This feature/bug is related to bug #1450617 (Neutron extension to support service chaining)
Bug #1450617 is to add a neutron port chaining API and associated "neutron port chain manager" to support service chaining functionality. Between the "neutron port manager" and the underlying service chain drivers, a common service chain driver API shim layer is needed to allow for different types of service chain drivers (eg. OVS driver, different SDN Controller drivers) to be integrated into the Neutron. Different service chain drivers may have different ways of constructing the service chain path and use different data path encapsulation and transport to steer the flow through the chain path. With one common interface between the Neutron service chain manager and various vendor-specific drivers, the driver design/implementation can be changed without changing the Neutron Service Chain Manager and the interface APIs.
This interface should include the following entities:
* An ordered list of service function instance clusters. Each service instance cluster represents a group of like service function instances which can be used for load distribution.
* Traffic flow classification rules: It consists of a set of flow descriptors.
Usually new features are tracked via blueprints, not bugs, and require spec to be merged.
