brief network description
BRIEF NETWORK DESCRIPTION.
  • Mainly TCP/IP Protocol based
  • Servers run on Linux Operating System
  • 3 Subnets initially, now 18 Subnets and 8 cybercafés
  • 2 GB fibre backbone capacity
  • 3 Mbps Spread Spectrum wireless radio linking subnets to main centre, now hybrid of DS and FH systems.
  • Full Internet facilities available on campus.
  • VSAT connectivity with 3.8m, and 2.4m dishes operating at 4.2 GHz and 6.2 GHz in the C band.
ict connectivity
ICT CONNECTIVITY

♣ Mode of ICT Connectivity

Two VSAT with 3.8.m and 2.4 m dishes operating at frequencies in the range of 4.2GHz and 6.2 GHz in the C band.

♣ Internet Bandwidth

-512kbps down/256 kbps up on one VSAT

-256/128 kbps on the backup VSAT.

-Grossly inadequate

-Cost of bandwidth is about $100,000 per year at present capacity.

-Projected bandwidth within next 1 year is 5mbps down/1mbps up .

♣ Estimated up time is over 95%.
