TCP monitoring – Everything you need to know

  By , ,

Are you looking to improve your network performance and reliability? Then, TCP monitoring is the solution you need! It provides visibility into the connection process, helps diagnose and address problems quickly, and allows you to prioritize different applications and services. Read on to find out everything you need to know about it!

TCP Monitoring – What is it, and why is it important?

TCP monitoring is an advanced network monitoring solution that allows network administrators to monitor the Transmission Control Protocol (TCP) operation closely. The advantage of this technique is that it provides visibility into the steps that ensure connection reliability between two devices in different networks. This includes inspecting packet headers and sequencing acknowledgment messages, which can help identify problems such as traffic congestion or network segments with slow connection speeds. In addition, proactively monitoring and recording the status of all TCP connections within the network allows administrators to detect and address any issues quickly before they can cause further disruption or service degradation.

Benefits of TCP Monitoring

One of the critical benefits of Transmission Control Protocol monitoring is that it offers improved overall network performance. By monitoring the connection process and implementation of all the TCP connections in a network, administrators can gain valuable insights into network congestion, packet loss, and packet delay. This helps identify slow connections or networking problems and makes diagnosing and fixing them easier.

Transmission Control Protocol monitoring also provides valuable data on how different applications are utilizing the network. This helps administrators detect applications hogging too much bandwidth or eating away QoS resources, which can lead to performance issues. With Transmission Control Protocol monitoring, administrators can prioritize different applications and services, allowing business-critical applications to get the needed help.

Finally, it increases the available data for troubleshooting and hazard detection. By monitoring and recording Transmission Control Protocol connections over time, administrators can spot and proactively address upcoming problems before they take down any systems or applications. This helps maintain network reliability, reduce downtime, and ensure networks function optimally.

How to take advantage of it?

Implementing automation is one of the best ways to take advantage of TCP monitoring. Automated TCP monitoring solutions can provide real-time monitoring and alerting to identify any abnormal activity, such as high throughput or latency. Automated solutions can also provide detailed reports on network performance and application traffic, helping administrators spot any unusual patterns or suspicious connections. With automation, administrators can ensure an accurate and up-to-date view of their network performance, allowing them to identify and address any issues that arise quickly.

TCP Monitoring vs DNS Monitoring vs Ping Monitoring

TCP monitoring, DNS monitoring, and Ping monitoring are all types of network monitoring used for the same purpose: to measure and analyze the performance of a network. The key difference between each of these solutions is the protocol they are designed to monitor. For example, TCP monitoring monitors the Transmission Control Protocol, DNS monitoring monitors the Domain Name System, and ping monitoring monitors the Internet Control Message Protocol. Each solution has its own strengths and weaknesses, so network administrators should assess their specific needs to decide which solution is best for them.

Conclusion

TCP monitoring provides a powerful solution for improving the performance and reliability of a network. Monitoring Transmission Control Protocol connections and providing administrators with data on network congestion, packet loss, and packet delay ensures that any issues can be quickly identified and fixed to maintain optimal service levels. If you want to take advantage of the benefits of Transmission Control Protocol monitoring, implement automation for real-time monitoring, alerting, and detailed reporting.

What is TCP and Why Should You Care?

  By ,

When connecting two computers to exchange data, TCP (Transmission Control Protocol) is the go-to protocol for reliable and secure communication. In this blog post, we’ll be exploring exactly what TCP is, how it works, its advantages and disadvantages, and its role in DNS. Keep reading to find out more!

Explanation of TCP

TCP (Transmission Control Protocol) is an end-to-end transport layer protocol used to establish connections and exchange data reliably between two computers over a network. It is an integral part of the Internet Protocol Suite and provides a connection-oriented service between two hosts. Using the reliable and efficient TCP protocol, network applications can send data reliably over the network without complicated protocols such as FTP. With its reliable and efficient data transmission, Transmission Control Protocol is ideal for applications such as web browsing and data transfer services.

How does it function?

TCP uses a set of rules known as a transmission control protocol. This protocol establishes a reliable, connection-oriented link between two computers and transfers data in a series of bytes. This is achieved by breaking the data into small chunks and adding a sequence number to each data part. Then, the receiving computer reassembles the data in the same order it was sent. Additionally, Transmission Control Protocol also has features such as error checking, retransmission of lost packets, and flow control to ensure the reliability of the data transfer. By following this protocol, TCP can reliably send and receive data between two points, creating a foundation for all the information we communicate on the internet today.

Advantages and disadvantages of TCP

One of the main advantages of the TCP protocol is its reliability. Following the designated rules and sequence of the transmission control protocol, TCP ensures that data is reliably sent and received in the same order. As a result, network applications can be confident that the data they are sending or receiving is accurate and complete. Additionally, TCP’s built-in error correction and flow-control features guarantee that connection-oriented issues, such as resending lost packets and controlling the data flow, are taken care of automatically.

Despite its advantages, TCP also comes with some disadvantages. One of the most significant drawbacks of the protocol is that it can be slow, especially compared to other connectionless protocols such as UDP. Additionally, Transmission Control Protocol requires an extensive amount of additional overhead information, resulting in more network traffic. This can lead to slower speeds and higher latency on networks with limited bandwidth. Finally, TCP is connection-oriented, meaning it cannot function properly on connectionless networks such as mobile networks. For these reasons, other protocols, such as UDP, are sometimes used instead.

The role of TCP in DNS

TCP plays an essential role in DNS (Domain Name System). It is explicitly used for resolving domain names, which means it sends the queries to the correct server and receives the response. To accomplish this task, Transmission Control Protocol uses a three-way handshake to establish the connection, followed by an exchange of requests, and then the client receives the response. After the response is received, the relationship must be closed. This is known as “graceful shutdown” and is handled by TCP. In this way, it provides an essential service to DNS, ensuring that data transmission is reliable and secure.

Conclusion

TCP is an essential part of the Internet Protocol Suite and is reliably used to send and receive data between two points. It provides an invaluable service to network applications with built-in error checking, retransmission capabilities, flow control, and gracefully closing connections. If you’re curious about how TCP works and why you should care, start by understanding its features, applications, and security implications.

Premium DNS: How to get started?

  By

If you are getting many DNS queries for your domain, and your current nameserver or nameservers can’t handle it, you need Premium DNS. It is a service that will facilitate your domain’s DNS resolution and better manage the DNS queries.

What is Premium DNS?

A Premium DNS is a paid DNS service for managing your domains. The difference from a free DNS plan will be in price, performance, additional features, higher limits on resources (NS records, DNS queries, etc.), or even unlimited resources in some cases.

Before you purchase a Premium DNS plan

  • Which market or markets do you target?

Check where the potential DNS providers have their DNS servers. Even the global providers don’t cover the world equally.

  • How many DNS queries per month your DNS service must be able to handle?

There are some unlimited plans, but they might be out of your reach. Check how many queries you need. You can do it with a Free plan and check when you will reach your limits.

  • How many DNS records do you need?

Even Premium plans have limits on the number of DNS records. So yes, you will probably be able to host thousands of records, but still, it is good to know in advance.

  • Do you need any additional features?

DDNS, DNSSEC, load balancing, GeoDNS, etc. There are plenty of useful features that only Premium plans offer. Check what you need.

Compare Premium DNS providers

When you finally know what you need, go ahead and check the Premium DNS providers. Compare their prices and offers. See what works best for you.

Purchase Premium DNS

Now that you have already made your choice get familiar with its interface. Check the menus and how everything works. If you don’t like how it works, usually there is a period with a money-back guarantee.

  • Choose the nameservers you want to use

There will be multiple nameservers available. Start using those that are located in places close to your visitors. That way, the queries will get answered fast, and the performance will be better.

  • Redirect your domain from your registrar or previous DNS provider

Otherwise, the new ones won’t start working properly.

  • Create Primary or Secondary DNS zones

Depending on your needs, you will need a Primary zone or zones in which you can host your DNS records and Secondary DNS zones for better performance.

  • Create DNS records inside the Primary DNS zone.

Inside the Primary zones, you can add the records you need: A, AAAA, MX, CNAME, etc. The Secondary DNS servers will copy the information from the Primary and will offer it to the public.

Activate additional features

Now that everything is working, you can also start using the advanced features that only Premium DNS plans offer.

Activate a DNS monitor to keep an eye on your network and add Failover in case of problems.

Create load balancing methods and increase the performance.

Put attention to security with DNSSEC, DMARC, DKIM, SPF, etc.

Conclusion

Now you know how to get started with Premium DNS. Go ahead and enjoy your awesome new DNS service.
