Connecting to Multiple Services simultaneously

We are currently using the RFA 8.2 C++ API to consume market data and would like to clarify some functionality. Is it possible for a consumer application to simultaneously connect to multiple services on TREP/ADS, such as IDN_SELECT etc. and send requests to these different services for different symbols?

Can you also provide the multiple services available and purpose of each one?

    Thank you for reaching out to us.

    ADS can advertise multiple services via source directory messages. Please refer to the RFA developer guide in section14.2.3 regarding Requesting a Directory.

    Then, the application can specify a service name in an item request message. 

    Handle* StarterConsumer::sendItemRequest(const RFA_String& itemName, const RFA_String& serviceName, UInt8 indicationMask, UInt8 msgModelType, Int32 interType)
    {
        Handle* pHandle = 0;
        ReqMsg reqMsg;
        AttribInfo attribInfo;


        reqMsg.setMsgModelType(msgModelType);
        reqMsg.setInteractionType(interType);


        attribInfo.setNameType(INSTRUMENT_NAME_RIC);
        attribInfo.setName(itemName);
        attribInfo.setServiceName(serviceName);


        reqMsg.setAttribInfo(attribInfo);

    You can only specify only one service in an item request message.
