Issue 2919: TcPdu User and Provider interfaces (incorba-ftf)
Source: Ericsson (Mr. Neill Jones, etlnljs(at)etlxdmx.ericsson.se)
Nature: Uncategorized Issue
Severity: 
Summary: As the interfaces currently stand, there is a minimum of 5 CORBA calls
per transaction
1. either TcPduProvider::get_dialog_id
    or TcPduProviderFactory::create_tc_pdu_provider
2. TcPduProvider::invoke_req
3. TcPduProvider::begin_req
4. TcPduUser::end_ind
5. TcPduUser::result_l_ind

Given that a CORBA call is about 1 millisecond on average,
this makes for a highly inefficient interface from a high-performance
perspective,
and renders the distribution of these interfaces undesirable, and the
use of the TcPduProvider/User interfaces unlikely in a real system.

Ideally this should be reduced to a minimum of 2 CORBA calls, one for a call
going out, and one for the reply.

Hi all

Subject: TcPdu User and Provider interfaces

As the interfaces currently stand, there is a minimum of 5 CORBA calls
per transaction
1. either TcPduProvider::get_dialog_id
    or TcPduProviderFactory::create_tc_pdu_provider
2. TcPduProvider::invoke_req
3. TcPduProvider::begin_req
4. TcPduUser::end_ind
5. TcPduUser::result_l_ind

Given that a CORBA call is about 1 millisecond on average,
this makes for a highly inefficient interface from a high-performance
perspective,
and renders the distribution of these interfaces undesirable, and the
use of the TcPduProvider/User interfaces unlikely in a real system.

Ideally this should be reduced to a minimum of 2 CORBA calls, one for
a call
going out, and one for the reply.

It is suggested that the current definitions of these interfaces is
impractical
and should be completely revised.
