Abstract
Various embodiments relate to a method and apparatus for programmable and dynamic approach for end-to-end multi-domain L2/L3 service placement in telecommunications networks including defining a DSM policy by defining each of a plurality of service realms, assigning a plurality of nodes to the plurality of service realms, assigning service-type flags to each of the plurality of nodes, assigning internetworking flags to at least one of a plurality of internetworking nodes and applying the DSM policy during L2/L3 service creation. The DSM policy also can be defined to include all possible paths between any two endpoints in the context of a service.
Claims28
A method for end-to-end multi-domain service placement in telecommunications networks, comprising:
- defining a service-realm Dynamic Service Model (“DSM”) policy by:
- creating a physical topology of a network;
- defining each of a plurality of service realms in the network;
- assigning a plurality of nodes to the plurality of service realms;
- assigning service-type flags to each of the plurality of nodes;
- and
- assigning internetworking flags to at least one of a plurality of internetworking nodes;
- and
- applying the DSM policy during L2/L3 service creation.
A non-transitory machine-readable storage medium encoded with instructions for end-to-end multi-domain service placement in telecommunications networks, the medium comprising:
- instructions for defining a service-realm Dynamic Service Model (“DSM”) policy by:
- creating a physical topology of a network;
- defining each of a plurality of service realms in the network;
- assigning a plurality of nodes to the plurality of service realms;
- assigning service-type flags to each of the plurality of nodes;
- and
- assigning internetworking flags to at least one of a plurality of internetworking nodes;
- and
- instructions for applying the DSM policy during L2/L3 service creation.
A method for end-to-end multi-domain service placement in telecommunications networks, comprising:
- defining an implicit-service Dynamic Service Model (“DSM”) policy by:
- creating a network topology;
- assigning service-type flags to each of the plurality of nodes;
- assigning inter-networking capability flags to routers in the network topology;
- and
- defining all possible paths between all endpoints, and ’creating the DSM policy which describes all possible paths between all of the endpoints;
- applying the DSM policy during L2/L3 service creation.
