The physical network on board a yacht has grown massively in terms of roles and complexity over the years. Ten years ago, you would have seen a separate AV network, a separate internet network (possibly with some wireless access points), a separate telephone PABX network etc etc. All independently wired and discrete with very limited integration of these different networks. Today, all equipment on board is generally IP based so can operate across both a wired and wireless network. The actual demand for internet data both in terms of volume and bandwidth has also rocketed. 10 years ago, a yacht could simply connect to the internet via a dial-up for a few minutes 2 or 3 times a day using a few MB of data. Today we are seeing yachts demanding (and using) 10 GB data a day and have had one yacht use 100GB in a day!
Bandwidth and data is expensive and unfortunately is not finite – unless you have a very generous owner! It is essential to be able to ‘see’ both what data is available, and also who or what is using it. This is the essence of bandwidth management.
