This becomes even more likely on long-distance internet connections because the packets have farther to go and, by extension, more room for error. Unsuccessful packets slow down network speeds, cause bottlenecks, and throw off your network throughput and bandwidth.
Packet loss can also be expensive. There are many causes of packet loss, most of them unintentional. The number one cause of packet loss is network congestion.
Think of packets traveling across your network like cars going down a highway. At certain points in the day, like during rush hour or after lunch when all the employees in a large company are going back to their desks, there are too many cars on the road. Things get even worse when a four-lane highway narrows into a two-lane road, and a lot of cars are looking to merge at the exact same time. Highway traffic is a fact of life and so is packet loss. When network traffic hits maximum capacity, packets will have to wait to be delivered.
Unfortunately, packets are the first things to get left behind when a network is trying to catch up with traffic and the connection can only handle so much. Luckily, most software today will circle back for those discarded packets by automatically resending the data or slowing down transfer speeds to give each packet a chance to make it through. Glitchy, old, or otherwise outdated hardware can significantly weaken your network. Firewalls, routers, and network switches all take up a considerable amount of power.
Unchecked bugs in your system can disrupt network performance and prevent it from sufficiently carrying packets. Sometimes rebooting your hardware will solve this, but since bugs are often introduced during hardware updates, the whole thing will need to be patched.
Simply put, this means your system is running at a higher capacity than it was designed to handle. In fact, packets on overutilized devices sometimes make it to their destinations, but by then the network is too weak to process the packets and send them back out. Many devices have buffers in place to put packets in holding patterns until they can be sent out. However, these buffers can get filled up quickly and excess packets are still dropped.
We also cannot ignore the possibility of someone deliberately tampering with your network and causing packet loss. Packet drop attacks have become popular with cybercriminals in recent years. Essentially, a hacker gets into your router and tells it to drop packets.
If you notice a sudden drop in packet success or a significant slowdown in network speed, you could be in the midst of an attack. Hackers execute a denial-of-service attack by flooding the network with too much traffic for the network to handle, and it crashes.
The attackers then take advantage of this vulnerability. Invest in a SIEM solution , create a disaster recovery plan, update your firewall and, as always, keep yourself up to date on the latest antivirus software.
Such attacks are rare—there are more common causes out there for packet issues. Many IT administrators cobble together a networking monitoring system out of different tools. Without a comprehensive, seamless network monitoring solution, opportunities to stop or prevent packet loss fall through the cracks.
Wondering how to reduce packet loss? Zero percent packet loss is unachievable because the things causing it, like network issues, too many users, or an overloaded system, are bound to pop up. Any solutions recommended here or elsewhere are ways to help fix the problem after the fact, not prevent them from occurring.
The key to preventing or lessening the impact of packet loss is network visibility. A problem you can see is a problem you can solve. The tools listed below, in addition to boasting features specific to packet loss, can be used to give you a more comprehensive view of your network.
Both tasks are accomplished with networking monitoring best practices. NPM is an excellent choice for admins who have to keep watch over a large systems environment—the hop-by-hop packet path maps are especially useful, as you can quickly see if the problem lies inside or outside the network, and the tool provides the info you need to start addressing the issue quickly. This function highlights the problem links in red, making troubleshooting easy.
Also, NetPath displays each router and switch in the network route as a node. If you hover over the node, it pulls up the latency and packet loss statistics. Along the same lines, the LUCID logical, usable, customizable, interactive, drill-down user interface in NPM gives you a complete summary of all network activity, device status, and alerts, so you can see how your system is doing without having to toggle between different screens.
Bonus: NPM is fully customizable. Packet loss means low-quality video, which means frustrated users which means low-adoption rate or worse, in the case of telemedicine, unhappy patients. Measuring current packet loss, not total, would give the end user a much more pleasant experience as opposed to an overall, it was ok call. Packet loss happens. But, in order to truly help prevent a high percentage of packet loss in the future, implementing a modern packet loss solution, is crucial.
By taking the next steps to implement a modern packet loss solution and taking the further step of implementing Vyopta, organizations will start to see that packet loss standard is much higher in the long run. Provide customers with the leading solutions that monitor and optimize their collaboration environments.
Vyopta aligns with industry leading technology vendors so our customers can monitor networks of any size and complexity. Troubleshooting packet loss: How much is an acceptable amount? Dec 19, Video Conferencing. How much packet loss is acceptable? How do you calculate packet loss?
Rethinking Packet Loss A more useful metric is current packet loss, or for historical analysis — peak packet loss.

Data travels at very roughly , miles or , kilometers per second, or miles km per ms millisecond over a network connection.
With traceroute, we have to send the data there and back again, so roughly 1 ms of latency is added for every 60 miles 96km, although with the level of accuracy we're using here, we should say 'km' of distance between you and the target.
Packet Loss Packet loss is almost always bad when it occurs at the final destination. Using PingPlotter to measure latency and packet loss If you've determined that your latency is out of the normal realm, and if you're seeing problems with some aspect of your connection unexpected slowdowns, disconnects, or that you are often forced to 'retry' , then looking at the PingPlotter data should help you understand the source of the problem.
