21/22 January, 2016 NKN Workshop, Hyderabad PRABANDH-NMS PRABANDH-NMS Pervasive Resilient Accountable Bhartiya National Distributed Hierarchical -Network Management System
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 architecture Level 0 PRABANDH- NMS Level 1 PRABANDH- NMS PRABANDH- NMS Level 2 PRABANDH- NMS PRABANDH- NMS PRABANDH- NMS Network Devices Router Switch Firewall Server et al.
PRABANDH-NMS modules Security management Discovery Performance management Log management Fault management Resource management Configuration management User interface Accounting management PRABAN DH-NMS Help Desk
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
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 Encryption/Decryption Encryption/Decryption PRABANDH Server 2 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
DR architecture design PRABANDH-NMS PRABANDH-NMS Top level DB DB Top level DR site Level 1 PRABANDH-NMS PRABANDH-NMS Device 1.. Device N 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 over 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
