Abstract

In one embodiment, a method comprises receiving a request for a distributed service, the distributed service offered by a service provider via a data communications network having service delivery locations reachable via a prescribed physical topology; identifying the service delivery locations within a prescribed logical topology overlying the prescribed physical topology, the prescribed logical topology segregating the distributed service from other network traffic on the prescribed physical topology; and identifying one or moreof the service delivery locations optimized for providing the distributed service to at least one service consumption location in the prescribed logical topology according to a prescribed service level agreement with the service provider.

2. The method of claim 1, wherein:

the identifying of the service delivery locations within the prescribed logical topology includes identifying logical endpoints within the prescribed logical topology, and identifying, from among the logical endpoints, first logical endpoints for placement of the service delivery locations, and at least one second logical endpoint for placement of the at least one service consumption location;

the identifying the one or more service delivery locations as optimized for providing the distributed service including generating an ordered list of the service delivery locations based on ranking the service delivery locations at the respective first logical endpoints relative to the at least one second logical endpoint of the at least one service consumption location, based on the prescribed service level agreement.

3. The method of claim 1, wherein the identification of the service delivery locations within the prescribed logical topology is based on any one of:

a label distribution protocol implemented within the prescribed logical topology according to a prescribed multiprotocol label switching (MPLS) protocol,

identification of a common virtual local area network (VLAN) identifier within the prescribed logical topology implementing the prescribed logical topology according to virtual Private LAN service (VPLS), or

a prescribed protocol for transporting link layer packets over an Internet Protocol (IP)/MPLS backbone.

4. The method of claim 1, wherein the prescribed logical topology establishes a private network offered by the service provider to multiple users utilizing the distributed service according to the prescribed service level agreement, the prescribed logical topology providing link layer based multipoint layer 2 virtual private network (VPN) service between the service delivery locations and the at least one service consumption location.

5. The method of claim 1, wherein the identifying the one or more service delivery locations as optimized includes providing an ordered list of the service delivery locations, the ordered list providing a ranking of the service delivery locations relative to the at least one service consumption location, the ordered list specifying, for each service delivery location, an aggregated score representing a relative optimal placement of the corresponding service delivery location relative to the at least one service consumption location.

6. The method of claim 5, wherein the aggregated score for each service delivery location is based on aggregating proximity results for a plurality of the service consumption locations, the aggregating of the proximity results based on weighting virtual path parameters between each service delivery location and each service consumption location with service-level agreement attributes, and aggregating the weighted virtual path parameters for each service delivery location across the service consumption locations.

7. The method of claim 1, wherein the distributed service is a cloud computing service.

8. An apparatus comprising:

a network interface circuit configured for receiving a request for a distributed service, the distributed service offered by a service provider via a data communications network having service delivery locations reachable via a prescribed physical topology; and

a processor circuit configured for identifying the service delivery locations within a prescribed logical topology overlying the prescribed physical topology, the prescribed logical topology segregating the distributed service from other network traffic on the prescribed physical topology;
