- We do not want to confuse.
-
- There are two models:
-
- First Model:
-
- The traditional in which the switched network is a cloud, connecting
- two endpoints via a virtual path in which no processing takes place. This
- is the model for connecting a terminal with a data base server.
-
- Second Model:
-
- The proposed, but not yet accepted model, which says that the data base server
- is a messaging layer and the data is scattered widely across the network.
- In this model, a complex query needs to traverse multiple VCI, and the
- construction of the query pattern is optimized over multiple VCI, and the
- searching of data may require parallel propagation across multiple links.
-
- The first model is currently sold by these wonderful switch vendors, and works
- just fine for your problem.
-
- The second model awaits a critical mass of developers who understand its
- operation.
