DWDM system integration Roundtable Discussion Pieter Hanssens 7 th TF-NOC Poznan

The optical NMS @ Belnet 13,12,2012 DWDM Roundtable 2

Data Flows • Traps are sent by SNMP (pushed) by the NMS (not the node) • Traps are correlated in HPOpenViewSD • Correlation is custom created by 3rd party • Performance data is stored on the nodes • Not pollable by a standard nor a propietary MIB • Workaround implemented: • PM is periodically polled through FTP dd.mm.yyyy Title presentation 3

NMS in the CFT • NOC was chosen at the same time of the procurement of the optical equipment • Integration of Optical monitoring was a scored requirement in the initial CFT of optical equipmeent • Chicken vs Egg problem for non-integrators • Result: integration of the optical equipment into the NOC was the decisive factor for assigning the current NOC • Added benefit: the 2nd-3rd line optical support is the same company as the NOC, no more ping-pong dd.mm.yyyy Title presentation 4

NOC & DWDM systems • 2nd & 3rd line have the same view we have • Incident management is outsourced up until 3rd line • Change management is done by us • Training is not trivial, DWDM is indeed another country (another world is going too far) • Documentation was slightly harder than usual • no concept of backbone links in the CRM • yet another addition to our “CMDB” was needed • impact analysis is done by us, but is easily achieved through the NMS dd.mm.yyyy Title presentation 5

Conclusions • Another party == another layer of delay / documentation / responsibility • The polling mechanism of Layer 2-3 are getting installed into Layer 1 but don’t take this for granted • Documentation and inventory have to be foreseen / harder to integrate afterwards • DWDM world and IP world are slowly integrating. Some technologies can greatly influence the way we think about NMS’es, Optical Change Mgmt, ... • OTN / GMPLS flavors • integration between Layer 3 and Layer 1 (Juniper & Adva) • Others ? dd.mm.yyyy Title presentation 6
