Allayer possesses key technologies that enable the development of very high performance enterprise switches and routers serving the workgroup and enterprise LAN and LAN/WAN connectivity markets.

To meet the need for higher data throughput in the enterprise network, smarter switches and faster links are required. As the average data rate has increased from 1Mb/s to 10Mb/s to 100Mb/s and today's Gigabit per second, Allayer provides key ICs that enable system OEMs to develop Fast Ethernet and Gigabit Ethernet switches and routers.

Allayer has the high bandwidth switching and packet processing technology, the proven RoX™ architecture, proven fiber optics technology and the systems expertise to build the next generation IC components that will drive high bandwidth enterprise switching systems.

The RoX™ Bus Architecture:

The RoX family is a library of Fast Ethernet and Gigabit Ethernet switching building blocks. The RoX bus is a low-cost link between devices that enables port expansion, management information collection, and the addition of routing capabilities to a switch.

The RoX bus operates in a ring configuration in which up to four switch engines, one management device and one router IP processor engine can be connected on a single ring. One ring can support up to 32 Fast Ethernet or 8 Gigabit Ethernet switch ports or a combination of the two. Multiple rings can be linked together using expansion interfaces to build very large port count switches. The original RoX bus operates at up to 75 MHz and can support a throughput of 9.6 Gigabits/sec, the RoX-II bus operates at up to 100 MHz and provides 12.8 Gigabit/sec. throughput.

Using the RoX™ enterprise bus architecture, highest bandwidth, scalable, and feature-rich systems can be easily developed.

Allayer produces switching ICs and Layer 3/4 packet processors that provide a building block approach to high performance, feature-rich enterprise networking systems.
