Receive Process and Port Configuration
Multiple Port Configuration
The workflow library has the capability to configure multiple ports. This allows to deploy a single receiver with multiple ports. In another word, this will allow a single receiver to receive data for a single SPEAD stream coming from multiple processes.
Now, assuming each sender sends data for 1 channel and all baselines, then we’ll want to have as many ports as
channels on the receiver side. For cbf-receive, a single receiver process can receive on multiple ports already,
and this is configurable via
To make sense of multiple ports, the port map was required to be updated from a three-value list (ADR-10) to a four-value list. The four value defines the increment of the port number.
For example, if we set
reception.receiver_port_start = 9000 and
reception.num_ports = 3 ,
max_channels=1 then the resulting port_map would look like:
"port": [[0, 9000, 1, 0], [1, 9001, 1, 1], [2, 9002, 1, 2]]
