Galileo Technology Ltd. this week will enter the high-end Layer 3-based market with a family of voice/data switch processors that the company claims has a peak LAN/WAN routing performance of more than 40 million packets per second.
In addition to its new GalNet-3 family, Galileo will announce WAN-based uplink chips designed to support several LAN/WAN protocols-including ATM, Gigabit Ethernet, and packet-over-SONET/SDH-in a switch or other system.
The new chips expand Galileo's portfolio of LAN/WAN-based switching and routing applications, including Layer 2, 3, 4, 5, ATM, and packet-over-SONET/SDH. Previously, the company only offered switching chips for lower-end Layer 2 and 3 applications in Ethernet-based networks.
Galileo's new products are a response to the long-awaited convergence in LAN/WAN networks. For example, switch-equipment OEMs, which previously offered data-only systems, are developing a class of switching routers and related products that support voice, data, and video. OEMs are also developing multi-service products that support a number of complex protocols in the same box.
Despite this convergence, the switch-chip market will remain fragmented, with suppliers offering a variety of products for several new and complex requirements, according to Barry Gray, director of product marketing at San Jose-based Galileo.
"There are some people who only want switching solutions for the LAN," Gray said. "And there are other people who want a connection to the WAN."
Though there is a major push toward the WAN, Galileo's core Layer 2-based switching chips are not going away anytime soon, according to Gray. "I believe there's still a strong demand for Layer 2 switching,'' he said. "Layer 3 [and the WAN] simply provides us with more opportunities."
To address these newer markets, Galileo has rolled out the GalNet-3 voice/data switch processors for voice, data, and video traffic on the network.
GalNet-3 consists of three chips: the GT-48510, GT-48520, and GT-48540. The flagship GT-48510 is an eight-port modular device designed for Layer 3, 4, and 5 applications in 10/100-Mbit/s networks.
The GT-48520 is a stand-alone uplink device for use in Gigabit Ethernet networks.
The WAN-based GT-48540 supports 622-Mbit/s applications in ATM and Sonet/SDH networks.
The three chips can be connected via a hybrid crossbar device, enabling OEMs to develop systems that support up to 256 Fast Ethernet ports and 32 ports of Gigabit Ethernet or packet-over-SONET/SDH.
In addition to routing more than 40 million packets/s, the chips support 64,000 IP and IPX routes and contain more than 64,000 Layer 2-based addresses in the media-access-control function. The products also have hardware firewall capabilities and support Virtual LANs.
Galileo's three chips are housed in 329-pin PBGAs. The GT-48510, to begin sampling in January 2000, is priced at $96. The GT-48520, to begin sampling in March, is also $96. The GT-48540, also to begin sampling in March, is $150. All prices are for quantities of 10,000.
