Abstract
A method (400) for providing support for elasticity within a domain of a multi-domain network. The method comprises receiving (401) information for a requested virtual link forming part of an end-to-end path across the multi-domain network; wherein the information of the virtual link comprises a service parameter and an elasticity parameter. The method further comprises selecting (402) a physical path (150) corresponding to the virtual link on which to send traffic. The physical path is selected based on a service parameter and an elasticity parameter of the physical path.
Claims16
A method for providing support for elasticity within a domain of a multi-domain network, the method comprising:
- receiving information for a requested virtual link forming part of an end-to-end path across the multi-domain network;
- wherein the information of the virtual link comprises a service parameter and an elasticity parameter, and
- selecting a physical path corresponding to the virtual link on which to send traffic, wherein the physical path is selected based on a service parameter and an elasticity parameter of the physical path.
The method as claimed in cliam 1 comprising determining if a request for a virtual link comprising the requested service parameter satisfies a service parameter of a virtual link in a domain, or determining if the request for the virtual link comprising the requested service parameter satisfies the combination of the service parameter and a elasticity parameter of the virtual link in the domain.
A Virtualizer configured to:
- receive information for a virtual link forming part of an end-to-end path across the multi-domain network;
- wherein the information of the requested virtual link comprises a requested service parameter and a requested elasticity parameter, and
- select a physical path corresponding to the virtual link on which to send traffic,
- wherein the Virtualizer is configured to select the physical path based on a service parameter and an elasticity parameter of the physical path.
An apparatus comprising an Orchestrator, a Virtualizer and a Path Calculation Element, the apparatus comprising:
- an interface configured to receive information for a virtual link forming part of an end-to-end path across a multi-domain network;
- wherein the information of the virtual link comprises a requested service parameter and a requested elasticity parameter, and
- the Virtualizer is configured to select a physical path corresponding to the virtual link on which to send traffic, wherein the physical path is selected based on a service parameter and an elasticity parameter of the physical path.
