Abstract:
Aim of these projects is to develop a network infrastructure for a private organization
in Bangladesh. One of the major goals of these projects is to implement subnet
concepts to reduce traffic, increase security and extendable network model. Routing
protocol is taking a vital role in the modern communication networks. These projects
presents a simulation based analysis on EIGRP. The proposed work for these projects
is to an IP based network infrastructure has been developed for a renowned private
organization in Bangladesh. This network designs in scalable, secured, effective and
fault tolerable. LAN and WAN technologies are used and its collision free, full
duplex Gigabit &Fast Ethernet switching LANs design is proposed for 1000Mbps
&100Mbps data transmission. Point-to-Point (PPP) authentic link protocol is used for
serial connection between routers. Some departments are considered as separate
subnets and they are designed by VLAN concepts and this reduces the broadcast
traffic using classless (VLSM) IP addressing concept. A single Internet connection
(20Mbps) is shown with real IP (200.20.20.62/24) interface at the proposed design.
This network infrastructure design is simulated and tested with Packet Tracer 6.0.1.
Finally the evaluation results show that efficient routing approach of a network
infrastructure for a private organization is providing better performance.
