GalNet™-2+.   Utilizing the same architecture as our GalNet™-2, our GalNet™-2+ devices add integrated memory and support for advanced Quality of Service, or QoS, via support for packet prioritization. GalNet-2+ Ethernet controllers support the native QoS requirements of Windows 2000, which is providing an important catalyst for the development of multimedia applications. GalNet-2+ devices integrate both the packet and control memories into the switch controller, providing a high level of integration, low chip-count and advanced features. The GalNet™-2+ switches are combined using GalNet™-2 crossbars to enable the development of high-performance end products, such as 1U rack-mount stacking switches and modular systems with up to 256 Fast Ethernet ports or 32 Gigabit Ethernet ports.

®-2.   Our GalNet®-2 family comprises more than twenty products, from Fast Ethernet and Gigabit Ethernet switch controllers, to G.Link crossbars and bridges — all offering what we believe to be a comprehensive switched Ethernet solution. Applications for GalNet-2 devices span the range from SOHO products and rack systems supporting full-wire-speed performance, stacking and advanced features, to mini-chassis and full-chassis systems designed to provide enterprise users with full converged networking support. Systems using the GalNet-2 device use our proprietary G.Link bus to interconnect switch controllers and crossbar switch fabrics. G.Link supports development of very high-performance systems via its high bandwidth and our G.Link crossbar switches. Crossbars are used to route messaging and data between distributed switch controllers and, if present, the management CPU complex. Our G.Link crossbar switches range from 4 to 12 G.Link ports to support the development of a wide variety of system architectures. Crossbars may also be interconnected in meshes to support larger numbers of G.Link ports. GalNet-2 crossbars are also used with GalNet-2+ and GalNet-3 switched Ethernet controllers, for advanced Layer and Layer 3/4/5 system applications. GalNet-2 switched Ethernet controllers are available supporting a wide range of features and configurations. These switches are combined with others to build systems with up to 256 Fast Ethernet ports, 32 Gigabit Ethernet ports or combinations utilizing up to thirty-two switch controllers and CPUs. We believe that a major benefit of the GalNet-2 devices is software compatibility among switch controllers. Shorter time-to-market is supported via the leveraging of previously developed code in new system applications, often with little or no modification.
