Network latency refers to the network waiting time, which refers to the round-trip time for a data packet to be sent from the user’s computer to the website server, and then immediately from the website server to the user’s computer. Network delay is one of the factors that affect network speed. So, what does network delay have to do with switches? What caused the network delay? How to measure the network delay of an Ethernet switch? Now please follow JHA TECH to learn how to solve the network delay caused by the Ethernet switch.

Network Delay

What is the network delay in an Ethernet switch?

The network delay of an Ethernet switch refers to the time interval from when the switch receives a data packet to when it starts to copy the data packet to the destination port. Sometimes, when a data packet passes through the device, there is a delay in the switch or router deciding where to send the data next. Therefore, high-bandwidth, low-latency switches have now become the best choice for deploying high-performance networks.

What are the reasons for the network delay?

*The time it takes for a data packet to be sent from the user’s computer to the website server and back to the computer.
* Router or switch errors, because each gateway takes time to check and change the header of the data packet, so the data packet will take a lot of time when it passes through the Ethernet switch.
* Antivirus and similar security programs require time to complete message reassembly and decomposition before sending data packets.
* When data packets suffer storage or disk access delays on intermediate devices such as switches or bridges, storage delays occur.
* Software error on the user side.
*The problem of the transmission medium itself. It takes some time for the transmission medium to transmit a packet from the source to the destination from the optical fiber to the coaxial cable.
*Even if data packets are transmitted from one node to another at the speed of light, there will be delays.
