What is Myricom DBL API?

DBL™ is an optional, user-level, software interface for accelerating applications whose performance depends on network latency. Examples of applications that will benefit from DBL™ include algorithmic financial trading and others where reduced network latency is beneficial.

Does FIXAntenna support DBL UDP API acceleration?

Yes, FIXAntenna supports DBL UDP API acceleration for following Market Data adaptors:

    • Bats MD Adaptor 
       
      To use DBL UDP API acceleration in Bats MD Adaptor you need to set the property Bats::RuntimeParameters::readerType.

      Example:

      Code Block
      languagecpp
      titleSource Code
      struct AppListener : Bats::ApplicationListener
{
//your implementation of Bats::ApplicationListener interface
};

int main( int argc, char const* argv[] )
{
...
	//init FIX Engine
	Engine::FixEngine::init( );
 
	AppListener appListener;
 
	Bats::ApplicationOptions options;
	//set other options
	...
	//Enable using of DBL UDP API acceleration
    options.params.readerType = Bats::IncrementReaderType::MyricomDBL;
    options.params.incrementalThreads = 1;

	//create an application
	Bats::Application* app = Engine::FixEngine::singleton()->createBatsApplication(options, &appListener);
...
}

{
public:
	//your implementation of Bovespa::BovespaApplicationListener interface
    BovespaClientApplicationListener(){}
    ~BovespaClientApplicationListener() {}
    virtual void onError( std::string const& errorMsg );
    virtual void process( Engine::FIXMessage const& msg,std::string const & channel_id );
    virtual void onConnectToFeed(std::string const& feedId) {}
    virtual void onDisconnectFromFeed(std::string const& feedId) {}
};
 
int main( int argc, char const* argv[] )
{
...
	//init FIX Engine
	Engine::FixEngine::init();
 
	//Create an application listener
    BovespaClientApplicationListener appListener;

	//initialize BovespaApplication parameters
    Bovespa::BovespaApplicationParams params;
	//set other options
	...
	params.transportType_ = Bovespa::BovespaApplicationParams::MyricomDBL;
    
	//Create an MD application
    Bovespa::BovespaApplication* application = Engine::FixEngine::singleton()->createBovespaApplication( params, &appListener);
...
