Abstract

The method of some embodiments allocates a secondary network interface for a pod, which has a primary network interface, in a container network operating on an underlying logical network. The method receives an ND that designates a network segment. The method receives the pod, wherein the pod includes an identifier of the ND. The method then creates a secondary network interface for the pod and connects the secondary network interface to the network segment. In some embodiments, the pods include multiple ND identifiers that each identify a network segment. The method of such embodiments creates multiple secondary network interfaces and attaches the multiple network segments to the multiple secondary network interfaces.

First claim

The invention claimed is:

1. A method of allocating a secondary network interface for a pod with a primary network interface, the method comprising:
receiving a network attachment definition (ND) that designates a first network segment;
receiving a definition of the pod that is being deployed, the pod having the primary network interface passing telecommunication network data and connected to a second network segment of a telecommunication network;
determining that the pod definition includes an identifier of the ND;
creating a secondary network interface for the pod based on the determination that the pod definition includes the identifier of the ND; and
connecting the secondary network interface to the first network segment, said secondary network interface serving as a high-performance interface for data traffic.

2. The method of claim 1 , wherein designating the first network segment comprises identifying a network segment created for a logical network before the ND is received.

3. The method of claim 2 further comprising directing the logical network to modify the network segment according to a set of attributes in the received ND.

4. The method of claim 1 , wherein designating the first network segment comprises providing a set of attributes of the first network segment, the method further comprising, directing a controller to create the first network segment according to the provided set of attributes.

5. The method of claim 4 , wherein the set of attributes comprises a network type, wherein the network type is a VLAN-backed network segment.

6. The method of claim 4 , wherein the set of attributes comprises a network type, wherein the network type is an overlay-backed network segment.

7. A non-transitory machine readable medium storing a program which when executed by at least one processing unit allocates a secondary network interface for a pod with a primary network interface, the program comprising sets of instructions for:
receiving a network attachment definition (ND) that designates a network segment;
receiving a definition of the pod that is being deployed, the pod having the primary network interface;
determining that the pod definition includes an identifier of the ND;
creating a secondary network interface for the pod based on the determination that the pod definition includes the identifier of the ND; and
connecting the secondary network interface to the network segment, said secondary network interface serving as a high-performance interface for data traffic.

8. The non-transitory machine readable medium of claim 7 , wherein the set of instructions for designating the network segment comprises a set of instructions for identifying the network segment created for a logical network before the ND is received.

9. The non-transitory machine readable medium of claim 8 , wherein the program further comprises a set of instructions for directing the logical network to modify the network segment according to a set of attributes in the received ND.

10. The non-transitory machine readable medium of claim 7 , wherein the set of instructions for designating the network segment comprises a set of instructions for providing a set of attributes of the network segment, the program further comprising a set of instructions for directing a controller to create the network segment according to the provided set of attributes.

11. The non-transitory machine readable medium of claim 10 , wherein the set of attributes comprises a network type, wherein the network type is a VLAN-backed network segment.

12. The non-transitory machine readable medium of claim 10 , wherein the set of attributes comprises a network type, wherein the network type is an overlay-backed network segment.
