We present an overview of the design of event building in the BABAR Online, based upon TCP/IP and commodity networking technology. BABAR is a high-rate experiment to study CP violation in asymmetric e{sup +}e{sup {minus}} collisions. In order to validate the event-builder design, an extensive program was undertaken to test the TCP performance delivered by various machine types with both ATM OC-3 and Fast Ethernet networks. The buffering characteristics of several candidate switches were examined and found to be generally adequate for our purposes. We highlight the results of this testing and present some of the more significant findings.
