Let us assume that we have a project design can be integrated on the computer network of the organization that many sites do that to a single plan virtual private network, what you take contains? Be developed as a team leader, a time frame of the project after the general has only the brainstorm to include to collect as much as possible, the draft plan, budget estimates, in conjunction with the third and so on.
It's quite difficult to start a project properly without knowing exactly what the strengths and weaknesses of supporting infrastructure which the system will base on.
E then should a computer-network project with a brainstorming session to begin to collect data as possible.
Assume this computer network design will involve three sites: one main headquarter office in Sydney, one main office in Jakarta, and one remote site - the gold mine in the middle of the Borneo jungle.
The head of the organization wants to allow all sides to a single computer network to facilitate communication between company locations, including data, voice or video conference, probably from the course and allow easy communication with the world.
Telecommunication Requirements
The first data for your computer network design that needs to be collected is the telecommunication system requirements.
The most important question is how to connect all locations to happen to the communication system.
The following questions can be used to collect the data for the telecommunication requirements.
1.
How to arrange the Telecommunication service in remote site? We understand that both the main offices in Sydney and Jakarta are located in the area where you can find lots of communication services.
And the remote site - the site in the jungle? It will provide recommended in conjunction with third-party IT services company WAN - probably uses satellite communication link.
2.
Gather the information form of communication for the remote site to the directory Jakarta office will be allowed: only data, voice, video, or a combination of these.
This information is important to help you determine how wide the satellite link bandwidth you need.
In this way is expensive to relate the budget via satellite.
3.
What kind of WAN technology to link data between Jakarta and Sydney, Frame Relay, ISDN network, VPN connection? Connection with the third part - the telecommunications company to help.
You need to dig and find more data that specific to the project.
Telecommunications requirements should be resolved before you can proceed to collect the requirements of other infrastructure in this case.
Network Infrastructure Requirements
Second requirement for your computer network design is to collect data regarding the network infrastructure requirements.
All data for logical and physical infrastructure must be picked up as much as possible.
The following questions can be used to collect the data.
1.
How many hosts will be in each site including workstations, servers, switches, routers, wireless access points, and VoIP.
This will help you calculate and make the IP address requirements.
2.
Collect information with the main direction when they need to host public funds in both Jakarta and Sydney sites.
If so, where will all the public resources be located, inside the private network or in the DMZ (perimeter network)? This will help in designing the entry-point security.
Hosting public funds must be made safe domain names, domain names, such as between internal use and public.
3.
Gather information on safety requirements for the internal network.
Will particular sections or departments need security boundary? This will help in designing your computer network if the network segmentation within the local network is needed.
It also helps in shaping how users are grouped and develops appropriate strategies to meet the safety requirements.
4.
Collect information with the main direction of development of service level agreements on the availability of network resources.
How critical the network resources will affect the business continuity if they ever fail to function.
This will help, resource requirements, such as the need for redundant cluster plan, load balancing, etc..
5.
She is collecting information about the location of each site as the power as well, as long as the distances between each building, which is connected to the network, you can use the network cable or wirelessly.
If the wireless connection is needed, examine how the attenuation factors will affect the wireless performance.
6.
Collect the information if the travelling users or tele-workers will be allowed to access the corporate network resources.
This will help you, your VPN requirements and safety requirements regarding the authentication and authorization for the remote connection.
7.
And even more important excavations demands on the infrastructure that is specifically for the project in context.
By having the brainstorming data regarding the infrastructure requirements you can make the budget regarding the hardware, software, and consultants requirements for the implementation of your computer network design.
Disaster Management When designing computer networks, disaster recovery and business continuity planning must be present.
The what if this fail question should base all the decisions of your design including selecting the location, hardware, software, models, the third party involves and so on.
For example in the construction of the server room, is a wise decision to not fill up on all the servers in a single room of the main server.
Another alternate server in different building would be much better to avoid a single point of failure in case of the main server room is totally burned in fire disaster.
Be the schematic structure of computer network design must be scrutinized.
Risk security assessment must be performed to help you design the appropriate control to reduce the possible threats to occur and if the threats ever occur, what actions must be taken to allow the business to run at least in the minimum operational level.
In the design of computer network should also ease in the maintenance of the system followed by the administrators and provides a complete documentation including user manuals and disaster recovery planning.
