Objectives

Explain the different architectural components of the NetAct system

Explain the concept of regional and global cluster and how it is implemented with the hardware

List typical cluster/hardware scenarios with their capacity statements

Understand the idea and implementation of the open architecture of the NetAct system

List principles and components of a DCN network for O&M used in technology independent network management

NetAct OSS5.1 Platform

• NetAct releases from OSS5.1 onwards will be running on Linux operating system on top of x86 compatible server platforms

• The new platform enables easier maintainability of NetAct clusters (less systems to maintain) thus providing savings in System Administration

• NetAct clusters continue the evolution from a single compact functional entity into scalable cluster with data-storage and application server functionality separated

• The computing platform is designed to allow the latest technologies within the server, storage and operating system space to be adapted quickly and transparently

Upgrade to NetAct OSS5.1


Compatibility of NetAct OSS5.1 Release

NetAct OSS5.1 provides Management Functionality, for example, for the following network element releases:

– RAS06– BSS13 – MGW U4.0 – MSS M14.0 – SG6 CD4 – WiMAX WMR1.0&1.1 – I-HSPA rel 1 – CM for M14 – CM for U4.0

Support for RU10!See the NetAct compatibility documentation for more detailed information.

Security Solution

Security threat and risk analyses in OS has been done

• Attack routes and targets, assets evaluation, impacts and consequences of the events

Security enhancements is OSS4 allow that Nokia NetAct can be operated according to reasonable security policies

• Protection against commonly known threats in normal network management operations

Security is like a quality, must be taken into account in all product development phases and in normal system administration and operation

NetworkNetwork• Firewall & VPN management• Encrypting the business sensitive data

SystemSystem• Operating system hardening Linux, HP-UX, Windows200(3)• Audit Trail (log mgmt)• Security check scripts

UserUser• Authentication • Authorization• User account management
