If you consider network as one of the important aspects for your business, then you should never allow network downtime, at any case. You can monitor your network, based on various aspects. You need to recruit a network administrator, for monitoring the functioning of the network. If your company is small, and you feel there is no requirement for a network administrator for your network, then you need to know at least certain information about the basic metrics of the network. Metric refers to the performance of the network. To make sure that you want to reduce the downtime of the network, you should configure some test on the following metrics:
· Round trip time (RTT): RTT is one of the metrics, which provides you information about the time that is taken for a packet to reach the destination, and the vice versa. You need to know about the ideal time taken for a packet, to reach the destination. Businesses like eBay and flipkart must have their RTT monitored for any latency, as these businesses mainly deal with online sales, online transactions, and so on. Depending upon your requirement, you can have some tolerance over RTT.
· Packet Loss: Packet loss is one of the metrics, which provides you information about the total packets lost, from the source to destination. For example, consider that you are sending a file from source A to source B, and if there is packet loss of over 80%, then the file may fail to reach the destination. You should not allow packet loss on your network, and you have to monitor it regularly.
· Jitter: Jitter is one of the metrics, which provides you information about the discrepancies in the network. Jitter is mainly calculated for real time applications, to check the performance of audio and video conferences. There are two types of jitter. They are positive jitter and negative jitter. If a packet takes more time than the ideal time, to reach the destination, then it is the positive jitter. If a packet takes lesser time than the ideal time, to reach the destination, then it is the negative jitter. In a network, you should not allow either positive jitter or negative jitter. If your business deals with audio and video conferencing, then you should maintain the ideal jitter.
· Mean Opinion Score (MOS): MOS is one of the metrics, which provide information about the rate of human voice quality. The rate ranges from 1 to 5, where 1 denotes the poor quality and 5 denotes the 5 quality. MOS is also mainly calculated for real time applications, to check the voice quality in both audio and video conferencing.
After you configure the test, make sure to check with the result of the metrics. There are many applications available in the market, which enable you to monitor your network and get results to check with the discrepancies.
