Class ErrorFlowDescriptor

java.lang.Object

es.tid.rsvp.constructs.RSVPConstruct

es.tid.rsvp.constructs.ErrorFlowDescriptor

All Implemented Interfaces:

RSVPElement

Direct Known Subclasses:

FFErrorFlowDescriptor, SEErrorFlowDescriptor, WFErrorFlowDescriptor

public class ErrorFlowDescriptor
extends RSVPConstruct

Represents a Error Flow Descriptor construct, as defined in RFC 2205.

The following style-dependent rules define the composition of a valid error flow descriptor; the object order requirements are as given earlier for flow descriptor.

• WF Style: <error flow descriptor> ::= <WF flow descriptor>
• FF style: <error flow descriptor> ::= <FF flow descriptor>

  Each flow descriptor in a FF-style Resv message must be processed independently, and a separate ResvErr message must be generated for each one that is in error.

• SE style: <error flow descriptor> ::= <SE flow descriptor>

  An SE-style ResvErr message may list the subset of the filter specs in the corresponding Resv message to which the error applies.

Note that a ResvErr message contains only one flow descriptor. Therefore, a Resv message that contains N > 1 flow descriptors (FF style) may create up to N separate ResvErr messages.
