Campus Wide Networking

Server Room Rack

LAN has been designed with a Full-duplex Gigabit Ethernet backbone offering an aggregate bandwidth of 10 Gbps between different Switches using Single mode fiber. All the switches are linked through OFC

The salient features of campus wide Backbone Network are as follows:

• 10 Gbps Fiber Optic Backbone
• Gigabit Routing Switch
• Three tier architecture - Comprise of Core, distribution and edge switches
• 1/10 Gbps Manageable Switches at Departments capable of layer3 Switching
• UTP CAT 6 Structured Cabling
• There are about 75 switches, which include Extreme, Cisco, Planet, and 3Com products, located in 34 different buildings.
• 1 Gbps connectivity to each client PC
• There are more than 1600 computers connected to this network

The features of campus wide network are as follows:

• Layer 3 intelligence high performance and throughput capacity
• Fault tolerant Supervisory module (MSM) in each core switch
• Hot swappable redundant power supply in Core Switch
• Non-blocking forwarding
• Minimized latency
• Support for QoS, bandwidth tracking, and traffic prioritization
• Voice and wireless connectivity
• Ethernet Automatic Protection Switching (EAPS) resiliency protocol
• Manageable edge switches
• All the switches can be managed from Epicenter (NMS) software
• Monitoring the Campus bandwidth using PRTG and MRTG
• Web Servers are in DMZ. All the users inside and outside the NITT lan can access the Servers in DMZ zone via UTM only
• Support for Virtual Local Area Network (VLAN)
  • Grouping all computers, servers, printers, and resources of a specific department together independent of geographic location of these devices.
  • Improves the security, scalability, and manageability.
• NITT has a 58 Mbps (1:1) leased line Internet connection from Software Technology Park of India (STPi) and 100 Mbps leased line from Bharat Sanchar Nigam Ltd (BSNL) under NME-ICT. Currently work is in progress for providing 1Gbps connectivity as a part of National Knowledge Network (NKN). Network security is provided through two UTM appliances with failover option (Sonic Wall NSA 8500) and two Email Security appliances (Sonic Wall ES8300). User authentication for browsing the Internet is linked with ADS
• Currently Wi-Fi facility is available at Guest House, T&P, Library, Admin block, Lecture Hall Complex. Currently expansion work is going on at Garnet, Zircon, Amber and Opal Hostels to enable students to access Internet from their laptops in Hostels. Wi-Fi facility is also available at Faculty & Staff residence. Network expansion still continues and work in on for making the campus Wi-Fi by deploying more number of Access Points
