Our client wants to communicate via IP packets.
Our responsibility is to take these packets and if necessary assemble them if the data is in more than one packet, reformat, connect to a queue manager and place the this message on a queue to be picked up by our own service/listener/application, get processed and then sent back to the client in the original format of an IP Packet.
Is there an WMQ/WMQI application or plug in that can accomplish this?
Is there a WMQ/WMQI component that can read, parse, assemble, convert these packets? |

Unless the client already knows what they want to put in the IP Packets...
You could tell them that a regular MQSeries client works this way... 
Or you might be able to use the Real Time nodes in WBIMB v5. I haven't worked with them yet, so I don't really know what they do or how they do it, but what little I've seen seems like what you want.

jeff,
Would the q program included in the MA01 support work for us?
Here is the description:
Q is simple pipe line program which takes messages from one source and
outputs to a target. The operation of the 'pipe' is controlled by
switches to the program. The source and target can either be the
console or an MQSeries Queue. Since input/output can be taken from
stdin/stdout these can also be files. Two instances of Q can therefore
be used to implement a primitive file transfer program.
Since the messages are IP packets, would this program not work because it is neither a console or MQSeries queue/ |

No. The Q program in MA01 is simply an MQSeries application.
Like I said, if your client has specific IP level packet designs in mind, then you will have to write a custom MQ adapter (or possibly, "merely" write a new Message Channel Agent as mentioned in the other version of this thread).
If your client does not have specific IP level packet designs in mind, then you can tell them that MQSeries already does "IP Packet" level communications for them.

Jeff,
What do you mean specific IP level designs in mind?
Are there online examples of MQ adapters?
On a scale of 1-5, with 5 being the most difficult, how difficult would it be to build a new MCA?
"If your client does not have specific IP level packet designs in mind, then you can tell them that MQSeries already does "IP Packet" level communications for them." If this is the case is what WMQ component can 'pick up' an IP packet, reformat it to mq message and put it on a queue? |
