  2. 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

  3. 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.

  4. 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

  5. PRABANDH-NMS architecture Level 0 PRABANDH- NMS Level 1 PRABANDH- PRABANDH- NMS NMS Level 2 PRABANDH- PRABANDH- PRABANDH- NMS NMS NMS Network et al. Router Switch Firewall Server Devices

  6. PRABANDH-NMS modules Security Discovery management Performance Log management management Fault Resource management management Configuration User interface management Accounting PRABAN Help Desk management DH-NMS

  7. 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 of 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

  8. 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

  9. PRABANDH Pluggable Encryption Module (Secure communication between Prabandh Servers) PRABANDH Server 1 PRABANDH Server 2 Encryption/Decryption Encryption/Decryption Module 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

  10. DR architecture design PRABANDH-NMS PRABANDH-NMS Top level Top level DR site DB DB 1. In two level deployment scenario the level 1 PRABANDH-NMS PRABANDH-NMS Level 1 NMS will collect data from network devices 2. The level 1 NMSs will push the aggregated/summarized data to top level NMS over secure link. Device 1 Device N ….. 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.

  11. 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
