- Construction of Higher Capacity Backbone Transport networks for transportation and routing of IP packet of various ICT services at different cities under Dhaka, Chittagong, Khulna, Rajshahi,Rangpur, Barisal & Sylhet divisions.
- Construction of Access networks for various IP based ICT services at different cities under Dhaka, Chittagong, Khulna, Rajshahi, Rangpur, Barisal & Sylhet divisions.
- Contribute to build up Digital Bangladesh through building the necessary infrastructure for various IP based ICT services.
Major Scope of Works,
i) IP Backbone
- Construction of IP backbone network connecting various important cities of Bangladesh. Total 62 IP PoPs has been constructed.
- Construction of a high capacity optical transport network, as IP based services are bandwidth hungry. Total 49 Transmission nodes (DWDM & MSPP) has been installed out of which 39 in phase-I.
- Construction of nearly 1450 km optical transmission networks for connecting Khulna, Barisal and Sylhet Divisional cities and some important district cities. Out of which 300 km in EDCF loan and rest are in GoB fund.
ii) Access Networks.
- PON based optical Access networks is being built in 4 exchanges (Moghbazar, Central, Gulshan and SB Nagar) of Dhaka city
- ADSL based Access networks for about 24,000 subscribers in 74 nodes has been built for rendering ADSL service over the existing copper cable networks in 32 districts and 4 upazilas.
- Besides, it will be possible to provide IP bandwidth directly from the PoPs for medium and big subscribers through IP switch.
- More than 100 km optical access network has also been constructed to connect different government offices, educational institutions and important locations.
Network Design :
INFO-BAHAN project applies the IP/MPLS technology as a national data backbone network for the benefits of IP/MPLS as follows;
- MPLS is a high-performance packet forwarding technology that integrates the performance and traffic management capabilities of data link layer (Layer-2) switching with the scalability, flexibility and performance of network-layer (Layer-3) routing.
- Next generation IP backbone network services such as all IP and BcN network service are based on IP/MPLS technology.
- MPLS enables service providers to meet challenges brought about b explosive growth and provides the opportunity for differentiated services without necessitating the sacrifice of existing infrastructure.
- MPLS blends the intelligence of routing with the performance of switching, enabling service providers to extend the capabilities of IP to large-scale VPN implementations. So, using MPLS, VPNs have become much easier to deploy and scale.
