We've made some estimates for our transaction network... all service transactions (multiple products), network management messages, etc... 30,000 terminals.... 266 TPS, nominal load.

One thing that people sometimes get confused about when they are talking TPS is what they are defining as a "transaction". Some define it as a single message between a terminal and the switch. Some define it as a group of related messages between the terminal and the switch. Some include network management messages, some don't. Some define a transaction as *any* message within their system (for instance, a single message from a terminal might generate 20 internal messages between services/systems).

Our TPS estimate was for individual messages between terminal and host.
