Abstract

A first message that conforms to a first software-defined networking protocol is received from a first source component. A first destination component associated with the first message is identified. A second software-defined networking protocol is determined based, at least in part, on the first destination component. The second software-defined networking protocol is one of a plurality of software-defined networking protocols. A second message that conforms to the second software-defined networking protocol is generated based, at least in part, on the first message. The second message is sent to the first destination component.

First claim

What is claimed is:

1. A method comprising:
based on receipt at a software-defined networking controller of a first message that conforms to a normalized software-defined networking protocol, a software-defined networking interface of the software-defined networking controller identifying a first of a plurality of adapters based on a component type of a first destination component indicated in the first message and metadata of the software-defined networking interface that maps component types to the plurality of adapters, wherein the first destination component is one of a software-defined networking manager or a software-defined networking device that implements a virtualized network function;
the first adapter loading a first of a plurality of message field maps based on a message type of the first message and then transforming the first message into a second message that conforms to a first software-defined networking protocol of a plurality of software-defined networking protocols;
sending the second message to the first destination component;
receiving, at the software-defined networking interface from the first destination component, an indication of a software-defined networking device lifecycle event;
determining that a service manager is registered to receive notifications associated with the software-defined networking device lifecycle event; and
based on determining that the service manager is registered to receive notifications associated with the software-defined networking device lifecycle event, the software-defined networking controller notifying the service manager of the software-defined networking device lifecycle event.

2. The method of claim 1 further comprising:
receiving, by the software-defined networking interface, a third message that conforms to the first software-defined networking protocol;
identifying a service manager component as a destination for the third message, wherein the service manager component communicates according to the normalized software-defined networking protocol;
the first adapter loading a second of the plurality of field maps based, at least in part, on a message type of the third message and metadata indicating the normalized software-defined networking protocol for the service manager component;
the first adapter transforming the third message into a fourth message that conforms to the normalized software-defined networking protocol with the second field map; and
sending the fourth message to the service manager component.

3. The method of claim 1 , wherein transforming the first message into the second message comprises:
generating a message shell, wherein a format of the message shell is based, at least in part, on the first software-defined networking protocol; and
for each of a set of one or more destination message fields indicated in the first field map,
identifying a first source message field in the first message that maps to a first destination message field and extracting a first field value from the first source message field;
inserting the first destination message field into the message shell;
transforming the first field value into a second field value according to an operation defined in the first field map for a mapping of the first source message field to the first destination message field; and
inserting the second field value into the first destination message field.

4. One or more non-transitory machine-readable storage media having program code stored therein, the program code comprising:
software-defined networking interface program code to,
identify which of a plurality of adapter program codes to load based on a component type of a first destination component indicated in a first message based on first metadata that maps component types to adapters, in response to receipt of the first message that conforms to a normalized software-defined networking protocol, wherein the first destination component is one of a software-defined networking manager or a software-defined networking device;
based on receipt from the first destination component of an indication of a software-defined networking device lifecycle event,
determine that a service manager component is registered to receive notifications associated with the software-defined networking device lifecycle event; and
in response to a determination that the service manager component is registered to receive notifications associated with the software-defined networking device lifecycle event, notify the service manager component of the software-defined networking device lifecycle event;

each of the plurality of adapter program codes to,
load one of a plurality of field maps for the adapter program code based on a message type of the first message, one of a plurality of software-defined networking protocols corresponding to the adapter program code, and second metadata that maps message types of the normalized software-defined networking protocol to the plurality of software-defined networking protocols;
transform the first message into a second message based, at least in part, on the loaded one of the plurality of field maps; and

program code to send the second message to the first destination component.

5. A software-defined networking controller comprising:
a processor;
a plurality of network interfaces; and
a machine-readable medium having software-defined networking interface program code and a plurality of adapter program codes, the program codes executable by the processor to cause the software-defined networking controller to,
based on receipt via one of the plurality of network interfaces by an instance of the software-defined networking interface program code of a first message that conforms to a normalized software-defined networking protocol, identify with the instance of the software-defined networking interface which of the plurality of adapter program codes to load based on a component type of a first destination component indicated in the first message based on first metadata that maps component types to adapters, wherein the first destination component is one of a software-defined networking manager or a software-defined networking device that implements a virtualized network function;
with an instance of the identified one of the plurality of adapter program codes,
load one of a plurality of field maps for the identified adapter program code based on a message type of the first message, one of a plurality of software-defined networking protocols corresponding to the identified adapter program code, and second metadata that maps message types of the normalized software-defined networking protocol to the plurality of software-defined networking protocols;
transform the first message into a second message based, at least in part, on the loaded one of the plurality of field maps;

send the second message to the first destination component;
receive, with the instance of the software-defined networking interface program code from the first destination component, an indication of a software-defined networking device lifecycle event;
determine that a service manager component is registered to receive notifications associated with the software-defined networking device lifecycle event; and
in response to a determination that the service manager component is registered to receive notifications associated with the software-defined networking device lifecycle event, notify with the instance of the software-defined networking interface program code the service manager component of the software-defined networking device lifecycle event.

6. The software-defined networking controller of claim 5 , wherein the program codes are further executable by the processor to cause the software-defined networking controller to:
