Controlling packet loss with the Allegro Network Multimeter

Packet loss

Packet loss is disruptive to the network because it causes delays. TCP protocols establish reliable data transmission but disguise the effects of packet loss. TCP ensures that data is transmitted on the basis of a concept called "sliding window". This mechanism controls the transmitted byte sequences and the received acknowledgements. With the help of sequencing, a receiver can inform the sender about missing data (e.g. packet loss).

Bandwidth and Congestion

In the case of network-related application performance problems, we usually think of limited bandwidth and network congestion as possible causes. We may assume that higher speed and less traffic will solve all issues. In practice, the elimination of network-related performance problems is one of the most complex tasks in data communication.
