Network Architecture: Types, Design, and Importance
Network architecture connects computers to the internet. It’s crucial to design networks that can handle high-bandwidth and high-performance computing, as well as security. Network architecture determines the flow of data within an organization. Pitfalls in network design can cause inaccurate data, delays, or unhappy clients. Choosing the right solution is essential.
Understanding Network Architecture
Network architecture refers to the design and implementation of the flow of data between systems, which is facilitated by an application services layer or middleware. A logical network consists of policies that govern device connectivity based on location and capabilities. Performance standards are used to forecast network growth and plan future upgrades. Role-based access control ensures security by authorizing groups or roles. Virtualization enables the delivery of networking services over the internet, and software-defined networks are becoming the norm. While remote working has benefits such as access to data and better collaboration, virtual offices are not a substitute for a safe and healthy work environment.
Types of Networking Architectures
Networking can be either private or internet-based. It is crucial to differentiate between the two.
Private Networks
As cloud technologies and the Internet of Things continue to expand, there is a growing need for accessibility between data storage and exchange sites and devices. To address this need, telcos must select the appropriate WAN solutions to streamline WAN links between their data centers and clients. The monitoring and maintenance of private networks differ from public networks, requiring more detailed and comprehensive attention to ensure protection against potential threats.
PUBLIC NETWORKS
Cloud services provide enhanced performance and capabilities compared to traditional software and require simpler maintenance of computing and networking systems. It is essential to consider the cost and benefits of cloud services based on the location of the service provider. For instance, hosting providers may offer cloud services in one country while having data centers in another. Thus, it is crucial to comprehend the regulatory and cultural environment of the cloud service provider’s operation while assessing the location of cloud services.
Building Trust: Enhancing Security with VPNs and Zero Trust Networks
Virtual private networks (VPNs) provide security and privacy while granting access to global content and data. However, they can also become a cybersecurity vulnerability. To minimize this risk, security controls should be implemented. VPNs can enhance the security of devices and data endpoints in the corporate network.
Zero trust networks (ZT) have shifted from protecting trust networks to protecting every individual resource. This means that authentication and authorization should be required for every device, method of connection, and resource access.
Optimizing Network Architecture Design
To ensure the success of any digital network architecture, it’s crucial to optimize the building blocks. These building blocks include the network layout, hardware components, and software systems. By carefully designing and implementing each of these elements, you can create a network architecture that performs at its best.
HARDWARE
To optimize your network, you can segment it, merge segments, or use a hybrid approach. Also, consider the hardware’s impact on your data, including mobile phone bandwidth and download volume per day. Additionally, decide whether to use a wireless or wired network. When evaluating hardware, it’s important not to focus solely on size. Remember, as the network grows, a single point of failure can cause all links to fail.
Transmission Media
Transmission speeds range from 1 to 100 Mbps based on network technology and implementation conditions. A typical home internet connection delivers 1-10 Mbps, but Internet Service Providers often offer faster speeds to increase profits. In online gaming, high-speed internet is crucial for games played at high resolutions and frame rates, such as first-person shooters, to maintain player interest. Poor internet connections can drastically reduce gaming performance, much like poor cell service can cause GPS navigation delays.
Network Protocols
While iOS developers are mainly familiar with HTTP and HTTPS, these are not the only protocols available. Protocols govern data transfer between devices in a network and enable communication between them. Without these, your iPhone cannot connect to a Linux server. Networks use TCP/IP, Ethernet, FTP for internet connection, and other protocols for specific contexts.
Network Topology Overview
Network topology is an essential aspect to consider when building a network. Understanding the wired connections is crucial to improve it effectively. Each topology has its benefits and drawbacks. A star topology is simple to connect devices but does not provide any real advantage over other topologies. Meanwhile, a bus topology, such as a ring network, is a cost-effective way to connect a large number of devices and can be repurposed for different needs. Other common topologies include fiber optic, copper, wireless, and mesh.Advantages of Network Architecture
Benefits of Computer Architecture:
– File servers are highly secure and efficient for private networks, allowing organizations to share files and resources without networked computers.
– Modern technology enables children interested in science or tech to join a network for socializing.
– Disintegration of extensive procedures into smaller steps minimizes problem-solving time by involving all components.
– Redundancy helps maintain smooth operation during equipment failures or poor network connections.
– Understanding the whole product requires knowledge of the language, the software development team, process, and tools used to build it.
– Encryption of sensitive information prevents unauthorized access to it.
– Awareness of how assets are shared among individuals and legal implications of owning them can be maintained through legal inventory, identifiers, and agreements.
Disadvantages of Network Architecture
The main drawbacks of computer architecture include:
– Reliance on a primary server to store, receive, and distribute data, which may not be the same computer that stores the data.
– Challenges with selecting the right operating system for company-wide use.
– The need to keep a close eye on all devices and utilize a trusted computing platform with regular maintenance.
– High costs associated with cabling and equipment for building a system.
In general, these challenges can be accounted for with thorough planning and research before setting up a network architecture.
Network Architecture
A network architecture’s main purpose is to provide a structure for managing and organizing the network infrastructure efficiently. The architecture should ensure the optimal use of network resources. Therefore, the architecture’s structure is the most critical aspect that should be organized systematically.
