How to setup frequency control?

[chanro4]

And how about the Bandwidth control? Is it set in web client side? Which function should be used? (is it setRequestedBufferSize(size) )

Bandwidth Control
For each user a maximum bandwidth can be allocated, dedicated to the streaming channel, For example, if it is required that a certain user cannot exceed a bandwidth of 10 kbps, Lightstreamer will filter the data in such a way as to ensure that the streaming connection for that user always remains below 10 kbps.

the bandwith settings follows the same pattern, the client can ask to limit its bandwidth (setRequestedBufferSize is the correct method) but the server has always the right to limit it further (see getAllowedMaxBandwidth). Note that bandwidth applies to the whole connection.


about the filtering question, Lightstreamer filters the updates on the basis of the subscription mode. If the frequency of the feed is too high the server may merge updates, queue them and, if the queue is full, drop them. On some cases dropped events are notified to the client (see onLostUpdates)

Check out section 3 of the "General Concepts.pdf" file available under LS_HOME/DOCS-SDKs for a better understanding on the logic that drives the filtering.
