How to draw up a Logical Network Design?

Posted by & filed under Network Support. Protected by Copyscape

A logical network design is hard to implement, but one that is necessary for every business, since it is used to separate an entity from large networks or multiple networks. It is generally defined by its IP addressing scheme, which we’re using for the network. In order for us to understand the components of every logical network, there are four core aspects we should know about:

  • Broadcast address
  • The Network ID
  • The Subnet mask
  • Usable IP addresses

All 4 of these are present in all logical networks, and have to be accounted for when it comes to designing a logical network design. This is why it is important to choose the appropriate IP numbering scheme, and the subnet mask. They determine the number of usable IP addresses that can be generated.

If the network is within your company, you should ensure that it doesn’t overlap over other networks, since every network has to be unique, or else it will cause problems during routing.

 

Planning a Logical Network Design

When planning a logical network design, you should ensure that you start from a decent position. This will allow you to design and install a new network, or help you upgrade an existing network. It will ensure that all the information gathered is in one location, and will help you provide dependable services to clients, where you’ll be able to analyze traffic patterns as well.

It is important to find bottlenecks, and help create multiple paths by putting up servers that replicate important data, which allows load balancing. You also need to look at the following factors:

  • The clients

It is imperative that you account for the needs of the clients, and use data to handle all complaints.

  • Services

You should also know what kind of services you will be offering on the network, and whether you will be able to manage all of them. You need to account for a firewall between LANs so that you don’t suffer from any viruses.

  • Internet connection

Are you going to be offering an internet connection to customers, or will you just be allowing outside vendors to use your network? You need to know for sure what type of internet connection you will be using on your network.

  • Downtime

Make sure that you know what kind of network problems will cause downtimes, and whether your clients will be able to tolerate them.

  • Existing network

Make sure that your current network is up to date and will not affect the decision of coming up with a new logical network design.

 

Who Are Your Clients?

This is a simple question, but the answer isn’t so simple. You need to know more than just your client’s names; you should be able to assess patterns for different departments, so that you know firsthand about the needs of your clients. You should also know about the likes and dislikes of your clients, so that you are able to offer them with better services. In order to do so, you will be required to come up with a way to track that information and use it to improve your network solutions.

 

What kinds of services or applications will the network offer?

A lot of people know about the functions of their network, but not many are able to find out much about multiuser networks. You need to make a list of all the applications that will be used on your network, which will allow you to find out what kind of services or applications the network will offer. Every application on your network should come with a risk assessment document, which points out the potential security problem it could face.

This will allow you to properly secure your network, and get versions of applications that support your network. When choosing applications for your network, make sure that you know about these following things, and implement them:

  • Is the application safe?

A lot of applications today have different secure versions, which can be used with a proxy. They have been used by some of the biggest organizations, and ensured that their staff was able to prevent network downtimes. This was helped by proxy servers, which are important parts of firewalls.

  • Does one application overlap another?

Every user has got their own personal favorite application, and you may notice that some people like a particular word processor, while the others like another one. When it comes to dealing with application suites, or applications, it is imperative that you make a good choice and stick with it. Especially, if it is working well with your network, in which case, you have to make sure that you train your staff in a manner that goes along with the applications you are running on your network.

 

Getting information

One of the most overlooked means for gathering data files on a network, and sending them onto the internet is by simply sending them as attachments with an email. This can be done with new applications as well, since the email will go through the firewall and carry important information with the attachment. You need to find out whether you have existing applications that can do this job, otherwise you will have to install a new application, or service that will help you access the network.

It is important that you know about applications that are used to gather information, since it will help you figure out whether you need new applications yourself. Also test the applications you are getting so that you know exactly what you should be expecting from it. The last thing that you need to do is constantly monitor the usage of the network.

This will help you properly identify, which users are accessing your network and how they are spending their days, whether by browsing the net, or checking their personal emails at work. Most companies have policies, which apply to using the phone for personal business.
