public class MPLSInterfaceInfo

extends ProtocolSession

Class to manage NIC(_NIC)/ONIC/Tunnel Informations.
MPLSInterfaceInfo class provedes MPLS capabilities to the original SSF NIC model.
It can handle several packet format such as IP Packet, Labeled Packet and Optical Frame.
It also provides Queueing and Scheduling functions, resource management functions, packet forwarding functions, and traffic monitoring functions.
Reference : gov.nist.antd.mpls.mgmt.mpls_interface.MPLSInterfaceMgmt.java

  
             The MPLSInterfaceInfo can handle several Queue for servral LSPs..
             The MPLSInterfaceInfo can supports not only a single Scheduler 
             like a Priority, a WFQ and a RoundRobin but alos a hybrid 
             Scheduler like a Priority-WFQ scheduler..
