This process reads the - connection_config and consumer_config files: - - 1. The connection_config file is used to establish the "physical - configuration." It tells the Gateway what connections - to establish with particular hosts using particular - ports. - - 2. The consumer_config file is used to establish the "logical - configuration." It tells the Gateway how to forward - data coming from "sources" to the appropriate - "destinations." -Peer - - -- The test driver programs that must be started *before* the - Gateway. To do anything interesting you'll need at least - two Peers: one to supply events and one to consume events. - In the configuration files, these two types of Peers are - designated as follows: - - 1. Supplier Peers (designated by an 'S' in the Gateway's - connection_config configuration file). These Peers are - "suppliers" of events to the Gateway. - - 2. Consumer Peers (designated by an 'C' in the Gateway's - connection_config file). These Peers are "consumers" of - events forwarded by the Gateway (forwarding is based on - the settings in the consumer_config configuration file). - -RUNNING THE TESTS - -To run the tests do the following: - -1. Compile everything (i.e., first compile the ACE libraries, then - compile the the Gateway directories). - -2. Edit the consumer_config and connection_config files as discussed - above to indicate the desired physical and logical mappings. - -3. Start up the Peers (peerd). You can start up as many as you - like, as per the connection_config file, but you'll need at least - two (one to supply and one to consume). I typically start up each - Peer in a different window on a different machine. The Peers - should print out some diagnostic info and then block awaiting - connections from the Gateway. - -4. Start up the Gateway (gatewayd). This will print out a bunch of - events as it reads the config files and connects to all the Peers. - Assuming everything works, then all the Peers will be connected. - If some of the Peers aren't set up correctly then the Gateway will - use an exponential backoff algorithm to attempt to reestablish - those connections. - -5. Once the Gateway has connected with all the Peers you can send - events from Supplier Peers by typing commands in the Peer window. - This Supplier will be sent to the Gateway, which will forward the - event to all Consumer Peers that have "subscribed" to receive these - events. - - Note that if you type ^C in a Peer window the Peer will shutdown - its handlers and exit. The Gateway will detect this and will start - trying to reestablish the connection using the same exponential - backoff algorithm it used for the initial connection establishment. - -7. When you want to terminate a Gateway, just type ^C and the process - will shut down gracefully. - -Please let me know if there are any questions. - - Doug - - schmidt@cs.wustl.edu |
