public class P2MPEndPointsIPv4
extends EndPoints

PCEP P2MPEND-POINTS object.

Represents a PCEP P2MPEND-POINTS object IPv4 Type, as defined in RFC 6006

From RFC 6006 Section 3.3.2 END-POINTS Object

 The END-POINTS object is used in a PCReq message to specify the
   source IP address and the destination IP address of the path for
   which a path computation is requested.  To represent the end points
   for a P2MP path efficiently, we define two new types of END-POINTS
   objects for the P2MP path:

   o  Old leaves whose path can be modified/reoptimized;

   o  Old leaves whose path must be left unchanged.

   With the new END-POINTS object, the PCE path computation request
   message is expanded in a way that allows a single request message to
   list multiple destinations.

   In total, there are now 4 possible types of leaves in a P2MP request:

   o  New leaves to add (leaf type = 1)

   o  Old leaves to remove (leaf type = 2)

   o  Old leaves whose path can be modified/reoptimized (leaf type = 3)

   o  Old leaves whose path must be left unchanged (leaf type = 4)

   A given END-POINTS object gathers the leaves of a given type.  The
   type of leaf in a given END-POINTS object is identified by the END-
   POINTS object leaf type field.

   Using the new END-POINTS object, the END-POINTS portion of a request
   message for the multiple destinations can be reduced by up to 50% for
   a P2MP path where a single source address has a very large number of
   destinations.
