Technical Challenges
There are more challenges in this implementation
But
All challenges of a multi-vendor, multi-technology, multi-product
implementation exist here
Technical Challenges
Multi networks working with private addresses
Presenting partitioned information to the Nortel end customer
Moving from technology-centric to customer-centric view
Migration from 16 systems to 1
Flexibility – each customer wants it “his way”
Network Address Translation (NAT)
The challenge:
Most of the Nortel customers are working with private addresses (10.10 and or 192.68)
All events sent to the same server
The solution:
Perform NAT at every customer site in order to provide a unique IP address that would be recognized by the system
The original IP address is also kept and this is the IP presented to the Nortel end customer

Partitioning
The challenge:
Nortel Users are not authorized to see the networks
of ALL customers
Customer themselves are authorized to see their own
networks only
The solution:
Partition the underlying inventory

Partitioning – the basis for service management
First layer of partitioning is per serviceMonitoring is per service
Next layer is per customerSLAs per service per customerCustomers want a view into their own networkIn the near future – customers may initiate an automatic provisioning process
System flexibility
The challenge:
Every Service Provider wants full flexibility
Nortel needed more!
The solution:
TTI’s solution is extremely flexible and easily adaptable
Mediation layer normalizes the information – other products must not be changed
Common methodology to all domains
Eliminates need for extensive user training
Nortel personnel can define new “libraries” fast, on their own
Migration from 16 systems to 1
The Challenge:
Zero down-time
Smooth migration
The Solution:
Well-defined migration procedures
Excellent cooperation between the Nortel and TTI professionals – tightly aligned partnership with joint objectives
