Our NOC's and customers

NOCCustomers

What are customers looking for?

Ability to manage Multi-domain, Multi-technology networks -in one systemAbility to add a new network element fastFlexibility of the system (ability to add reports, views etc.)Flexibility of our services:

From detection only – to full resolutionFrom assurance – to fulfillmentFrom legacy – to converged networks

Manage their own network – have a view of their network and services

Nortel looked for a pre-integrated system with ALL

needed functionality

Reduce Number of Systems

Flexibility and Customization

Ability to Manage Multi-Vendor/Multi-Customer

Standardization of Administrative and Operational Processes

Scalability

Consolidated and Normalized Data Storage

Automation of Routine Tasks

Motivation for moving to one system

Multiple OSS systems delivering operational inefficiencies

>1M per year alone on licenses and infrastructure support

Metric and Reporting being performed manually for both network and operations

Problem Analysis extremely labor intensive requiring elevated skills to perform

Multiple NOC’s globally all operating independently from one another

Unpredictable operating costs

Operational Environment - 5 years ago

Operational Environment - Today

With Netrac in place and running, we have…

1 OSS system (TTI’s Netrac) acting as the primary tool that will be able to support cross domain networks from various product vendors

1 tool set that is capable of delivering all the required service Managed Network Services has to offer

A tool that can be globally distributed

A tool that is flexible enough to change with the ever changing times

A tool that allows MNS to build a legitimate business continuity strategy

Lower capable and predictable operating costs

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
