Title:
common service chaining driver API
Status in OpenStack Neutron (virtual network service):
Opinion
Bug description:
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.
