The industry-leading LightStream 2010 ATM switch was designed for high-performance, mission-critical enterprise backbone networks carrying data, voice, and video communications in both local and wide area. Based on a high-speed busless switching architecture, the LightStream 2010 is a modular device with fault-tolerant capability. The switch includes sophisticated bandwidth management and congestion avoidance capabilities that enable customers to reduce their wide-area bandwidth costs without compromising the quality of service provided to applications. (LightStream Corporation was eventually acquired by Cisco Networks.)



LynxOS® was chosen as the operating system of the 2010 ATM switch to fulfill numerous requirements:

  • determinism and full pre-emptibility
  • reuse of existing C code software running on BSD UNIX®
  • support for standard communications protocols (TCP/IP and NFS)
  • support for the 68040's MMU (Memory Management Unit)
  • support for virtual memory for lower-priority tasks such as network management, user interface, and maintenance functions
  • development of all applications using Sun workstations
