Case Study: PUST, NSTU and BRU

• Fully running campus

• Located far from City

• Approximate number of Internet users*:• PUST: 2000

• NSTU: 3300

• BRU: 4000

• No internet connection so far

• BTCL is the only hope

• Transmission link is not available

8

Case Study: BU

• Campus under construction


• Approximately 2500 internet users*

• Uses one WiMAX internet connection for official activities

• BTCL is not there yet

• Transmission link is not available



9

Case Study: BSMRSTU, JUST and PSTU

• New and fully running campus

• All are technical universities


• Approximate number of Internet users*:• BSMRSTU: 1500

• JUST: 2400

• PSTU: 1500

• Less than 10 Mbps internet connection

• 8 more similar campuses with ≤10 Mbps BW



10

Challenge: Infrastructure

• Located far from the city

• Areas are not developed

• No transmission infrastructure

• Not lucrative for ISPs, hence little presence

• High BW cost for the Universities


11

Solutions

• Building Transmission infrastructure• Countrywide 3000+ Km, one pair of OPGW from PGCB

• Dedicated OFC for each university• 300+ Km underground OFC for last mile up to universities

• Highly reliable and redundant• Redundant OFC

• DWDM and MPLS based network

• High level Tier-3 DC and DR facilities


12

Challenges: Connectivity and Resources

• No connectivity with R&E networks• Research activity handles high volume of traffic

• Requires low latency/jitter

• No or limited online resource repository

• No or very few facilities for content localization


13

Solutions

• High capacity dedicated academic network connectivity• Connected to TEIN, APAN, Internet2, Geant and so on

• Content localization• Highly equipped large Data Center

• Central/local online repository• Storage of local contents


14

Challenge: Leveraging the services

• No or low maintained campus network

• Poor technical expertise

• Inadequate labs and equipment

• Lack of research and innovation


15

Solutions

• Building high capacity campus network• In each and every public university of Bangladesh

• Training and manpower development• Regular capacity building training and workshops

• Facilitating innovations and preparing highly equipped labs• Fostering academic innovations and research projects

• Research and collaboration through VC and UC systems


16

Challenge: Technical

• Universities doesn’t have own IP and AS

• BdREN has limited IPv4 address

• Necessity of enabling IPv6 network

• Load balancing with other providers


17

Solutions

• Design and deploy dual stack network from day 1

• Planning a scalable network

• Building a highly reliable, robust and redundant network

• Strengthening monitoring system and reducing downtime
