Solutions for low-bandwidth information provision
When providing Internet in areas with low availability or high costs the focus is on getting as much information as possible through a thin (or bandwidth limited link). Examples of such low availability links are satellite links and congested mobile networks.
Basic Internet provides solutions which optimise the information stream such that a high amount of information can be provided. This information optimization is done in the Basic Internet Core Network or through technologies of our partners, with Opera Mini being the best example of a browser providing a maximum of information given limited capacity in the network.
Our infrastructure contains of the Basic Internet central AAA server located in Kjeller, Norway, and the Basic Internet Customer Equipment located in the customer network, as indicated in the figure below.
Our distributed architecture opens for a quick deployment of a cost-effective Internet distribution worldwide, allowing for
- Free configurable provision of educational, informational and global content.
- Our aim of free basic access requires as little as 4.5 MByte per user and month, which is about the size of one .mp3 music file.
- A high-bandwidth local distribution network supporting local collaboration and content distribution
- The optional server can be preloaded with education, health or other information, which can be made freely available for everyone
- A business option for providing full Internet
- Through the provision of free Basic Internet we'll promote the individual development, aiming at everyone being able to participate in the Global IT-driven economy. Full business access is part of the Basic Internet solution through the sales of vouchers for full access to the Internet.
Extending the Basic Internet Network
note on use of ASA: each simple router will do the job, need to be adapted based on the capacity to handle
Option 1: DHCP for each sub-network
Provide each University (or even parts of a University) with an own sub-network.
- Requires a path from Mikrotik to one ASA
ASA providing different DHCP, f. eks. 172.16.x.x for University A, and 172.16.x.x for University B
- class B: 172.16.x.x (16 bit for networks, 16 bits for end network - max 65000 users per network)
- example: need for 5.000 IP addresses = 13 bits for end users, rest for network (20.000 students, 5.000 every day)
- class A: 10.x.y.z/8 - 8 bit for the network, 24 bits for the end users (> 2million end users)
- class C: 192.168.1.x/24 - 24 bits for network, and 8 bits for end devices (255 devices)
- new: supports also classless...
Option 2: Tunnel from each ASA
Central infrastructure with one ASA
- each site has an own ASA providing DHCP
- on-site ASA has a VPN back to the central ASA
