WAN Troubleshooting : Common Issues and Effective Solutions
We are living in a business world where interconnections have become a norm. Hence, to excel in your field, it has become imperative to have a trustworthy WAN.
Today, businesses have started to depend upon networks to function. This has resulted in growth in the management of these systems.
With the help of these solutions and platforms, you can get important tools. These tools assist you in getting security and making the most out of WAN.
Starting with the Basics
In simple words, a WAN is a complex network setup. It uses distinct LANs from different locations.
This way, it goes well beyond the traditional LAN capabilities. Think that you own a company that has branches in New York, London, and Singapore.
Your employees need to access shared files, communications, and databases. This is where the role of WAN starts.
WAN helps to connect these people located in different geographies. It does that through a single unified network.
In the modern era, the role of WAN has changed. Today, we see it in office spaces, which is pretty common. But now, businesses have started using it on cloud servers.
Apart from this, you can find them in remote workstations and even mobile devices.
With the help of WAN, businesses can function in real time. You do not have to worry about the physical location of your staff.
You can use WAN to perform video conferencing calls across countries. You can use it for video conferencing calls across countries. Or even better, WAN can help you get access to centralized databases for daily functions.
WAN is the silent hero that makes sure your business remains functioning. It does that with the help of the interconnection across the globe.
Common SD-WAN Issues
Here are some of the common SD-WAN issues that businesses face while using it.
1. Inconsistent Performance
SD-WAN provides much-needed improved nimbleness, concentrated control, and affordability. But, it is not short of challenges.
One of the most evident ones that businesses encounter is inconsistent performance.
This includes unstable network links, cloud service outages, and even inefficient routing. These can result in capricious network behavior.
To counter this challenge, businesses must use a multi-prolonged method.
Businesses can take the help of advanced monitoring tools. These tools can help businesses to provide real-time insights into network performance.
This assists administrators in learning and addressing blocks immediately.
Besides this, effective traffic precedence also proves to be a real matchwinner. It allows businesses to make sure critical apps get the bandwidth they merit. This guarantees smooth functioning.
Another crucial aspect is proper bandwidth allotment. It should be on the basis of specific requirements of distinct departments or apps.
Remember, it is not enough to have adequate bandwidth; you also need to know how to use it in an effective manner.
2. Security Threats
Today, businesses have no other option but to use SD-WAN solutions. But, at the back of their minds, they are always concerned about security.
Thanks to the decentralized nature of SD-WAN, businesses do get flexibility. But, it leaves various entry points. This makes your business vulnerable to potential online threats.
Businesses must integrate strong security measures to overcome these vulnerabilities. For that, they need to use digital certificates like Cheap RapidSSL Certificates.
This way, the data you exchange through the network remains encrypted. This helps in keeping it safe from cybercriminals.
Businesses must opt for certain platforms that can help them achieve the ultimate objective. These platforms can provide them with different security solutions.
The good news is, it is possible to customize these security solutions to suit different business requirements.
Furthermore, today’s businesses must invest in modern-day technologies. These include intrusion detection systems, firewalls, and frequent security evaluations.
Keep this in mind: in the world of SD-WAN, security is not an add-on feature; it is mandatory.
WAN Connection Error
Let us now look at the WAN connection error.
i. Physical Issues
The physical elements of a WAN setup, including cables and routers, provide the base. But, these elements can also wear and tear.
Some examples of this include misconfigured routers, loose connections, or even battered cables. These can prove to be a big disaster in the making for businesses.
It can result in periodic outages or weakened performance. To address this issue, businesses must take proactive measures.
This is where it becomes essential to conduct regular equipment scrutinization. This will make sure that every component is in the best condition.
Do not wait for the maintenance to become reactive. Waiting for that to happen can result in prolonged downtimes.
Besides, businesses might take the shortcut by selecting bargain-priced hardware.
But, investing in quality equipment is a wise investment for an extended period. It provides better performance and length of service.
Contemporary WAN Challenges and Solutions
Here are some modern-day WAN challenges and their solutions.
i. Inadequate Bandwidth
Today, businesses have started depending upon data-intensive applications. This is where if they get inadequate bandwidth, it can withstand their operations.
Hence, for the businesses, it is crucial to scrutinize the bandwidth usage. They should also check peak usage times and assign resources in an effective manner.
Businesses must ensure effective use of available bandwidth. This is during infrastructure upgrades or while adopting WAN optimization tools.
ii. Reliability Issues
Businesses run on money. Yet, when there is network downtime, it translates into lost revenue and productivity. To overcome this challenge, businesses should consider redundant links.
This way, if one link does not work, businesses have a backup plan to take over the next one. This guarantees continuous operations.
Besides, load balancing helps businesses to divide network traffic across many platforms.
This prevents any solitary server from getting overpowered.
Advanced Troubleshooting Methods
Here is a list of some advanced troubleshooting methods.
1. End-to-End Visibility
Whenever businesses go for WAN troubleshooting, visibility is an important factor.
Hence, it is imperative to opt for all-inclusive network monitoring tools. The reason is that they can provide insights from every endpoint.
This allows administrators to spot issues in a quick and precise manner.
2. Predictive Analytics
If your business wishes to troubleshoot WAN, it is crucial to be proactive. Predictive analytics tools can help you scrutinize network patterns and forecast potential issues.
With its help, IT teams can prepare for them even before they become big problems.
3. Network Bifurcation
Think of bifurcating a network as if you are compartmentalizing a ship. In case a component gets overflooded, it does not push the entire ship into the sinkhole.
In the same way, once you divide a network into segments, it is possible to restrain issues in a single segment. This assists in averting widespread collapses.
Concluding Thoughts
You must uphold the significance of a thriving WAN connection. Track the connection on a proactive basis. Finally, remember, in the world of WAN, it is always better to be risk-free.
