December 13, 2004 Santa Clara, CA -- Passave, a provider of Ethernet passive optical networking (EPON) semiconductors for fiber to the home (FTTH), has announced availability of a programmable dynamic bandwidth allocation (DBA) engine along with its new Plato DBA algorithm.

The need for programmable DBA is directly linked to the changing nature of Internet applications. DBA algorithms are optimized for different traffic patterns and applications. Passave says its programmable DBA engine provides carriers with the only option for high-performance DBA that does not require forklift network upgrades for algorithm changes. The engine's programmability enables carriers to adapt fielded equipment to changing network usage and customer applications, thereby protecting their investments in FTTH.

According to Dror Sal'ee, vice president of Passave, the engine can be programmed with algorithms developed by the systems vendor or via programs Passave provides. The Plato algorithm, the company's newest offering, is designed to improve upstream utilization, reduce upstream delay, and deliver improved quality of service, supporting triple-play applications as well as legacy TDM traffic emulation over advanced Gigabit EPON systems. The programmable DBA engine is integrated into Passave's PAS5001 optical line terminal (OLT) device, enabling carriers who already have Passave-based EPONs to utilize the Plato algorithm immediately.

Passave's programmable DBA engine is already in field deployments, including in Japan.
