Force10 Networks Chief Scientist Highlights Importance of Advanced Backplane Design to Support 100 Gigabit Traffic.SAN JOSE, Calif. -- "Providing system-level support for 100 Gigabit One billion bits. Also Gb, Gbit and G-bit. See giga and space/time. Ethernet requires an advanced backplane Backplane of a Hub Cabletron's MMAC PLUS supports a variety of networks, including Ethernet, Token Ring, FDDI and ATM. The modules plug into the backplane, which is an intelligent device used to bridge between the various topologies. The bottom row of sockets is used for ATM, while the top row is used for all the others.

"The backplane is the foundation of a switching or routing system and provides the glue that interconnects all system pieces," said Goergen during the conference that explored the need for 100 Gigabit Ethernet An Ethernet technology that raises transmission speed to 1 Gbps. Used mostly for backbones, the first IEEE standard (802.3z) for Gigabit Ethernet (GigE) was defined in 1997 for use over multimode optical fiber. 802.3z provides full-duplex operation from switch to end station or to another switch and half-duplex using CSMA/CD in a shared environment. In 1999, the 802. interconnects. "If the backplane cannot process traffic at 100 Gig rates, the system cannot support 100 Gigabit ports; it's a single point of constraint." The effort to create a 100 Gigabit Ethernet is underway in the IEEE802.3 Higher Speed Study Group. In conjunction, groups like the Optical Interconnect Forum are working to develop system-level standards to support 100 Gigabit Ethernet. Critical among these system-level requirements is the development of the backplane and transmission channels that ensure communication and processing within the system. "Where existing channels on a backplane are typically 3.125 Gbps, to achieve 100 Gigabit Ethernet throughput, the channel should optimally be 22 Gbps," said Goergen. "This design concept supports not only 100 Gig speeds but also ultra high 10 Gigabit Ethernet densities at line rate." As the 10 Gigabit Ethernet standard resulted in an increase in Gigabit Ethernet port density, the 100 Gigabit Ethernet standard will increase 10 Gigabit Ethernet densities, further driving down the costs of 10 Gigabit Ethernet. Goergen holds 11 U.S. and international patents for his advances on the design and manufacturing techniques of high performance backplanes. This intellectual property is at the core of the Force10 TeraScale E-Series backplane, which has been tested to support up to four 100 Gigabit Ethernet ports per slot.
