Delving into Networks: Key Considerations for Understanding Your Environment

A data network is a system of connected devices that allow for the transfer and sharing of information. It is the backbone of modern communication and essential for many aspects of our daily lives, from staying connected with friends and family to conducting business and managing finances.

Think of a data network as a highway for information. As a highway connects cities and towns, a data network connects computers, smartphones, and other devices to communicate and exchange information. This information can be anything from text messages and emails to photos, videos, and even critical financial transactions.

It is important to note that data networks are not limited to a single device or location. They can range from small local networks within a single building to large, global networks that span the entire world. Regardless of their size, data networks play a critical role in our lives and the functioning of modern society.

Navigating Connectivity: Exploring the Intricacies of Network Environments

Data networks have a profound impact on organizations and individuals who use applications. They enable organizations to streamline their operations, improve communication and collaboration, and access real-time information. For example, businesses can use data networks to manage their finances, customer relationships, and supply chains, making them more efficient and competitive in the marketplace.

Data networks provide individuals with instant access to information, entertainment, and communication. People can use applications to access the latest news, connect with friends and family, and even shop and manage their finances online. With the growing number of connected devices, data networks have made it possible for people to stay connected and productive, no matter where they are.

Moreover, data networks also impact the security and privacy of organizations and individuals. As more sensitive information is transmitted over networks, it is important to ensure that this information is protected from unauthorized access and cyber-attacks. Organizations must take steps to secure their networks and protect their customer’s information, while individuals must be mindful of the information they share online and the security of their devices.

In conclusion, data networks have revolutionized how organizations and individuals communicate, access information, and conduct business. They have enabled organizations to be more productive and competitive while providing individuals instant access to a world of information and entertainment. However, with the benefits of data networks also come security and privacy concerns that must be addressed to ensure the continued safe and secure use of these networks.

Each section below describes the Features and Benefits to help you choose the best-optimised solution for your infrastructure.

Challenges and Opportunities

Any Medium/Enterprise Business, University, or Healthcare Clinic/Hospital face enormous challenges in developing and maintaining infrastructures that keep pace with high technical demands. Technology must support and enhance research efforts, offering new methods to increase productivity and efficiency.
Combined advances in switching technology and WLANs help financially constrained businesses achieve more value and functionality within their existing budgets. For a very reasonable cost, universities, companies and hospitals can implement an infrastructure supporting a wide range of leading applications. These technologies enhance how information is communicated and accessed, providing a more optimal infrastructure that delivers efficient tools and resources.
Professionals at v500 Systems have delivered several projects addressing the challenges mentioned above.

Local Area Network (LAN) and Wide Area Network (WAN) – Wired Technologies

High-speed LAN technologies using Copper or Fiber connections at 1/10Gb speed can significantly enhance the overall network environment. At the WAN layer, cost-effective broadband capabilities will provide much-needed bandwidth to the Internet.

Wireless Local Area Network (WLAN) – Wireless Technologies

WLAN technology affordably extends your network’s flexibility when it is not practical to install cable or when flexible, mobile access solutions are required. Wired and wireless technologies each have a place in the campus LAN and collectively deliver LAN-to-LAN capabilities.
Users use “Bring Your Own Devices” (BYOD) to work more often. Mobile phones and tablets are used very frequently in any business environment. Wireless speeds match those at the wired network, and there is considerable cost savings on cabling infrastructure. We think that Businesses should take advantage of those benefits.

Deploying Branch and Campus LAN

Network infrastructure is optimised with a configuration that delivers sufficient bandwidth and intelligence to meet increasing traffic demands, with additions of robust quality of Service (QoS), High Availability, ease of Management, and Strict Security with Access Authentication Capabilities.
The above features allow the Network Infrastructure to support a broad spectrum of services, and importantly, it is scalable, so it will grow with the Business.
v500 Systems have deployed many network environments; please see our Case Studies
With technology development, there is a more cost-effective way of deploying very scalable and secure SD-WAN solutions.

Process of Building Network Infrastructure

Next-generation applications demand support in colleges, universities, clinics, and businesses and fully take advantage they will need to upgrade their LANs. They must migrate from shared hub technology to a switched infrastructure at the most basic level. Many campuses also will want to use faster, more intelligent technologies, such as Gigabit or 10 Gigabit Ethernet. Besides, businesses may wish to integrate wireless technology into their environments for greater user mobility and LAN accessibility.

Migrating from Hubs to Switches

A small home setup is the only environment where you can get away with hubs. In the current day and age, at least 10/100/1000 Mbps switches are required. Switching is much more intelligent as it forwards traffic only to desired ports instead of flooding traffic out of all ports. Better still, a multilayer switch is a better option if you require routing in the future. Professionals at v500 Systems can advise you on what is best suited for your environment.

Migrating to Multilayer Advanced Switches

Every company needs to be on advanced multilayer switches because applications and users are very demanding, which is a benchmark of successful networking. We at v500 Systems can help you to achieve this level if you are not already there.
Brief Summary: For many campus environments with hubs or Ethernet/Fast Ethernet switches, a migration to advanced, higher-performance, multilayer switches will also be necessary. The reason is simple: With the growth of multi-point traffic and the introduction of demanding bandwidth-hungry applications, the network is under increasing stress. Inevitably, we need to increase bandwidth at the backbone of the system or the top of the stack.

Wired and Wireless together at last

For many campus environments, wireless technology is an essential addition to the network. In a high-performance switching context, wireless technology can deliver Ethernet-level speeds reaching 11 Mbps or higher to open areas. Wireless can dramatically improve the usability and scalability of the existing network. Many successful campus implementations have shown that wireless technology delivers substantial administrative, learning, and cost-saving benefits.
Our Network Engineers at v500 Systems can assist your Business in configuring agile Wireless Infrastructure.

Combined Wired and Wireless, End-to-End LAN Solution

The culture and lifestyle of offices/businesses are changing. Users tend to have meetings in common areas and cafes. Also, wireless networking dominates this field in warehouses as it makes communication much more manageable. However, for wireless networking, a fibre backbone is the key to high-speed networks and resiliency of access points. It integrates key network management to simplify operations, administration, and security features that protect data and user privacy.

Network Switch Solutions, End-to-End

v500 Systems makes it easy. We offer end-to-end solutions for every point on the network: from the Access Layer, through the Distribution Layer to the backbone to the Network Core. We extend the system and accessibility using Wi-Fi. Everything that a medium/large business needs to deliver network infrastructure affordably and securely.

Enterprise Infrastructure – Professional Solution for Campus, Branch and Data Center Network Infrastructure

At this level of networking, we heavily rely on Cisco Nexus devices. The reason behind it is quite simple, modern Data Center’s workload must excel in server-to-server traffic with intensive communication across thousands of servers. Therefore, your Business needs automation across the entire Data Center platform, operations and business processes to enable users, companies and partners to respond faster to the application changes required in real-time.
By automating the network from Edge to Core, enterprise to Data Center, and embedding infrastructure learning, analytics, and assurance at the foundation level. You can focus on running your Business, not on running your network.

Data Center Networks consist of 5 Tier Layer.

• Network Exchange Layer – this is where other Data Center, Major remote Branches, or 3rd Party Clients connect.
• Core Layer – highly resilient connectivity within Data Center, Uplinks to Network Exchange and connectivity to other Data Centers within the same country
• Distribution Layer – at this layered network is segregated into Blocks, VRFs, and Firewalls that provide traffic filtering and Load-Balancers, further resiliency for the applications.
• Spine Layer – Backbone for the FabricPath and Leaf environment
• Leaf Layer with Fabric Extenders (FEXs) – VMWare Chassis usually connects to the Leaf Switches and other Servers to the FEXs (Top of the Rack switches)

Next-Generation Data Centers

Core needs to drive data Centers:

• Need for a higher level of reliability, with minimised downtime for updates and configuration changes
• Need to optimise the use of the data centre network infrastructure by moving towards a topology where no link is kept idle
• Need to maximise computing resources by reducing the growth rate of physical computing nodes. This need is addressed by server virtualisation.
• Need to reduce the time that it takes to provision new servers
• Need to reduce overall power consumption in the Data Center
• Need to increase computing power at a lower cost

The above “wish list” can satisfy the following Features and Benefits.

• Architectures can support a SAN and a LAN on the same Network Infrastructure.
• Architectures that provide intrinsically lower latency than traditional LAN networks.
• Architectures that provide the ability to distribute Layer 2 traffic on all available links.
• Simplified cabling: For a more efficient airflow, lower power consumption, and lower deployment cost of high-bandwidth networks.
• Reduction of management points.

Vital elements in Next-Generation Data Centers

Data Center Pods

Each access layer in the data centre is “divided” in pods (building blocks), where servers in each pod share similar characteristics, whether these characteristics are identical hardware, related SLAs provided to the customer (internal or external), and so on. This scenario is different from building separate silos for each business unit. In a pod design, multiple business units may share the same pod and run on similar server platforms because of the similar level of service required.

All Links Forwarding

The next-generation data centre allows all links in the LAN topology to be used by taking advantage of technologies such as virtual PortChannels (vPCs). vPCs enable full, cross-sectional bandwidth utilisation among LAN switches.

10 Gigabit Ethernet to the Server

Servers connected at 10 Gigabit Ethernet benefit from a reduction in the number of Gigabit Ethernet adapters needed. They also increase network bandwidth and allow for the consolidation of storage traffic with LAN traffic.

FabricPath on Nexus – a flexible solution

The most significant advantage of FabricPath is that it gives us flexibility along with loop-free connectivity that STP couldn’t do and is, therefore, run in Data Centers as a replacement for Spanning Tree Protocol. Cisco FabricPath: Cisco FabricPath is about routing your data centre traffic and helps to do load-sharing

Fabric Extender

Fabric extender technology simplifies the management of the many LAN switches in the data centre by aggregating them into groups of 10 to 12 under the same management entity. In its current implementation, Cisco Nexus 2000 Series Fabric Extenders can provide connectivity across 10 to 12 racks managed from a single switching configuration point, thus bringing together the benefits of top-of-the-rack and end-of-the-row topologies.

Using Cisco Nexus Switches and vPC to Design Data Centers

Virtual PortChannel (vPC) allows links physically connected to two different Cisco switches to appear to a third downstream device as coming from a single device and as part of a single port channel. The main benefit of running vPC on the data centre is that the traffic between client and servers or from server to server can use all the available links and is loop-free.
In a vPC topology, all links between the aggregation and the access layer would be forwarding and part of a virtual PortChannel.
