Services planned Through Broad band Network
Primary source of Internet bandwidth for retail users for applications such as Web browsing, e-commerce etc.
Multicast video services,video-on-demand etc. through the BRAS.
Allow Wholesale BRAS ports to be assigned to smaller ISPs through the franchisee model wherein the later has a separate network of DSLAMs, AAA, LDAP through a revenue scheme of BSNL.
Dial VPN (VPDN) user connects to NIB-II through the Narrow band RAS and is connected to its private network through a secure L2TP tunnel established between Narrowband RAS and Broadband RAS.
support for both prepaid and postpaid Broad band services.
Components of Broad Band Access Network
Broad band Remote Access Server(BBRAS)
Gigabit and Fast Ethernet Aggregation Switches (LAN Switches).
Digital Subscriber Line Access Multiplexers (DSLAMs)
SS/SSSC (Subscriber Service Selection System/ Centre)
Servers for AAA, LDAP at NOC.
Provisioning and configuration management at NOC.
DSLCPEs
Security Solution
AntiVirus solution : It will provide a mechanism to detect unknown virus.The solution will protect any Gateway and SMTP traffic from virus.
Notification: For mails containing repeated complaints regarding abuse from the same IP address,mail will be sent automatically to the technical contact of the assignee of that IP address.
Network Intrusion detection System: The NIDS will detect unauthorized internal/external intrusion attempts into the data centres of NIB-II and will enable to apply appropriate policies on the firewall so as to prevent such attacks in real time.Suitable alarms will also be sent to the Security Control Console.
Anti Control System: It is provided for Database servers, Messaging Stores, Web-Hosting Servers and NIDS.
Self-protection:Must be able to prevent hackers with root/administrator access from circumventing or shutting down the security engine.
Resource protection :Must allow controlling of access to all system resources including data files, devices, processes/services and audit files.
Rights delegation: Must provide the ability to designate specific users as administrators, auditors and password managers etc with appropriate rights.
Program Controls: Must provide protection against Back Doors and Trojan Horses.
ORDER MANAGEMENT
Work Flow Management will automate the process that controls and monitors the execution of an order according to the customer requirements.This involves the steps of qualification,reservation, configuration and verification of a service fulfilment instance.
Work Flow Management will integrate OM and provisioning Management systems (PMS) being procured under project-1, project –2.2 and Whole-sale Dial Application being procured under project-2.1.
Enterprise Management System
Objective of EMS is to provide a snap-shot graphical view of the health of NIB-II IT infrastructure as a whole including networking equipment ,servers and services (business and process view).
Reporting system will be able to generate customized reports such as event-level, performance -level and service-level reports grouped by specific data fields such as time period, location,customer ,series type,device type etc.
Security Management will display alarm and events specified by the criteria such as alarm type, vendor,service, location, source of attack, type of attack and impacted services.
Event Management will capture all the events that are being generated across the complete IT infrastructure, correlates them and initiate corrective actions automatically, as defined.
System& Application Management will measure the availability and performance of heterogeneous host systems on a 24x7x365 basis and initiate preventive and corrective actions automatically.
System& Application Management will monitor and manage multiple attributes (such as status, memory usage, size and resident size, process time, threads,response time, average throughput and CPU utilization etc) of a running process and problems and perform restart when processes go down. It will generate reports on QOS and capacity planning.
