I2NSF Capability Yang Model
draft-hares-i2nsf-capability-yang-00.txt

[I-D.ietf-i2nsf-problem-and-use-cases] proposes two different types of interfaces:
This document provides a yang models that define the capabilities for security devices that can be utilized by I2NSF NBI between the I2RS network controller and the NSF devices to express the NSF devices capabilities. It can also be used by the IN2SF user application (or I2NSF client) to network controller to provide a complete list of the I2NSF capabilities the Network controller can control.
This document defines a yang data models based on the [I-D.xia-i2nsf-capability-interface-im], and initial work done in [I-D.xia-i2nsf-service-interface-dm]. Terms used in document are defined in [I-D.ietf-i2nsf-terminology].
[I-D.xia-i2nsf-capability-interface-im] defines the following type of functionality in NSFs.
This document contains high-level yang for each type of control. The features in each section have been built up from the following sources:
This section provides an overview of the high level yang.
The high level yang capabilities per NSF device, controller, or application is the following:
ietf-i2nsf-capability
+--rw nsf-capabilities
+--rw capability* [name]
+--rw nsf-name string
+--rw cfg-net-secctl-capabilities
| uses pkt-eca-policy:pkt-eca-policy-set
+--rw cfg-net-sec-content-capabilities
| uses i2nsf-content-caps
| uses i2nsf-content-sec-actions
+--rw cfg-attack-mitigate-capabilities*
| uses i2nsf-mitigate-caps
+--rw ITResource [ITresource-name]
| uses cfg-ITResources
Each of these section mirror sections in: [I-D.xia-i2nsf-capability-interface-im]. The high level yang for cfg-net-secctl-capabilities, cfg-net-sec-content-capabilities, and cfg-attack-mitigate-capabilities. This draft is also utilizes the concepts originated in Basile, Lioy,Pitscheider, and Zhao[2015] concerning conflict resolution, use of external data, and ITResources. The authors are grateful to Cataldo for pointing out this excellent work.
This section defines the network security control capabilites for each NSF entity (device, controller, APP). The portion of the top level model that this explains is the following:
+--rw cfg-net-secctl-capabilities
| uses pkt-eca-policy:pkt-eca-policy-set
Note that yang simply uses the ietf-pkt-eca-policy-cfg from [I-D.ietf-i2rs-pkt-eca-data-model].

The packet-eca policy is kept for configuration, I2RS ephemeral state, and BGP stored policy state in filter-based RIBS. These RIBS have the high-level yang structures below and are described in [I-D.ietf-i2rs-fb-rib-data-model]. These filter-ribs may be leveraged in I2NSF storage devices for the policy storage.
