Industrial routers transmit data through the network. However, during the process of data transmission, if the network is unstable, the data packets will be easy to lost.
The following are 4 common problems and solutions for it.
1.Link congestion
During network data transmission, data must be transmitted through multiple links. If one of the links is fully loaded when data arrives, when the link is congested, it must wait to continue sending over the line (this is called queuing).
If a network device is far behind, it won’t have room to wait for new data (queue), so the only thing it can do is drop information.
It can be a headache to hear that data is being “dropped”, but most applications can handle this gracefully, and the user won’t even notice the exception.
The user’s application slows down the transmission and retransmits the data when it knows a packet is lost. The
Solution For Link Congestion
Increase the bandwidth of congested links.
Prioritize real-time traffic when enforcing Quality of Service (QoS). While less helpful on congested links, applications such as voice or video can be prioritized to reduce the chance of loss.
2.Line Failure
If the hardware is not working properly, this usually results in error messages in the device console or system logs.
If there is a link problem, it is usually a fault with the interface, which can be seen on both copper and fiber optics.
Solution for Line failure
The faulty hardware must be replaced or the faulty link repaired.
The best way to determine the root cause of packet loss is through network assessment and detailed troubleshooting.
3.Network Software Error
These errors can cause new features to not work properly during deployment, and troubleshooting begins once performance issues are detected. These types of problems can often be discovered by using system logs and packets.
Solution for Network software error
Upgrade the software on the affected devices.
4.Device Performance
If the device bandwidth is sufficient, the industrial router or industrial switch cannot keep up with the traffic, and packet loss will also occur.
Suppose the link of the data transmission equipment is upgraded from 1Gb to 10Gb, because the traffic report shows that you are fully loaded at the peak time of the day, and after the upgrade your graph shows the bandwidth as high as 1.5Gb, you still have network performance problems.
The problem may be that the device is not keeping up with the traffic and has reached the maximum throughput the hardware can provide.
When traffic arrives at the industrial router, but the industrial router’s CPU or memory cannot handle the additional traffic at its maximum, this will result in packet loss for all traffic that exceeds capacity.
Solutions for Device Performance
Replaceable hardware must be used for new appliances that can handle maximum throughput, or additional cluster hardware may be used to increase throughput.
