Bynet

The BYNET is the communication network between AMPs and PE‘s. The PE comes up with a PLAN and passes the plan to the AMPs in steps over the BYNET. The AMPs then retrieve the data requested by the PE and they deliver their portion of the answer set to the PE over the BYNET.

The BYNET provides the communications between AMPs and PEs – so no matter how large the data warehouse physically gets, the BYNET makes each AMP and PE think that they are right next to one another. The BYNET gets its name from the Banyan tree. The Banyan tree has the ability to continually plant new roots to grow forever. Likewise, the BYNET scales as the Teradata system grows in size. The BYNET is scalable. There are always two BYNETs for redundancy and extra bandwidth. AMPs and PEs can use both BYNETs to send and retrieve data simultaneously. Both BYNETs can be used to send a message or to receive a message!
