java.lang.Object

es.tid.rsvp.messages.RSVPMessage

es.tid.rsvp.messages.RSVPPathErrMessage

All Implemented Interfaces:

RSVPElement

public class RSVPPathErrMessage
extends RSVPMessage

Braden, Ed., et. al. Standards Track [Page 43] RFC 2205 RSVP September 1997 3.1.7 Path Error Messages PathErr (path error) messages report errors in processing Path messages. They are travel upstream towards senders and are routed hop-by-hop using the path state. At each hop, the IP destination address is the unicast address of a previous hop. PathErr messages do not modify the state of any node through which they pass; they are only reported to the sender application. ::= [ ] [ ...] [ ] ::= (see earlier definition) The ERROR_SPEC object specifies the error and includes the IP address of the node that detected the error (Error Node Address). One or more POLICY_DATA objects may be included message to provide relevant information. The sender descriptor is copied from the message in error. The object order requirements are as given earlier for a Path message, but the above order is recommended.
