Abstract

Disclosed is a system and method of providing transport-level identification and isolation of container traffic. The method includes assigning, by a software-defined-network (SDN) controller in an SDN-enable cloud environment, a service-ID to a service, a tenant-ID to a tenant and/or workload-ID to yield universal cloud classification details, and extracting, from a data flow, the universal cloud classification details. The method includes receiving a policy, generating flow rules based on the policy and universal cloud classification details, and transmitting the flow rules to an openflow application to confine packet forwarding decisions for the data flow.

Claims

1. A method comprising:

assigning, by a software defined network controller in a software-defined network-enable cloud environment, a service-ID to a service and a tenant-ID to a tenant, to yield universal cloud classification details;

extracting, from a data flow, the universal cloud classification details;

generating flow rules based on a received policy and universal cloud classification details; and

transmitting the flow rules to an application to confine packet forwarding decisions for the data flow.

2. The method of claim 1, further comprising storing the service-ID and tenant-ID.

3. The method of claim 1, wherein the universal cloud classification details are stored in header of a packet in the data flow.

4. The method of claim 1, wherein the flow rules are defined using a 5-tuple classification.

5. The method of claim 1, wherein the flow rules are defined without direct understanding of the service-ID or the tenant-ID.

6. The method of claim 1, wherein the software defined network controller communicates via an API.

7. The method of claim 1, wherein the policy is based on the service-ID and the tenant-ID.

8. The method of claim 1, wherein the policy is defined on one of a per service-ID basis and per tenant-ID basis.

9. The method of claim 1, wherein the extracting comprises extracting the universal cloud classification details at one of an openflow application and a universal cloud classification as a service component.

10. The method of claim 1, wherein a controller module in the software-defined network-enable cloud environment assigns the service-ID to the service and the tenant-ID to the tenant.

11. The method of claim 1, further comprising assigning a workload-ID to workload of the tenant, wherein the universal cloud classification details comprise the service-ID, the tenant-ID and the workload-ID.

12. The method of claim 11, further comprising generating the flow rules based on the universal cloud classification details.

13. A system comprising:

one or more processors; and

a computer-readable medium, storing instructions which, when executed by the one or more processors, cause the one or more processors to perform operations comprising;

assigning, by a software-defined network controller in a software-defined network-enable cloud environment, a service-ID to a service and a tenant-ID to a tenant to yield universal cloud classification details;

extracting, at a switch and from a data flow, the universal cloud classification details;

receiving a policy;

generating flow rules based on the policy and universal cloud classification details; and

transmitting the flow rules to an application to confine packet forwarding decisions for the data flow.

14. The system of claim 13, wherein the flow rules are defined using a 5-tuple classification.

15. The system of claim 13, wherein the universal cloud classification details are stored in header of a packet in the data flow.

16. The system of claim 13, wherein the software-defined network controller communicates via an API.

17. The system of claim 13, wherein the policy is based on the service-ID and the tenant-ID.

18. The system of claim 13, wherein the policy is defined on one of a per service-ID basis and per tenant-ID basis.

19. The system of claim 13, wherein the computer-readable medium stores additional instructions which, when executed by the processor, cause the processor to perform further operations comprising assigning a workload-ID to workload of the tenant, wherein the universal cloud classification details comprise the service-ID, the tenant-ID and the workload-ID.

20. A computer-readable storage device storing instructions which, when executed by a processor, cause the processor to perform operations comprising:

assigning, by a software-defined network controller in a software-defined network-enable cloud environment, a service-ID to a service and a tenant-ID to a tenant to yield universal cloud classification details;

extracting, at a switch and from a data flow, the universal cloud classification details;

receiving a policy;

generating flow rules based on the policy and universal cloud classification details; and

transmitting the flow rules to an application to confine packet forwarding decisions for the data flow.
