Re: Retransmissions request on UDP for ITCH

Carlos Hernández <carlos3.14@...>
 

Thanks so much Frank!

Honestly, we are skidding on a stupid c networking detail.  The spec asks me to open a socket to receive both the multicast UDP packets and the retransmissions (still UDP but unicast) while using the same socket to send the resend request. 

How would I go about opening such socket?

Thanks for everybody's time.

Hi Carlos,

 

This your own feed handler I take it? You writing it as an app or as a MAMA bridge?

 

Note I can’t share any proprietary Vela feed handler retransmission code if that’s what you’re asking… Happy to help on the MAMA side though.

 

Cheers,

Frank

Subject: [Openmama-dev] Retransmissions request on UDP for ITCH

 

Hi folks, 

 

I'm writing a feedhadler and the retransmission request from the feed handler to the feed on ITCH 4.1 is causing me headaches. 

 

Anyone has any pointers on possible source code for this use?

 

Cheers
