Method for network slice isolation management

An apparatus comprising:

• at least one processor;
• and
• at least one non-transitory memory including computer program code;
• wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to perform:
• assign or create 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;
• link 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
• allocate or reallocate the at least one resource to the at least one service based on the isolation profile linked to the one or more isolation groups.

A non-transitory program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for performing operations, the operations 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 at the 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.
