In the Broadband usage I see the category "others" present, what TCP/UDP packet types is this

Recently on the network I manage as a volunteer I have seen a large 6GB daily increase in network traffic.
The usage show that this is primarily of the packet type "Others".
What TCP packet type does Others include?
The Network is a very simple one, comprising of an EPOS system that swaps data every 10 mins by FTP with its supplier.
There is another office PC on the network but this only switched on for admin/email use and then off again, there is no WiFi connected to this ADSL router. In the last 10 days I have seen a sudden jump in network usage by an extra 6GB a day.
Any suggestions will be helpful.

Hi John.
Whilst it probably doesn't help too much, the Other category is basically anything that can't be identified in the specific categories listed. Is there any usage showing when all your computers/devices turned off, for example at a weekend?

Gandalf,
Thank you for your reply.
The EPOS server and EPOS web-bridge PC are working 24/7. The web-bridge exports
the database to our supplied and get back database changes for all the online sales item bought
through our website. We are a heritage railway so people can buy their tickets online.
The transfers are by FTP every 10-15mins so I would expect this to be the most predominant packet type.
The large amount of others is suspicious (see my current breakdown). I am tempted to plug my Netbook
into the switch to investigate the packet types
Peak time usage (8am - Midnight) Off-peak usage (Midnight - 8am)
Activity | Peak usage | Off-peak usage | Total usage |
---|---|---|---|
Web | 1.88GB | 599.79MB | 2.48GB |
63.88MB | 0KB | 63.88MB | |
Broadband phonecalls | 10.6MB | 1.03MB | 11.63MB |
Gaming | 0KB | 0.99KB | 0.99KB |
Streaming | 50.27MB | 23.9MB | 74.17MB |
PlusNet FTP | 0KB | 0KB | 0KB |
Peer-to-peer | 0.43KB | 3.03KB | 3.46KB |
Usenet | 0KB | 0KB | 0KB |
FTP (non PlusNet) | 19.13GB | 9.83GB | 28.96GB |
Other | 20.38GB | 9.74GB | 30.11GB |
Total usage so far | 41.51GB | 20.19GB | 61.7GB |
Do you have any suggestions.

I don't imagine automated processes behave differently during daytime and at night so each day one would expect these to record 1 unit during 8 hour off-peak and 2 units during 16 hour peak. The significant usage under Web, FTP (non-Plusnet) and Other follows this pattern suggesting these arise through automation.
When traffic prioritisation was in use the emphasis was on classifying downloads ahead of passing through infrastructure bottlenecks. Upload traffic was generally of smaller volume and had already passed through these bottlenecks by the time it reached Plusnet. One can speculate that perhaps the latter is classed as Other.
With this application is database upload and download volume likely to be similar? I wonder if Other represents upload traffic.
Are you able to count download and upload traffic separately?

David,
Thank you for your reply.
The EPOS uploads 14MB of XML and a small subset of altered records is downloaded (<1MB)
as database updates. I personally think that expired product information is still being exported and need delisting. I'm
avoiding another volunteer IT role of the DB administrator.
I think I need to do a traffic analysis at the router and the switch.
