Shared LAN Cache - An Enabling Technology

In much the same way that new microprocessor designs are limited by affordable memory systems, LAN designs and applications are also limited by affordable network bandwidth. Without the benefit of high speed memory caching, even the fastest processor designs would be limited to 386 class performance. Similarly, without Shared LAN Cache, LANs and WANs cannot keep up with the ever increasing performance demands of new applications.

Shared LAN Cache is a breakthrough in LAN and WAN design. Using a combination of local and shared caching, SLC dramatically improves the performance of existing LANs and WANs without large capital investments. Even wireless LANs can now provide performance comparable to wired LANs!

Our objective is to promote SLC™ the same way Dolby™ noise rejection technology was promoted throughout the music industry to improve the quality of tape recording and playback. SLC™ will be available from a wide range of networking OEMs producing NICs, routers, NOS's, wireless/remote bridging and a new generation of network switches/ATM with SLC™ caching integrated into the fabric.

Key Shared LAN Cache Distinguishing Features

NOS independent - Works with all PC compatible network operating systems.
Client/Server caching architecture with support for both shared and local caches.
Solution for wide range of network performance bottlenecks
- Slow File Servers
- Overloaded LAN Segments
- Inter-Segment Delays Caused By Slow Routers/Bridges
- Wireless LAN Connections
- WANs
Non-Volatile Caching - Both the SLC Server and SLC Client incorporate a non-volatile cache that eliminates the need for redundant data read requests. While most caches in use today are volatile, losing their contents when power is removed, data in SLC's non-volatile cache is retained and available immediately when power is applied.
Shared Cache - This patent pending architecture brings an advanced model of caching to LANs and WANs. Any SLC Client that accesses data from a local or remote file server automatically writes data into the shared cache. The next time an SLC Client attempts to read data from the same file, the request is automatically re-directed to the shared cache off-loading the file server.
Solution for legacy LAN performance problems and at the same time SLC is a critical component in new state-of-the-art network designs.
