low bandwidth network support

Can we consider RTI DDS as a solution for a low banthwidth (25K bytes/sec) for multiple clients data distribution of messages (up to 10K)? (latency is not importent)

Determining of lifespan-expired for samples at writer side

Hello,

I have a reliable writer configured with:
lifespan QOS of 60 sec.
history size: 30000, keep last

 

The transport is low bandwidth, and on peak situations samples may be produced at higher rate than network capacity.

I would like to be able to log any sample (by the sample's ID field), in case the writer had to drop it before sending, due to expired lifespan.

Is this possible via writer listener callback or some other machanism ?

Batch never flushed (with non infinite delay)

Hello

I configured a DataWriter with max_flush_delay of 2000000 nanosec (2 milsec). I write to the DataWriter about 600 samples for 30 sec and then a long quiet period, but the last few samples are never received by the DataReader.

When I disable batching, all samples are received as expected.

I am using Connext 5.1 under Windows x64. I saw the following fix in the 5.1 Release Notes, but still the problem still exist.

Serialization / Deserialization of a DDS data sample

Hello,

How can I take advantage of RTI's APIs in order to convert a data sample object which I read using a DataReader into a byte array and vice versa (in Java)?

I would like to save the binary serialized object to file and then be able to read it again into object. 

 

Thanks

David
