Suppose you are called to lead a project, an organization of computer network that many sites that need to be integrated into a single private network includes the design, what will you do? As team leader, proposed a period of time, the general must be developed, which are the exchange of ideas, as much as possible data are collected, belonging to the draft plan, budget estimates, in close collaboration with the third and so on.
It ‘very difficult to start a project successfully, without knowing exactly what the strengths and weaknesses of the supporting infrastructure that is based on the system. Therefore, a computer-network design begins with a race to collect as much data as possible.
Suppose that the computer-network design are developed in three locations: an office in Sydney, an office in Jakarta, and a remote site based – the gold mine in the middle of the jungle of Borneo. The director of the organization to thank all linked pages on a single computer network to facilitate communication between corporate sites, such as to enable data, voice or video, and, of course, probably to allow easy communication with the world .
Requirements for Telecommunications
The initial data for the design of computer network needs to be taken with the needs of the PBX. The more important question is how to connect all system pages so that communication happen. The following questions may be used to collect data for the needs of telecommunications.
1 How do you organize your telecommunications services in remote locations? We know that both in Sydney and Jakarta based in the area where you can find many communication services. And the remote site – the location in the middle of the jungle? Please contact the third party companies to provide WAN technology – perhaps with satellite communications to connect.
2 Collect information, what kind of communication to the remote site, the Jakarta office will be allowed: data, voice, video, or a combination thereof. This information is important to determine the width of satellite broadband, you need. This is the budget in context because it is expensive satellite links.
3 What kind of WAN technology connecting data between Jakarta and Sydney, Frame Relay, ISDN, VPN connection? Contact with the third – to help the telecommunications company.
You have to dig and find out the details of the project. Telecommunications must be resolved before you can proceed to collect the requirements of other infrastructure, in this case.
Demands on network infrastructure
Second condition for the design of its computer network is to collect data on the requests on the network infrastructure. All data for logical and physical infrastructure needs to be withdrawn as much as possible. The following questions may be used to collect data.
1 How many hosts will be on each workstation, servers, switches, routers, wireless access points and VoIP. This will help in the computational requirements and the design of IP addresses.
2 Gather information from the management of major cases, they need to organize public funds, both in Sydney and Jakarta pages. If so, where public funds are within the private network or DMZ (perimeter network)? This will help in the planning of safety point. Taking public funds, the domain name be such that the domain names sure to distinguish between internal and public use.
3 Gather information on safety requirements for the internal network. Special sections or departments will be safer to look at the limit? This will help in the design of computer network, if the segmentation of the network within the local network is required. It also helps to shape how users are grouped and the development of appropriate strategies to meet safety requirements.
4 Gather information from key management, develop service level agreements on the availability of network resources. How important network of resources affects the continuity of the business, always when you stop working. This will help you understand the needs of redundant resources, the need for clustering, load balancing and so on.
5 She is collecting information on the location of each site, as well as the power to be as long as the distances between each building connected to the network, you can use the network cable or wireless connection. If the wireless connection is to consider how to influence the damping wireless performance factors.
6 Collect the information if the users who are traveling or remote workers are allowed to access corporate network resources. This will help you, your needs and security requirements for VPN authentication and authorization for the remote connection.
7 digs and more importantly in terms of infrastructure requirements that are specifically for the project. After brainstorming on data requirements for infrastructure, the budget in terms of hardware, software and consultants who implement the project network.
Disaster Management
In designing the network, disaster recovery planning and business continuity must be in your head. The question of whether the basis for all decisions related to planning, including site selection is the hardware, software, models, and the third and so on. For example in the construction of the server room, is a wise decision not to fill up all the servers in a single primary server. Another alternative servers for the construction of several would be better to avoid a single point of failure, if the main server room is completely burned in the fire disaster. The schematic design of the computer network must be examined carefully. The security risk assessment should be undertaken to design the appropriate control of potential threats that may occur are reduced, and if the threat occurred, the necessary measures to make the company run at least as a minimum.
In the network design should include maintainability of the system administrators can then, complete documentation, including manuals and disaster recovery planning.
