A Path Computation Element (PCE) may be required to perform
dependent path computations.  Dependent path computations are
requests that need to be synchronized in order to meet specific
objectives.  An example of a dependent request would be a PCE
computing a set of services that are required to be diverse
(disjointed) from each other.  When a PCE computes sets of dependent
path computation requests concurrently, use of the Synchronization
VECtor (SVEC) list is required for association among the sets of
dependent path computation requests.  The SVEC object is optional and
carried within the Path Computation Element Communication Protocol
(PCEP) PCRequest (PCReq) message.

This document does not specify the PCEP SVEC object or procedure.
This informational document clarifies the use of the SVEC list for
synchronized path computations when computing dependent requests.
The document also describes a number of usage scenarios for SVEC
lists within single-domain and multi-domain environments.  
This document is not an Internet Standards Track specification; it is
published for informational purposes.

This document is a product of the Path Computation Element Working Group of the IETF.
