I once performed a network performance assessment for an organization. They were buying Mbps link capacity from their ISP but the users on the network were struggling to connect to the Internet effectively. Upon investigation, we discovered that while their ISP was truly giving the agreed upon Mbps, the edge device was only providing 30Mbps to the network! Apart from the fact that this organization had wrongly terminated the link on a FastEthernet interface which gives a theoretical speed of Mbps but much lower practical speed , that interface was also faulty.
By moving the ISP link to another interface we used a GigabitEthernet interface instead , the performance problem was solved. In another organization I consulted for, a network of about 10 users had poor browsing experience even with the 4Mbps link they were getting from their ISP. Ideally, this capacity should have been enough because the users were not doing anything heavy on the Internet — just emails, web searches, and normal user activities.
Other security attacks that can result in network congestion include viruses, worms, and Denial of Service DoS attacks. Feeling the effects of network congestion is one thing but actually confirming that a network is congested is another. In this section, we will look at some activities that can be performed to confirm the congestion of a network.
One of the fastest ways to check if a network is congested is to use Ping because not only can it detect packet loss , it can also reveal delay in a network i. Using a tool like MTR which combines ping and traceroute can also reveal parts of the network where congestion is occurring. A tool like iPerf can be very useful in determining performance issues on a network, measuring statistics like bandwidth, delay, jitter , and packet loss. In the same way, tools that monitor bandwidth can reveal network congestion especially during a security attack or if a particular host is using up all the bandwidth.
You can read this article for more information about performing a network performance assessment. In this article, we have discussed network congestion and how it affects user experience. We have seen how causes such as over-subscription, faulty devices, and security attacks can result in network congestion. We have also discussed the effects of network congestion including generally poor user experience, packet loss, and timed out connections.
Finally, we have discussed how to troubleshoot congestions in a network and highlighted some things that can be done to fix these issues. Network Congestion Just like in road congestion, Network Congestion occurs when a network is not able to adequately handle the traffic flowing through it.
Over-Utilized Devices Devices such as routers, switches, and firewalls have been designed to handle certain network throughput. Faulty Devices I once performed a network performance assessment for an organization.
Security Attack In another organization I consulted for, a network of about 10 users had poor browsing experience even with the 4Mbps link they were getting from their ISP. From a technical perspective, the effects of a congested network include: Delay : Also known as Latency, Delay is the time it takes for a destination to receive the packet sent by the sender. For example, the time it takes for a webpage to load is a result of how long it takes for the packets from the web server to get to the client.
Another evidence of delay is the buffering you experience when watching a video, say on YouTube. Packet Loss : While packets may take a while to get to their destination delay , packet loss is an even more negative effect of network congestion. This is especially troubling for applications like Voice over IP VoIP that do not deal well with delay and packet loss , resulting in dropped calls and Call Detail Records , lag, robotic voices, and so on.
Timeouts : Network congestion can also result in timeouts in various applications. Since most connections will not stay up indefinitely waiting for packets to arrive, this can result in lost connections. Troubleshooting Network Congestion Feeling the effects of network congestion is one thing but actually confirming that a network is congested is another.
Ping One of the fastest ways to check if a network is congested is to use Ping because not only can it detect packet loss , it can also reveal delay in a network i. LAN Performance Tests A tool like iPerf can be very useful in determining performance issues on a network, measuring statistics like bandwidth, delay, jitter , and packet loss.
Decongesting a network The fix for a Congested Nnetwork will Depend on the Cause: For oversubscribed links, you may need to purchase more bandwidth from your service provider. Some service providers also allow you to temporarily boost your bandwidth for a small fee. You may also want to implement Quality of Service QoS features which will ensure that even in the event of congestion, critical applications can still function.
A poor network design can be more difficult to fix since the network is probably in use. For such cases, incremental changes can be made to improve the network and remove congestion. Although users will not be able to claim airdrop tokens from every campaign, it provides an overview of which ones are currently active. It is a handy feature for those who want to check eligibility for certain airdrops, although it does not seem to include future events.
One intriguing feature on Etherscan is the Verified Contracts segment. It shows all smart contracts on the Ethereum blockchain that have a verified source code. Not all smart contracts fall into this category, making it easier for users to determine if they should interact with a specific contract. It is also possible to manually look up the contract address and determine if it has been verified.
That process works the same way as looking up a wallet address, although users will see the name, compiler version, and whether a security audit has been performed. CoinMarketCap News. How To Use Etherscan. Table of Contents. What Is Etherscan? By Andrey Sergeenkov. Table of Contents What Is Etherscan? Other Features on Etherscan. The whole saga played out in true crypto fashion, with the hacker embedding messages in transactions on Etherscan.
As blockchain technology and cryptocurrencies are gaining popularity every day, it becomes possible for anyone to keep tabs on particular networks and their overall activity with the right tools. Blockchain explorers are potent solutions to identify transactions, look up wallet addresses, and so forth. For the Ethereum network, Etherscan is such an explorer, although its functionality goes much further. The core functionality of Etherscan is the same as any other blockchain explorer.
It is possible to look up transactions, wallet addresses, smart contracts on Ethereum, and so forth. One can access all of the functionality through the search bar or by navigating the menu options at the top. Thus, anything one wants to learn about the Ethereum network is at one's fingertips through Etherscan.
The easiest way to look up a transaction through Etherscan is by using the transaction ID. However, if you do not have it or don't know where to find it, entering one of the two wallet addresses involved in the transaction will work too. Once the transaction ID or address is entered into the search bar, Etherscan will depict the details, including transactions, balances and so forth.
The Ethereum network uses gas — paid in Ether — to complete transactions. It is Etheruem's transaction fee, although gas works a bit differently. There is no upper limit on transaction gas requirements, as network congestion can drive this number up rather quickly. Thus, a higher gas price equals a higher transaction cost. Moreover, transactions with lower gas prices can fail, as miners may not pick them up.
Through Etherscan, users can find the top tokens for each standard, their contracts, trading volume, price changes, market cap and the number of holders. Every token is clickable to look at it in more detail, to see transactions or other features. Non-fungible tokens are incredibly popular on the Ethereum blockchain. Users who buy these NFTs can see their assets on Etherscan, although it will only show as a token and not as the actual art that is associated with the token.
Users will need to use other services, such as the OpenSea marketplace, to see the whole art, among other options. Etherscan has no functionality to depict the art, yet it will show the token ID, the project it belongs to, its transaction record, and the smart contract interaction.
“So if Shiba Inu generates a lot of traffic, it increases network congestion and contributes to more ETH being burned,” he said. While speed and throughput are important, it is essential that scaling solutions Transaction speed suffers when the network is busy, making the user. Congestion and fees on the Ethereum network are driving many developers of key catalysts that investors see as bullish for this network.
