Adaptive network slicing via overlaying decomposition and inheritance
Systems and methods include provisioning a default slice having a default subdomain corresponding to a set of resources that are any of physical and virtual components in a network; decomposing the default subdomain into a first set of one or more subdomains, wherein collectively the first set of one or more subdomains include all of the set of resources; provisioning one or more application slices as children from the default slice that inherit capabilities of the default slice; and assigning one or more subdomains from the first set of the one or more subdomains to the respective one or more application slices.
1. A non-transitory computer-readable medium comprising instructions that, when executed, cause one or more processors to perform the steps of:
provisioning a default slice having a default subdomain corresponding to a set of resources that are any of physical and virtual components in a network;
decomposing the default subdomain into a first set of one or more subdomains, wherein collectively the first set of one or more subdomains include all of the set of resources;
provisioning one or more application slices as children from the default slice that inherit capabilities of the default slice; and
assigning one or more subdomains from the first set of the one or more subdomains to the respective one or more application slices,
wherein the one or more application slices are provisioned by referencing the default slice as a parent and scoping a creation thereof to limits of the parent, wherein the scoping includes a scope that defines accessibility and access to the one or more application slices along with eligibility to be assigned to the one or more application slices, and wherein the scope is limited to no more than a scope of the parent.
2. The non-transitory computer-readable medium of claim 1 , wherein the instructions that, when executed, further cause one or more processors to perform the steps of
performing management of the underlying physical and virtual components utilizing the first set of the one or more subdomains.
3. The non-transitory computer-readable medium of claim 1 , wherein the instructions that, when executed, further cause one or more processors to perform the steps of
decomposing the first set of the one or more subdomains into a second set of the one or more subdomains, wherein collectively the first set and the second set of the one or more subdomains include all of the set of resources.
4. The non-transitory computer-readable medium of claim 3 , wherein the instructions that, when executed, further cause one or more processors to perform the steps of
compressing the second set of the one or more subdomains back into the first set of the one or more subdomains, as a result of a deletion.
5. The non-transitory computer-readable medium of claim 1 , wherein the instructions that, when executed, further cause one or more processors to perform the steps of
maintaining a Group Access Object for each of the default slice and the one or more application slices to define authority of tenants for each of the default slice and the one or more application slices.
6. The non-transitory computer-readable medium of claim 1 , wherein the instructions that, when executed, further cause one or more processors to perform the steps of
deleting an application slice of the one or more application slices by an owner and addressing any subdomains contained therein.
7. The non-transitory computer-readable medium of claim 1 , wherein the one or more application slices each initially inherit constraints and restrictions from the parent and the inherited constraints and restrictions are adjusted accordingly.
8. The non-transitory computer-readable medium of claim 1 , wherein resources in the first set of one or more subdomains are non-overlapping.
9. An apparatus comprising:
one or more processors and memory comprising instructions that, when executed, cause the one or more processors to
provision a default slice having a default subdomain corresponding to a set of resources that are any of physical and virtual components in a network,
decompose the default subdomain into a first set of one or more subdomains, wherein collectively the first set of one or more subdomains include all of the set of resources,
provision one or more application slices as children from the default slice that inherit capabilities of the default slice, and
assign one or more subdomains from the first set of the one or more subdomains to the respective one or more application slices,
wherein the one or more application slices are provisioned by referencing the default slice as a parent and scoping a creation thereof to limits of the parent, wherein the scoping includes a scope that defines accessibility and access to the one or more application slices along with eligibility to be assigned to the one or more application slices, and wherein the scope is limited no more than a scope of the parent.
10. The apparatus of claim 9 , wherein the instructions that, when executed, further cause the one or more processors to
perform management of the underlying physical and virtual components utilizing the first set of the one or more subdomains.
11. The apparatus of claim 9 , wherein the instructions that, when executed, further cause the one or more processors to
decompose the first set of the one or more subdomains into a second set of the one or more subdomains, wherein collectively the first set and the second set of the one or more subdomains include all of the set of resources.
12. The apparatus of claim 11 , wherein the instructions that, when executed, further cause the one or more processors to
compress the second set of the one or more subdomains back into the first set of the one or more subdomains, as a result of a deletion.
13. The apparatus of claim 9 , wherein the instructions that, when executed, further cause the one or more processors to
maintain a Group Access Object for each of the default slice and the one or more application slices to define authority of tenants for each of the default slice and the one or more application slices.
14. The apparatus of claim 9 , wherein the instructions that, when executed, further cause the one or more processors to
delete an application slice of the one or more application slices by an owner and addressing any subdomains contained therein.
15. The apparatus of claim 9 , wherein the one or more application slices each initially inherit constraints and restrictions from the parent and the inherited constraints and restrictions are adjusted accordingly.
16. The apparatus of claim 9 , wherein resources in the first set of one or more subdomains are non-overlapping.
17. A method comprising:
provisioning a default slice having a default subdomain corresponding to a set of resources that are any of physical and virtual components in a network;
decomposing the default subdomain into a first set of one or more subdomains, wherein collectively the first set of one or more subdomains include all of the set of resources;
provisioning one or more application slices as children from the default slice that inherit capabilities of the default slice; and
assigning one or more subdomains from the first set of the one or more subdomains to the respective one or more application slices,
wherein the one or more application slices are provisioned by referencing the default slice as a parent and scoping a creation thereof to limits of the parent, wherein the scoping includes a scope that defines accessibility and access to the one or more application slices along with eligibility to be assigned to the one or more application slices, and wherein the scope is limited to no more than a scope of the parent.
18. The method of claim 1 , further comprising
performing management of the underlying physical and virtual components utilizing the first set of the one or more subdomains.
