public class Svec
extends PCEPObject

Represents a SVEC Object as defined in RFC 5440

From RFC 5440, Section 7.13.2. SVEC Object

   Section 7.13.1 details the circumstances under which it may be
   desirable and/or required to synchronize a set of path computation
   requests.  The SVEC (Synchronization VECtor) object allows a PCC to
   request the synchronization of a set of dependent or independent path
   computation requests.  The SVEC object is optional and may be carried
   within a PCReq message.

   The aim of the SVEC object carried within a PCReq message is to
   request the synchronization of M path computation requests.  The SVEC
   object is a variable-length object that lists the set of M path
   computation requests that must be synchronized.  Each path
   computation request is uniquely identified by the Request-ID-number
   carried within the respective RP object.  The SVEC object also
   contains a set of flags that specify the synchronization type.

   SVEC Object-Class is 11.

   SVEC Object-Type is 1.

   The format of the SVEC object body is as follows:

    0                   1                   2                   3
    0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

   Reserved (8 bits):  This field MUST be set to zero on transmission
      and MUST be ignored on receipt.

   Flags (24 bits):  Defines the potential dependency between the set of
      path computation requests.

  L (Link diverse) bit: when set, this indicates that the
         computed paths corresponding to the requests specified by the
         following RP objects MUST NOT have any link in common.

  N (Node diverse) bit: when set, this indicates that the
         computed paths corresponding to the requests specified by the
         following RP objects MUST NOT have any node in common.

  S (SRLG diverse) bit: when set, this indicates that the
         computed paths corresponding to the requests specified by the
         following RP objects MUST NOT share any SRLG (Shared Risk Link
         Group).

      In case of a set of M synchronized independent path computation
      requests, the bits L, N, and S are cleared.

   Unassigned flags MUST be set to zero on transmission and MUST be
   ignored on receipt.

   The flags defined above are not exclusive.
