The literature review is about the study of the network design of the Department of the Interior and Local Government, wherein there are different networks or technologies to be used and the security purposes of the office. This review also includes the possible devices to be used, according to our client it is convenient of any devices the important thing is that traffic within every department and also from the regional offices must be prevented. There must be a Quality of Service to take place so that connection will be maximized such as there are things like personal emails, data transfer, and company email servers can be delivered as efficient as possible and to prevent delay within every division. As DILG have a 7 year network design but it is not satisfying due to slow connection and old equipment. They have a good service such as primary health care; supervise the administration & governance of the local government, etc. therefore a much broader connection must be achieved to give back also to people the help they deserve. According to the – Phi Beta Lambda (FBLA-PBL) network design provides for centralized management and control of the computers in the two stores, so that you can maintain the network from off-site. Compare to their music stores, wherein their stores are in different places, our client also want to have a connection directly from the Central Offices to the Regional Offices through WAN.
Use the technology that ﬁts
“All of these network designs can be used to complement each other in a large network, and can obviously make use of traditional wired networking techniques whenever possible.” In our transcript of Interview our client said that they need LAN, WAN, & VPN in their office. Local Area Network (LAN) is used to connect devices within the area, but in our client’s case LAN will be used per department not per floor. It is said to prevent traffic that can cause delay inside the office. Wide Area Network (WAN) network that covers a broad area wherein the client is in capable of tracking or receiving and sending files to the regional offices data. They said that some of the people in their regional offices tend to send emails but some of it is delayed due to users and also people travel to central offices personally just to send data, such a waste of time. Virtual Private Network (VPN) extends a private network across public networks like the Internet. Just like WAN it is a network used to broad area the only difference is that VPN has security purpose. There are two types that VPN can be classified with the site-to-site and the remote-access connectivity. Site-to-site connectivity is to secure connection within the DILG offices wherein guest in the area is required to ask permission of the security. The DILG office is adequate to imbed the security purposes of the building. Remote-access connectivity is where employees will create or establish to secure the connection. In that case, the head of every department has the right to place security of the connection. The security connection is between every department only therefore there will be a specific or different security per department. Therefore DILG is using the site-to-site connectivity wherein DILG’s IT Department is the one who will be creating or implementing the security purposes of the whole DILG. As said, there are many types of network or technology that can be used in order for an office will be connected near or far to each other with security or not.
“Bandwidth is measured as the amount of bits transmitted over a time interval. This means that over time, bandwidth available on any link approaches inﬁnity.” “QoS refers to the capability of a network to provide better service.” DILG will signiﬁcantly improve response time and maximize available throughput by eliminating unwanted...
