EMS connection between:

Since multiple small handshaking and acknowledgement XML messages are exchanged, sizing activities should focus on the relatively large ESIResponse messages issued by Windchill for each product data publishing activity. Each of these XML instances contains all of the CN, BOM, part, document and manufacturing objects data to be published to the distribution targets in a single, composite message.

TIBCO Rendezvous messaging within the BusinessWorks

Rendezvous messages traverse networks using a proprietary protocol based on UDP and occasionally TCP. Generally, the defaultWindchill ESI and TIBCO messaging settings should provide adequate performance and work out well for you. However, using broadcasting protocols might cause performance concerns for network administrators. TIBCO provides a number of alternatives to alleviate these concerns. Refer to the TIBCO Rendezvous Administration manual for further information.

Rendezvous connection between BusinessWorks and the adapters distribution targets

Windchill ESI sends only a subset of the data from the original Windchill composite XML message to the distribution target adapters. Typically, the product structure is created in the distribution targets on a part-by-part or object-by-object basis. In other words, the BusinessWorks interface with Windchill is high-volume, low frequency, while the BusinessWorks interface with the distribution target adapters is low-volume, high-frequency.

Connection between the adapters and the distribution targets

These connections are typically TCP-based. As a general rule, the network traffic load between BusinessWorks and the adapters is less than the load between the adapter and the distribution targets. Therefore, when possible, we recommend co-locating the adapters and distribution targets on the same LAN.
