o 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 ?

o 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;

o 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. o 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).

MIB Objects

o PCE (Discovery) Objects• pccPcedpDiscPceTable (to be renamed

pccPcedpPceTable)• PCE-ADDRESS IE & soon CONGESTION IE

o PCE Capability Objects• pccPcedpCapPathScopeTable: PATHSCOPE IE• pccPcedpCapDomainTable: PCE-DOMAINS IE• PccPcedpCapDestDomainTable: PCE-DEST-DOMAINS IE• PATH-COMP-CAPS (in progress)

o PCE Activity Objects ( To be merged with PCE Objects)• pccPcedpDiscActTable (will be removed)

• CONGESTION (wrong place: going to pccPcedpPceTable)
