Class BasicPceccHandler

java.lang.Object

org.onosproject.pcep.controller.impl.BasicPceccHandler

public final class BasicPceccHandler
extends Object

Basic PCECC handler. In Basic PCECC, after path computation will configure IN and OUT label to nodes. [X]OUT---link----IN[Y]OUT---link-----IN[Z] where X, Y and Z are nodes. For generating labels, will go thorough links in the path from Egress to Ingress. In each link, will take label from destination node local pool as IN label, and assign this label as OUT label to source node.
