Class SffGraph

java.lang.Object

org.opendaylight.sfc.ofrenderer.processors.SffGraph

public class SffGraph
extends Object

This class stores a simple Connection Graph of how the SFFs (Service Function Forwarders) are interconnected. Additionally, it stores SFF ingress and egress DPLs (Data Plane Locators) for a particular PathId

isUsingLogicalSFF

public boolean isUsingLogicalSFF()

Return whether the rendered service path that the graph models is using a logical SFF. Note: this is only one very simple one among possible implementations (e.g. other one would be to check that the chain is using SFF's without any data plane locator).

Returns:

whether the RSP modeled by this graph is using a logical SFF
