1. Introduction
The company has six offices, network administrator of the company want to fix the LAN and
WAN network. The employees in all six offices are needed to communicate both internally in that office.
70 kilometers is the main distance between any two offices. Mostly the user resource requirements are
met by the server in the same office. The offices establish their communication by using emails and file
transfer.
For example, consider the multi floors building. The head office occupies first three floors of the
building, the head office consist of three different departments. They are general support department,
marketing, and sales department. The first occupies by general support, the second floor occupies by
marketing department, and third floor is sales department. Each department has no of workstation, 32
workstations in general support, 20 work stations in marketing, and 38 workstations in sales
department. Now we want to create the network for everyone easily manage the communication. And
the potential impact of the problem is reduced. The network implementation is done by wired network.
2. WAN technology
The WAN technology is used to implement the MPLS WAN. And also is considering traffic
requirements and cost implication. The efficient traffic transfer is done by MPLS, and it provide lot of
advantages,
 Two types of MPLS is used one is static and another one is dynamic for increasing the
availability
 It support several remote sites
 The single edge routers are utilized
 And also it is a cost effective model
 The network traffic support high data rates
The connection is made by demand basic, connect the high latency but it depends upon the
connection speed. The minimum reliability is used. The dial up setup is used for limited the connection
speed. The data flows of the network are improved by standard MPLS technology. The infrastructure
management is used to reduce the time limit. The internal protocol is operated by dubbed multi
protocol technology. Different types of protocols are used in WAN network
