Seeing that this post is asking about PlusNet and essentially how they perform, I'd like to ask a question.
Looking at those detailed speed vs time period charts that PlusNet show for their packages, are those speeds in practice generally held up. Or can there be times when say a throttled speed of say stated at 128Kbps in their chart, actually goes lower than that? So in the main do PN stick accurately to going NO lower than the advertised throttled speeds?
The speed is a maximum of 128Kbps, not a minimum. Depending on which protocol is used, packets are
prioritised on the network, then either forwarded or
dropped by the network management.
All the information is provided in the links, for example; the Value package
rate limits the Usenet protocol to 128Kbps between 2pm-4pm, if you were connected to
PTN-AG1 Plusnet 3 at that time today, your 128Kbps bandwidth was possibly losing 13% of packets, therefore reducing the 128Kbps maximum rate limit. Usenet is classed as
Best Effort on the Value package, they are the first packets to be dropped.
You will hear Plusnet subscribers talk of Gateway Hopping, as reconnecting may change Gateway to a less busy one, ie one which is dropping less packets.
It is complicated, but in short, depending on protocol priority, the maximum speeds may not be achievable if packet loss on the Gateway is high.
