REP Port Setup |
REP, or Retry Enhanced Protocol, is a custom designed protocol for reliably transferring data packets from the NetRS to one or two external client programs. The protocol has two objectives:
The REP protocol is based on SCTP (Stream Control Transfer Protocol), a standard networking protocol for the semi-reliable transmission of streaming data. SCTP allows the same connection to carry several channels of information. REP defines three channels:
You can create an REP port from the I/O Port Summary page by selecting Create New REP Port. You must enter an REP Port Number between 1024 and 65535. You can choose whether to use Client Authentication when clients attempt to make connections. You can also set the service-specific parameters. Only the Binex streaming service is supported on an REP port.
Only one REP port definition is allowed. If a new REP port is defined, any previously defined REP port will be deleted.
Using an REP stream requires an external client program which establishes a connection to the REP port, accepts the Realtime Data, monitors which packets have been received, manages retry requests, etc. The client program is also responsible for directing the received data to other realtime applications or to longterm storage.
