What is EMS?

• One or more specific type of network element

• Manage of functions and capabilities within NE

• But doesn’t not manage traffic between different NE, for

that it need to report higher level

EMS and four function model

• Service Provisioning

• Service assurance

• EMS and NE operation support

• Automation enabler

EMS architecture requirements

• Correct level of management

• Scalable to grow with the requirements and complexity of

the network

• Supports scalability and availability

How EMS is deployed?

JEE Architecture

Approaches to deploy EMS

• Custom approach

• Development is done in house by the EV or outsourced to the other

company

• Highly customized

• Time consuming

• High cost

Approaches to deploy EMS(Contd.)

• Framework approach

• Additional application layer needs to be added to meet the

individual requirements

• Same look and feel for the different vendors

• Limited customization

• Additional functionality cannot be added

Approaches to deploy EMS(Contd.)

• Components based approach

• Architected from scratch by using pre built components

• Combined approach components and framework approach

• Pre built components

Comparison w.r.t. time

Challenges in deploying EMS for Wireless

Networks

• Managing back up plan

• Manage active and stand by/ back up link

• Tracks the clients. Hence, it helps in network planning

• Handle clients intelligently

• Evaluate the throughput and interference from the other

access point and report it to NMS

NETOP ELEMENT

MANAGEMENT SYSTEM

Redback Networks’

NetOp EMS System Architectures

NetOp EMS multi-server model

NetOp Redundant Server

Intuitive GUI Enables Fast, Effective Management

• Operators can perform fault and security

management for the Redback platforms using the

NetOp EMS software's intuitive GUI.

Superior fault management

Flow Through Service Provisioning

• A Flow Through Service Provisioning CORBA

interface has been implemented in the NetOp.

• This helps the service provider reduce the

following:

• Provisioning Time

• Operation Training

• Operational Errors

CONTD.

• Efficient inventory management

• Configuration Management

• Auto Node Discovery

• Security

• Bulk Operations

Real Time Statistics & Graph Display

Embedded Management

• CLI

• SNMP

• BulkStats

• BGP Attribute-Based Accounting

NetOp Policy Manager functions

• Enforcing policies for

• Metering policies (time-based, duration (byte) based)

• Security policies (eg. Web login)

• Provisioning policies as a result of a subscriber selecting a new service

• Removing policies when a subscriber cancels a service

• Modifying Policies when a subscriber modifies a service

CONTD..

• Maintaining a persistent store of each

subscriber's services and the policies to be

applied for the services

• Proxying RADIUS accounting packets to other

RADIUS servers or billing systems

• Storing accounting data

• Providing centralized authentication

• Enforcing service admission control
