2. At a glance
req from draft-ietf-pce-discovery-reqs-05.txt & spec from draft-ietf-pce-disco-proto-igp-02.txt
pcedpPccDiscoveryObjects:
A control to disable automatic discovery by the PCC: Done;
Number of known PCEs: Done, Number of discovered PCEs: Done.
Set of known PCEs: Done pcedpPccDiscTable :
IPv4 and IPv6 adresses (PCE-ADDRESS): Done;
Time since the PCE was discovered and any change to the discovered information : Done;
TODO: When a PCE is no longer alive, it SHOULD no longer be reported
? Use some hysteresis monitored by some activity objects ?
pcedpPccPceCapabilityObjects
For each PCE
PCE-DOMAINS and PCE-DEST-DOMAINS Done in pccPcedpCapDomainTable & pccPcedpCapDestDomainTable
PATH-SCOPE Done: pcedpPccPceCapScopeTable (6 comp scope + 4 pref fields )
PATH-COMP-CAPS (TODO) & CONGESTION (Done)
Information locally configured about the PCE Done? pccPcedpDiscMechanism == local;
TODO pcedpPccPceActivityObjects
Provide the average and maximum rates of arrival, departure and modification of PCE discovery to enable effective analysis of the operation of the protocols.
Report on the operation of the discovery protocol by counting the number of unacceptable and incomprehensible information exchanges.
TODO pcedpPccNotifications
Notifications when thresholds (e.g. on the maximum rate of change, on the number of unacceptable messages) are crossed, or when important events occur (e.g. the number of discovered PCEs decreases to zero).
