Method for network slice isolation management
A method for network isolation management is described. The method includes assigning or creating one or more isolation groups for at least one service, wherein resources of services assigned in an isolation group are shared with or without isolation; wherein an isolation group is defined for at least one resource in each layer and each domain to gather the at least one resource of the at least one service; linking an isolation profile for each of the one or more isolation groups, wherein the isolation profile comprises at least one policy to protect the at least one resource of the one or more isolation groups, and wherein the isolation profile comprises at least an isolation level to define a type of isolation; and allocating or reallocating the at least one resource to the at least one service based on the isolation profile linked to the one or more isolation groups.
1. A method comprising:
assigning or creating one or more isolation groups for at least one service, wherein resources of services assigned in an isolation group are shared with or without isolation;
wherein an isolation group is defined for at least one resource in each layer and each domain to gather the at least one resource of the at least one service;
linking an isolation profile for each of the one or more isolation groups, wherein the isolation profile comprises at least one policy to protect the at least one resource of the one or more isolation groups, and wherein the isolation profile comprises at least an isolation level to define a type of isolation;
allocating or reallocating the at least one resource to the at least one service based on the isolation profile linked to the one or more isolation groups;
wherein the one or more isolation groups is a root isolation group, or the one or more isolation groups is contained by another isolation group; and
further comprising determining an isolation for the at least one resource of one service by checking an isolation profile of a containing isolation group until all isolation groups in a chain of containing isolation groups, including the root isolation group, are addressed or considered.
2. The method of claim 1 , wherein the isolation group is defined based on a type of the at least one resource, and characteristics of services supported by the at least one resource.
3. The method of claim 1 , wherein resources allocated to service are physically or logically isolated from resources of other services assigned in different isolation groups, based on the isolation profile.
4. The method of claim 1 , wherein the one or more isolation groups are assigned or created by a service consumer or service producer.
5. The method of claim 1 , wherein the isolation level is either physical or logical isolation.
6. The method of claim 1 , wherein the isolation profile is associated with a service profile of a supported service, or is independent.
7. The method of claim 1 , wherein the at least one resource is a management resource, and the at least one resource is a managed resource.
8. The method of claim 1 , wherein an isolation level of the containing isolation group is stricter than an isolation level of the contained isolation group.
9. The method of claim 1 , further comprising determining an isolation for the at least one service by checking an isolation profile of a linked isolation group until a plurality of resource types are addressed.
10. The method of claim 1 ,
wherein the resources of services assigned in an isolation group are shared without isolation when the resources of the services are assigned in a common isolation group; and
wherein the resources of services assigned in an isolation group are shared with isolation when the resources of the services are further assigned in different isolation groups inside the common isolation group.
