Residence time is the variable part of propagation delay of timing and synchronization messages and knowing what this delay is for each message allows for a more accurate determination of the delay to be @@ -555,22 +555,22 @@ 255.

If the calculated TTL value been set to 255, as described above, then the I flag in node RTM_SET TLV MUST be set to 1 before Resv message forwarded upstream. Otherwise, the I flag MUST be cleared (0). The ingress node MAY inspect the I bit flag received in each RTM_SET TLV contained in the LSP_ATTRIBUTES object of a received Resv message.

An ingress node MAY choose to resignal the LSP to include all RTM nodes or simply notify the user via a management interface. There are scenarios when some information is removed from an RRO due to policy processing (e.g., as may happen between providers) or RRO is limited due to size constraints . Such changes affect the core assumption of the method to control processing of RTM packets. RTM SHOULD NOT be used if it is not guaranteed that RRO contains complete information. @@ -1170,17 +1170,17 @@ Ericsson Email: eric.gray@ericsson.com John Drake Juniper Networks Email: jdrake@juniper.net Stewart Bryant - Cisco Systems + Independent - Email: stbryant@cisco.com + Email: stewart.bryant@gmail.com Alexander Vainshtein ECI Telecom Email: Alexander.Vainshtein@ecitele.com
