What exactly is network architecture? Network architecture is the art of designing a complex network, often based on the butterfly effect. Network architecture is often compared to the internet or large computer networks. Network architecture is an important topic in Computer Network Architecture. Network architecture is basically the method of planning a complex network using computer science tools such as routing tables, routing protocols, and IP networking.
Networking describes how computers will connect to each other and how they will work together. The Internet is considered to be one of the largest and most complex systems of network architecture. Networking in computer systems allows computers to communicate with one another and to send and receive data communication over various networks (either physical or logical). Networking has many different protocols that allow different computers to communicate with each other and with remote devices. There are three different protocols that are used in common computer systems: BIC, WAN, and VPN.
BIC stands for backbone in computer network architecture. A backbone is a central computer that provides a platform for multiple networks to connect to it. In the case of BIC, it provides the foundation and a common set of connections for several local area networks or LANs. This can help reduce the cost of deployment for smaller local computer systems. However, BIC does not provide security in the form of authentication.
WAN stands for wide area network
Wide area networks are simply large networks that span the entire continent or even the world. They connect millions of computers and are used for various business operations. The role of a network architect in WAN is similar to that of the BIC. However, WAN requires more security since anyone with malicious intent can easily breach the entire network if given the right opportunity.
VPN is a type of virtual private network that allows two or more computers to become one computer in the eyes of other network users. This allows the users to bypass firewall protection and allows data to be protected even from outside threats. This is how VPN is often used by corporations and professionals as it allows data to be moved from one location to another without being compromised.
Aside from the three main types, there exist many subtypes of these architectures. The most basic ones are the private and public networks. A private network has only one server go to connect to other computers, while a public network allows multiple computers to connect to each other for data security purposes. Most businesses use the latter especially in large organizations where multiple companies share the same network.
The third type of architecture, which is also called backbone architecture, consists of a central server that serves as a hub of connections between various computers. For example, you have a peer-to-peer network consisting of ten computers. All the computers in the network are connected to the server. The server serves as a hub through which all the computers connected to it communicate with each other through their local area network (LAN). This is the most common scenario of a backbone architecture.
Although there are a number of networks available out there, the most popular ones are Ethernet, wireless and VPN. All three types have their own advantages and disadvantages. The most recent technology in the list is VPN or digital network architecture. With the help of this technology, computers can securely connect to each other regardless of whether they are within the same metropolitan area or thousands of miles away.
To elaborate more on what is peer-to-peer architecture, let us take a look at its basic mechanism. Here, a user connects to the network via a modem, downloads data from a web service provider, sends the requested data to the receiver, and finally receives it. Once the entire process is completed, the user can simply disconnect from the network. Such features make this kind of architecture very secure since anyone can trace your every move by simply observing your computer’s IP address. And because you can easily disconnect, you will not be bothered by those mysterious people who were just observing your every move.
Another thing that should be considered with network architecture is the security of the networks. As mentioned earlier, one of the biggest threats to these networks is the Mirasursion attack, which is a remote attack wherein an attacker gain access to one computers internal memory using a keylogger. With an entire network’s memory being hacked, it will surely bring catastrophic results to the whole system. Therefore, companies and computers should always employ the use of firewalls and other protective measures to ensure the security of their networks.
Apart from these, the other important things to consider in answering the question what is network architecture is the different types of protocols that are used to establish the different connections. This includes ICMP Echo Request, ICMP Echo Relay, TCP Relay, MPLS VPN and IPsec. All of these are protocols that are used to establish a secure tunnel for transferring data and information. Each of these protocols has its own security mechanism that must be employed by every computer to prevent Mirasursions and other attacks.
