds within the request for the new virtual private network service along the path associated with the one or more network elements of the plurality of network elements;
- wherein the plurality of thresholds comprise a maximum central processing unit (CPU) utilization or utilization of an interface;
- and
- wherein the plurality of network elements comprise a provider edge or a virtual private network gateway;
- in response to the analyzing, selecting a second network element of the plurality of network elements that meets the plurality of thresholds;
- and
- providing instructions to at least the first network element,
- wherein the instructions cause the creation of a new virtual private network tunnel between the first network element and the second network element.

A computer readable storage medium storing computer executable instructions that when executed by a computing device cause said computing device to effectuate operations comprising:
- receiving first information from a plurality of network elements, wherein the first information comprises bandwidth of interfaces, central processing unit (CPU) utilization, and utilization of interfaces, wherein the first information is obtained with use of a hard-coded uniform resource locator (URL) stored by the device;
- obtaining, from a first network element, a request for a virtual private network service along a path associated with one or more network elements of the plurality of network elements, wherein the first network element is a virtual network function;
- responsive to the request, analyzing the first information associated with the plurality of network elements to determine whether the one or more network elements meet each of a plurality of thresholds within the request for the virtual private network service along the path associated with the one or more network elements of the plurality of network elements,
- wherein the each of a plurality of thresholds comprise a maximum central processing unit (CPU) utilization and utilization of an interface;
- and
- wherein the plurality of network elements comprise a provider edge or a virtual private network gateway;
- in response to the analyzing, selecting a second network element of the plurality of network elements that meets the one or more thresholds;
- and
- providing instructions to at least the first network element,
- wherein the instructions cause the creation of a virtual private network tunnel between the first network element and the second network element.
