PRABANDH-NMS

Pervasive Resilient Accountable Bhartiya National Distributed Hierarchical -Network Management System

21/22 January, 2016 NKN Workshop, Hyderabad

Introduction

• Network management encompasses activities, methods,

procedures and tools that pertain to operation, administration, maintenance and provisioning of network devices

• Network management is challenging !
• Standards have evolved (far too many like IETF, ITU, ISO, Object

Management Group, Multi Service Switching Forum……)

• BARC & CDAC Collaboration
• Requirement from NKN (for indigenous Network Management

System

Objective

• Develop a generic multilevel hierarchical NMS conforming to

standards in open source platform

• Develop suitable interfaces for the NMS to interact with the

indigenous initiatives such as

The Network security product - Secure Network Access System (SNAS) Integrated Threat Management Appliance, (ITMA), by Electronics Corporation of India Limited (ECIL) and Society for Electronic Transactions and Security (SETS).

• Should support SNMP v1/v2/v3, FCAPS, MPLS Management etc.

Too many standards for comfort !

General view of all standards is that all models should support the following functions : Fault Management Configuration Management Accounting Management Performance Management Security management

PRABANDH-NMS modules

PRABANDH-NMS Functional Modules

• Fault management: Detect, notify and analyze faults encountered

in the network

• Configuration management: Configuration file and software

management

• Accounting management: Collect and analyze usage information of

network resources

• Performance management: Monitor and measure various aspects
• f performance so that overall performance can be maintained at a

defined level

• Security management: Secure access to network devices, network

resources and services to authorized individuals

PRABANDH-NMS Functional Modules continued ..

• Discovery: Discover network devices and topology
• Log management: captures, store and analyze logs generated by

various network devices

• User Interface: Provides an user interface through which user can

manage the whole network.

• Resource Management: Manages resources present in the network
• Help Desk: This module helps network user to log a problem in the

system

PRABANDH Pluggable Encryption Module (Secure communication between Prabandh Servers)

PRABANDH Server 1 PRABANDH Server 2

Encryption/Decryption Module Encryption/Decryption Module

Secure channel

1.This module intercepts message in encrypts/decrypts it before sending to corresponding PRABNDH Server 2.Supports both pre-shared as well as certificate based authentication 3.This is helpful if PRABANDH-NMS in deployed in distributed manner 4.Encryption module can be enabled/disabled using a configuration parameter 5.This module is generic in nature and can be used for other applications as well

…..

• 1. In two level deployment scenario the level 1

NMS will collect data from network devices

• 2. The level 1 NMSs will push the

aggregated/summarized data to top level NMS

• ver secure link.
• 3. In case of any failure in level 1 NMS, the other

NMS at the same level can be configured to collect data from the network devices earlier attached to the failed NMS.

Project Status

• Development is complete
• PRABANDH-NMS has been deployed at several locations
• NTRO-Delhi
• NKN-Thiruvananthapurum
• NKN-Delhi
• NKN-Belapur
• ANUNET-BARC
• University of Kerala
• C-DAC Thiruvananthapurum
